The quality of stainless steel color coated products depends not only on the basic properties of the substrate and coating, but also on the production process and operational control technology. The operational process has a significant impact on the physical properties and surface quality of stainless steel color coated products. From the perspective of production process analysis, the key points of production control technology should include four stages: cleaning treatment, chemical coating treatment, coating (including initial and final coating), and curing. The stainless steel color coating production line adopts a production process of two coatings and two baking. In order to ensure the coating quality of stainless steel color coated products, it is necessary to perform pre-treatment such as degreasing, dust removal, and rust removal on the substrate surface before coating. This is the step to ensure the coating process and the basic work to ensure the quality of stainless steel color coated products. The purpose of the treatment is to remove rust proof oil, rust spots, dust, etc. Adhere to the surface of the substrate, and then apply chemical coating treatment to the clean substrate surface to increase the adhesion between the substrate and the coating, improve the corrosion resistance of the substrate and the durability of the coating. The coating of stainless steel color coating is done by using a roller coating machine to apply primer, topcoat, and back coating on the surface of the substrate. By heating and curing, the organic solvent of the coating evaporates, making the organic coating tightly bond with the substrate. During the homework process, Xinyu employees always pay attention to the constant temperature control of the paint room and the paint mixing room to ensure the stability of the paint viscosity. Curing is a key process in the production of stainless steel color coating. After coating the steel plate, it is necessary to heat the solvent in the wet coating to evaporate, and at the same time, organic compounds will undergo polymerization or cross-linking reactions under the action of catalysts. Curing not only firmly binds the coating to the strip steel, but also gives it certain mechanical and physical properties. Therefore, Xinyu curing technicians strictly control the curing process to ensure the performance of stainless steel color coated products. Storage, transportation, and loading and unloading are important links that affect the quality of color coated steel coils. If operated improperly, various defects may occur during storage, transportation, and loading and unloading, such as scratches, imprints, corrosion, etc.
