Acid Potassium Chloride Zinc Electroplating Brightener
Acid potassium chloride zinc electroplating brightener Electroplating is in the electrolyte containing some metal ions, will be plated workpiece as the cathode, through a certain waveform of low-voltage direct current, so that metal ions get electrons, constantly deposited in the cathode for metal processing process. So as to prevent corrosion, improve wear resistance, electrical conductivity, reflective and improve the appearance of the role.

USE: 1. Metal surface treatment electro-galvanized
2. Galvanized standard parts, such as screw, nuts, and bolts
3. Metal accessories and metal fittings need to be galvanized
4. Electric galvanizing parts color has silver white, blue white, and color
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.
