Painting a car with powder paint. Powder coating of car and motorcycle rims Powder coating of cars

Having bought a brand new car, its owner expects that its shining appearance will last for a long time... In practice, unfortunately, everything turns out to be not so rosy. Constantly subjected to a number of influences during operation, body elements lose their appearance and need to be restored. In this case, powder coating of bumper and door moldings, mufflers, calipers and other important components, which also determine the aesthetic characteristics of the car, comes to the rescue.

It has a number of advantages and allows not only to improve the appearance of the vehicle, but also to create a polymer coating that will last for a long time. Thanks to it, the service life of the painted element will be significantly extended, and its external appearance will be at its best!

What is powder coating of auto parts? Why is she needed?

Powder coating- This special technology applying powder paints to various elements of the car body, which allows you to get a polymer coating. The latter is characterized by excellent aesthetic and strength characteristics and allows you to extend the service life of the processed elements. This is very true when it comes to the car body. During the ride, its parts are subjected to impact, small pebbles hit them, which leads to chips and scratches. Frequent contact with moisture is the cause of the development of metal corrosion processes, therefore, over time, expensive restoration (or even replacement) of the element may be required.

Worth mentioning are the chemical reagents that are used to remove snow and ice on roads in winter period time. They also do their bit, having a devastating effect on the metal. Powder coating of the car muffler, its nozzles, calipers and other elements helps to solve all these problems. Thanks to her, they:

• receive effective protection from exposure to moisture, therefore, corrosion processes do not develop on them;
• high level of protection against mechanical and shock loads;
• a decent level of protection against the destructive effects of chemicals.

Thus, having spent on powder painting, you will save much more on repairs and replacements.

Powder coating of a car is a modern technology that provides for the application of paint and varnish and polymer coatings on various elements of a car (body, fenders, wheels, bumpers).

The use of powder paint improves the protective properties and is safe, non-waste and high quality. For painting, high-polymer powders are used, applied to the surface in powder spraying chambers under the action of an electrostatic field.

After the paint settles on the surface of the parts to be painted, they must be heated in special ovens.

Polymerization is carried out at a temperature of 160°C to 200°C, sufficient to form a strong and thin polymer layer.

Powder coating is successfully used for applying paintwork on garden and office furniture, metal tiles and others. roofing materials, furniture fittings, instrument brushes, refrigeration equipment, racks, sports equipment, etc.

Features of powder coating

Surface painting powder paint characterized by the following features:

• No need to carry out additional operations (applying an additional layer, adjusting the viscosity, tinting, dissolving, diluting);
• Application of one layer;
• Economic benefit.

The economic benefit when using powder paint consists of several components: savings on materials (by reducing paint losses and using a recovery system), human and time resources. By the way, losses with the traditional method of staining reach 50% -60%, and when using powder paint - only 1-2%.

The composition of powder paint

The composition of powder paint includes the following components:

• Polymer;
• color pigment;
• Filler;
• Special additives that create structure and regulate spreading.

  The application of powder paint should be carried out in a spray booth equipped with special equipment (polymerization oven, recovery system, paint sprayers). From conventional equipment spray booth must be equipped with an air supply and filtration system. The different polymer used underlies the division of paint into two categories:

  • thermoplastic;
  • Thermoset.

  Thermoplastic paints, fused without chemical transformation when heated, create rather fragile coatings. Therefore, their thermoset counterparts, characterized not only by the fusion of particles, but also by the chemical reaction between them, have found wider application. The result of using thermosetting paint is durable and resistant to various influences(physical or chemical) coating.

  The main stages of preliminary preparation of the coating

  High-quality powder painting of a car requires preparatory operations, which include the following works:

  • Mechanical treatment (cleaning) of oxides and rust on metal elements;
  • Removal of dust and degreasing of painted surfaces;
  • Applying a layer of chromate or phosphate to a degreased surface, which increases the adhesion force between the surface and the powder.

  Advantages of powder paint

  Powder coating is characterized by a reliable, durable coating, which can be obtained due to the numerous advantages of the paint used in this method:

  
  

  Disadvantages of Powder Coating

  Among the disadvantages of powder paint are the following:

  • The possibility of using this method only on complex expensive equipment that requires special training of maintenance personnel;
  • Lack of possibility for self-coloring of paint, compensated by a huge number of colors and shades directly from manufacturers;
  • Difficulties in coating surfaces characterized by low thermal resistance;
  • Limitation of the minimum thickness of the applied layer (35 microns).

  Technological sequence of operations

  Consider the main stages of applying powder coating to various elements of the car.

  Surface preparation

  Powder coating should be carried out on a carefully prepared surface, on which there are no oxides and chips. For these purposes, you can use the method of sandblasting or shot blasting, which allows you to completely remove the old coating. Next, the surface is degreased with alcohol-containing liquids or detergents. Degreasing ensures high adhesion of the powder coating, and sandblasting allows you to remove not only the layer of the old coating, but also to harden the top layer of the treated surface.

