Adhesive compositions refer to a fairly easy-to-use means of connecting billets and details of the of different types. The heat-resistant metal glue in this sense is no exception, since it allows you to do without a welding procedure.

Unlike previous times, when adhesive substances were prepared mainly from natural components, modern manufacturers prefer to use synthetic polymers.

Heat-resistant adhesives belong to the category of special chemical compounds, distinguished by a high degree of resistance to elevated temperatures.

Terms of application

With the help of heat-resistant compounds, if desired, you can glue not only metal, but also such durable and solid materials, like glass, ceramics and bricks. After gluing the blanks in conditions of strong heating and the subsequent sharp cooling, the fastening properties of such adhesives are practically not changed.

The advantage of heat-resistant glue allows it to use it with various construction and repair operations:

The operational characteristics of heat-resistant metal adhesives depend on the set of fillers included in them and other components.

Thus, the presence of sand, cement and special plasticizers in the glue, cement provides its resistance to mechanical deformations. And the introduction of special synthetic additives significantly increases the heat-resistant quality of the fastening agent, which perfectly glues the metals in conditions of elevated temperatures.

Characteristics of the adhesive composition of the type "300"

High-quality heat-resistant adhesives used for metal under conditions of high-temperature operating mode have the following performance:

• uniformity (linearity) of expansion in various directions;
• the lower boundary of temperature stability - 300 ℃;
• high exposures of wear resistance, moisture resistance and thermal conductivity;
• ecology and versatility, allowing to use heat-resistant glue in any form of finishing work.

When using heat-resistant mixes for gluing droinen materials (from metal and plastic or metal and bricks) should be worried about each of them satisfy the heat resistance conditions.

The heat-resistant composition for gluing metals of type "300" is sold in branded tubes of a particular container and configuration.

Features of the compositions

Not long ago during the construction brick oven Or the fireplace as a binder mixture was used cement or refractory clay. Currently, under the organization of furnace work apply heat-resistant adhesivescapable of performing their functions at temperatures up to +1000.

Choosing a glue for metal or ceramics, providing reliable grip of building components, its chemical activity should be taken into account (toxicity).

The lower the toxicity indicator at heat-resistant glue, the more suitable it is suitable for use in the conditions of residential premises.

We also note that some manufacturers of heat-resistant mixtures are added to them a refractory clay, which ensures a reliable adhesion of glued materials.

To increase the strength of the compounds formed into certain types of heat-resistant glue, a special reinforcing element is added, which can use chamotte fiber, for example.

The need for this product most often occurs when constructing furnaces from chamotte bricks, which usually lay out the fuel chambers of these buildings.

For facing heating systems Ceramic tiles are used similar to the structure heat-resistant glue.

From the previously discussed samples, it differs in that it contains special synthetic additives, providing increased plasticity of the working layer.

These same fastening formulations can be used when installing the elements of a warm floor in order to ensure their reliable fixation on an arbitrarily selected rigid base.

Aluminum gluing

Before choosing suitable aluminum glue - it should be remembered that this metal is very complicated in the processing (including its gluing). The fact is that in the normal state on the metal surface, there is always a solid oxide film that significantly reduces its adhesion with adhesive mixture.

To obtain the desired result, it is necessary to worry about the preliminary preparation of aluminum surfaces for gluing. To do this, they should be processed by special chemical compositions, Which is most often used with rhymes and acids.

Sometimes for these purposes, mixtures based on epoxy resins are used.

Among the known metal adhesives, a two-component mixture is most preferred based on epoxy or acrylic components supplemented with hardener.

To obtain a qualitative connection immediately after processing with chemicals (before gluing), the surface is degreased, and then coated with a layer of special primer.

In the preparation of the metal, it is necessary to ensure that glue and primer to mix when mixing would be reacted with the formation of an undesirable chemical compound.

In addition to two-component glue, a wide distribution received another kind of heat-resistant adhesive for the treatment of aluminum, called in the surprise "cold welding".

This composition is very convenient to use, but does not allow to obtain the desired connection strength. Due to the specified restriction, the main area of \u200b\u200bits application is close to minor slots and cracks.

