Car painting with powder paint. Powder coating of car and motorcycle wheels Powder coating of cars

Having bought a brand new car, its owner expects that its shining appearance will remain for a long time ... In practice, unfortunately, everything turns out to be not so rosy. Constantly exposed to a number of influences during operation, the body elements lose their appearance and need to be restored. In this case, powder painting of bumper and door moldings, mufflers, calipers and other important components that 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 her, the service life of the painted element will be significantly extended, and its outer will be at its best!

What is powder painting of auto parts? Why is it needed?

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

Also worth mentioning are the chemicals used to remove snow and ice from roads in winter period time. They also do their bit by having a devastating effect on metal. Powder painting of a car muffler, its nozzle, calipers and other elements helps to solve all these problems. Thanks to her, they:

• get 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, by spending money on powder painting, you will save much more on repair and replacement.

Powder painting of a car is a modern technology that involves the application of paint and varnish and polymer coatings to various elements of the car (body, fenders, wheels, bumpers).

The use of powder paint improves the protective properties and is safe, waste-free and of 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 painted parts, 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 to paint garden and office furniture, metal tiles and others roofing materials, furniture fittings, instrument brushes, refrigeration equipment, shelving, sports equipment, etc.

Features of powder coating

Painting surfaces powder paint characterized by the following features:

• No need to carry out additional operations (applying an additional layer, adjusting the viscosity, tinting, dissolving, diluting);
• One layer application;
• 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 painting reach 50% -60%, and when using powder paint - only 1-2%.

Powder paint composition

The powder paint contains the following components:

• Polymer;
• Color pigment;
• Filler;
• Special additives that create structure and regulate flow.

  

  

  

  The composition of the equipment and the type of paint used

  Powder paint should be applied in a spray booth equipped with special equipment (polymerization oven, recuperation system, paint sprayers). Of ordinary equipment spray booth must be equipped with an air supply and filtration system. The different polymer used forms the basis for dividing paint into two categories:

  • Thermoplastic;
  • Thermosetting.

  Thermoplastic paints, fusion-free when heated, create rather fragile coatings. Therefore, their thermoset analogs, characterized not only by fusion of particles, but also by a 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 painting of a car with powder requires preparatory operations, which includes the production of the following work:

  • Mechanical treatment (cleaning) of oxides and rust on metal elements;
  • Dust removal and degreasing of painted surfaces;
  • Application of a layer of chromate or phosphate to the 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 paint

  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 opportunity for self-coloring paint, compensated by a huge number of colors and shades directly from manufacturers;
  • Difficulties in coating surfaces with low thermal resistance;
  • Limiting the minimum thickness of the applied layer (35 microns).

  Technological sequence of operations

  Let's consider the main stages of powder coating on various elements of the car.

  Surface preparation

  Powder painting should be done on a carefully prepared surface, free of 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 old coating layer, but also to harden the upper layer of the treated surface.

  

Car decoration and styling is one of the moments of confirming the status and demonstrating the taste of the car owner. This direction has its own 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 main requirements: speed of execution, reliability and durability in operation, as well as an optimal ratio of quality to cost.

All the 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 devices that need to be recouped over several years of operation.

ChipsAway

This new technology was developed in the UK, so it allows you to quickly repaint a car or get rid of minor damage to the body with the usual British accuracy. More than 1,500 large services have been opened in Europe and America, providing this service, while in the domestic market this technique is only gaining momentum.

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

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

The main advantages of ChipsAway:

• The technology makes it possible to dispense with the minimum area of \u200b\u200bsurface preparation. With the classic methods, the entire part is sanded, while with ChipsAway, the scratch or dent and the minimum area around it are sanded directly. This preserves the original coating as much as possible.
• Painting can be carried out without disassembling a complete part in a complete assembly, which allows you to maintain all factory settings and prevent parts replacement or damage during the process.
• Exceptional shade matching. The technique has in its arsenal a spectrum of 58 thousand shades of the entire palette, not excluding the “metallic” color and the difficult-to-select options “chameleon” and “mother of pearl”. A separate staff of colorists is constantly working on adding and finalizing the palette for ChipsAway.
• Car painting speed for this modern technology is several hours, and in the case of a large cultivated area - a little less than a day, after which the car can be used as usual.
• The composition of the components in the coating solution consists of more environmentally friendly substances. The ChipsAway chemical formula, thanks to the new complex, can be combined with any type of coating (factory or repair). No environmentally harmful fumes are generated during the painting process.

