Cleaning steps for aluminum surface oxidation treatment:
 |  |
A. Aluminum surface treatment Degreased (degreased) water sputum: should have two water washing, aluminum oxidation coloring purpose is to wash the product residue of the liquid (or acid or alkali, if the solvent remover added solvent emulsifier Cleaning is more important.) Or oily. Preventing the entrainment from entering the subsequent bath fluid affects the stability of the bath and prevents the product from being contaminated with oil to cause defective products. The two water washes can be used without overflow, and it is OK to change the workload according to the workload.
B. Water washing after alkali etching: At least three water washings are required. The purpose is to wash away the thick alkali etching tank liquid film remaining on the surface of the alkali-etched aluminum. Because it is difficult to clean, it is recommended to reduce the number of replacements in a water tank to ensure a certain temperature and alkalinity, which is beneficial to cleaning products. . If there are conditions in the back two tanks, the aluminum profile manufacturer can increase the mixing effect better. The two water washes can be used without overflow, and it is OK to change the workload according to the workload.
C. Chemical (electrolytic) polishing after washing: It can be washed twice. The purpose of aluminum oxidation coloring is to wash away the viscous liquid of the aluminum surface. It is recommended that the first tank should have a certain temperature to facilitate product cleaning. . The second sink can be washed with circulating water for better results. (After electrolysis, it is necessary to increase the membrane removal process and then wash it twice)
Aluminium oxidation treatment of frosted fabric profiles: frosted aluminum profiles avoid the disadvantages of bright aluminum alloy profiles in the construction of decorative environment, under the conditions of light interference, its surface is as delicate and soft as brocade, very popular in the market Favorable, but the existing abrasive materials must overcome the unevenness of the surface sand and can see the shortage of the pattern.
