Mounting characteristics, power and stability. Mounting pin: technical characteristics, generators, curing, ducts, power of mounting pin

Whenever there is a need to fill an opening, seam or gap, the mounting pin is most often used. This material is used for rough finishing, installation of door frames, glass panels, repair of balconies, and installation of various structures (for sealing).

The type of assembly stump is a basic pattern - for different minds, that task.

The product is sold in cylinders of different volumes (from 300 ml to 1 l).

Food warehouse (can be opened up frequently, stored in the vibrator):

1. Prepolymers (polyol, isocionate) are the basis of the foam. Upon contact with surfaces, this component enters into a polymerization process, expanding and shrinking.
2. Propellant (vital gas, mixed with butane and propane). The warehouse comes out of the balloon when pressed.
3. Additives. Additional components that improve adhesion, regulate the stage of spinning, and necessary changes in operating temperature.

Technical characteristics

Technical characteristics of the mounting pin:

• Expanded. It indicates the volume that the sum is borrowing in 2 stages: leaving the balloon and catching up. The greater the expansion, the more thickly the gap (seam, opening) will be filled. Average indicators are 10-60% for household warehouses and 180-300% for professional warehouses.
• Adhesion. Indicates the strength of the warehouse from the surface in the middle of the space that is foaming. The higher the viscosity, the less immediate the foam. It is relevant if you need to seal the openings on a vertical surface (on the wall) or on the stele (the marks of the foam can drip down until it gets stuck). In figures, the normal parameter is considered to be 0.4-0.48 MPa.
• The volume of the container and the liquid at the outlet. Wider parameters: 300 ml (give about 30 liters of frozen water), 500 ml (give about 40 liters of water), 750 ml (give up to 50 liters of water) and 1000 ml (80-100 l). The situation when caught is approximately normal (room temperature).
• Temperature at which the pin can be frozen.

These displays are indicated on the balloon.

Designated sphere of stagnation

The mounting pin will be used in everyday life at the following stages:

• Chornova obrobka.
• Installation of door frames, balcony and window frames.
• Laying of communications (for strengthening between water pipes, sewer pipes, ventilation ducts, gas pipelines and walls, so that there is no vibration).

Their purpose is the sealing of openings, voids, seams and joints between structural elements, if their width exceeds 2-3 cm. Previously, for such tasks cement and shreds were put together, otherwise this method would be more durable and foldable.

Pros and cons of frozen piping as a sealing material

The following nuances can be added to the progress of stagnation:

1. Simple operation (working with a mounting pad does not require special knowledge).
2. The application and curing speed is high (a 300-500 ml container can be dispensed in 5-10 minutes, cured in 3-12 years, and is resistant to moisture and temperature).
3. Ability to work with any type of material, including metal, plastic and polymer surfaces.
4. The mixture will stick to the surfaces (after getting caught, it will be difficult to remove the pin, but if necessary, it can be cut or crushed).
5. Resistance to moisture (the ball of frozen stump does not rot or mold).
6. Detection of warehouses with different characteristics (for different temperatures, with different levels of protection from open fire).

The main disadvantages are its sensitivity to ultraviolet radiation. Under the sleepy changes, the foam dries out over time, otherwise you need to vikorist at the stage of black finishing, and do not deprive it of respect - either lay it with plaster, or cover it with panels (plastic, for example).

Types of mounting pin

All warehouses can be divided into:

• Number of components.
• Method of curing.
• Temperature.
• Flammability levels.

For the number of components

There are warehouses:

• One-component. Sold in cylinders under pressure, do not wring out additional components: the warehouse can be frozen immediately, dispersing its contents.
• Two-component. Sold in 2 different capacities. The containers must be mixed in proper proportions, and the resulting mixture must be mixed using special equipment.

Retail stores have the largest number of products – they have single-component warehouses. Two-component products are used only for industrial purposes, for high-volume operations and when it is necessary to obtain the highest possible characteristics of the warehouse.

Behind the method

There are warehouses:

1. Professional The foam is powdered from the bottle, which is inserted into the gun. A more powerful option, cutting with a pipe, allows you to quickly work with a large volume (for example, sealing cracks between slabs).
2. Professional (casual) drinks. A plastic tube is placed over the balloon, through which it passes. Suitable for minor tasks (for example, filling a gap when insulating a balcony).

Plastic tube nozzles are sold as a set in small packages. They can be frozen a number of times (as work is carried out at a number of stages, as a number of cylinders are being evacuated), for which it is necessary to blow out the tube after freezing (so that the foam does not get caught in the middle).

