Modern heaters Penofol type need high-quality fastening. Penofol is polyethylene in a foamed state, it is covered with foil on top. Regardless of the type finishing material: roll or sheet, a special adhesive is used as an attachment. It allows you to save technical properties material at a high level.

Using special glue

When choosing an adhesive for penofol, it is worth considering the type of surface to which it will be attached. The foil cover does not allow draft and heat to pass through. To save heat in the building, penofol is attached with inside for insulation. The air space should be 1 cm. Penofol must be fixed with an air gap.

As a heater, foam plastic with a width of 5-10 cm is used. You need to glue the sheets tightly on a special adhesive composition suitable for the foam. Plastic umbrellas provide additional fixation. A mesh is attached on top.

Advantages

The use of glue for penofol fasteners has the following advantages:

• quickly;
• economically;
• you do not need to have special skills;
• no special tools required;
• holds penofol well, due to its lightness;
• does not lend itself to moisture;
• glue on a natural basis has a high efficiency.

Requirements for glue

A substance for gluing insulation on concrete should have the following features:

• have high level water resistance and connection with the base;
• do not have a destructive effect on the base material;
• not react to environment and the weather;
• be resistant to temperature changes;
• have antibacterial qualities;
• maintain their qualities for a long time.

In order for the material to adhere well, solvents are one of the components of the adhesive. When choosing a means for attaching insulation, you need to rely on the type of surface. A specific adhesive composition is suitable for each material. So, if you need to glue the bath with foam foam, heat-resistant glue is chosen for the sauna. Each adhesive composition that is used when performing internal work, must have a certificate confirming its safety.

Surface preparation before bonding

Before gluing, the concrete should be primed.

It is necessary to prepare the surface correctly for gluing so that the connection is uniform and monolithic. Initially, irregularities, defects are eliminated, cracks are smeared, chips are leveled. To improve the adhesion of concrete and foil-clad insulation, the base is primed. The concrete should be flat, cleaned, protruding metal parts - treated with an anti-corrosive agent.

How to glue correctly?

If the insulation is self-adhesive, it is easy to stick it on. Applying penofol. the usual adhesive is applied to the side without foil in an even layer, thinly, evenly over the entire surface. The edges need to be soaked with glue more carefully so that the insulation does not start to lag during operation.

The insulation is kept for 10 - 50 seconds so that the adhesive has time to set. This way it connects better to the surface. Then penofol is pressed against the concrete, smoothed, evenly distributed until it is completely fixed. The seams must be additionally glued.

Examples of manufacturers

The choice of an adhesive composition that allows you to connect the insulation to the concrete surface. big enough.

In construction work, often using material made of foamed polyethylene izolon, the problem arises of how to fix it. One of the solutions is to glue. Almost all insulating materials such as alufom, penofol and others can be glued, if appropriate.

For example, as in the photo, foil-clad for insulation, it is additionally attached to glue.

How and what to glue.

Usually, the balcony is first insulated with foam plates, on which foil-clad polyethylene is glued.

To do this, you can use the following glue:

• KWIK-BOND
• 88-NP
• Acrol pin
• spray "Neoprene 2136"

The joints are glued or overlapped.

You can glue the styrofoam to the styrofoam or other surface with the following glue:

• CEREZIT CT83
• ANSERGLOB BCX 39
• AQUALIT SK-106 P (polymer-cement mixture)
• MASTER SUPER
• POLYMIN P-20
• STOLIT PC and TYTAN STYRO 753 O2 (aerosol polyurethane)

How to glue polyethylene foam to the wall

For example, to insulate housing, you need to glue the screen to the battery.

The required size of the foil is cut. Penofol with polished aluminum foil 3-5 mm is usually used.

Screen can be docked double-sided tape or stick it on.

Today, it is the most popular adhesive on the market due to its versatility and wide application... Retains its properties in the range from -30C to + 90C, is used both in everyday life and on an industrial scale.

For its correct use, read carefully the instructions for using the glue, it has a large number of varieties.

For a large amount of work, there is glue in packages of 25 kg.

Such as for example:

• glue mix "Facade"
• BOLARS

When building your house, when insulating an apartment, whether it be insulating a loggia or indoor spaces, today foamed polyethylene is widely used. He (only in a different form) is used for insulation sewer pipes or water pipes.

