Acid Potassium Chloride Zinc Electroplating Brightener

In the production practice, as long as the additive selection is appropriate, the content of zinc chloride can be increased, even if the current density is increased, the coating will not appear burning phenomenon on the surface of the plating, so as to ensure the quality of the coating and improve the output.

Description

For the matrix metal that is difficult to electroplate, such as cast iron, the zinc content should be upper limit to increase the cathode limit current density, and the zinc content should be lower limit in summer.

The concentration of zinc chloride can vary in the range of 40-80g/L, in principle, the content of hanging plating is lower than that of rolling plating. If there is a hanging bath with moving cathode, the content of zinc chloride should be 45-60g/L. If there is no cathode moving device, the content of zinc chloride should be 60-80g/L. According to experience, the loss of 1 ton parts per plating is 4-5 kg.
