Plastic Balls Manufacturer shares how plastic surfaces are polished?
1. Electrolytic polishing: basically the same as chemical polishing, that is, by selectively dissolving tiny protrusions on the surface of the material to make the surface smooth. Compared with chemical polishing, the effect of cathode reaction can be eliminated, and the effect is better. The electrochemical polishing process is divided into two steps: the macro-leveling dissolved product diffuses into the electrolyte, the geometric roughness of the material surface decreases, Ra> 1μm; the low-light leveling anode polarization, the surface brightness increases, Ra
