Drawing aluminum sheet: the process of repeated use of sand paper to scrape the aluminum sheet out of the line. The main process is divided into 3 parts: deester, sand mill and water washing. In aluminum wire drawing process, anodized after special coating technology, can make the surface of aluminum to form a coating layer containing the metal component, clear every fine wire mark, so that the pan fine hair gloss matte in metal.
Aluminum oxide plate: aluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as anode, and the aluminum plate is formed by electrolysis under specific conditions and applied current. The aluminum oxide on the anode forms a thin layer of alumina on the surface, with a thickness of 5~20 microns and a hard anodic oxide film of up to 60~200 microns.
PS aluminum plate (advertising aluminum plate also known as printed zinc board, newspaper board): the back has a printed pattern thickness of 025 or 03 aluminum plate.
Mirror aluminum sheet: refers to the aluminum plate on the surface of the plate which is treated by various methods such as rolling, grinding and so on.
Embossed aluminum sheet can also be called aluminum embossing board: it is a kind of aluminum product that is formed on the surface of aluminum sheet by calendering, and is widely applied to packaging, building, curtain wall and so on.
