Bath Preparation:

1. Pour water into the tank with 50% by the volume; the chloride ion containing in the water should not less than 70 mg/L. Fill in the required copper sulfate and stirring until it is completely dissolved.

2. Put in 2g/L active carbon powder and stirring for 1 hour; then leave it still for 4 hours.

3. Pour the solution into the clean electroplating tank by the filter pump then fill in water to the water level, slowly put in concentrated sulfuric acid, stirring the solution with force due to it releases great amount of heat.

4. Cool the bath to 25 °C, analyze the containing of chloride ion in the bath, if it is insufficient, please fill in adequate HCl until the chloride ion reach to the standard.

5. Fill in the additives as listed on above, stirring until even. Under the normal condition, after electrolyze the bath by 3-5 ampere hour per liter, it can start production.

It has been widely applied in rack plating, as the based layer for button, zipper, buckle, get a shining and bright layer of copper.

Stable and easy to perate make it best-seller in domestic market.
