Color-coated panels are based on metal coils, and various organic coatings and plastic films are coated or laminated on the surface. Widely used in the production of sheet metal parts for home appliances, furniture, and curtain walls. As the utilization of color-coated panels becomes more and more common, its quality is also getting higher and higher. The production of color-coated panels provides a new type of material with many colors and complete specifications for construction, home appliances, electrical, vehicle and other industries. However, some shrinkage problems often occur in production, which has a certain impact on products.

　　Production process of color-coated board

　　The production process of color-coated boards has developed from one coating and one baking to two coating and two baking. At present, the commonly used processes are mostly two coating and two baking, which requires three coating and three baking with higher protection requirements. In addition, in order to enrich the color of the board, the embossing or transfer process is added on the basis of the original solid-color plate, so that the color-coated board can produce more personalized products. Color-coated boards can be divided into coated boards, embossed boards and printed boards according to product types.

　　So how to solve this shrinkage problem? Please refer to the following three points. Let's find out:

　　The curing time of the coating should be much greater than the leveling time;

　　The leveling time is greater than the defoaming time;

　　Control the surface tension of the color-coated board coating, so that the surface tension of the coating is less than the surface tension of the substrate, and even less than the surface tension of some basic pollutants.

　　Mastering the above three production skills can better improve the shrinkage problem of color-coated boards. In addition, attention should be paid to all aspects of the environment, production process and other details in production. Do you know the introduction of color-coated boards?
