Moto rim, powder coated

Negative influence environment and poor quality of road surfaces adversely affect the condition of car wheel rims. To preserve and extend their performance to the maximum possible extent, as well as maintain an attractive appearance, we can recommend the method of painting them using powder paints. It is worth noting the high popularity and demand for powder coating technology for discs - more than 50% of discs are painted in this way.
Powder coating of discs is the application of a polymer coating with excellent protective properties, excellent adhesion and wear resistance at the highest level. In comparison with other types of coatings, it wins in each of the main parameters. When powder coating wheels, special equipment is used. with the help of which the coating is applied to the surface of the disk in the form of a polymer powder, without the use of various types of hardeners and solvents.

Below, in brief form, you can get acquainted with the procedure for painting wheels using the powder method, which takes place in several stages:

1. Thoroughly clean the surface of residues old paint using sandblasting or chemical cleaning.
2. If necessary, etching and applying a phosphating coating to improve the adhesion of paint to metal.

Powder painting of cars is the latest technology for applying polymer coatings and paints to the surface of cars, including the body, wheels and fenders. Powder painting is a special method of applying polymer coatings, thanks to which not only excellent decorative qualities are achieved, but also enhanced protective properties. This technology is environmentally friendly, waste-free and allows us to obtain high-quality polymer coatings.

Painting is carried out using high-polymer powders, which are applied to the surface of car parts intended for painting. The entire process is carried out in powder spray chambers. An electrostatic field is formed in these chambers, under the influence of which particles of polymer powder paint settle on the surface of the product.

After this, the car parts are heated in special ovens for polymerization. The melting point of the polymer is 160-200 °C. The part is kept in the oven for some time and then cools. In this case, a thin and durable polymer layer is formed on the surface. This painting technology can be used for glass or metal products, since these materials can withstand the specified temperature.

To date, about 15% of all painted products have been powder coated. And this figure is constantly increasing. This technology widely used not only in the automotive industry. Today powder painting of cars - This is far from the only area where this coloring method is used. Today, the most popular products are painted using the powder coating method. different types and purposes - office and garden furniture, roofing materials and metal tiles, instrument panels, furniture fittings, shelving, refrigerators, sports equipment and much more.

Powder paint is a special powder, finely ground polymer. Its particles have a size of about 10-100 microns.

As a painting method, powder painting has many advantages. The main advantage is that this technology does not require additional operations, such as dilution, dissolution, tinting, viscosity adjustment or coating with an additional layer. Powder painting is performed with one very thin layer of polymer coating.

Thus, powder coating is a cost-effective technology that can save not only on materials, but also on time and human resources. Additional efficiency is provided by the recovery system, which is used in spraying chambers. Those polymer particles that do not fall on the surface to be painted again enter the painting cycle. Thus, when powder coating cars and other products, it is possible to reduce dye losses to 1-2%. To make sure that powder painting is profitable, compare this indicator with the traditional painting method, where losses can reach 50-60%. The advantage of powder coating is obvious.

How is powder painting of cars carried out?

Powder painting of cars- This is a technology that uses special equipment - polymerization ovens and spray chambers. The equipment complex also includes a system for transporting products that are painted. Transportation is required in order to easily move the product between painting stages. This is especially important for car parts that are large in weight and size.

Before powder painting, the surfaces of car parts should be prepared. It is necessary to degrease it, clean it from rust and oxides, and then cover it with a layer of phosphate or chromate, which will ensure better adhesion of the powder polymer to the surface. When preparing for painting, you also need special equipment, which is included in a complete line for powder painting of cars.

Today, powder painting of parts in the production and assembly of automobiles has taken a strong leading position in comparison with other painting methods, as well as the application of polymer coatings. Using this technology, you can apply a coating to the body, fenders, wheels, reflectors, bumpers, plastic parts inside the cabin and many other design elements.

Decorating and styling cars 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 are aimed not only at the elegance and beauty of the appearance of the car. They combine the basic requirements: speed of execution, reliability and durability in operation, as well as an optimal ratio of quality to cost.

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

ChipsAway

This new technology was developed in the UK, so it allows you to repaint a car in the shortest possible time or get rid of minor damage to the body with the accuracy characteristic of the British. In Europe and America, more than 1.5 thousand large services have been opened that provide this service, while in the domestic market this technique is only gaining momentum.

