无氰镀银新工艺在新东北电气集团的应用

Application of New Cyanide-Free Silver Plating Process in Xindongbei Electric Group

针对传统电镀银所使用的氰化物工艺,为解决剧毒氰化物对人类健康、环境造成的危害问题,设计开发了一种新型无氰镀银工艺来代替氰化镀银工艺,研究了双配位体系无氰镀银溶液、无氰浸锌溶液性能及所得镀银层性能影响。结果表明:采用双配位体系络合剂可以提高无氰镀银溶液稳定性,使各项性能达到氰化镀银指标;采用新型无氰浸锌溶液可以提高铸铝件镀银结合力;该工艺的实际应用,避免了氰化物的危害、降低了生产成本、有利于操作人员的身体健康和生命安全,属于绿色生产工艺,符合国家产业政策,极具推广价值。

Aiming at the cyanide process used in traditional silver electroplating,in order to solve the hazards of highly toxic cyanide to human health and the environment,as well as the problems in the use of cyanide electroplating solution and the recovery and treatment of waste liquid,a new type has been designed and developed.The cyanide-free silver plating process replaces the cyanide silver plating process,and the performance of the cyanide-free silver plating process on the coating has been studied.The results show that the performance of the new cyanide-free silver plating process reaches the cyanide silver plating index and is beneficial to the health and life safety of the operators.