Famous brands

Among the most popular heat-resistant adhesives, it is possible to highlight the glue, indicated as "d-3142". This product is made by the Russian enterprise "Diol" and can be reliably glued ceramic tiles To elements of metal furnace equipment.

The glue prepared on the basis of this composition is characterized by increased elasticity and retains the form well. It can withstand long heating to + 850 ° and can be used for 3 days after kneading.

Another productive product is the glue "Moment Epoxylin", withstanding high temperatures, the production of well-known "Henkel".

This two-component composition is made on the basis of epoxy resin And it is intended not only for gluing metals, but also for repair of ceramics and other fragile materials.

Aluminum is very durable, light metalHigh resistant effects ambientBut at the same time completely does not possess adhesion. Even until recently, gluing aluminum parts was not possible, but thanks to industrial progress, stepped far ahead, this method of fastening is gaining popularity, leaving behind different kinds Road. Adhesives for aluminum in its composition contain acids and alkali in required quantitywhich destroy the oxide film of the metal, increasing the adhesion, and increasing the strength and durability of the compound.

This is definitely a huge plus, because any welding requires professional skills, but we are accustomed to glue from childhood. Moreover, more and more often aluminum is used in production: window Rama, profile, pipes, doors, windows, office partitions and much more. Constructions are lighter, and much cheaper analogs.

Types of glue and selection rules

Optimal to work with aluminum adhesives on a polyurethane or epoxy basis. They contain chemical substancesproviding reliable fastening.

Adhesives for aluminum on a polyurethane based class on:

• One-component, their composition includes polymer polyurethane, without solvent. This type of glue is used on open elementswhich are pre-sprayed with water. When reacting with a wet surface, one-component adhesive bases solidify, providing a solid connection.
• Two-component polyurethane based. Unlike one-component adhesive compositionsThis type of adhesive already contains a hardener and does not require additional water manipulations. Most often used in enclosed premises. The composition of the racks to the action of oils, mold, fungi, and also has sufficient heat resistance and high elasticity.

There are also adhesives for aluminum on a resin-based basis:

• Two-component on epoxy basis. This type of glue has high adhesion and heat resistance, so it is most often used in external installation of aluminum structures, or when gluing materials with various thermal expansion - stone, wood, china, etc. Here it should be noted that the lasting connection between various materials Get difficult. Therefore, it is recommended to apply in addition to the adhesive and mechanical connection, for example: with an elastic tape. The glue compositions on a resin-based basis are cold and hot solid and, depending on the scope of the application, select the necessary type of gluing. Cold compositions harden at temperatures from +15 to +350, hot at a temperature of +1000 degrees and often applied at industrial enterprises.

It should be noted that any two-component adhesive compositions are mixed with a hardener, usually in the proportion of 1: 1. But sometimes to achieve a moving connection, the kneading formula may vary, the variations of which are indicated on the product label.

When choosing aluminum glue, pay attention to the parameters specified on the package:

1. The heat resistance, and depending on where the glue base will be used, select the right product.
2. Water resistance, provided that the base will be in contact with water.
3. Is it possible to fasten with different materials.
4. The opening time, which depends on the composition and temperature of the application, and varies from a few minutes to an hour.

Be sure to check the product tightness and shelf life.

Aluminum is a light metal used in industry for decades. During this period of time, it was found that cold welding for aluminum and its alloys is the only way to connect billets.

What is cold welding?

Cold welding is a method of connecting metal parts, which is produced without heating, under pressure. Bonding is carried out due to plastic mass deformation and its penetration into the welded surfaces. Cold welding for aluminum is widely available and does not need special preparation and complex equipment. The process is performed directly indoors at room temperature. No heating sources used by arc welding are required.

Composition and characteristics

Cold welding, in fact, is and may have a one-component or two-component composition, which includes:

• Epoxy resins that make up the basis of welding and responsible for the homogeneity and plasticity of the composition.
• Metal component as filler.
• Additional substances and additives that improve adhesion, resistance to aggressive medium, temperature characteristics and so on.

