氰根是一种剧毒性离子,即使浓度很低,也能造成中毒事故。且氰氢酸易挥发,能和一些金属化合生成溶于水的盐,因此容易造成环境污染。氰化镀锌是近百年来一直沿用的方法。镀锌在电镀中约占60%左右,使用氰化物这一材料所占比例在百分之九十五以上。为了彻底消除污染,我们进行无氰电镀的工艺研究,经过反复试验和实践,在不到一年的时 Cyanide is a highly toxic ion that can cause poisoning even at very low concentrations. Hydrochloric acid and volatile, and some metal can be dissolved into water salt, so easily lead to environmental pollution. Cyanide zinc plating has been in use for nearly a hundred years. Galvanization in the plating accounts for about 60%, the use of cyanide material accounted for more than 95%. In order to completely eliminate the pollution, we conducted cyanide-free plating process research, after repeated testing and practice, in less than a year
