Caitu in industrial applications is very broad, here are a few relevant knowledge under caitu color coated steel is an organic coating applied to the surface of the steel, it has a beautiful appearance, colorful, high strength , good corrosion resistance, ease of molding, but also allows users to reduce costs and reduce pollution. Caitu also called organic coating or pre-coated steel plate, which is a metal coil (cold rolled plate, galvanized plate, aluminum plate, high aluminum plate, stainless steel, etc.) as the substrate, the surface coating various organic or laminate coating or plastic film is made. Because it is a complete coil surface coatings in metallurgical plants, directly processed into products for users, so also known as pre-coated membrane. Product quality and color-coated not only determined by the color-coated color steel color steel basic properties of the substrate and the coating, but also on the production process and operation control technology. Operation control technology on the physical properties of color-coated products, surface quality large production control from the production process analysis techniques focus should include the cleaning process of coating treatment, coating (including early Tu, Tu Jing), cured four links . Queensland color coated steel production is produced using two bake two coating process, the process shown in Figure 1. In order to ensure quality of the coating color coated products, required prior to coating the substrate surface oil, dust, rust and other pre-processing work, which is the first step to ensure the coating process, but also to ensure product quality, color-coated basic work. The purpose of treatment is to remove the rear surface of the substrate attached to the anti-rust oil, rust, dust, etc. Shandong color coated on the substrate surface cleaning chemical coating treatment Boxing caitu form to Cr6 + and Cr3 + as the basic skeleton mesh chemical conversion coating, in order to increase the adhesion between the substrate and the coating to improve the corrosion resistance of the substrate and coating durability. Pre-treatment (cleaning and coating of) the quality of the coating quality is good or bad decision, and directly influence decisions flexible properties of the coating, impact resistance and other physical indicators. Determines the color-coated products, coating adhesion. Early painted, fine coating, curing purpose is to paint is applied to the substrate plate surface and the use of heating the coating of volatile organic solvents, organic coating and the substrate so closely. Coating, curing a direct impact on the quality and appearance of color-coated physical and chemical properties, are key aspects of production control.
