HL-5 A Type Acid Potassium Chloride Zinc Plating Intermediate

  HL-5 Potassium chloride zinc plating intermediate

High turbidity point: above 90 degrees, when the temperature is 10-55 degrees, the working liquid can produce normally.

1.High salt resistance: electroplating solution potassium chloride content up to 280g/L, no salting out.

2.High brightness: adapt to the secondary brightener benzylacetone or o-chlorobenzaldehyde, the combination of the two brightness is better.

3.Good coverage ability: good deep plating ability and even plating ability.

4.Wide current range: 3A current in the 25 degree hull tank, the bath is not cloudy, no burning in the high area of the test piece. Electroplating users can open large current, shorten plating time, improve production efficiency, reduce comprehensive cost.

5.The preparation of potassium chloride zinc additive with HL-5 carrier has wide technological range, stable production and convenient maintenance.

6.Less decomposition, clear 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.

A.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.

B.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.
