Failing to restore its original physical appearance after oxidation. Because the oxidation reaction is between the molecules, can not restore the interaction between the metal bond, can only be reduced after the furnace.

Cleaning steps of aluminum surface oxidation treatment:

A. water washing after oil removal (degreasing) of aluminum surface treatment: mil-a-8625 should be provided with two washes. The purpose of aluminum oxidation and coloring is to wash the residual liquid of the product (or acid or alkali, cleaning is more important if solvent emulsifier is added in the oil removal agent). Or oil. Prevent the product from being carried into the following tank to affect the stability of the tank and prevent the product from being contaminated with oil and producing defective products. The two times of washing can not be used for overflow, according to the workload of regular replacement on the line.

B. Washing after alkali corrosion: at least three times of washing are required. The purpose is to wash away the thick and sticky alkali etched bath film left on the aluminum surface after alkali etching. The back two sinks have conditions, can increase the stirring effect is better. The two times of washing can not be used for overflow, according to the workload of regular replacement on the line.

C. Washing after chemical (electrolytic) polishing: two times of washing is enough. The purpose of aluminum oxidation and coloring is to wash away the sticky chemical polishing liquid on the surface of aluminum. The second flume can be better cleaned by circulating water. (add film removal process after electrolysis and then wash twice)

Aluminium oxide processing frosted fabric profile: frosted surface aluminum avoids the polished aluminum alloy profiles 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.
