Professional China Curtain Aluminum Profiles - Anodized Aluminum Profiles Anodized Aluminum Extrusions – Rizhaoxin Detail:
Product Description
Anodized aluminum profile refers to a layer of dense aluminum oxide coated on the surface of aluminum and aluminum alloys. In order to prevent further oxidation, its chemical properties are the same as aluminum oxide. But unlike ordinary oxide films, anodized aluminum can be dyed with electrolytic coloring.
Anodizing can significantly improve the corrosion resistance of aluminum alloys, improve the surface hardness and wear resistance of aluminum alloys, and have good decorative properties after appropriate coloring treatment. Aluminum and its alloy anodized film coloring technology can be divided into 3 kinds: chemical dyeing, electrolytic coloring and electrolytic overall coloring. Chemical dyeing is to use the porosity and chemical activity of the oxide film layer to adsorb various pigments to color the oxide film. According to the coloring mechanism and process, it can be divided into organic dye coloring, inorganic dye coloring, color paste printing color, over-color dyeing and achromatic dyeing. Wait. Electrolytic coloring is to perform AC electrolysis on anodized aluminum and its alloys in an aqueous solution containing metal salts, and deposit metals, metal oxides or metal compounds at the bottom of the porous layer of the oxide film. Shows a variety of colors. Electrolytic overall coloring means that aluminum and its alloys are colored at the same time as anodizing. It is characterized by one step of oxidation and coloring, and the colored film has good light resistance, heat resistance, corrosion resistance and wear resistance. Electrolytic overall coloring is further divided into natural hair color, electrolytic hair color and power hair color method, among which electrolytic hair color is dominant, followed by natural hair color, and power hair color is under development.