Mounting pin guns are sold separately. The minimum value is about 300 rubles, the average is 500-800. The device is high-grade, after completion of the work it is necessary to wash it with a special cleaner (acetone). If the foam catches in the middle of the nozzle, it can be removed with a cleaner or cleaned with a mechanical cleaner.

According to the temperature at which you can stick your pin

Depending on the temperature conditions, the following types of warehouses are divided:

• Summer: designated for chilling at +5º…+35º.
• Winter: designated for drying at −18º…+35º.
• Universal: freeze at −10º…+35º.

The temperature of the surface on which the foam is applied is indicated, and not the temperature of the surrounding area. Therefore, when working in the cold (for example, when the balcony is stuck together, or the seams are sealed without scorching or without windows, which will be) it is necessary to heat not the location, but the surface.

Also, the surface temperature affects the mounting surface: the colder it is, the less ready-made material will come out.

Beyond the level of flammability

This is relevant when work is carried out in a place of employment (for example, in the field).

Product classes:

• B1: flammable.
• B2: self-extinguishing.
• P3: flammable.

Popular virobniki

On the Russian market there are products from the following manufacturers:

1. Macroflex (Makroflex, Finland).
2. Bison International (Netherlands).
3. Soudal (Belgium).
4. Tytan, Hauser (Poland).
5. Bau Master, Domos (Estonia).
6. Meister Tsvyakh, CHIP, Putech (RF).
7. Ceresit (Nimechchina).

Rules for installing mounting pins

I need to become a vikorist by following these rules:

• The width of the gap or opening should be in the range of 2-10 cm. Small cracks (up to 2 cm) are best sealed with putty or sealant. It is better to fill wider gaps with whole wood or polystyrene foam, and seal the gaps that are missing.
• When working in cold weather, the balloon with foam needs to be heated: lower it into a container with warm water (up to approximately 30-40º).
• You can cut off the excess only after 25-30 minutes after applying the foam, if it is caught completely. This can be done with a sharp knife.
• The cylinder must be placed upside down, so that the gas is squeezed out of the bottom. If you trim the container with the bottom down, the gas will come out of the container and the foam will be lost.
• After removing the caps and attaching them to the gun (or tube), the balloon needs to be drained.
• The balloon with the “butt foam” is filled with foam in 1 pass – the open capacity cannot be saved for long, it hardens.
• The gap cannot be closed more than 50%, because when it expands it tends to increase.

Folding nuances

So that you don’t have to cut off a large number of stumps and rebuild the structure again, repair:

1. If the opening is 3-4 cm wide or more, apply the kick one at a time: 1 ball at the beginning, after hitting it, step in succession.
2. Open it thoroughly with the foam rather than forget it. It is recommended to cover one side of them tightly (for example, with a board), and remove the lid only 30 minutes after sealing, if the warehouse is caught.
3. When installing door and window frames, they must be secured with dowels and spacers. If you can't build anything, a warehouse that is expanding can warp the box and have to reinstall it.

Etapi roboti

Pokrokovo pinu vikorist like this:

• The surface is cleaned to remove any gritty grease, etc.
• The surface is skimmed (with acetone).
• The surface is coated (sprinkled with water using an additional pen or spray bottle). The pina is thicker and more solid, as it is on the surface (or on the surface) of the fiber.
• If the room is cold, the bottle is placed near warm water.
• The balloon is opened, inserted into the pistol (or a tube is pressed onto it) and shakes off.
• The end of the tube is inserted into the crevice and the foam is fed in portions, 5-10 cm above the crevice, crumbling from bottom to top.
• After being completely caught (after 25-30 hvilins), the pieces that protrude are cut with a paring knife.

Come in safely during work with a mounting pad

The mounting foam is a chemical warehouse that is kept in a container under pressure. Therefore, it is necessary to work with him, adhering to the rules of safety:

1. You can’t miss it or heat the balloon.
2. It is not possible to place the can near baked surfaces or exposed to fire.
3. Carry out the work using mittens (if you rub the pin on the skin, it will be difficult to clean).
4. You need to rub a sponge and a plasterboard under your hand to clean the warehouse before you use it in an “unnecessary” place.

Removed foam when contacted with “unnecessary” surfaces

The mounting foam accumulates on the surface of the seal, so if it has sunk somewhere around the required gap, it will be important to clean it.

