The Cleaning Steps Of Oxide Surface Treatment Aluminum Parts

The original physical appearance of aluminum cannot be restored after oxidation. Because the oxidation reaction that occurs is intermolecular, the metal bond interaction cannot be restored, and it can only be reduced and returned to the furnace.

The Cleaning Steps Of Oxide Surface Treatment Aluminum Parts

The cleaning steps of aluminum surface oxidation treatment:

  • A. Water after degreasing (degreasing) of aluminum surface treatment: MIL-A-8625 should be equipped with two water washes. The purpose of aluminum oxidation coloring is to clean the residual chemical solution (or acid or alkali, if added to the degreasing agent). For solvent-based emulsifiers, cleaning is more important.) or greasy dirt. Prevent the subsequent tank liquid from being brought into the tank liquid to affect the stability of the tank liquid and prevent the product from being oily and produce defective products. The two water washes can not be used for overflow, and it can be replaced regularly depending on the workload.
  • B. Washing after alkaline etching: At least three washings are required. The purpose is to wash away the viscous alkaline etching tank liquid film remaining on the surface of the aluminum after alkali etching. Because it is difficult to clean, it is recommended that the water in the first sink should be replaced as much as possible to ensure a certain temperature and alkalinity, which is beneficial to cleaning the product . If there are conditions in the latter two tanks, the mixing effect can be better. The two water washes can not be used for overflow, and it can be replaced regularly depending on the workload.
  • C. Water washing after chemical (electrolytic) polishing: Two water washings are sufficient. The purpose of aluminum oxidation coloring is to wash away the sticky chemical polishing liquid on the surface of aluminum. It is recommended that the first sink should be kept at a certain temperature to facilitate product cleaning. . The second water tank can be cleaned with circulating water for better cleaning effect. (After electrolysis, the membrane removal process needs to be added and then washed twice with water)

Aluminum oxidation treatment matte fabric profile: matte surface aluminum profile avoids the shortcomings of bright aluminum alloy profile that will cause light interference in architectural decoration under certain environment and conditions. Its surface is as delicate and soft as brocade, which is very popular in the market. Favored, but the existing frosted materials must overcome the uneven surface sand and can see the lack of pattern patterns.
