Why is the original car paint so unique？

The original car paint includes the electrophoretic layer, the middle plating layer, the varnish layer and the topcoat layer. On the surface of the metal material substrate, I think there are also layers of phosphating treatment film, which produces a layer of high-density passivation treatment layer, the effect is to prevent the metal material substrate from being corroded by the outside.

1. Electrophoresis layer

In the spraying production workshop of the car factory, a pre-painting solution will be carried out on the car body to make it exceed the electrophoresis regulations. Next, layers of electrophoretic paint film will be adhered to the metal material car hands, which can prevent the metal material from rusting, which is what we often call the top coat.

2. Medium plating

Carry out the actual operation in a clean natural environment and apply it on the electrophoretic layer to balance the adhesion standard for the supply and demand of the varnish, which can improve the anti-corrosion maintenance of the car body. After the completion, it is air-dried in a natural environment at about 140 ℃.

3.the varnish layer

In the natural environment of the Sanheng system, the different colors are sprayed on the computer, which means that the color of the car body that people see, the varnish layer can also effectively enhance the effect of the car body's anti-corrosion maintenance.

4. the top paint layer

The same is automatically sprayed by the system to become a layer of transparent electroplating paint on the outermost side of the car. And after all the painting is finished, it must be air-dried in a drying oven at a temperature of hg140℃-180℃. It is used to maintain the hue of the car body and avoid minor scratches.

As mentioned above, the initial car paint is sprayed under the control of a clean natural environment electronic computer. In addition, the door frame cover and other components are immediately in the car factory, usually inspection shops and car 4s do not have this situation. After painting, the post-treatment process is carried out according to the whole process of dryness, water cooling and final product quality inspection. At this time, the polishing paste is released on the surface of the car, so that the top plating layer has a soft and smooth gloss.
