5.Solution preparation

Zinc plating solution:

ZnCl₂ 30-70 g/L
KCl 200-260 g/L
H₃BO₃ 25-35 g/L
Wake up agent 16-25 ml/L
Brightening agent 0-1 m1/L

6.Common faults and solutions

Coating blooming (fog)
Possible causes Solutions
1. Pre treatment with oil 1. Strengthen oil removal
2. Poor post-treatment processing 2. Improvement
3. Excessive organic and metal impurities 3. Major treatment
4. Excessive brightening agent 4. Electrolysis at low pH
5. Less boric acid 5. Supplement
6. Aging of the dipping liquid 6. Replacement
7. insufficient anode area 7. Adding multiple anodes
