Extended data;
Automotive sheet metal painting is usually divided into three steps;
< 1 > first primer
Filling the sand marks and micropores at the bottom of the workpiece increases the adhesion of the lower coating and also has the function of defect indication.
< 2 > perfusion.
In the very important painting part, a complete and smooth working surface is prepared for the topcoat, and the last procedure of all primer work is completed, which increases the adhesion of the intermediate layer and has a certain isolation effect, ensuring the quality stability of the topcoat.
< 3 > topcoat
Top coat is divided into single-layer paint and multi-layer paint, which is a color fixing layer and a decorative protective layer. Single-layer paint is collectively called plain paint, also known as ordinary paint, and one layer can be completed.
Multi-layer paints are divided into silver powder series paints and pearlescent series paints, which are completed in two-layer and multi-layer construction procedures. Silver powder paint adopts special aluminum material, which has high protection, strong outdoor stability and strong observability. Pearl series paint is made of mica and shells through high technology, which is a kind of high-grade paint with rich colors and strong decoration.
The spraying quality of topcoat is very high. It is not easy to be clean, plump, bright, not sagging, not hanging flowers, uniform luster, not leaking flowers, not flashing flowers, good leveling, not biting, not impetuous, not color cast. It's really not easy to accomplish these things in one go, which requires extremely rich experience and troubleshooting ability.