  

Decorating and styling cars is one of the moments of confirming the status and demonstrating the taste of the car owner. In this direction, there are trends, modern technologies and even fashion. As a rule, all new developments in this direction pursue not only elegance and beauty. appearance auto. They combine the basic requirements: speed of execution, reliability and durability in operation, as well as the optimal ratio of quality to cost.

All technologies that have appeared recently are more expensive than those that have been used for a long period. This is due to the need to purchase new materials and apparatus, which must be recouped over several years of operation.

ChipsAway

This new technology was developed in the UK, so it allows you to quickly repaint the car or get rid of minor damage to the body with the accuracy inherent in the British. In Europe and America, more than 1.5 thousand large services providing this service are open, while in the domestic market this technique is only gaining momentum.

The main difference about the classical methods is that when painting, most often the composition of the chemical coating contains a substance hazardous to health - isocyanide. It is harmful to the personnel who apply the composition, but it was not possible to do without it before, because it was this reagent that made the coating harden quickly.

ChipsAway Technology was able to find an alternative substance that accelerates evaporation and solidification, but does not belong to the group of isoamyl phenols.

The main advantages of ChipsAway:

• The technology makes it possible to get by with a minimum area of ​​surface preparation. With classical methods, the entire part is subjected to grinding, while with ChipsAway, the place of a scratch or dent and the minimum area around are ground directly. This preserves the factory original coating as much as possible.
• Painting can be carried out without dismantling the complete assembly, which allows you to save all factory settings and prevent replacement of parts or damage caused in the process.
• Exceptional color accuracy. The technique has in its arsenal a range of 58 thousand shades of the entire palette, not excluding the color "metallic" and the difficult-to-select options "chameleon" and "mother-of-pearl". A separate staff of colorists is constantly working on adding and refining the palette for ChipsAway.
• Auto coloring speed for this modern technology is a few hours, and in the case of a large treated area - a little less than a day, after which the car can be operated in normal mode.
• The composition of the components in the coating solution consists of more environmentally friendly substances. The chemical formula of ChipsAway thanks to the new complex is combined with any type of coatings (factory or repair). The painting process does not produce environmentally harmful fumes.

Pigmented pastes are securely fixed with chemical additives that provide peel resistance, plastic filling upon application and high adhesiveness.

EcoDryScrubber

The EcoDryScrubber technology was developed, tested and patented by the German company Dürr, based in Stuttgart. This technique is used by corporations and major vehicle manufacturers, since it is very profitable in economic terms: the cost of painting costs is reduced by 30-60%, which also affects the total cost of the car.

Applying body paint is the most energy-consuming moment in car production, so EcoDryScrubber took into account all possible prospects for saving electricity during painting.

The main advantages of the EcoDryScrubber system:

• air recirculation in the staining chamber, which eliminates the need for a powerful air cleaning system;
• dry filtration of contaminants present in process air;
• replacing hydrofiltration with recirculation saves a huge amount of water;
• significant reduction in pollutant emissions.

Saving paintwork material reaches 85% during automatic painting with the EcoDryScrubber system. In addition, the system allows you to reduce the quadrature of the painting chamber by 35%.

The technology minimizes carbon dioxide emissions, which allows us to call it not only one of the most profitable, but also advanced in terms of ecology.

Powder coating

This method combines many of the advantages of the previously available methods. The only caveat is that it will not work to use this technique in a car repair shop or service station. But for manufacturers, powder coating is a very reliable and modern method.

Benefits of powder coating your car:

• polymer coating is operated for a long time;
• symbiosis of decorative and protective functions;
• reliable protection against corrosion and exposure to aggressive liquids;
• improving the electrical insulation characteristics of the vehicle.

The principle of the circuit is that in the painting booth a continuous static charge is applied to the car, and the opposite pole is applied to the machine with powder paint. Due to mutual attraction, finely dispersed paint particles settle on the surface in an even layer, forming a uniform tone on the body.

Then the machine is placed in a special oven, where, under the influence high temperatures the powder is polymerized and baked.

Vinyl wrap

Vinyl wrapping is an affordable budget method to highlight your car on the road by combining interesting design and coverage reliability. The cover can be different colors, but can also be transparent - this satisfies the requirements of those people who do not want to change the chosen design.

Vinyl coating can be used both on the entire surface of the car, and selectively on those areas that need special protection.

Benefits of vinyl upholstery:

• protection against small scratches, abrasions, traces of stones or gravel;
• covering not only the body, but also optics, as well as mirrors;
• application speed.

Self-adhesive vinyl film is completely weightless, it makes it easier to wash the car, and after removal it leaves no traces at all. The term of its use is not limited, which allows you to get a guarantee of up to 7 years.

The film can be carbon, matte, glossy or natural. On it, if desired, they can apply a drawing or an inscription to emphasize the individuality of the product.

Metallic painting

This method requires high qualification of the performer and automation of most stages. The fact is that the metallic highlights all the flaws and flaws that were not visible before painting.

The technology allows you to paint the car in bright colors with a metallic sheen. In order to achieve this result, paint manufacturers add the smallest particles of different metals to the composition, which will determine the main physical properties of the coating.

Advantages of metallic painting:

• excellent protection against corrosion;
• easy car wash
• ease of polishing scratches with varnish in case of minor damage or abrasions.

