Acid Potassium Chloride Zinc Electroplating Brightener

Temperature

High bath temperature can increase the current density, but high temperature bath dispersion ability and coverage ability decreased, low area coating thinner, parts overall brightness decreased, coating fog. If the bath temperature is high, the additive consumption will increase, and reducing the bath temperature can reduce the consumption of brightener. When the bath temperature is too low, it shows that the additive is too much, especially when the brightener is too much, the plating parts will be burnt in the high area. Especially in winter, the first bath bath, prone to zinc burst layer, so to take a small current to extend the plating time.

Plating before treatment is not good, cleaning is not clean, the surface of iron and iron or adsorption on the surface of iron filings into the plating solution.

Parts falling into the cylinder are not salvaged in time.

Iron impurities introduced by raw materials.
