Industrial aluminum profile application field is very wide, there are equipment frame, workbench, conveyor line frame, rail transit, mechanical equipment accessories and so on.
Industrial aluminum profile corrosion resistance, beautiful surface, industrial aluminum profile surface is a natural silver white, very beautiful.
But a lot of industrial aluminum profile surface will be black, dark, very affect the beauty of the equipment, today to analyze the reason for the surface of industrial aluminum profile black.
1. Material problems, some industrial aluminum profiles just bought back the surface of the black, dark, this should be the material problem, the iron content of aluminum alloy exceeds the standard, some use waste aluminum smelting, such industrial aluminum profiles are cheap, but the mechanical properties are obviously not enough.
2. No anodic oxidation treatment, that is, we commonly known as the substrate, material, the surface of this industrial aluminum profile has not been oxidized, only the natural formation of uneven, very thin oxide film, because aluminum is a lively metal, under certain temperature and humidity conditions more prone to oxidation black, mildew.
3. The cleaning agent has a certain corrosive, if the residue is too much when cleaning the industrial aluminum profile, it will cause corrosion to the industrial aluminum profile.
4. Some industrial aluminum profiles need deep processing after production, and milling, drilling and other deep processing need spraying emulsifier, so the finished processing of industrial aluminum profiles need jet cleaning.
Some manufacturers in order to save costs do not clean, or cleaning is not thorough, resulting in the emulsifier residue, over the years, cause corrosion to aluminum profiles, cause the surface black.
