After anodic oxidation process of industrial aluminum profile, the surface of aluminum is not smooth, which may be caused by the defect, which may be caused by the high content of sodium cyanide in the tank liquid, acid and alkaline corrosion. There may also be defects in the internal mechanism of aluminum causing the surface is not smooth.

If the copper content in the tank is also high, the unsmooth surface will be more serious. Usually, if the content of sodium cyanide in the tank is too high, the anodic oxidation process reflects strongly, resulting in "boiling" condition. If the content of sodium cyanide is normal and the content of copper is high, the surface of aluminum after water cleaning will adhere to a very significant layer of metallic material copper symptom tone. If the symptom of copper is dark, the copper content in the surface tank is high, and some effective measures should be taken to adjust the content of sodium cyanide and copper to the conventional range. If the content contains copper, add as little as possible; If the copper in the tank solution comes from the anodic oxidation process of copper aluminum material, some effective measures should be taken to add non-copper additives or adjust the tank solution.

If the internal mechanism defects of aluminum cause the surface is not smooth: casting mechanism, glass doors with aluminum profiles such as casting or aluminum die-casting aluminum product workpiece; Aluminum crystal optimization is not sufficient and loose, welding defects; In the process of production, defects such as inadequate shape variables and pine dendritic lines lead to uneven surface, which can be avoided by improving the internal quality of aluminum. Therefore, the processing technology of hengzhixing aluminum alloy profiles seems to be very important to improve the surface quality of anodic oxidation process. Industrialaluminum profile English name, Industrialaluminum, alias: industrial production of aluminum. Industrial aluminum profile, is a kind of aluminum as the primary active component of alloy products, aluminum ingot after hot melting, extrusion and then obtain different section appearance of aluminum, but the percentage of aluminum alloy is not the same, the production of industrial aluminum profile physical properties and main uses are not the same.

Industrial aluminum profile surface is not smooth reason and aluminum profile manufacturers to deal with countermeasures
