Five methods for extruded aluminum profile enclosure surface treatment,
1.Anodizing, removing aluminum oxide from the surface of extruded aluminum profile enclosure, and effectively polishing them.
2.Electrolytic polishing in which electrolytic polishing is used as an anode, insoluble metal as a cathode is immersed in an electrolytic cell,
and the anodic alumina is dissolved by direct current.
The alumina disappears from the shell of the extruded aluminum profile enclosure and restores its luster.
3.Chemical polishing can be used as a pretreatment process for protective decorative electroplating,
or as a pretreatment process for chemical film formation such as phosphating and bluing.
If the water solution is used to prevent rust and passivation before spraying, the alumina on the surface of the extruded aluminum profile enclosure shell can be eliminated.
4.Coloring after Anodizing in the electrolytic reaction, form a variety of colors on the oxide film and then coloring,
this could be set according to your requirements.
The above four polishing methods are commonly used,also relatively cheap, operable,
can effectively remove aluminum oxide on the surface of the extruded aluminum profile enclosure, achieve polishing effect,
restore the original color of the extruded aluminum profile enclosure.
