无氰镀锌代替剧毒的氰化钠镀锌,不但从根本上解决了环境保护和安全问题,而且避免了大量氰化钠进口,国内很多单位都在研究并已陆续采用。我厂在无氰镀锌方面的贡献是找到了很好的添加剂EQD—3,以EQD—3为添加剂的碱性无氰镀锌同国内情况比,成份最
Cyanide-free zinc plating instead of highly toxic sodium cyanide zinc, not only fundamentally solve the environmental protection and safety issues, but also to avoid a large number of imports of sodium cyanide, many units are being studied and have been gradually adopted. The contribution of our plant in cyanide-free zinc plating is to find a good additive EQD-3, basic cyanide-free zinc plating with EQD-3 as additive
