There are many factors in the processing of Color Coated Steel Coil, which will damage the quality of color steel coil products. Today, I will come to know the reasons that affect the quality of Color Coated Steel Coil.
The product quality of Color Coated Steel Coil is determined not only by the basic characteristics of the sheet and industrial paint, but also by the processing technology and the use of the control system. The use of the control system is very harmful to the process performance and process performance of the color coated board products. From the processing technology analysis, the weight of the manufacturing control system should include cleaning, solving, spraying and drying.
Color Coated Steel Coil manufacturing uses two coating and two baking processes. In order to ensure the coating quality of color coated products, it is necessary to carry out early solving work such as degreasing, ash removal and anti-rust treatment on the surface of the board before coating. It is to ensure the quality of the color-coated board products at the beginning of the painting process. Basic work. The purpose of the Color Coated Steel Coil is to remove the rust inhibitor, rust, dust, etc. adhered to the surface layer of the sheet, and then carry out biological coating on the surface of the cleaned sheet to produce a honeycomb biological conversion film with a base support plate. This improves the adhesion between the sheet and the coating, and improves the rust resistance of the sheet and the performance of the coating.
The quality of the workmanship determines the quality of the spray quality, and immediately compromises the mathematical index of the flexibility and impact resistance of the coating. The coating adhesion of Color Coated Steel Coil and color coated board products was decided. The purpose of initial coating, fine coating and dry solidification is to apply industrial paint to the gluten of the board and use the heating method to evaporate the high boiling point solvent of the industrial paint, so that the inorganic coating is closely related to the sheet.
The above is the factor that affects the quality of the Color Coated Steel Coil. Another color steel coil has two kinds of poor luster. Once the coating is dried, it does not reach the required smoothness or uneven color, or it is dry in the coating. After a few days, or after application, the brightness will be reduced and the light will be reflected.
