Operating principle:
Putting the workpieces and corresponding electrode into the water-soluble paint and connecting the electricity supply. The resin and fillers in the paint will separate out equably on the surfaces of the workpieces and deposit to form water-fast paint films on the physical and chemical effects of electric fields.
