Electroplating Zinc Acid Potassium Chloride Brightener

Electroplating is the use of electrolytic way to deposit metal or alloy on the workpiece surface, in order to form a uniform, dense, good bonding metal layer process. Electroplating is in the electrolyte containing some metal ions, will be plated workpiece as the cathode, through a certain waveform of low-voltage direct current, so that metal ions get electrons, constantly deposited in the cathode for metal processing process. So as to prevent corrosion, improve wear resistance, electrical conductivity, reflective and improve the appearance of the role.

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.
