1. Mechanical method: sandblasting finishing, shot peening finishing, burying, scouring and polishing with glass or ceramic particles. It is possible to mechanically erase the contamination of data that has been removed, polished or buried. All kinds of pollution, especially foreign iron particles, can be a source of scavenging, especially in humid environments. Therefore, the mechanical finishing appearance is better should be standardized finishing under dry conditions. Aluminum profile table using mechanical method can only finish the appearance, can not change the corrosion resistance of the data itself. Therefore, it is advocated that after mechanical finishing, the polishing equipment is polished from the beginning, and the polishing film is closed.
2. Chemical methods: pickling cream or spray auxiliary agent on aluminum profile worktable corrosion parts clean to make it from scratch passivation form chromium oxide film to restore corrosion resistance from scratch, after pickling, in order to remove all pollutants and acid residues, with water for appropriate scouring is very important. After all disposal, use polishing equipment to polish from scratch, and then use polishing film to close. For some of the slight rust spot can also be used 1:1 gasoline, oil mixture with clean cloth to wipe the rust spot can be.
