(Summary description)After the surface of the aluminum plate is degreasing and chemically treated, it is made by rolling high-quality paint and drying and curing. The smoothness of the paint film on the surface of the roll-coated board is higher than that of the spray-coated board. The color is divided into pearlescent and matte, and most of the common ones on the market are pearlescent. Its price is higher than spraying. The biggest feature of the roll-coated board is the high degree of color simulation; the quality of the roll-coating process varies greatly. In addition to all the materials, it is also related to the coloring in several times, such as two coatings and two rolls. It is to spray once and bake once, and then spray and bake again, so that the color is more even and smooth. A good roll-coated plate is also very expensive, the color is realistic, and the durability is strong. Imported fluorocarbon roller coating is also a type of roller coating, which is to add fluorocarbon to the pigment, which makes the color adhesion stronger, longer service life, acid and alkali resistance, and is often used for the exterior decoration of buildings (not afraid of wind Blowing rain), the price cost is very high, it is the most high-end kind of roll-coated board. The surface treatment process of the roller-coated plate is as follows: The roller-coated plate has a top coat, a primer, and a back coating. The back coating mainly plays a role of anti-oxidation and makes its service life longer. Semi-finished products-on the machine-forming-the next part and inspection-packaging and warehousing. The surface of the roller-coated plate is uniform, smooth, and has no obvious defects such as missing coating, shrinking holes, scratches, and falling off. However, there are minor defects such as bubbles, pits, and inclusions on the surface, which are normal phenomena.