Methods for cleaning rubber surfaces:

• Skin. If the warehouse is not caught, it is removed with a sponge, and the excess is wiped off with acetone or a liquid cleaner. If caught, cut off and wipe off with a scrub.
• Fabric. If the warehouse is not caught, it can be collected with any hard object (go to the corners of the board). Once upon a time, the clothes are cut, and the remaining surplus is washed away by the retailer. In both cases, the stitching on the fabric may be lost.
• Plastic window sill, frames, bevels. The fresh stock is removed with a sponge, the excess is washed off with a plastic surface cleaner. The dried ball is cut, the excess is wrinkled.
• Linoleum, laminate. Remove the fresh foam with a hard object (a spatula, a flatbed), and remove the excess with a sponge soaked in cleaner.

To prevent such situations from occurring, it is necessary to protect the skin and surfaces nearby. They should be covered with polyethylene sheeting, plasterboards or newspapers.

Today's everyday Maidans cannot do without a vicarious mounting pin, the technical characteristics of which have played an important role in their mass stagnation. Professional workers and amateurs, who wanted to deal with repair robots on their own, recently cannot imagine the installation of doors, ceilings and windows, as well as everyday entrances, associated with waterproofing I have pipelines with large capacities, for example, water heating tanks and bathtubs, without The installation of the mounting pin, the vikoristan technology, which will be examined in the statistics.

Mounting pin: performance characteristics

Everywhere, the use of mounting pins is, first of all, determined by its operational characteristics, which make this material indispensable in practically all types of everyday work. The main advantages of the assembly line, immediately recognized by its advantages, as it is possible to evaluate the skin wake-up, lie in the future:

• Possibility of vikorstan is like the sound of a heater;
• High resistance to moisture and low conductivity of electrical current;
• The operational features of various types of mounting pins include resistance to wear;
• After expansion, it is important to fill empty and loose cracks, ensuring high strength of seams and joints;
• Possibility of gluing elements made of different materials behind an additional assembly pin.

Types of mounting pins

Today, manufacturers produce a number of different types of polyurethane mounting foam, including the following varieties for everyday use:

• A professional mounting foam, for this type of vikoristan there is a specialized device - a gun, which allows you to increase the yield of polyurethane sealant and prolong the term of its vikoristan;
• Pobutova or non-professional polyurethane mounting foam is intended for disposable use. In addition, the main usefulness of the rubble sealant lies in the significantly lower thickness of the cylinder’s surface.

According to the temperature conditions for which it is permissible to apply the mounting pin, the video from this article is presented in the article, there are the following varieties:

• The summer mounting foam will stagnate when the temperature of the sprayed surface varies from +5 to +35 degrees;
• Winter mounting foam can be winterized, since the temperature of the wet surface varies from -20 to +30 degrees;

• The all-season installation is characterized by winter and summer modifications according to the authorities. The all-season operating temperature is between -10 and +30 degrees.

Moreover, to the workers who have given priority to the mounting pin, the manufacturer pays attention to a wide variety of polyurethane sealant, which has specific functional parameters - the same as the mounting pin. The use of a non-flammable sealant, which retains its performance characteristics at high temperatures and open fire, is practiced in everyday life of objects whose fire safety is most important in imogi.

How to choose the right polyurethane sealant?

When choosing a mounting foam, the price of which will definitely lie in the frame, it is important to focus not only on the manufacturer, but also on the current characteristics of the container in which the sealant is sold. The thickness of the foam is very important, and when fluffing it will transfer from one end of the balloon to the other, and the price will speak for itself.

Officials, what to pour onto the mounting pin

An important parameter that is recommended for contractors when selecting a sealant is the wastage of the mounting foam. It really depends on the quantity of material that needs to be added to carry out these and other operations and is determined by the large number of external and internal factors.

Internal:

• The generator of the assembly pin, which contains one of the important technical parameters of the material, is the first expansion. Apparently, there are modifications that are greatly expanded to include most household sealants, for example, Titanium mounting foam. In addition, producers use mounting pins with medium and low extensions, suitable for more delicate operations, such as the Macroflex mounting pin, which has a greater distribution of power, as well as mounting pina Meister, which is characterized by minimal toxicity.

External:

• Temperature of the middle core;
• The material that is used to prepare the surface that is being formed is determined by one of the main parameters that needs to be handled when unrolling and applying the sealant.

Instructions for installing the mounting pin. Basic subtleties

Regardless of which assembly pin you have given the advantage, whether professional or everyday, before the vikoristannye foam container is first heated in hot water and thoroughly dried. It is important to mix the components of the sealant, and thereby increase the output of the mounting pin, a photo of which is presented in the article.

Further steps must be taken to modify the prepared polyurethane sealant.

Since it is a professional foam, then the tube that comes with it in the kit is put on the balloon, so that the balloon from a professional foam must be installed on a new gun after being removed from the new cup.