Strength depends on its composition, the correctness of the use and quality of surface preparation.

Under the appropriate conditions, the connection site is even stronger than the metal combined, but, as practice has shown, seam after gluing an order of magnitude less durable than with traditional welding. Therefore, it is recommended to be used only for a small repair.

For aluminum, "occurs in almost every economic store - A huge number of foreign and domestic producers produce this composition, differing among themselves only by external design.

Mastic, as a rule, is sold in the form of a two-layer bar, which resembles plasticine, or for convenience is placed in cylindrical packaging.

Before welding work Sliced \u200b\u200bfrom a piece (strictly perpendicular) the right amount. Welding elements after kneading hands are quickly applied to the desired area.

Principle of welding deformation

Bonding aluminum surfaces is made due to plastic deformation.

Connected items during cold welding are squeezed very tightly with each other, as a result of which the outer layer is destroyed, an intermolecular connection arises, which forms a solid compound.

To ensure a better connection, the details are preferably deprive in advance, clean from dust.

Methods of cold welding

Aluminum compound technology with a cold way can be divided into 3 methods:

• butt;
• point;
• suture.

Shock welding

With this method, aluminum blanks are placed and clamp into special sponges. Next, they are supplied to them, which is directed along the axis. As a result, the details are most closely converged, and plastic deformation occurs.

This method has some disadvantages:

• it is almost impossible to connect long details, because their size is limited to the design of the clamping device;
• a part of the billets in the sleeve sleeve is deformed;
• it is difficult to extract the parts from the clamps.

Point weld

This method is used to weld the aluminum blanks of therapy. Special punches are used. The location of the pressed punch is called a welded point. Welded points are located along the connection line through some interval.

The advantage of this method is the lack of the need to preliminarize parts and low metal deformations in the United locations. This is the most common cold welding for aluminum. It can be done without clamping or on fixed details.

Suture welding

For the formation of a continuous seam with this method of welding, rollers can be used, between which connected billets or ring-shaped punches.

Welding can be performed either by one rotating roller, which presses aluminum parts to the support, or two rotating rollers, which clamp parts each other.

Depending on the cross section of parts, the roller seam can be made on the milling or manual tabletop.

With this method, the connection is obtained without flaming, but its disadvantage is the thinning of the cross section of the parts in the silence, which leads to the inflection and torsion of the billets in this place.

It is possible to reduce such a lack by increasing the diameter of the working surface of the rollers. Or the use of this method is better to avoid.

Aluminum welding technology

Welding shift - method of cold welding of aluminum. Performed by squeezing with tangential displacement. As a result of this process, all oxide films are being made, forming the bridges of the compound. This method is applied in industrial environments for connecting the wiring and trolleybus wires, radio climbers, cable shells, different frameworks for household appliances. Excellent result It turns out when welding aluminum with its alloys (subject to the purity of the surfaces of the blanks). In the case of the smallest contamination, it is almost impossible to achieve a good quality compound.

To obtain good quality Connections, sedimentary pressure is applied so that the metal can freely flow from both sides from the welding location. Only the execution of such a condition will allow to achieve the correct displacement of parts relative to each other.

Seam on aluminum sheets can be performed:

• straightforward;
• circular;
• continuous (any length).

Application and features

Before work, clean the surface with steel rotating brushes. Aluminum welding can be done with various metal. Quite often applies welding of aluminum pipes. In the laboratory conditions, an attempt was a welding with aluminum and steel stamps.

Behind cold welding there is a great future. Despite the fact that new methods of using high frequency current are being developed, such installations are obtained sufficiently expensive, and their efficiency will also remain at a rather low level.

Welding and soldering can be performed under the influence of induced currents. When welding a constant current of aluminum, you can act as follows: To the solution of alkali, omit two rods, then skip d.C.. As a result, there will be a quick warming up of a minus rod. Now you should remove the rods and make a precipitate.

This method is used in laboratories. In industry, he did not find his place.

