Automotive sheet metal spray paint is divided into 3 steps:
1, the first primer, fill the sand marks and microporous workpiece substrate, increase the adhesion of the next layer of paint, but also with defects in the indication of the role of.
2, in the paint primer, a very important part of the coating, for the top coat to prepare a complete and smooth working surface, to complete all the primer work of the last process, to increase the adhesion of the intervening layer, as well as with a certain degree of isolation, in order to ensure that the quality of the top coat of stability.
3, top coat, top coat is divided into single-layer paint and multi-layer paint, is the color of the layer of certainty and decorative protection layer, single-layer paint we commonly known as plain paint, also known as ordinary paint, can be a layer to complete. Multi-layer paint is divided into silver powder series paint and pearl series paint, divided into double-layer and multi-layer construction process to complete the paint, silver powder paint is made of special aluminum material by research and become.
Expanded Information:
Painting process, for the need to repair the surface of the body of the car is crucial, if not handled well, not only the surface feels rough and uneven, but also bring back to repair, directly affecting the owners of the service satisfaction.
As an important process in sheet metal spray repair, the surface treatment in the past has been based on the traditional wet grinding process, which has increasingly exposed the hidden quality problems.
The dry grinding process is used in the prototype store for surface treatment. The pneumatic or power tool grinding method used in "dry grinding" not only effectively removes the dust generated in the repair, but also improves the repair efficiency and guarantees the results.
