我厂自生产摩托车以来,积压了不少的不合格镀镍零件,为修复这批零件我们采用了电化学法与化学法退除然后再重新电镀。不掌握,不仅浪费大量的化工原材料,而且如不掌握好,还会造成大量的报废,另外,退除工作严重污染环境。给操作者带来了危害。我们查阐了有关资料,做了许多实验,从实践 I plant since the production of motorcycles, the backlog of a lot of unqualified nickel-plated parts, to repair these parts we use the electrochemical method and chemical method to remove and then re-plating. Not mastered, not only waste a lot of chemical raw materials, and if not mastered, will result in a large number of scrapped, in addition, the removal of serious pollution of the environment. Hazard to the operator. We examined the information, did a lot of experiments, from practice
