摘要
针对塑料电镀粗化工序三价铬电解去除效果不佳的问题,采用电解实验的方法对三价铬电解过程进行了研究。结果表明:在30~100 g/L的硫酸电解液中,当温度为50~70℃,电压为5~10 V时,每3~4 h更新电解液,能有效地降低三价铬的含量。
In order to solve the poor removal effect of trivalent chromium in roughening process of plastic electroplating,the electrolysis process of trivalent chromium was studied by electrolysis experiment.The results showed that when the temperature was 50-70 ℃ and the voltage was 5-10 V,the content of trivalent chromium could be effectively reduced by renewing the electrolyte every 3-4 h.