It is important to remember that the gun is functioning properly and will ensure the preservation of non-corrosive foam for a length of 3 dab.

After preparing the material, it is necessary to carefully prepare the working surface, which is ready for applying the sealant. It is a good idea to clean them from the waste and saw particles, and also moisten them with water, which will speed up the polymerization of the polyurethane precursor, which enters the sealant storage area. In addition, it adheres until the mounting foam sticks to the wet surface.

The process of applying polyurethane sealant is not complicated, but you need to pay special attention to the correct proportioning of the outlet from the container.

In this case, it is easier to work with a professional foam, the tank is equipped with a special gun that regulates the flow of sealant through an additional valve. When using commercial cylinders, this process is regulated by pressing the pressure on the cylinder valve. It is important to ensure that in the process of applying foam to the surface of the balloon, it is necessary to trim it vertically with the valve down.

After applying the sealant, it is necessary to ensure complete drying. As the polymer hardens, complete polymerization of the material takes 6-7 years, but the remainder of the process often remains in the water, which cures and can last up to 11-12 years.

After the mounting pin is caught, many people ask: “How to remove the mounting pin?” This approach also does not require special skills. Excess stumps that were lost after being caught should be cut with a metal saw or a sharply sharpened knife.

If the mounting foam was installed on the street, after residual drying and further removal of excess, it should be coated with cement or plaster. Also, its preparation is not blocked, which protects it from ultraviolet radiation. The need for this approach is due to the high sensitivity of the shortest mounting pins to ultraviolet exposure, which accommodates changes in color and pre-washed material.

If, when the mounting pin is applied, it touches your hands, do not panic. You can get it from the help of a dealer who is hired to wash the pistol.

The mounting pin is a durable material that takes the greatest width and hardness out of the box for the rest of the time. In one bottle, the strength of craftsmanship and unique installation power are demonstrated.

A lot of mounting pins were in action, although they were not damaged. There, where everyday life is carried out, behind the contours of the windows and doors you can add a thick material similar to polystyrene foam. This is caught by the mounting pin.

Mounting foam is a one-component polyurethane foam sealant in aerosol packaging. To speed it up, just add a can, direct the outlet tube into the empty container to seal it, and press the button.

How does adhesive-sealant work?

The pins, under pressure, enter the crevice, and over the course of many years they will expand, completely filling their own space and sticking to the surface.

Previously, instead of replacing the mounting stump for laying empty beams and joints, cement was put together from shreds. The effectiveness of such an arrangement compared to current methods is, at first glance, doubtful. And the installation process will be long and not painful.

Now everything is in the past. Pina literally used the same materials and methods that were used to seal seams and joints in the past.

In addition to sealing the foam, it plays an important role in installation. It fits tightly together with most traditional household materials, gluing the surface one by one in this way.

Some materials cannot be interlocked

We cannot judge with any real materials, through our power and chemical activity. Axle and materials:

• teflon,
• silicone,
• polyethylene,
• polypropylene.

Importance of vologosti

The externally hardened foam lasts for at least 24 years. This process is called polymerization, and in one of the reagents it is water that is in the atmosphere.

For quick polymerization and preservation of large empty parts in the middle of the assembly seam (in the middle of the stump ball), manufacturers recommend soaking the surface with water before curing the stumps.

The mounting foam also holds two more brown berries. It is insulating and soundproofing. The seam, filled with assembly foam, will be heat-saving, the bottom of the same door or the glass package.

Classification

Mounting pins currently sold are classified according to the method of hardening.

Apply professionally with the help of a mounting gun (sold separately). This does not matter to professionalism.

They are also divided into:

• in winter - it stagnates until the outside temperature indicator is 18 degrees;
• summer, - the recommended temperatures range from +5 to + 35 degrees C;
• all-season, - when stored in a warehouse and vibrating, the frozen temperature may change.

Why bother?

• Insulation.
  Filling cracks in walls and roofs, between rows of insulating materials.
• Reinforced, laid seams.
  Lays seams around the perimeter of windows and doors. The pipes in the installation shafts are strengthened.
• Installation, bonding.
  Fastening (additional) door hatches and window frames at the openings. Gluing materials (insulating, decorative) on the walls.
• Noise reduction.
  To reduce noise and vibration, install pipe joints between walls, fastenings of air conditioners, hoods, and pumps.
• Decorations.
  The mounting pin is used as a stand-alone decoration, and serves as a basis for the production of folding frames for the design.

In order to avoid the desired effect, such as hardening of the mounting pin, it is necessary to apply it correctly, and remove the material to insulate it by pouring direct sonic changes and water.

Protect from water and sun

The main disadvantages of this everyday material are those that decompose under the influence of ultraviolet radiation and pass water through it, consuming their power.

This mounting pin needs to be protected, the scalded seams, which are susceptible to such spills, with waterproofing materials.

For example, when installing plastic windows using classical technology, it is necessary to insulate the seam around the perimeter:

• call waterproof and vapor-permeable stitching,
• in the middle of the room there is a vapor barrier.

In this type of joint, the adhesive-sealant as a heat insulator and strengthener for the window seam will last a long time.

Details

When buying a spray bottle, you need to be careful of particles. As popular as the product, so popular is its subdivision. The simplest way to cheat is to underfill the cans.

So, in the race for price, you can even make a mistake.

Persh Viberi Vibrati to the installation of PINA, especially for the gate of the great measurements, it is recommended that they are diluted at the Mixtsevich Budielnikvy, the duma of the same vibration, specific parties, Pslya Chogo Robiti Svibir.

Before zastosuvannyam

Please read the instructions carefully from the mounting pin on the transmitter package. Be sure to follow the rules for composting this material.

In most situations it is recommended to do this.

• Stay safe! Practice with mounting foam only in mittens and dry eyepieces. Remember that in rare places the speech is even more safe!
• Use vikorist foam to fill gaps of medium size (1 - 8 centimeters). If the gap is narrower, then it is better to use a classic sealant, which is wider, better to replace the piping and harden more cheap materials - cement, polystyrene foam, stone, sand and cement.
• Before hardening the mounting foam, wet all gluing surfaces with water. As has already been said, without sufficient moisture in the back (80%), a normal reaction is not possible, and you will waste the material for nothing.
• In advance, vigorously blow off the spray can for at least one length of time. This way you mix the rich component warehouse in the middle of the can.

Yak vikorystuvati

• Pump up the foam by placing the balloon upside down! Otherwise, you will not release the empty container of the tank, but then release the gas.
• Remember that the foam significantly expands during the first period of hardening, increasing its capacity 2 to 3 times. Then the process of step-by-step change of duty begins. Occasionally, you will remember one third.
• If the space is tight, re-insert the cylinder fitting completely and evenly. Don't rush. If it is possible, then start a small plot and check out from scratch to see how a particular warehouse works. This will help you make the necessary improvements with a lot of further work. Vertical gaps are about to collapse from the bottom to the top.
• It is not recommended to mechanically tighten (uncut, vibrate) foamed seams for at least 24 years. As it is written on the packaging, the warehouse reaches the warehouse within 3 years. This means that after laying the window seam, the window cannot be opened with another piece.
• After foaming, it is recommended to sprinkle the foam with water to speed up and reduce all reactions from the hardened foam.
• Excess hardened foam is removed with a knife. The warehouse is then covered with insulating materials in accordance with current recommendations.

Also remember about the high stickiness of pins. Through carelessness, you can seize both your clothes and any materials that you can use to soak up the waste.

We sell special washers for mounting pins. Ale stench is weakly effective, often deprived of stains and washed away from the warehouse with varnish and farb.

If you catch the river, you can clean it with a guest object, cutting it on its surface. It's hard to see why.

Today's everyday Maidans cannot do without a vicarious mounting pin, the technical characteristics of which have played an important role in their mass stagnation. Professional workers and amateurs, who wanted to deal with repair robots on their own, recently cannot imagine the installation of doors, ceilings and windows, as well as everyday entrances, associated with waterproofing I have pipelines with large capacities, for example, water heating tanks and bathtubs, without The installation of the mounting pin, the vikoristan technology, which will be examined in the statistics.

Characteristics

Everywhere, the use of mounting pins is, first of all, determined by its operational characteristics, which make this material indispensable in practically all types of everyday work. The main advantages of the assembly line, immediately recognized by its advantages, as it is possible to evaluate the skin wake-up, lie in the future:

• Possibility of vikorstan is like the sound of a heater;
• High resistance to moisture and low conductivity of electrical current;
• The operational features of various types of mounting pins include resistance to wear;
• After expansion, it is important to fill empty and loose cracks, ensuring high strength of seams and joints;
• Possibility of gluing elements made of different materials behind an additional assembly pin.

Types of mounting pin

Balloon valve with foam

What is the mounting pin?

Virobniks produce different types of mounting pins, which differ in storage, operational characteristics and area of ​​drying.

Tim not less, intellectually, the pin can be divided into (description of the mounting pin):

Professional

Balloons with such foam are equipped with a special ring valve, which serves to screw the container onto the mounting gun. After the balloon is secured to the tool, the foam, under pressure, presses into the middle of the gun, where it rests against the valve, which is attached to the trigger. Once the gun is used, the procedure for applying the foam to the working surface is made as comfortable as possible. By pressing your finger on the trigger, you can control the pressure directly.

Pobutov.

The set of such balloons includes a special plastic tube, which allows the robot to be removed without a special gun. However, regardless of its simplicity and accessibility, for most parameters it is strictly sacrificed to a professional. Zokrema, she has a much larger display of secondary expansion and a lower one for the exit. Often, such cans will run out of gas sooner than the prepolymer. Until then, they are considered disposable, so it is necessary to destroy them at the same time, as the remaining capacity becomes completely unsuitable for work. Thus, it is best to be generous to buy an assembly gun, which costs several hundred rubles.

Please note that it is strictly not recommended for everyday work to install essential work, such as installing window and door structures, as well as subfloors.

In addition, the warehouse of assembly stumps can become its own warehouse:

One-component– tse zvichna is available for zagalny koristuvannya.

Two-component– this species is limited to a narrow sphere of stagnation and cannot be sold to the public. So, for this purpose it is necessary to mix two different warehouses.

It is also important to note that there are temperature drains in which the mounting pin can be stuck, there is:

• Summer.
• Zimovy.
• All-season.

It should be noted that the stock of winter foam is significantly different from its summer counterparts. Zokrema can be used at low ambient temperatures, up to -20°C inclusive. Naturally, for stagnation in such a frost, it is important to ensure that the temperature of the cylinder itself is positive.

In addition, the foam is divided into flammability classes and has similar designations:

• B1 – igniter.
• B2 – self-extinguishing.
• B3 – flammable.

Of course, the most important thing is the mounting point, which may advance the power supply.

How to buy a mounting pin for the size of the cylinder and the distributor

The strength of the mounting pin indicates how much work can be done on one cylinder. The store has the following options:

• 300 ml – yield is about 20 l. This amount is enough to seal the box when installing a standard window 1.2 x 1.5 m;
• 500 ml – yield equals 35 l. Grind the volume of the balloon onto a door frame measuring 0.8 x 2 m;
• 750 ml - the yield value ranges from 40 to 70 l. This amount is enough to install approximately two doors or three windows.

As the evidence of wealthy wealthy people shows, it is better to buy a bottle of a little more than necessary goods, but then realize the inadequacy through the marriage of funds.

The information about the output of the stink is indicated in orientation, the fragments of the stink can be changed due to the peculiarities of conservation or washing. Also, a vibrator is poured into the display (a cheap brand will give you a maximum capacity of the container for a maximum capacity of 20 liters).

To avoid making a mistake in your choice, give preference to well-known brands. These names are especially favored by buyers - PROFFLEX, Orion, Soudal, Krimelte, Henkel.

Sometimes, balloons are collected without indicating a specific source and with a single inscription on this topic - “Made in Europe/Russia.” Fahivtsi do not recommend purchasing such products, as the fragments of the mounting pin are very likely to appear unclear.

For any reason, you have to buy a product of a cheap and unknown brand in order to compare its products with a good brand. With the same size of the container, the pressure on the mounting pin is approximately the same: this indicates equal durability of both containers.
Major repair and maintenance work cannot be carried out without the right tools. The mounting pin is the same point that needs to be selected carefully.

Why is the mounting pin one-component?

Behind the warehouse there are two types of mounting pins: one-component and two-component. The first one is much more frequent, and the second one is much simpler and easier. The one-component foam is packaged in an aerosol package and, in essence, with a polyurethane sealant. In this case, in essence, the speech in the balloon is a crazy amount of dozens of speeches. The base of the foam is synthesized from an isocyanate and a polyol, and as a result, it is extracted with a prepolymer. A chemical reaction often occurs in the middle of the balloon, or even more so upon contact with wind, resulting in the creation of polyurethane. The release agent for any polymer is a mixture of liquid gases (butane, isobutane, propane), which is called a propellant. At this point, there is always a pressure before the prepolymer leaves the container.

When leaving the cylinder, the warehouse through contact with the surface transforms into foam and increases in volume by 20-40 times. Due to the sharp expansion, this pin is designed to fill with itself the important accessible empty parts. For a short period of an hour, the mass is firmly through the water, so as to avoid the wind. To increase the fluidity of the hardener, you can soften the surface itself when applying the mixture. To complete the chemical reaction, the warehouse needs approximately one hour to harden the foam, transforming into chemically stable polyurethane. The great advantage of this word is its value, durability to the pulp, and also its low cost. Due to its porous structure, polyurethane is an excellent insulator.

