Polished aluminum sheet and mirror finish anodized aluminum sheet represent two typical types of aluminum mirror sheets in the market.
How to distinguish between polished aluminum mirror sheet and mirror finish anodized aluminum sheet? Many methods, such as tear protective film on the surface of the can, and then touch the mirror, see the perspiration will stay above, and then clean the paper, look at that, if left no trace, is after anodic oxidation treatment, and if not only left hand finger print, and the clean the dirty of that kind of is the mirror polishing. Another approach is to bend the aluminum around the ear and listen for specific sounds that, if slightly broken, are anodized, whereas polished ones do not. Another method is to bend the product at 90 degrees T. The product with good quality will have slight bleaching. When the anodized film is burst, it will have bleaching, while the product with poor quality will not have such condition.
Anodized aluminum plate is to place the Aluminum Plate in corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode for electrolysis under specific conditions with externally applied current. The Aluminum Plate of the anode is oxidized and has an aluminum oxide film formed on the surface; the film is 5-20μm thick, and a hard anodic oxidation film can be up to 60-200μm thick. After anodization,
haomei Aluminum anodized aluminum plate hardness is relatively high, good scratch resistance, paint-free surface, anti-fouling effect is very good. Metallic aluminum ceiling, Curtain wall aluminum, as well as fire board, cellular aluminum, aluminum veneer is made of anodized aluminum plate for processing products
The aluminium oxide plate is placing the aluminum sheets inside the oxidation tank, and the aluminum oxide film is formed on the surface of the aluminum plate after conducting electricity, so that the aluminum plate has various products with different characteristics. It can be said that the oxidation of aluminum sheet as the main film, relying on the density of the oxide film, protection, bonding, so that the aluminum oxide sheet has a variety of special properties.
