Technology and Development of Automatic Spraying Line

The coating process consists of two parts: pretreatment and painting. The quality of the surface treatment of the painting line directly affects the adhesion of the coating to the substrate of the coated workpiece and the corrosion resistance of the material. Therefore, in order to obtain high-quality products, surface treatment must be strictly applied before painting. Through pretreatment, the workpiece meets the following requirements: 1 No oil stains; 2 No rust and oxide; 3 No acid, alkali and other residues; 4 The surface of the workpiece reaches a certain roughness.

In the design of Zhongyan Technology, appropriate coating and pretreatment processes should be adopted to meet the product's surface gloss and corrosion resistance requirements. The surface treatment process has a significant impact on the quality of the painted surface. Therefore, the solvent used in each process should be carefully selected. With the advancement of technology, new requirements have been put forward for the coating of new products. Painters should actively adopt and digest new foreign techniques and equipment in order to upgrade their products in painting.
