How do industrial aluminum profiles achieve a bright surface? This requires acid etching. The acid etching treatment technology of industrial aluminum profile is to transform the traditional acid etching bath, adding sand polishing tank and plane polishing tank to perform bright treatment on the acid etching material, so this process is also called bright acid etching technology.
 
Bright acid etching technology is composed of four processes: degreasing and dewaxing, brightening and acid etching, sand surface polishing and plane polishing. These four processes cooperate with each other and are indispensable. It is a perfect set of industrial aluminum profile brightening technology.

The main points of bright acid etching technology operation:
 
1. Reminder for slot setting: there is no water washing tank between the brightening acid etching tank and the sand polishing tank
 
2. Slot function description: degreasing and dewaxing tank, brightening and acid etching tank, sand polishing tank, flat polishing tank, anodizing tank
 
3. Description of process operation method: the industrial aluminum profile is degreased after 1-4min, after one wash, it enters the brightening and acid etching tank, after 4-12min, it directly enters the sand surface polishing tank, and after 3-9min, it undergoes another wash Enter the flat polishing tank, wait for 3-7min, after two water washings, and finally perform anodizing treatment.
