Product quality is not only determined by the color-coated substrate and the basic properties of 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 adhered to the substrate surface after removal of the anti-rust oil, rust, dust, etc., in a clean substrate surface chemical coating process, the formation of Cr6 + and Cr3 + into the chemical basic skeleton of the mesh film, thereby color coated coil price increases 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 paint color coated coil volatile organic solvent, so that the organic coating and the substrate closely. Coating, curing a direct impact on the quality and appearance of color-coated physical and chemical properties, are key aspects of production control. Color-coated paint is from which parts, its performance, features how? A: usually by coating the membrane material, pigments, fillers, solvents and additives consisting of five substances, the composition of each of these five applications in coatings have played a very important role. A film material properties, film-forming characteristics of the coating material on generally include: oil, natural resin, phenol resin, pitch, alkyd resins, amino resins, cellulose, vinyl chloride resins, ethylenic resins, acrylic resins, polyester resins, epoxy resins, polyurethane resins, organic elements, rubber, other (inorganic polymer, xylene resin and the like). Film material is generally divided into two categories: the first category consisting of structural changes during film formation does not occur, that the same composition and structure of the coating film material, such film material called non-transformed film material, They have a thermoplastic, heat soften hardened after cooling characteristics. Another refers to the composition during film formation changes in the structure, namely the formation of membrane material composition and structure of the original film Boxing completely different color coated paper, film-forming substances called transformation, these film-forming substances heat, oxygen or other substance capable of polymerizing into effect with a different composition of the original mesh insoluble polymer. The feature film material is Yan, filler and resin together Shandong color coated paper, on the substrate to form a uniform, dense coating, forming a coating after curing, it is the basis of the paint, the decision is attached to the substrate coating focus, physical coating, chemical and mechanical properties. B performance color pigments, pigment characteristics can generally be divided into two categories: the coloring pigments and extenders, fillers, also called an extender pigment, they are not alone film. It is the main component of the coating, accounting for 70% to 80%. Coloring pigment is an insoluble in water, soluble solid powder oil, its main role is to present the colors, and has a protective and decorative performance, combined with colored pigments and binders while Huanggang color coated paper, Hong color coated paper, Jinhong Run steel (certified merchants) provided by Boxing Xingfu Town 金宏润 Steel Industry and Trade Ministry.
