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 and aluminum can be called embossing plate belonging to in the aluminum base, aluminum products after rolling processing and forming on the surface of various patterns, is widely used, mainly used in packaging, building a wall, belonging to the aluminum sheet aluminum coil, is actually a long and narrow and thin aluminum coil supply,
The difference between a roll and a flat is a tailored package.
Cold hard aluminum coils are hot rolled aluminum rolls through pickling and cold rolling. It can be said to be one of the cold rolled sheets.
Cold rolled sheet (annealed): hot rolled aluminum rolls are obtained through pickling, cold rolling, bell type annealing, leveling, and (finishing).
There are three main differences between the two.
1, the general appearance, a bit cold rolling aluminum micro Ukraine.
2, the surface quality, structure, size accuracy and other cold rolled plates are better than cold hard aluminum coils.
3, performance, as the hot rolled aluminum coil directly obtained through cold rolling process, the cold hard aluminum coil is hardened during cold rolling, resulting in increased yield strength and residual internal stress. The external performance is "hard", so it is called cold hard aluminum coil.
