| 摘 要： | 对一次由镀镍除锌剂引起的电镀装饰铬故障进行了分析,并提出了处理方法。在镀铜、镍和装饰铬的过程中,镀镍槽中过量的除锌剂及其分解产物会引起镀铬层发雾。向镀镍液中加30%的双氧水0.3 mL/L,并加0.5 g/L活性炭吸附,可以消除它们的不良影响。后用电解法去除镀镍溶液中的锌杂质。用该方法处理后,排除了故障。

| Abstract: | A decorative chromium plating malfunction caused by zinc suppressant was analyzed,and the treatment methods were proposed.Production practice indicates that during the technology processes of copper plating,nickel plating,and decorative chromium plating,the superfluous zinc suppressant and its decomposition products in a nickel plating bath is the impurities to cause the followed chromium deposits to become dull.The impurities can be removed by adding 0.3 mL/L of aqueous hydrogen peroxide solution which con... |