When cold welding is made for aluminum, there are no external heating of parts. This allows you to connect to the insulation of the electric pipe, carry out work in a flammable zone, close the holes in the container, which can not be heated. In addition, there is a compound of aluminum with steel. When using cold welding on aluminum, the metal waste can be reduced almost 10 times. Applying aluminum welding equipment, join copper and titanium, as well as other metals and alloys with plasticity. For welding aluminum, fluxes are not always needed.

Point welding can be connected sheet metal Thick up to 15 mm.

The shock method connects the rods with a cross section of up to 30 mm and the wire of the same diameter. Cold welding for aluminum high temperature can connect strips from copper with a cross section of 100 x 10 mm very durable seam.

Suture welding on details from sheet material It turns out hermetic seams absolutely any length

Aluminum welding with a cold method is intended for stationary conditions. Equipment may have a precipitation mechanism, hydraulic engineering, parts clamping mechanism.

Cold welding for household needs includes fillers, sulfurous additives. The polymer composition has a gluing property that appears with a small heating. It can be obtained by kneading a piece of substance in the palms for several minutes. Then the mass can be applied to the location of the parts.

This is used when performing small repairs household appliances, plumbing, risers, radiators, windows, silencers, fuel tanks, etc.

Mass after grappling is capable of taking if it is processed, any shape. Complete frost occurs after 1-8 hour. Details after that can be painted.

Cold welding for aluminum reviews of people repeatedly used it, received the most positive. After analyzing them, it can be concluded that the durability and quality of the compound, as a rule, are completely dependent on the selected adhesive composition and the correctness of the technology.

Cold aluminum welding in St. Petersburg is carried out both in specialized car operators and on their own at home. Packaging material costs from 38-40 rubles.

Best Cold Welding for Aluminum

It is specially intended for the repair of aggregates and from aluminum, silumin and dural.

The fast-dried cold welding of "polyrem aluminum", which was specially developed for better adhesion to aluminum and its alloys, makes it possible to conduct high-quality and reliable repair of aluminum parts, without the use of the welding machine.

Applying this cold welding, you can efficiently and quickly repaired:

• aluminum car wings;
• car radiators;
• pipelines made of aluminum or alloys;
• cylinder heads of auto;
• body panels and other car details.

Cold welding for aluminum, the price of which depends on the package and ranges from 40 rubles, specifically contains a filler that provides the composition of reinforced adhesion precisely to aluminum and its alloys.

Now you do not need to mess with welding apparatus - You can simply take cold welding for aluminum, mix the composition with your hands and proceed to repair.

It is important to consider that aluminum absolutely no adhesion is absolutely not possessing, for an oxide film prevents this (necessary adhesion) on the metal surface of the metal.

Nowadays there is a special glue for aluminum structures, which destroys this film increasing adhesion (adhesion).

That is, you need to buy glue in the instructions of which is the word "aluminum9.

The best in this area is considered to be glue on epoxy, or on a polyurethane basis.

There are single-component glue for aluminum, there are two-component.

There are for external and for internal work, there are universal (that is, outdoor and internal work).

If it was interested in the brand of glue for aluminum, then here is not a bad option "ottokol M501".

Pluses this glue set, works and aluminum including anodized aluminum.

You can work in and outside the premises (universal).

Virtually odorless.

Aluminum gluing process is alternative way welding. But in contrast to the second variant, the gluing process is relatively simple.

But it is necessary to take into account the fact that only special glue is suitable for these purposes. As part of such glue, alkali and acid must be present, as they contribute to the splitting of oxide "film9 and increases the stickiness property.

The photo presents the variants of such adhesives that can be used for these purposes.

We will analyze the gluing of aluminum using the glue of cold welding Mastix.

At the first stage, using emery paper, we remove rust from metal, after which they degrease the surface using acetone.

Apply glue to the glued surface. Connecting the surfaces, fix for 15 minutes, tightly shrinking them.

Aluminum glued only with adhesives with a base of epichlorohydrine with phenol polycondensation products. Or it's easier to say epoxy resins. These are the only glue that I can glue such materials as aluminum. And at the same time, the aluminum surface is processed or not, I will say more aluminum to prepare for gluing it is impossible since it is oxidized instantly. Therefore, do not waste strength and do not make unnecessary work.

