The surface treatment of color coated aluminum coil mainly includes spraying, rolling and lamination. With the development of science and technology, new technologies for surface treatment of color-coated aluminum coils continue to emerge.
Color Coated Aluminum Coil
Spraying: The surface of the 3105 Aluminum Coil is sprayed with colorful paint, and then dried. The color distribution of the sprayed aluminum coil is uniform, and the color of the aluminum coil with poor coating is corrugated from the side. The spray paint is mostly matte, and the folds have right and beveled angles. Color-coated aluminum panels must be dry to make the paint film firm. The front and back color of the painted aluminum sheet coil for ceiling is the same, while the front and back color of the painted 1060 Aluminum Coil are different.
Roller coating: After degreasing and chemical treatment on the surface of the aluminum coil, a high-quality coating is rolled and dried to cure. The smoothness of the paint film on the surface of the roll-coated multi-coated aluminum coil is higher than that of the sprayed aluminum coil. The color is divided into pearlescent and matte, and most of the common ones on the market are pearlescent.
Lamination: Using color-coated aluminum sheet as the base material, using high-gloss film or magic color film, coating the surface of the sheet with professional glue and then compounding. The laminate has a bright sheen and is available in a variety of colors. Color-coated aluminum coils with laminated film are waterproof and fireproof, with excellent durability (weather resistance, corrosion resistance, chemical resistance), antifouling ability and excellent UV resistance. The membrane is divided into imported membrane and domestic membrane LG membrane. The durability and gloss of imported films are better than domestic films! Most of the high-quality aluminum gussets on the market use Korean LG film, and the thickness of the aluminum gussets should be about 0.6mm.
