摘要
研究了铁杂质对酸性滚镀锌镀液的影响和处理方法。向镀液中加入双氧水0.05mL/L,pH值在4.5～5.3范围内,铁杂质的质量浓度降低10.2～17.3mg/L,且在pH值较低的条件下,处理铁杂质的效果较好。制定了宽温酸性滚镀锌工艺:氯化锌45～55g/L,氯化钾200～230g/L,硼酸30～35g/L,401主光剂1mL/L,401辅光剂30mL/L,pH值4.5～5.5,5.5～6.5V,15～45℃,40～120min。
The effects of iron impurity on acidic zinc barrel plating bath and methods for treating iron impurity were studied. When 0.05 mL/L hydrogen peroxide was added to the plating bath, the mass concentration of the iron impurity decreased 10.2 -17.3 mg/L in pH range from 4.5 to 5.3, and the treatment result was better when pH was lower. A wide temperature range acidic barrel zinc plating process was made： zinc chloride 45-55 g/L, potassium chloride 200- 230 g/L, boric acid 30-35 g/L, 401 main brightener 1 mL/L, 401 accessorial brightener 30 mL/L, pH value 4. 5-5. 5, voltage 5. 5-6. 5 V, temperature 15-45 ℃, processing time 40-120 min.
