1. Electrolytic oxidation coloring. When the aluminum alloy is placed in an appropriate electrolyte as an anode for electrical treatment, oxide film with a thickness of several to dozens of micrometers will be generated on the surface, and the surface of oxide film will be porous honeycomb.
2. Powder spraying. The powder coating is evenly sprayed on the surface of the profile, and the coating film is formed by highbake. 120um> film thickness> 40um coating is compact, with strong adhesion, super corrosion resistance, strong impact resistance and good toughness.
3. Wood grain transfer. Using the principle of heating biochemical membrane penetration, transfer wood-grained film on the surface of bridge-cutoff aluminum alloy materials. Advanced technology, excellent performance, not easy to fade, realistic wood grain, and extremely decorative.