Adhesive for aluminum

Why is aluminum badly glue?

Aluminum is a magnificent metal. Doors, windows, facade systems Aluminum is distinguished by ease, strength and resistance to exposure external environment. One "But": welding of aluminum structures - difficult processAvailable only by professionals.

Therefore, almost the only one affordable for " common use»A gluing remains by connecting aluminum surfaces. It would seem that it could be easier? However, and here aluminum shows its tricky nest.

The fact is that in the usual state of aluminum is covered with solid oxide film, which has very low adhesion. If it is not destroyed before gluing it, any connection will be fragile and short-lived. Simple mechanical processing of the detail is ineffective: the surface of the surface is quickly oxidized again.

Comparatively good results can be achieved only by pre-prepared the surface of aluminum parts by acids, alkalis, or special compositions, usually on a polyurethane or epoxy basis. Therefore, most of the adhesive compounds produced for aluminum include these chemical compounds.

Adhesive for aluminum

The most common is a two-component glue for aluminum. As it is clear from the title, it consists of two components: epoxy or acrylic mass, and hardener. Before use, these components are mixed.

The good quality of the adhesive connection is achieved if the surface of the surface of aluminum parts is deguted, or to cover with a special primer, however, in the latter case it is necessary to monitor the primer and glue, mixing, do not give an unexpected chemical reaction. A single-component glue for aluminum is widespread, in the peoples called "Cold Welding".

It is very convenient in use, but formed to them adhesive connection Personally, therefore, cold welding is usually used for sealing slots and holes.

It should also be particularly important about the compound of aluminum with the surfaces of other types (for example, with a stone). Due to the highly large difference in thermal expansion, the adhesive connection of such surfaces will be fragile. Therefore, in such cases, it is recommended to use a mechanical connection or connection using an elastic adhesive tape.

And let some say that the "good" glue for aluminum does not exist, with a certain effort and compliance with the instructions, you can achieve a qualitative result in the gluing of this capricious metal.

How and how to glue aluminum with aluminum. Types of cold welding

Aluminum and its alloys - one of the most common in modern world Metals. It has a lot of advantages, thanks to which it has gained popularity, but its use is marked by a number of shortcomings. In particular, the stumbling block becomes fastener.

This metal is poorly withstanding ordinary bolt connections because of its softness. It can be welded with argon. But it requires complex equipment and a qualified specialist who may not be at hand.

Therefore, in many cases, especially when there are no special requirements for the tensile strength, cold welding for aluminum comes to the connection.

What is it or welding

In fact, the term "cold welding" is called two different ways of connecting aluminum parts with each other.

The first, often used in the factory conditions, is based on the principle of diffusion, that is, the interpenetration of molecules of two solids In contact with each other. Diffusion is in principle characteristic of many metals, with some (aluminum, copper and some others) the process is faster than others.

This process is initiated by pressure. Under the action of the pressure of a molecule of two different aluminum parts, as it were, "mixed" with each other, new intermolecular bonds are formed, and a sufficiently durable seam is formed.

Another way to connect aluminum parts is a gluing. It is the glue for aluminum most often associated with most people with the concept of cold welding.

Mainly use various two-component compositions, the basis of which is epoxy resin. An additional component that ensures strength and grasp with metals is a fine steel powder, which is added to the epoxy base immediately before use.

Such adhesives can be produced in various aggregate states - both in a liquid or semi-liquid form, close to the gel or actually resin, and in the form of mastic - plasticine mass, from which rectangular or cylindrical bars are formed.

Each bar consists of two not mixed with each other. Mixing, which activates the adhesive properties of mastic, occurs in the fingers of the person immediately before applying.

Advantages and disadvantages of welding by deformation

The first method is cold welding under pressure - more often used when stamping parts at the factory.

Its main advantage is that the seam is formed from the same material as the details, it reduces the conveyor production and allows you to form compounds, by strength approaching cast parts.

