Alumina plate

1, high hardness, good corrosion resistance

Anodic oxidation experiments, the aluminum plate in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode in the specific conditions and the role of external current, the electrolysis. The aluminum plate of the anode is oxidized, and a thin layer of aluminum oxide is formed on the surface thereof, the thickness of which is 5 to 20 m, and the thickness of the hard anodic oxide film is 60 to 200 m. Products with high hardness, good insulation, corrosion resistance, strong adsorption and so on.

2, anti-fouling fire, high security

Products do not leave fingerprints on the surface, there will be no trace of stains, easy to clean, do not produce corrosion spots. The surface without any chemical substances and paint, 600-degree heat does not burn, does not produce toxic gases, in line with national environmental requirements of fire protection.

3, good weather resistance, suitable for processing

Standard thickness of the oxide film (3μm) anodized aluminum plate indoor use long-term non-color, no corrosion, no oxidation, no rust. Anodized aluminum oxide with thickened oxide film (10μm) can be used outdoors, and will not change color when exposed to sunlight for long periods of time. Products can be continuous high-speed stamping, to facilitate direct processing into products, no need for complex surface treatment, greatly reducing the short production cycle, reducing production costs.