Among the shortcomings, one can single out the mandatory thoroughness of the preparation and the duration of the process, since it takes place in three main stages. Strict adherence to the technology of labor-intensive procedures is the main key to success.

Paramagnetic paint

This innovative technology car painting has already been patented and is only preparing to enter the serial market.

The essence of the method lies in the fact that before painting a special polymer is applied to the body, consisting of paramagnetic tiny particles of iron oxide. With the help of an electric current, the distance separating such particles changes, due to which they reflect different waves of the spectrum. Outwardly, this manifests itself as a change in the color of the car.

It takes about 1.5 seconds to complete the color change. With this method, you can give any color to your car, depending on your mood. It is assumed that the cost of such painting will be quite high, so most likely it will not be possible to use it in large quantities. But for individual consumers, it can provide an excellent opportunity to satisfy the craving for frequent changes.

The technique has already been used for anti-reflective coatings in aviation, and some auto companies have used it to provide the effect of tinting at the right time.

So far, the issue of how to register the color of a car with paramagnetic paint in the data sheet has not been resolved, but at the moment this issue is being resolved.

This technology is used when one or more parts need to be replaced, but a special coating is needed to give them full compliance.

Benefits of the wet-on-wet method:

• low cost;
• execution speed;
• the need for a single sanding at the time of pre-paint preparation.

The main difference of this technique is that after applying each layer it is not necessary to carry out grinding. Layers are applied to the raw coating, which is not completely dry. Under such conditions, it is very important to exclude any specks and flying debris from the area of ​​the spray booth, since it will immediately settle on the wet layer and manifest itself as large errors as a result.

The new paint trend is moving away from standard automotive paints to alternative materials that will ensure the durability and safety of your vehicle.

For application liquid rubber fundamentally new equipment is needed, but its cost is not high, so innovative development is not expensive.

6-12 layers of a liquid composition are applied to the surface of the body, which quickly hardens. The speed of such a manipulation is surprisingly fast: it will take from 30 to 60 minutes to completely process a sedan.

Advantages of using "liquid rubber":

• inertness and stability against atmospheric phenomena;
• resistance to chips and scratches;
• low cost;
• no need to dismantle the vehicle and, as a result, saving on reinforcing work.

The declared service life of such "liquid rubber" is 12-17 years. Preliminary tests have shown that rubber improves vehicle performance during crash tests by reducing body brittleness and curbing splinters. polymer materials upon collision.

The auto industry does not stand still. Over the past decade, the approach to painting has changed, and at the moment, well-known automakers continue to introduce revolutionary technologies that can significantly expand the functionality and embodiment of car painting.

One of the most effective methods, which allows you to achieve a high-quality polymer coating with outstanding protective and operational characteristics, is the powder coating of a car. Now we would like to tell you about what powder compositions consist of and how the staining process goes.

A few words about powder coating

The principle of painting is to use modern high-polymer powder compositions, which consist of small granules with a size of 10-100 micrometers. In addition to the polymer necessary to form a monolithic coating on the surface of the machine, the paint also includes other components, namely:
. Hardener.
. Coloring pigment that determines the final color of the product.
. Special filler required to strengthen the polymer film.
. Various additives that create the effect of structure and regulate the process of spreading paint.

Staining features

Although the car is enough overall product for painting a car, it, like any other metal part / device / mechanism, is painted in special chambers. Such chambers must be equipped with air filtration and supply systems, as well as paint sprayers and powder microparticle recovery systems.

Powder coating technology lies in the ability of magnetized paint granules to stick and hold onto various parts of the car and its body. The magnetized powder is sprayed and deposited in a thin layer on the surface of metal products, and then the car or its individual parts are transferred to a thermal oven for polymerization at a temperature of about 200 degrees Celsius for about 20 minutes. These conditions are necessary for the melting of the powder composition and the formation of a monolithic polymer film.

We have already talked a lot about the advantages and features of painting a car with powder paint in previous articles, so today we would like to shed light on such an interesting moment as a spray booth, which is perhaps the most important element of the whole process.

A few words about the camera

In this chamber, the powder composition is sprayed onto the entire car or its individual part, after which the product undergoes polymerization in an oven. In the commercial and industrial use of the powder method, spraying is usually carried out by means of electrostatic attraction. As for the use of powder paint at home, in this case any method can be used, including manual.

Now on the market you can find special chambers for powder coating for mass production of small batches or single use. Usually they consist of the chamber itself and the unit, along with the filters necessary to clean the air from the particles of the powder composition.

You can enter the machine into the dyeing chamber through a special opening, so during operation it will be completely inside the device. The remote control located behind the walls of the unit allows you to control the painting process.

The principle of painting

Each painting chamber necessarily includes two systems: the recovery of the coloring composition and air purification. The principle of operation is that the powder particles are magnetized, due to which they adhere tightly to the surface of the product due to the potential difference, thereby forming a uniform coating. After applying the powder, the product is heated to a temperature of about 200 degrees and the product is kept under such conditions for about 20-30 minutes. The camera can be used not only for painting the body, but also when working with discs, calipers, bumpers, mufflers and other car components.
