After aluminum oxide can not restore the original physical appearance. Because of oxidation reaction is between molecules, can't restore the metallic bonding interaction between, can only be recycled after reduction.

Aluminum surface oxidation treatment of cleaning steps:

A. aluminum surface treatment of oil removal (skim) after water washing: should MIL - A - 8625 with two water washing, aluminum oxidation coloring the purpose is to wash the residual liquid product (or acid or alkali, if in addition to adding solvent emulsifier agent, cleaning is more important.) Or oil. Prevent into bath then influence the stability of the bath and to prevent and non-conforming products with grease. The overflow water can be used twice, depending on the workload change regularly.

B. after alkali corrosion of water to wash, need at least 3 times wash. Purpose is to wash out after alkali corrosion of the surface of the aluminum thick alkali corrosion groove residual liquid membrane, due to the difficult to clean, suggestion was a sink of water to minimize change number, guarantee a certain temperature and basicity, which facilitates cleaning products. The latter two sink conditional word, can increase mixing effect is better. The overflow water can be used twice, depending on the workload change regularly.

C. chemical (electrolytic polishing after washing: have two water washing line, the aluminum oxidation coloring to wash out cast aluminum surface of the viscous liquid medicine, suggest that the first tank should guarantee a certain temperature to facilitate cleaning products. The second tank can adopt circulating water cleaning effect is better. (need to increase in addition to the film after electrolytic process after washing twice)

Aluminum oxide processing frosted fabric profile: frosted surface avoided polished aluminum extrusions in architectural decoration exists in certain environment, conditions will form the interference of light, it's like brocade and soft surface, is very popular with the market, but the existing grinding material must overcome sand uneven surface, and can see the shortage of the die lines.