Well-known names such as penofol, penofom, energoflex, isofol, styzol, alufom, faralon ... - these and other materials are the same foamed polyethylene that can be made in different form(rolls, mats, tubes, plates) and with different kinds lamination (for example, foil or lavsan).

This material is used not only for insulation, but also for sound insulation.

In addition to other advantages of polyethylene, its property is also noted as inertness, i.e. the material does not react with other substances.

On the one hand, this is very good, because provides safety for humans and durability during operation. But, on the other hand, this causes difficulties during installation - after all, high inertness is accompanied by low adhesion (adhesion).

Therefore, most often, foamed polyethylene is mounted either using different options scotch tape, or simply nailing it to the surface either with a stapler, or with the help of strips or bars.

Sometimes these methods will not work or will be difficult. So, when mounting on concrete wall it would be better to glue the same penofol, and not to nail it with the help of bars and, moreover, not to try to do it with a stapler.

For gluing together and installing polyethylene foam on the surface, it is worth using special adhesives. Some people try to use universal adhesives(like the Moment) and write that they can do it. But a more reliable result can be obtained with adhesives designed specifically for polyethylene.

Especially for foam rubber and polyethylene foam

One of the options recommended on the market is 152 I-1 Kleyberg glue from the domestic company Ecoline. It is specially designed for the installation of thermal insulation products made of foamed rubber and foamed polyethylene, it is made from polychloroprene rubber.

Although, as the manufacturer writes, the scope of this glue is not limited to these materials. It also has excellent adhesion to steel. Since it is made on the basis of rubber, it is also used for gluing rubber products or for gluing other materials to rubber. In general, if you read the materials of the manufacturer, then glue in general can be extremely useful both in construction or repair, and in everyday life, because in addition to all of the above, it is also suitable for gluing a heap of materials: laminate, linoleum, carpet covering, Chipboard, fiberboard, cardboard ... it is not at all clear whether there is something that this Kleyberg 152 does not glue?

About the operating conditions. The glue is frost-resistant, not afraid of heat (retains its properties up to 100 degrees), resistant to water, acids, gasoline, oils. All this makes it possible to use it when installing foam polyethylene insulation both inside and outside premises, including industrial premises (workshops, garages, stations, etc.).

By the way, those who are going to arrange heat or sound insulation from foamed polyethylene should take into account that it is gluing that allows you to achieve the integrity of the insulation, without cracks and without holes in the material. What cannot be avoided if you use bars, slats, a stapler or something similar.

The Russian market does not experience a shortage of adhesives. It contains an abundance of adhesives of domestic and foreign production, capable of gluing almost any surface. For example, the popular line of adhesives is widely represented. This glue is unique, as it has a wide range of applications for gluing foamed polyethylene, for shoe uppers, for natural and artificial leather, textiles for leather and rubber soles. Universal household glue 152 I-1 is indispensable in everyday life, this glue will help you fix virtually any household breakdown. Waterproof elastic glue is designed for bonding a wide range of materials: rubber and rubber-like materials, leather, fabric, metal, wood and cardboard in any combination. Suitable for bonding chipboard, fiberboard, laminate and plywood. The adhesive can be used for finishing and renovation works in construction, for gluing linoleum, carpets, cork, any other natural and artificial floor coverings to various substrates (cement or concrete, asphalt, wood, chipboard, fiberboard), gluing ceramic tiles, polymer tiles on concrete, wood base, plaster. But even among such an abundance, it is not easy to find a glue that can solve such difficult task like gluing thick or thin polyethylene. This problem often arises for the owners of summer cottages with greenhouses, home craftsmen, car owners, etc. What is the difficulty of gluing polyethylene and is it even possible to carry it out?

Foamed polyethylene is widely demanded in different areas mass material unique properties and merits. One of them is its chemical inertness, lack of response to most chemical irritants. It is a paradox, but this is precisely the advantage of polyethylene in in this case turns out to be a significant disadvantage of the popular material, because it is immune to most adhesives and has an extremely low adhesion capacity. And yet there are ways to join polyethylene surfaces. Let's consider three of them that provide the most durable and reliable connection:

• welding of polyethylene;
• gluing with acrylate glue;
• gluing epoxy glue with an oxidizing agent.

