fter aluminium oxidation, the original physical shape can not be restored.

West Aluminum-West Aluminum Industry Telecom: after aluminium oxidation, the original physical shape can not be restored. Because the oxidation reaction occurs between molecules, the metal bond interaction between them can not be restored, and can only be restored to the furnace after reduction.


Cleaning steps of aluminium surface oxidation treatment:


A. Water slurry after degreasing of aluminium surface treatment: MIL-A-8625 should be washed twice. The purpose of aluminium oxidation coloring is to wash the residual drug (or acid or alkali). If solvent emulsifier is added to degreasing agent, cleaning is more important. Or oil pollution. Prevent from bringing in the subsequent tank fluid to affect the stability of tank fluid and prevent the product from producing bad products with oil contamination. The two washes can not be used as overflow, and can be replaced regularly depending on the workload.


B. Washing after alkali corrosion: at least three times. The purpose is to wash out the sticky alkali etching tank liquid film on the surface of aluminium material after alkali etching. Because it is difficult to clean, it is suggested that the water in one tank should be replaced as little as possible to ensure a certain temperature and alkalinity, which is conducive to cleaning products. If the latter two tanks are conditional, the stirring effect will be better. The two washes can not be used as overflow, and can be replaced regularly depending on the workload.


C. Washing after chemical (electrolytic) polishing: It is enough to wash twice. The purpose of aluminium oxidation coloring is to wash off the viscous chemical parabolic liquid on the surface of aluminium materials. It is suggested that the first tank should be guaranteed to have a certain temperature to facilitate product cleaning. The second flume can be cleaned by circulating flowing water. (After electrolysis, the membrane removal process should be added and then washed twice)


Aluminum oxidation treatment of grinding fabrics profiles: grinding surface aluminum profiles avoid the shortcomings of bright aluminum profiles in architectural decoration, which can form light interference under certain environment and conditions. Its surface is as delicate and soft as brocade, which is very popular in the market. However, the existing grinding materials must overcome the uneven surface sand grains and can see the shortcomings of patterns.
