HL-5 B Type Potassium Chloride Zinc Electro-plating High Temperature Carrier

  Potassium chloride zinc electro-plating high temperature carrier

HL-5 Potassium chloride zinc electro-plating high temperature carrier

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

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

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

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

5.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.

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

7.Less decomposition, clear plating solution

HL-5 is a low foaming non-ionic surfactant with a high cloud point. In acid zinc baths, it helps to solve the brightener and improves the deposition at high current density.
Packing ：25kg/drum or 200kg/drum, stored in cool and dry place.

1.Anode zinc plate

The purity of the anode zinc plate has a great influence on the plating solution in the production. The inferior zinc plate often contains impurities such as iron, copper and lead, resulting in dark coating, slow deposition rate of the coating and mist phenomenon after passivation. It is recommended to use 0# standard zinc plate in potassium chloride galvanizing, and the quality of zinc plate shall not be lower than 1# zinc standard in GB470-64 standard.

2.Current

Current is too high, coating rough, foaming, peeling, tank temperature rise.

The current is too low, deep plating ability is poor or no coating. Generally, 0.5-3A/dm2 is appropriate.

3.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.

4.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.
