The production of color-coated boards adopts the production process of two coats and two bakes. In order to ensure the coating quality of color-coated products, the surface of the substrate needs to be degreased, dusted, and rust removed before coating. This is the first step to ensure the coating process and the basic work to ensure the quality of color-coated board products. The purpose of the treatment is to remove the anti-rust oil, rust spots, dust, etc. attached to the surface of the substrate, and perform chemical coating treatment on the surface of the clean substrate to form a mesh chemical conversion film with Cr6 + and Cr3 + as the basic skeleton, so as to increase the adhesion between the substrate and the coating, improve the corrosion resistance of the substrate and the durability of the coating. The quality of work determines the quality of the coating, and directly affects the flexibility, impact resistance and other physical indicators of the coating. Determines the coating adhesion of color-coated board products. The purpose of primary coating, fine coating and curing is to apply the coating to the surface of the substrate and use heating to volatilize the organic solvent of the coating, so that the organic coating and the substrate are closely combined.
The product quality of color-coated board is not only determined by the basic properties of the substrate and coating, but also depends on the production process and operation control technology. Operation control technology has a great impact on the physical properties and surface quality of color-coated board products. From the analysis of the production process, the focus of production control technology should include four links: cleaning treatment, chemical coating treatment, coating (including initial coating and fine coating), and curing.