Welding polyethylene

Most reliable seam can be obtained with competently performed welding of this material. What complicates the welding process? The next nuance that must be taken into account: polyethylene is molded hot and under high pressure, reaching hundreds of kg per square centimeter. When welding, it is reheated under normal atmospheric pressure until it melts, and then it shrinks somewhat, complicating the work of the welder. By the type of object to be welded, they distinguish between welding of film and welding of products made of thick polyethylene - canisters, pipes, etc.

Thin plastic wrap welded with a special apparatus or pre-heated improvised devices. In the apparatus, the film is glued together as follows: its joined layers are pulled along a wedge heated to a certain temperature, after which they are pressed against each other with a pair of special rollers. A competent choice of the degree of heating and pressure of the rollers ensure a tight and reliable connection.

If you practice, you can get the hang of gluing polyethylene, even with a conventional electric soldering iron or iron. The latter should work through the paper to prevent damage to its sole. This is done like this: the edges of the film are overlaid, covered with paper and quickly passed over it with the edge of the hot sole of the iron. With the tip of a soldering iron, connected through a voltage regulator, polyethylene is welded even better, and without any paper.

Bonding thick polyethylene is a more complicated process that requires special skills... The best way to heat it up is portable gas-burner who is comfortable to work with. You can also use a hair dryer with a nozzle for a narrow stream of air heated to + 250 ° C.

Welding is carried out in the following order:

• the area of ​​the surface where the work will be carried out is cleaned and dried;
• a polyethylene joint filler is being prepared - it is better if it is a tape of the same material from which the object to be welded is made;
• the edges of the welded seam are heated to the melting stage - they should "settle" somewhat, but it is important not to overdo it;
• an additive is gradually introduced - it is fused into both sides of the seam, in thickness it should correspond to the thickness of the material of the product to be glued;
• the seam is allowed to cool completely.

Bonding polyethylene with acrylate glue

For gluing films or polyethylene products, use acrylate adhesives designed for bonding materials with poor adhesion. It contains a filler made of glass microspheres, which prevents the adhesive from sliding off the place of gluing, so the connection is strong enough after the glue is finally hardened.

Before gluing, the surfaces to be joined must be thoroughly degreased and dried. The adhesive is supplied directly from the packaging. Optimal value temperatures for polyethylene connection - +21 ... + 23 ° С. The glue released from the package must be used within 2-3 minutes, then it will lose its properties. After applying the composition, the surfaces to be glued are immediately docked and pressed. The maximum mechanical strength of the seam will be reached within 4-5 hours. Exposure of a new compound is carried out at temperature values that are in the range of 15 -70 degrees above zero.

The use of epoxy glue when working with polyethylene

Epoxy glue was created, of course, not for gluing polyethylene, but it is often used for this purpose, achieving good results. The fact is that phenol-formaldehyde resin has a fairly high adhesion to polyethylene surfaces.

Technology for gluing polyethylene with epoxy adhesive:

• We carefully prepare the surfaces to be glued, for which we first coarse them with an emery cloth, and then degrease and dry well. Having done this, we treat all working zones with a 15-25% solution of chromic anhydride or a solution of potassium dichromate at a concentration of 20-30%. These chemicals should be handled with great care as they are corrosive and carcinogenic. A strong solution of potassium permanganate can also be used as an oxidizing agent. It is much safer, although it loses a little in efficiency. After completion of the oxidizing treatment, the surfaces are dried again.
• Epoxy adhesive is diluted exactly according to the instructions.
• The adhesive is applied thin layer on both surfaces to be joined thin and docked.
• The element or product to be glued should be kept for several hours at a temperature of 30-45 ° C, and it is even better to increase this period to a day.

Polyethylene is one of the most popular and widely known materials. Not too expensive and, in general, unpretentious. Polyethylene is quite often used in the construction of greenhouses and greenhouses, for insulation and moisture insulation of various objects. At the time of the work, many craftsmen are faced with the need to glue this material. This is where the problems begin. The fact is that polyethylene is difficult to bond. But you can still fasten it with glue. It is also possible to do this under the action high temperature... How to choose a suitable adhesive for polyethylene and what should you pay attention to when carrying out work? Answers to these and other questions can be found below.

