Acid Potassium Chloride Zinc Electroplating Brightener

Additives play an important role in plating solution. In general, additives are added according to KA.h consumption. If the proportion is out of proportion, add it according to the bath volume after adjusting by hull bath experiment.

Without additive plating solution, the coating is gray and rough, and the range of cathode current density is very small.

After adding appropriate amount of additives, the coating can be fine and bright, the current density is expanded, the dispersion ability and covering ability are improved, too high additives will cause brittleness of the coating, passivation film fall off and color change.

The general total amount should be controlled within the range of 25-30ml/L.

Brightener

The main brightener can produce remarkable brightening and leveling effect.

If the content is too high, the coating in the low current density area will become thinner, and the bottom will be exposed after passivation, which will easily lead to increased brittleness of the coating and affect the passivation quality.

The content is too low, the coating bright leveling effect is not good. The content in the bath is maintained at 0.8-2ml/L.

Common failures and processing method

The coating has high brightness, low brittleness, turbidity point of the bath can reach more than 80℃, and bright coating can be plated at 65℃. Its comprehensive performance can be completely comparable with similar foreign products, characteristics are as follows:

1. The bath does not contain ammonium, the wastewater is not polluted and easy to treat.

2. The coating is bright, suitable for low chromium passivation.

3. Adaptable to all kinds of basic materials, such as carbon steel, penetrant steel, cast iron, zinc pressure casting parts can be plated with bright zinc layer.

4. Coating brittleness is small, suitable for thicker zinc plating layer.

5. Additive consumption is low, plating solution maintenance is easy, conducive to reducing production costs.

6. The bath foam is low, both barrel and rack plating can be used.

7. Bath temperature range is wide.
