Auto Paint Booth

Early cars produced, although the new car was very beautiful when it was shipped from the factory, it soon appeared blistered and rusty spots on the surface of the paint, usually need to be repainted every 2 to 3 years. The reason is that the adhesion ability of the paint film is not enough, and the corrosion resistance is poor. In order to effectively improve the life of the coating, the effective method is phosphating before put the auto pars into the auto paint booth. The use of the dissociation (equilibrium) reaction of phosphoric acid to precipitate an insoluble metal phosphate film (referred to as a phosphating film) on a clean metal surface can directly generate a phosphating film that is directly related to the cleanliness of the metal surface and the surface microstructure. In the process of parts stamping and welding, grease, rust or other residues will inevitably be left on the surface of the metal parts. For this reason, it is necessary to thoroughly degrease, remove rust and adjust the conditioning before phosphating; after phosphating, it is also necessary to thoroughly remove the phosphating solution remaining on the parts surface and the loose layer on the surface of the phosphating film, and phosphating The partial holes of the film are closed, so that the crystal of the phosphating film is refined, and its compactness (ie, passivation) is improved. The pretreatment of the car parts usually needs to undergo pre-cleaning, pre-degreasing, degreasing, water washing, surface conditioning, phosphating, water washing, pure.all of this measures should be making at auto paint booth.

Auto paint booth can hold more than 10 procedures such as washing and flipping drain.

The first five steps are degreasing and cleaning (degreasing) steps. Use hot water and hot alkali to spray and dip to clean the car parts. The purpose of degreasing is achieved by the alkaline substance in the degreasing agent saponifying the oil stain and the infiltration, dispersion, emulsification and solubilization of the surfactant. With the help of auto paint booth. such as pressure spraying and stirring, a good degreasing and cleaning effect can be achieved.

1. Electrophoresis layer: to achieve durability and corrosion resistance of automotive coatings.
2. Intermediate coating: Auto paint boothhas good adhesion and adhesion with the electrophoretic primer and topcoat coating film, crack resistance, weather resistance, improved topcoat hiding and advanced appearance functionality.
3. Colored paint layer: It is decorative, has good adhesion between the middle auto paint boothand thenvarnish, and has certain self-protection.
4. Varnish layer: in the outermost layer, combined with the color paint layer, it has the functions of UV protection, water penetration resistance, weather resistance, color retention, acid rain resistance, and scratch resistance.

The topcoat consists of two layers: a color paint layer and a varnish layer. The main function of the color paint layer is to decorate and make the car parts look good; the auto paint booth has the outermost layer of the coating, and its main functions are: UV protection, waterproof penetration, and resistance Cannibalism, color preservation, acid rain resistance, scratch resistance, etc.