The installation pin can be installed almost instantly using any everyday material: concrete, stone, mortar, wood, plastic. This allows them to be included in the widest range of building and installation work: installation of windows and doors, heat and sound insulation, sealing of studs, crevices, water pipes, and also, if necessary, sealant isolation of certain elements.

There are currently a wide variety of mounting pins on the market that will better give preference to well-known brands. Among them:

• Henkel (trademark Makroflex, Finland)
• Bison International (Netherlands)
• Den Braven (Netherlands)
• Soudal (Belgium) international concern Tremco lllbruck
• Selena Group (trade brands Tytan, Hauser, Poland)
• Bau Master (Estonia)
• Domos (Estonia)
• Okyanus Kimya (trademark Soma Fix, Turechchina)
• "Germetic-Trade" (trade marks "Meister Tsvyakh", CHIP, Putech, Russia)

Pay attention to the fact that the clear mounting foam, when applied to the stain, is fixed on the surface and does not flow down it. Another indicator of brilliance is its value: when exposed to low temperatures, the clear mounting pin does not break or crack.

Pros and cons of the mounting pin

Let's talk about advantages of mounting pin:

The mounting pin will be stuck in place heat and sound insulator;

Pina is a rich material, which glues differences in the material of the element;

Mounting pin do not carry out electric shock and stand until exposed;

Several types of mounting pins resistant to getting busy(B1 – anti-burning pina, B2 – self-extinguishing, B3 – burning);

Expanding mounting pin all cracks and empty parts will be repaired This is why the seam turns out to be very bright.

well and disadvantages of the mounting pin offensive:

— When exposed to ultraviolet radiation, it starts dark and crumbling that pin needs to be covered from the sun for additional putty;

— When a foam gets on the skin, it is only lifted off by the handler and if the foam has not yet been covered. Any foam that has caught on the skin can be removed with a piece of pumice before steaming the skin.

How to get rid of the assembly kick?

Before you work with the mounting foam, you should put it on your hands mittens, because it is problematic to remove the mounting pin (more has been written about this). Then, they put on the mittens, took the balloon from the foam, took off the cap and screwed it onto the new gun, as it is a professional foam, just as they put an adapter tube on the balloon. Only after this is required cowardly balloon with a length of 0.5-1 hvilini, so that the foam is well mixed in the middle of the balloon, if you can’t create something, then the balloon contains resin, not foam.

Before recording the following wet the crevice with water for quick removal of the mounting pin. Then we proceed to the recording. The cylinder should be kept upside down so that the gas in the cylinder hangs out of the cylinder, otherwise all the gas will come out of the cylinder, and the foam will be lost in the cylinder.

Fold the gap no more than 5 cm in the edge, if the gap is more than 5 cm, then it is necessary to seal polystyrene, thereby saving the mounting pin and avoiding the excessive expansion of the pin, which can cause the structure, window sill or door frame to become deformed.

Save the trace up and down, Fill 1/3 of the depth of the gap, so that when flattened, the foam will expand and fill the entire depth of the gap. As robots vibrate in sub-zero temperatures, the winter season is followed in front of the robot warm up In a container with warm water, the water temperature should be around +30-40°C.

After filling the gap sprinkle the foam with water for quick removal of the mounting pin. At sub-zero temperatures, it is obviously not good to sprinkle the foam with water; the water will not give such an effect of rapid dumping of the foam, as at positive temperatures, it is simply freezing.

If the foam has sunk into the structure of windows or doors, or the foam has sunk onto the frame or furniture, then it is important to take gantry soaked in retailer, and press the foam, otherwise the foam will catch and stick well to the surface. It will be even more problematic to remove the foam from the surface of doors, windows and furniture.

After 30 minutes, the foam will be ready for cutting off excess and plastering. It’s really easy to cut a pin for help wood hacksaws or else with a beaver knife. Excessive flattening of the mounting pin occurs after 8 years.

The axis and everything you need to know when working with a mounting pad.

Professional or casual mounting pin?

Each tip comes with a plastic applicator. For professional sealant, a mounting gun is required. Tse dodatkova vitrata. How will you save money?

1. With the stated requirement, the balloon with professional mounting foam has more polyurethane content. That's a fact. To set one option, you will have to use two or three balloons with everyday foam with a volume of 750 ml or one balloon with professional foam with a volume of 750 ml.

