Sulfate Acid Zinc Plating for Thin Steel Sheet
1. Plating is smooth in silver, and good adhesion with the coating film.
2. Plating with toughness, excellent ductility, zinc plating does not crack peeling for steel deep processing.
3. Cathode current density permitted value is high, when the operating speed up to 0.5~2.0m/s at 30~40℃, the density up to 70~100A/dm2.
4. With the improvement of operating speed, increasing temperature, the cathode density up to 150A/dm2.
II. Bath composition and Operation condition