The main difference between classical methods is that when painting, most often 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 caused the coating to 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.

Key benefits of ChipsAway:

• The technology allows for a minimal area of ​​surface preparation. With classical methods, the entire part is sanded, while with ChipsAway, the area of ​​the scratch or dent and a minimal area around it are sanded. This preserves the original factory finish as much as possible.
• Painting can be carried out without dismantling the part in a complete assembly, which allows you to maintain all factory settings and prevent the replacement of parts or damage caused in the process.
• Exceptional shade selection accuracy. The technique has in its arsenal a spectrum 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.
• The speed of painting a car according to this modern technology is several hours, and in the case of a large treated area - a little less than a day, after which the car can be operated as usual.
• The composition of the components in the coating solution consists of more environmentally friendly substances. Thanks to the new complex, the chemical formula of ChipsAway is compatible with any type of coating (factory or repair). During the painting process, no fumes harmful to the environment are generated.

Pigmented pastes are securely fixed using chemical additives that provide resistance to peeling, plastic filling during application and high adhesiveness.

EcoDryScrubber

EcoDryScrubber technology is developed, tested and patented by the German company Dürr, located in Stuttgart. This technique is used by concerns and large vehicle manufacturers because it is very profitable in economic terms: the cost of painting costs is reduced by 30-60%, which also affects the overall cost of the car.

Applying paint to a body is the most energy-consuming aspect 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 painting chamber, which eliminates the need for a powerful air purification system;
• dry filtration of pollutants present in process air;
• replacing hydrofiltration with recirculation allows you to save huge amounts of water;
• significant reduction in pollutant emissions.

Saving paint material during automatic painting using the EcoDryScrubber system reaches 85%. In addition, the system allows you to reduce the size 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 from an environmental point of view.

Powder painting

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

Advantages of powder coating a car:

• The polymer coating lasts 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 chamber a continuous static charge is supplied to the car, and the opposite pole is supplied to the powder paint machine. Due to mutual attraction, fine particles of paint settle in an even layer on the surface, forming a uniform tone on the body.

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

Vinyl cover

Vinyl wrap is an affordable, budget-friendly method to make your car stand out on the road by combining interesting design and reliability of the coating. The covering can be of different colors, but it can also be transparent - this satisfies the requirements of those people who do not want to change the chosen design.

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

Advantages of vinyl covering:

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

Self-adhesive vinyl film is completely weightless, it makes washing the car easier, and after removal it leaves absolutely no marks. The period of its use is unlimited, which allows you to get a guarantee of up to 7 years.

The film can be carbon, matte, glossy or natural. If desired, a drawing or inscription can be applied to it to emphasize the individuality of the product.

Metallic painting

This method requires highly qualified performers and automation of most stages. The fact is that metallic highlights all the imperfections and blemishes that were not visible before painting.

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

Advantages of metallic painting:

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

Disadvantages include the required thoroughness of preparation and the length of the process, since it occurs in three main stages. Strict adherence to the technology of labor-intensive procedures is the main key to success.

Paramagnetic paint

This innovative car painting technology has already been patented and is just getting ready to enter the production market.

The essence of the method is that before painting, a special polymer consisting of paramagnetic tiny particles of iron oxide is applied to the body. Using an electric current, the distance separating such particles changes, causing them to reflect different wavelengths 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 color. Using this method, you can give your car any color depending on your mood. It is expected that the cost of such painting will be quite high, so most likely it will not be possible to use it 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 also used it to provide the tint effect at the right time.

The issue of how to register the color of a car with paramagnetic paint in the registration certificate has not yet been resolved, but this moment this issue is being resolved.

This technology is used when it is necessary to replace one or more parts, but to make them fully compatible, they require a special coating.

Advantages of the wet-on-wet method:

• low cost;
• execution speed;
• the only need for sanding at the time of pre-painting preparation.

The main difference of this technique is that after applying each layer there is no need for sanding. The layers are applied to the untreated coating, which has not completely dried. Under such conditions, it is very important to exclude spray booth any specks and flying debris, since it will immediately settle on the wet layer and result in large errors.

New trends in painting consist of a transition from the use of standard paints in the auto industry to alternative materials that will ensure the durability and safety of the vehicle.