2. The professional mounting pin is divided into significant primary expansions and minimal secondary ones. In the butt stump, the primary dilation is insignificant, and the secondary one is greater, as one would like. It’s also easier to work with professional sealant. The installer immediately pumps until the foam fills the empty space. You can control its volume. And with the second expansion, the high pressure on the permanent structure is minimal.

One more moment. It is not difficult to seal a container with professional installation sealant at one time. The shutter in the middle of the gun nozzle prevents the sealant from getting in. This is handy, since a worker, for any reason, has to contribute for a number of days.

Officials, what to pour onto the mounting pin

An important parameter that is recommended for contractors when selecting a sealant is the wastage of the mounting foam. It really depends on the quantity of material that needs to be added to carry out these and other operations and is determined by the large number of external and internal factors.

Internal:

• The generator of the assembly pin, which contains one of the important technical parameters of the material, is the first expansion. Apparently, there are modifications that are greatly expanded to include most household sealants, for example, Titanium mounting foam. In addition, producers use mounting pins with medium and low extensions, suitable for more delicate operations, such as the Macroflex mounting pin, which has a greater distribution of power, as well as mounting pina Meister, which is characterized by minimal toxicity.

External:

• Temperature of the middle core;
• The material that is used to prepare the surface that is being formed is determined by one of the main parameters that needs to be handled when unrolling and applying the sealant.

Peculiarities of installation of mounting pins

Construction and installation work is often carried out in unsafe conditions, including at low temperatures. For such winters, plant growers have broken down the mounting pin, which is intended for recovery during the winter period. It is caught in low wind conditions, and can also be experienced in a wide temperature range. The downside is that the expansion is weaker.

Since work needs to be carried out in winter, and special winter days are required every day, workers have to resort to tricks. For example, stench can contaminate the working surface of the spray bottle. However, before using such methods, you are in an extreme situation: it would be more rational to purchase a special warehouse or wait for a favorable hour to carry out the work.

Varto vrakhovuvat so those who during the hour of work in the winter froth, the temperature of the balloon is about 20ºС. If the balloons were preserved in a cold place, they need to be brought to the required temperature in warm water, without allowing excessive heating (this can cause the balloon to swell).

Uvaga – “spaghetti” effect

Installers and service workers have a term known as the spaghetti effect. Vin means incorrect exit of the mounting pin from the cylinder. As a rule, this is not the case with cheap, unclear pistols, the tips of which do not open all the way, as a result of which the foam comes out as a thin piece. In this way, instead of the soaked thick ball, the stump comes out, which looks most like a thin pasta, which is why the effect is called. The viscous gas flows smoothly, and the mass does not become sour enough and at least not foamy. As a result, the finished product has much less processing time, and its bitterness deprives it of its flavor.

How to save your balloon?

It is necessary to save your professional skin by not removing the canister from the gun, so that it does not dry out at the exit opening. It is necessary that the nozzle of the mounting gun is hermetically sealed. The gun itself must be protected from the surface by closing the valve all the way.

It’s easy to work with the tube foam - if you’ve already used the balloon, it’s not easy to remove the tube from it.

Otherwise, the warehouse that becomes empty at the exit door will be caught and will cross the normal exit.

If you fill the tube with a twisted one, it can be lost - the excess pine in it will dry out and block access to the acid. It is likely that the nozzle will not harden, and the nozzle will no longer work.

How to clean the gun?

There are two ways to clean the mounting gun:

1. From a special product that cleanses, which is sold in the same bottles as the foam itself.
2. Mechanical cleaning.

The cleaning cylinder is screwed onto the standard place of the mounting gun. Then, by pressing the trigger, it passes through the operating mechanisms of the gun, thereby cleaning the exit hole and other parts of the gun.

If you have recently sanded with a gun and the foam in the middle has not yet hardened, then go for a quick clean. In these situations, if it’s a difficult time to remove the balloon, then it’s better to use a cleaner for the stump that has hardened.

Mechanical cleaning It will get stuck if the foam in the gun has dried out and the surfaces cannot be cleaned with it. What kind of gun is it for? to the screw"from the front and back side.

The procedure for cleaning the mounting pin gun:

After the above described manipulations, the internal parts of the gun will become accessible for cleaning. When finished, you need to unscrew the upper gearbox and carefully remove the plastic bushing from it using hand tools. After this, you can remove the valve spring and locking block.

All parts and the gearbox itself are carefully cleaned to remove any excess foam in the middle. This will complete the procedure. The folding of the tracks is carried out in reverse order.

Important to know: it is important to avoid mechanical cleaning for prevention.

The gun is thoroughly disassembled, all parts that are exposed to foam are cleaned.
