Anodized alumina single board production process
[China Aluminum Network] Anodized aluminum veneer process flow is different from the ordinary painting process, it electrolysis of the conductive acidic electrolyte through the current, the oxidation of the aluminum metal surface constitutes the anode, a layer of natural growth in the aluminum surface The dense alumina protective film, this oxide film is not an additional layer, will not peel off. Oxide film is transparent and colorless, and its microcrystalline structure is hexagonal honeycomb. It can use aluminum color to highlight the strong metal feeling, and can evenly color in the micro-holes to give beautiful color to the curtain wall, which greatly expands the application horizon.
Performance: The standard thickness of the oxide film (3um) of the anodized aluminum single-plate indoor use for a long time does not change color, no corrosion, no oxidation, no rust. Anodized aluminum veneers with a thicker oxide film (10um) can be used outdoors and can be exposed to sunlight for long periods of time without discoloration.
