Acid Potassium Chloride Zinc Electroplating Softener
Softener Solubilizing main brightener, auxiliary brightening effect, increase the coating thickness in low area, improve the depth capacity of the bath, reduce the surface tension of the bath, on the cathode surface wetting effect. The content in the bath is 25ml/L - 30ml/L The coating brittleness increases and passivation quality is affected by high content. The content is too low, the bright effect is not good, the coating is easy to flower, stay in the air and change color quickly.

The coating has white mist
|
Effect of organic impurities Poor cleaning after plating |
Activated carbon filtration Change the cleaning water |
|
The coating blackening after acid dipping |
Iron impurity Copper impurity |
Hydrogen peroxide treatment and filtration Treat with zinc powder |
|
Roller holes appear in the coating
|
Lack of softener Iron impurity Excessive current Lower zinc Over loading of work
|
Softener supplement Hydrogen peroxide treatment and filtration Lower total current Zinc chloride supplement Reduced loading |
