Acid Potassium Chloride Zinc Electroplating Brightener

In addition, we should pay attention to the quality of boric acid and prevent the interference of nitrate and other factors.

Note: The brightness of the galvanized layer caused by the lack of boric acid is not enough, and the addition of brightener is of no avail. But after the addition of boric acid, the coating is immediately bright, which is the defect caused by the poor buffering performance of the plating solution of boric acid. Therefore, the role of boric acid must not be ignored in production, and its content should be guaranteed within the process range. In daily production, when the PH value of the bath changes quickly, it indicates that the boric acid content in the bath has been low, and it needs to be added. Boric acid is only taken out of consumption. As a rule of thumb, you only need to supplement boric acid with potassium chloride. The supplement amount is 1/7 of the weight of potassium chloride, that is, for every 7 kilograms of potassium chloride, you need to also add 1 kilogram of boric acid. In addition to boric acid should be fully dissolved after adding, otherwise it can not play its due role.
