3 factors affecting polishing of the aluminum die-casting surface

1. The aluminum content of aluminum. For general mechanical polishing, the hardness is already hard enough. Regardless of the internal composition, it can polish at will. However, if chemical polishing use in aluminum surface treatment, the aluminum content of aluminum must reach a certain ratio before chemical polishing. Determine the required aluminum content based on the concentration of the solution.

   
   

2. There are impurities on the outside of aluminum. In chemical polishing, since the chemical solution will react with impurity, it is usually not allowed on the surface of the aluminum material, thereby affecting the polishing effect. If there are impurities, chemical polishing cannot use, or the treatment of removing an impurity such as mechanical polishing should perform first, and then chemical polishing should use.

   
   

3. The temperature of the chemical polishing liquid. As we all know, chemical polishing solution requirements are strict, and the effect will be good. If these parameters are valid, you need to prepare. But the temperature is not easy to control, and it will also affect the effect because the temperatures will change when a chemical reaction occurs.
