在Cr/Ni和Ni/Cu/Ni/Cr等防护-装饰性多层电镀体系中,很多单位采用光亮镀镍为中间镀层,代替抛光工序,节约电镀及抛光材料,实现电镀一步法生产,因此光亮镀镍得到了普遍地重视和应用。光亮镀镍溶液在使用一段时间后,因挂具、零件带入少量其他溶液的污染;零件落入镀槽中而未及时捞出;添加的化工原料纯度不够;有机添加剂的分解等,均会造成镀液中铜、铁铬等金属杂质和有机分解物质的积累。当杂质
In Cr / Ni and Ni / Cu / Ni / Cr protective - decorative multi-layer plating system, many units using bright nickel plating as the intermediate coating, instead of polishing process, saving electroplating and polishing materials to achieve one-step electroplating production, therefore Bright nickel plating has been generally valued and applied. Bright nickel plating solution after use for a period of time, due to hanger, parts into a small amount of other pollution; parts fall into the plating tank without timely remove; added chemical raw material purity is not enough; decomposition of organic additives, will Resulting in the bath of copper, iron chromium and other metal impurities and the decomposition of organic matter accumulation. When impurities