Cool welding of aluminum under pressure, one can say high-temperature. It allows items to withstand the same level of heating as pure aluminum.

Advantages of welding by deformation:

• withstands large temperature differences;
• withstands great pressure (but no more than the metal itself can withstand);
• manifests persistence in aggressive environments;
• does not highlight harmful substances Environment.

The main disadvantage is only the need to use special equipment for such welding.

There are three main ways of such welding:

In the first case, two parts are connected in the press of the joint-B-joint and are strongly squeezed along the longitudinal axis.

In this way, you can weld elements with the local area of \u200b\u200bdocking (small size). It is necessary to take into account the process of "loss" of material after compression: so, when welding in such a way of two segments of aluminum reinforcement them total length It turns out to be 5-7% less than the total length separately.

The suture method be bonded between two parts with a large seam length, for example, two sides of one sheet, forming a pipe. They are connected to the mustache and placed under the pressure roller. Rounding, the roller squeezes aluminum sheets and presses them to the support shoe, pushing each other. Thus, uniform seam is formed.

The disadvantage of this technology is that this seam itself is a weak place in the design. Therefore, where you need to withstand high loadsThe sovn-point method is used, in which the roller is not smooth, but processed. Treads are working protrusions that provide localized pressure, and the seam looks not like a line, but as a uniform chain of points. He is stronger than the "smooth" seam.

Finally, the actual point method - on two connected sheets of sheet or aluminum plates, a power is carried out at several local points with super-harden objects - punches.

When they indulge them in aluminum and subsequent extraction, a welded point is formed. With the correct calculation of the geometry of these points and the magnitude of the deforming effect, it is possible to achieve a very high quality of the compound with minimal metal losses.

Please note: during butt welding antioxidant treatment, that is, the abrasion of the surface oxidized layer, occurs simultaneously with the welding process, in all the others it is necessary to pre-clean the surface of the welded parts from oxides.

Advantages and disadvantages of welding with glue

The main advantage of any adhesive compositions is the ease of use in everyday life, for personal needs, including in the production of work with tightness requirements. You can choose an adhesive composition with special additives for high-temperature welding. This method of connecting aluminum parts is very simple and cheap.

How to glue aluminum with aluminum? If you use a two-component mastic bar, simply cut the required amount from it and get drunk in your fingers until the masses are mixed and softened.

Declaring surfaces that are going to glue, acetone or other solvent, wipe dry and apply the composition. Plastic mass will take any shape and fill any hole, so it can be used for sealing cracks in aluminum parts, installation of sanitary elements and other needs in virtually any sphere.

If you use the composition with the liquid base, then following the instructions, simply mix the metal powder with an epoxy mass until the plastic mass is obtained, and proceed in the method described above.

Employment of such welding - ease of use and low prices On the compositions, then the shortcomings are much more.

Cooked trunk with mastic or glue details can not be exposed to large loads, especially on the break. Glue provides tightness, but is not capable of withstanding strong pressure, although there are separate compounds that form a very strong connection. The prices of them are naturally higher.

High temperatures, and especially temperature differences can also carry not every composition. It should be very careful to the processing of glued parts, especially for degreasing - any fats reduce adhesion properties of glue.

The time of complete solidification of glue is usually 2 - 2.5 hours. It is necessary to further prepare exactly so much glue, but they are going to use, otherwise (it is especially characteristic of liquid adhesives), it will find it tightly, and the dishes in which he was prepared, will have to be thrown. In addition, in order to avoid poisoning, pairs are recommended during work to use the respirator.

Aluminum glue - Answers to important questions

Aluminum is a metal, characterized by ease, strength and resistance to external environmental impact. This metal has its drawback - it does not have adhesion properties.

Therefore, it is necessary or welded, or glue. Since only professionals can perform welding, aluminum glue is an excellent household option. But for this metal, only special glue will fit.

Any glue, intended for aluminum, must contain in its composition of the pickens and acids that destroy its oxide film and increase adhesion, providing a solid connection.

What and how to glue aluminum with aluminum

With development modern technologies Firmly glue aluminum parts with each other with a cold method.

