Brushed aluminum plate: The manufacturing process of repeatedly scraping the aluminum plate out of the line with sandpaper. The main process of the process is divided into three parts: deesterification, sand mill, and water washing. In the aluminum sheet drawing process, the special film technology after anodizing can make a film layer containing the metal component on the surface of the aluminum sheet, and clearly show every fine wire mark, so that the metal matte shines with fine hair. Silky sheen. Alumina plate: The aluminum plate is formed by placing the aluminum plate in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and performing electrolysis under specific conditions and applied current. The aluminum plate of the anode is oxidized, and a thin layer of aluminum oxide is formed on the surface, the thickness of which is 5~20 microns, and the hard anodized film can reach 60~200 microns.
PS aluminum plate (advertisement aluminum plate, also known as printed zinc plate, newspaper plate): that is, an aluminum plate with a printed pattern on the back and a thickness of 025 or 03.
