Anodized aluminium coil mainly the anodic oxidation of aluminum, is the whole process of forming a high-density oxide film on the surface of the aluminum coil under the acidity and alkalinity of the solution using the basic principle of photoelectric catalysis, which is called surface anodic oxidation. The anodized aluminum coil is to place the aluminum coil in the relative lithium battery electrolyte (such as hydrochloric acid, chromic acid, hydrochloric acid, etc.) for anodic oxidation, and carry out electrolysis under special conditions and the effect of additional current.
After anodising processing, the coil anodized aluminum have a good performance.
1, Good process performance:
Anodized aluminum coil has strong decorative art and moderate strength, and can be bent and formed by sheet metal at will.
2, Good aging resistance:
The anodized aluminum sheet will not fade, corrode, oxidize or rust for a long time.
3, Heavy sense of metal material:
The surface strength of the anodized aluminum sheets is high, reaching spar level, good scratch resistance, no paint covering the surface, preserving the color of the metal material of the aluminum coil, highlighting the sense of modern metal material, and improving the product level.
4, Strong fire resistance:
Made of pure metal, without paint and all chemical substances on the surface, does not ignite at a high temperature of 600 degrees, does not produce harmful gases, and meets fire safety and environmental protection regulations.
5, Strong stain resistance:
no fingerprints are left, there will still be stains and marks, it is easy to clean, and does not cause corrosion spots.
6, High strength:
The surface strength of the anodized aluminium coil is high, up to spar level, and has good scratch resistance.