To do this, you will need:

• Cold welding Mastix glue;
• Sandpaper;
• Alcohol, acetone or any other degreasing agent.

To glue aluminum Such glue, you need:

• Clean the surfaces to connect from rust and dirt sandpaper;
• Degrease alcohol or acetone;
• Wait until the surface is dry;
• Cut off the desired amount of the rod and mix well two components with your fingers so as to obtain a homogeneous mass in the form of plasticine. Coloring should be uniform;
• Adhesive mixture on both aluminum surfaces that will be connected;
• Tightly press and fix them for 15 minutes until the glue will open.

What and what else can aluminum can be glued

Two-component aluminum glue on epoxy basis has high adhesionic and heat-resistant properties.

With it, aluminum can be glued with other materials with various thermal expansion: stone, porcelain, wood or plastic.

To glue an aluminum surface with other metals and materials, it is necessary to prepare:

• Epoxy heat-resistant glue gun epoxy metal;
• Sandpaper;
• Tassel;
• Means for degreasing the glued surface (alcohol or acetone).

After that, you can proceed to work:

• Bonded surfaces to clean the coarse-grain emery paperto remove dirt and rust;
• Degrease the details of acetone or alcohol;
• Dry;
• Squeeze into a separate container the contents of two glue syringes (epoxy mass and hardener) in proportion 1: 1;
• Mix well epoxy and hardener with each other with brushes;
• Apply glue with a tassel on both glued aluminum surfaces;
• Connect the details and close them tight for a few seconds;
• Excess glue immediately wipe the cloth;
• Wait 30 minutes while glue mix hardens.

Although many do not recognize the efficiency of using glue for aluminum, correctly selecting the goods and performing glued works clearly according to the instructions, it can be achieved as much as possible compound.

Moreover, such a type of connection can be combined with mechanical fastening.

What to glue alluminous?

For gluing de waves from aluminum, it is necessary to use special adhesives, which in their composition contain special substances that do not give on the glued surface to form films from oxides, because it is the problem in the strength of the glued surface.

Look at the glue so that it was precisely an appointment - for aluminum and never use universal glue. One of the types of glue is Mastix

Accordingly, before gluing, treat the surface with sandpaper and then wipe the solvent and do not pull the time, it is necessary to glue at once, since the film is formed quickly and the quality will not be very.

Aluminum can be glued with a two-component glue made based on epoxy resin. In cases where it is necessary to glue not pure aluminum, but a certain alloy with an aluminum content, it is better to prefer glue containing methyl acrylate.

Before entering into gluing aluminum parts, you need to clean them from dirt and fat. This can be done using a rigid brush or rash. Then it is necessary to clean the details of the sandpaper (best fine-grained) and only then apply glue (thin stripe or point), after which it is tightly pressing the surface to each other.

Therefore, it is necessary or welded, or glue. Since only professionals can perform welding, aluminum glue is an excellent household option. But for this metal, only special glue will fit.

With it, aluminum can be glued with other materials with various thermal expansion: stone, porcelain, wood or plastic.

To glue an aluminum surface with other metals and materials, it is necessary to prepare:

• Epoxy heat-resistant glue gun epoxy metal;
• Sandpaper;
• Tassel;
• Means for degreasing the glued surface (alcohol or acetone).

After that, you can proceed to work:

1. Bonded surfaces to clean up coarse sandpaper to remove dirt and rust;
2. Degrease the details of acetone or alcohol;
3. Dry;
4. Squeeze into a separate container the contents of two glue syringes (epoxy mass and hardener) in proportion 1: 1;
5. Mix well epoxy and hardener with each other with brushes;
6. Apply glue with a tassel on both glued aluminum surfaces;
7. Connect the details and close them tight for a few seconds;
8. Excess glue immediately wipe the cloth;
9. Wait 30 minutes while the adhesive mixture hardens.

Although many do not recognize the efficiency of using glue for aluminum, correctly selecting the goods and performing glued works clearly according to the instructions, it can be achieved as much as possible compound.

Moreover, such a type of connection can be combined with mechanical fastening.
