Description

It is characterized by simple electrolyte composition, stable electrolyte, fine coating, bright, high current efficiency, wide operating temperature range (5 ~ 60℃), simple wastewater treatment. The chemical dissolution of the anode in the electrolytic cell leads to the increase of the concentration of main salt ions in the electrolyte.