Pigmented pastes are held securely with chemical additives that provide resistance to peeling, flexible filling during application and high adhesion.

EcoDryScrubber

EcoDryScrubber technology was developed, tested and patented by the German company Dürr based in Stuttgart. This technique is used by concerns and large 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.

The application of paintwork to the body is the most energy-intensive moment in the production of cars, therefore EcoDryScrubber has taken into account all possible prospects in saving electricity during painting.

The main advantages of the EcoDryScrubber system:

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

Saving paint material during automatic painting with EcoDryScrubber it reaches 85%. In addition, the system reduces the squaring of the painting booth 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 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 painting is a very reliable and modern method.

Advantages of powder coating a car:

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

The principle of the scheme is that a continuous static charge is applied to the car in the paint booth, 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 wrap is an affordable budget method to make your car stand out on the road by combining interesting design and the reliability of the coating. The skin can be different colors, but it can also be transparent - this meets the requirements of those people who do not want to change the chosen design.

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

Advantages of vinyl wrap:

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

Self-adhesive vinyl is completely weightless, it makes it easier to wash the car, and after removing it leaves no marks 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. A drawing or inscription can be applied to it, if desired, to emphasize the individuality of the product.

Metallic painting

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

The technology allows the car to be painted 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.

Metallic paint benefits:

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

Of the shortcomings, one can single out the mandatory thoroughness of the preparation and the duration of the process, since it occurs in three main stages. Strict adherence to the technology of time-consuming procedures is the main guarantee of success.

Paramagnetic paint

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

The essence of the method is 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 is changed, 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 completely change the color. 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, therefore, most likely, it will not work en masse. 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 a tint effect at the right time.

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

This technology is used in the case when it is necessary to replace one or more parts, but to give full compliance they need a special coating.

Advantages 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 no sanding is required after each layer is applied. The layers are applied to an untreated coating that is not completely dry. Under such conditions, it is very important to exclude any specks and flying debris from the spray booth area, since it will immediately settle on the wet layer and appear as large errors as a result.

A new trend in painting is moving away from the use of standard paints in the auto industry to alternative materials that will ensure the durability and safety of the car.

To apply liquid rubber fundamentally new equipment is needed, but its cost is not high, therefore, innovative development does not differ in high cost.

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

Advantages of using "liquid rubber":

• inertia and stability forgiving atmospheric phenomena;
• resistance to chips and scratches;
• low cost;
• no need to disassemble the vehicle and, as a result, savings on reinforcement 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 fragility and reducing splinter formation. polymeric 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 car manufacturers continue to present revolutionary technologies that can significantly expand the functionality and embodiment of car painting.

One of the most effective techniquesPowder coating of a car is a good quality polymer coating with outstanding protective and performance characteristics. Now we would like to tell you about what powder formulations are made of and how the coloring process goes.

A few words about powder paint

The principle of painting is based on the use of 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.
... A coloring pigment that determines the final color of the product.
... A special filler required to strengthen the polymer film.
... Various additives that create the effect of structure and regulate the process of paint spreading.

Features of coloring

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

Powder coating technology consists in the ability of magnetized paint granules to adhere and adhere to 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 to melt the powder composition and form 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 separate part, after which the product is polymerized in the oven. When talking about the commercial and industrial use of the powder method, the 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 the purpose of serial production of small batches or single use. Usually they consist of a chamber and a unit itself, together with filters necessary to clean the air from particles of the powder composition.

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

Painting principle

Each painting booth certainly includes two systems: recovery of the dye 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, it 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 machine components.
