Anodizing of parts
During the anodizing process, specialists perform preliminary mechanical processing of the aluminum profile, during which pressing defects (including scratches, stripes, marks) are smoothed out and the most matte, uniform surface is obtained.
Depending on the required surface quality of the finished metal parts, they are processed with a shot stream or brushes made of stainless steel (grinding). In the first case, a more uniform and matte surface is obtained, in the second, the effect of a "combed" coating is achieved.
During treatment in a degreasing bath, surface contamination of the metal profile, oils and fats are removed.
aluminum oxide, which was formed under the natural chinese overseas america data of the environment, is removed
Initial corrosion spots and small abrasions are etched away
Anodizing results in optical alignment of the metal surface.
After etching, all surface sludge is removed in the bleaching bath. The surface is now ready for oxidation (or anodizing process).
Then, under the influence of current (electric), a regular anode film is grown, the thickness of which is 15-20 microns. The film grows inward and on the surface. Due to this, corrosion protection and durability of the coating are achieved.
The grown anode film has a porous structure. It becomes solid after passing through a compaction bath containing hot water: the pores close.
To create a high-quality colored film (color anodizing), the aluminum profile is passed through a painting bath before the sealing bath. As a result, the porous anodized film acquires the required color.
Various requirements are imposed on the final quality of the processed profile surface, therefore the following is produced:
