Aluminium plate texture of light, stylish and beautiful by the majority of people of all ages. However, in the processing of aluminium, the oxide film tends to appear uneven phenomenon. In the end what is the oxide film is not uniform, how to solve it?
1. aluminium area is too large, in the work of the tank swing range is too large, that is, the central parts and the edge and the solution contact is too large, which led to the color of the oxide film is not the same. It is possible to reduce the wobble of the workpiece by oxidation of the aluminium plate, or by static treatment.
2. In the processing of aluminium plate processing, there is a part of the package of aluminium damage, part of the cut, formed on the inner layer of the package is not good miscellaneous aluminium, the outer layer is high quality
aluminium plate. Resulting in white spots after oxidation of aluminium plate.
3. Improper operation of the process. The general process operation will appear in 3 cases, the workpiece alkali corrosion is not clean, resulting in local raw oxide film is not removed; after alkali corrosion is not timely light, resulting in the industrial surface there is alkaline; in the industrial transmission process In contact with other things.
I believe we read the above principles of the oxidation of aluminium plate have a better understanding, but also learned how to avoid the phenomenon of
aluminium plate oxide film uneven color.
