Acid Potassium Chloride Zinc Electroplating Brightener

PH value When the PH value of the bath is low, the coating is bright but hydrogen precipitates out, the current efficiency is reduced, and the covering ability is decreased. High PH value, coating rough black, local gray black. Usually the PH value will rise slowly in the process of electroplating, then pay attention to adjust the PH value with dilute hydrochloric acid in time. Adjust the PH value to constantly stir, to prevent the local acidity is too high and cause the additive precipitation. General bath PH value should be controlled in the range of 4.5-5.4, with 4.8 as the best.

Description

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.
