Description

Potassium chloride type weakly acidic galvanizing electrolyte is a kind of cyanide-free galvanizing process developed rapidly in recent years, which is referred to as potassium salt galvanizing.

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.

Our main products are chemical additives, which used in manufacture zinc electroplating bath, for improve the brightness of galvanized layer on metal surface.

Acid potassium chloride zinc plating brightener, which used in manufacture zinc electroplating bath, for improve the brightness of galvanized layer on metal surface.

Zinc chloride provides zinc ions. When the content of ZnCl12 is set to the upper limit, the cathode current density can be improved and the deposition rate of the coating can be improved, but the dispersion ability and covering ability become worse. When the content of ZnCl12 is set to the lower limit, the dispersion ability can be improved, the loss of the plating parts taking out liquid and the cost of tank fitting and wastewater treatment can be reduced. When the content of ZnCl12 is too low, the concentration polarization will be large, resulting in low current opening, which will narrow the bright area of the plating, decrease the cathode current density accordingly, slow down the deposition rate, and prone to charring phenomenon in the high current density area of the plating.
