Process Flow Of Black Anodized Aluminum Sheet

Aluminum anodizing process flow:

Mechanical polishing -- oil removal -- washing -- chemical polishing -- washing -- anodizing -- washing -- sealing -- mechanical bright.

Chemical polishing products: Aluminum alkaline polishing liquid anodizing products: aluminum anodizing liquid blocking products: aluminum coloring blocking liquid aluminum anodizing and dyeing process

Aluminum products treated by dyeing have beautiful color, bright color, corrosion resistance, wear resistance and insulation higher than ordinary aluminum products. The aluminum workpiece is suspended in a suitable electrolyte solution and used as an anode for electrolysis. In the process of electrolysis, the hydroxide ion in the water emits electrons at the anode to become water and oxygen of the new ecology, which makes aluminum oxide into a thicker aluminum oxide film, because this process is the anodic oxidation of metal products, so it is called anodic oxidation. After anodic oxidation, aluminum products are stained, closed and treated.