To apply liquid rubber, fundamentally new equipment is required, but its cost is not high, so innovative development is not expensive.

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

Advantages of using “liquid rubber”:

• inertia and stability against 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 the rubber improves vehicle performance during crash tests by reducing body fragility and inhibiting the formation of polymer fragments during a 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 present revolutionary technologies that can significantly expand the functionality and implementation of car painting.

In modern conditions body repair and painting work on the market exists a large number of proposals related to various technologies applying paint coating. Polymer car painting has recently become one of the highest quality and most popular options. You can do such work in just a few hours, and with your own hands, but the warranty on operation is about 10 years. If you decide to do everything yourself, then strictly follow the technology, do not skimp on materials, and keep in mind that you will need special equipment. If you are not ready for such an investment, then it makes sense to consider auto repair shops that offer polymer powder painting of both body parts and wheels.

Classification of polymer paints

Such polymer powder paints are divided according to the following characteristics:

1. In various color shades. Basically, the palette is taken from RAL.
2. According to the type of substance that forms protective film: based epoxy resins, polyester, polyester-epoxy, polyamide.
3. According to the structure and nature of the surface: matte, glossy, metallic, textured, moiré.
4. According to the type of functions performed: for protection against corrosion, for the formation of chemically resistant, electrical insulating and decorative coatings.

Preparing the surface for painting

The main process of surface preparation is to remove old paintwork, remove rust, chips and dents. It's actually very important stage, the results of which will depend appearance and coating service life. Old coating can be removed in several ways. There are mainly three of them:

Equipment for polymer painting

Here is a list of equipment you will need if you decide to use this type painting for commercial purposes.

1. Jet washing chamber.
2. Infrared drying.
3. Suspended transport system.
4. Oven for polymerization and baking of paint.
5. Tribostatic and electrostatic sprayers.
6. Air dryers.
7. Spray chamber with filters and cyclone.
8. Vibrating sieve.

This is the main list of tools that you will need to organize a mini business for polymer painting of parts.

Apply polymer powder paint

The technology for applying such powder paint is actually somewhat similar to using liquid materials, but has a number of advantages. It can also be applied in 2 – 3 layers, which ultimately ensures uniform coverage. Firstly, when working with powder paint, you will not have leftovers that you cannot reuse. This is a definite plus, since the loss of liquid paint residues reaches 40%, and this, in turn, is wasted money.

Secondly, this paint is environmentally friendly, and you will not have to breathe harmful fumes, but you should still wear a respirator to prevent inhalation of the powder itself. After you have applied the material with a powder paint spray gun, you need to move on to the next step.

Heat treatment of the material

This is an integral part of the car painting process. polymer composite. For heat treatment, the part with the applied powder is placed in an oven for 10 - 15 minutes, the temperature in which must be maintained at 180 - 200 degrees Celsius. Under such conditions, the polymer melts and adheres perfectly to the metal, gradually forming a layer of paint on it. As you can see, the formation of a film occurs within 15 minutes; in turn, such a material also cools down, crystallizing quickly. This significantly saves time on work. In addition to corrosion protection, such a polymer coating also provides high level strength to mechanical stress.

A few dings about cooling. After the part is removed from the oven, it is allowed to cool. Next, it is already fashionable to polish the surface. Another undoubted advantage is that using the polymer paint option for the car body, you can be sure of an exact color match from the RAL catalog.

At this point, the painting stage is completed, and the part or body can be used.

Here is a video tutorial that explains in practice all the basic steps of applying polymer paint.

Advantages of polymer powder paint

These are the main features because of which many car enthusiasts choose the option of polymer painting of the wheels or body of their car.

1. Saves money on material because there is no paint residue.
2. High quality protection against corrosion and mechanical stress and long service life.
3. Saving time on work.
4. A large number of colors of polymer materials.
5. Environmentally friendly material.
6. The simplicity of technology allows you to do everything yourself.
7. High wear resistance.

Disadvantages of this paint

As always, such material and the technology itself have certain disadvantages.

1. Bulk equipment that you will not buy for one-time use.
2. Quite a solid investment in such equipment.
3. Complex sprayer settings to apply a thin layer of powder to the metal.
4. It is not recommended to carry out such work at reduced temperatures in the workroom.