Properties of polyethylene

This wonderful material has many interesting properties. Polyethylene is used to protect against moisture, is an excellent electrical insulator and is able to absorb one of the most dangerous types of radiation. It is almost completely resistant to chemicals... It is this last quality that sometimes turns from an advantage into a disadvantage. How to hold such a material together and how to choose an adhesive for polyethylene?

Interestingly, bonding is not only chemical, but to some extent electrical process... The molecules of the substances to be joined are attracted to each other due to the difference in their charges. Therefore, it is quite difficult to find such a substance that adheres well to polyethylene, and after drying it firmly holds the fastened parts together. Since the molecules of this material are quite strongly "balanced", it can be very difficult to glue it with other elements. But anyway chemical industry created an adhesive for gluing polyethylene. And not alone. Such an adhesive must have certain properties. Let's see which ones.

Adhesive material requirements

If you decide to glue polyethylene or penophenol (its foamed variety) to a concrete or brick surface, then the bonding adhesive layer should have a number of properties:

• Remain resistant to atmospheric influences.
• Do not destroy the bonded materials.
• Have high degree hygroscopicity and adhesion.
• Be resistant to temperature extremes.
• Have antiseptic and fungistatistic qualities.
• Retain its properties for a long time.

Consumer reviews suggest that it is also worth paying attention to the environmental safety of the adhesive. This is especially important when using materials for interior decoration premises. And if you decide to use polyethylene (penophenol) when arranging a sauna or bath, you need to pay extra attention to the heat resistance of the glue and its resistance to the action of hot water vapor.

How to choose a glue?

If you don't know which polyethylene adhesive is right for you, ask the seller to look for one that contains methyl acrylate. This substance provides quick softening of polyethylene and its high-quality adhesion. Also, the composition of the product may include chromic anhydride, various acids and xylene. The indisputable advantage of this glue is that when using it, you do not need additional surface treatment. But users argue that it also has a drawback. Such adhesive for polyethylene is very toxic. Therefore, all work is best done outdoors. Well, or you will at least have to provide high-quality ventilation of the room. The glue works best at a temperature of +35 ˚C. He is not afraid of moisture, but he ignites easily.

Also in stores you can find means for connecting polymers. They are sold as a thick paste. They usually come with a solvent. After connecting these two components, the glue acquires the desired structure. Since the solvent evaporates instantly, the mixture needs to be used quickly. So do not breed a lot at once.

But neoprene glue for polyethylene is better not to use. Such a composition is more suitable for joining rubber and rubberized parts, neoprene fabric, leather, felt, ceramics, metal in any combination. But for styrofoam, polypropylene, polyethylene and plasticized PVC, it is better not to use it. There will be no sense.

Filler acrylate adhesive

If you do not know how to glue, try using a two-component composition based on the same methyl acrylate. Alternatively, you can try Easy-Mix PE-PP brand Weicon. It has excellent adhesion properties. It is used for bonding polypropylene, polyvinyl chloride and others polymer materials... You will have to hurry when working with this glue. It retains its properties outdoors for no more than three minutes.

Easy-Mix PE-PP contains a special additive consisting of microscopic glass beads. This filler prevents the adhesive from leaving the bond. Therefore, the seam is strong enough. This glue for expanded polyethylene should be applied only from the mixer of the branded packaging. It is best to work with it at a temperature of +22 ° C. Complete solidification is ensured no earlier than after 5-6 hours.

Epoxy adhesive

Of course, this is not a very suitable glue for gluing polyethylene. But if nothing else could be found, then you can try. You just have to prepare the surfaces first:

1. The edges of the parts to be glued must be "cleaned" with fine emery cloth. Then degrease them thoroughly.
2. Treat both parts with a 20% solution of chromic anhydride or a 25% solution. If such substances could not be found, a strong solution of potassium permanganate can be used.
3. Dry after surface treatment.
4. Dilute the glue according to the instructions. Apply to bonding surfaces with a thin layer. Immediately dock the details.
5. Withstand several hours, and preferably a day - until the seam completely solidifies.
