无氰碱性锌酸盐镀锌光亮剂的研究

Study on the Brightener for High Bright Zn-plating in Zincate Solution of Non-cyanide

回顾我国无氰碱性锌酸盐镀锌光亮剂20年来的发展状况;介绍一种能在无氰碱性锌酸盐镀锌体系中产生镜面似的高光亮镀锌层的光亮剂——WD90A。通过电化学方法的测试,结果表明该光亮剂的作用机理符合电镀添加剂的经典理论。

This paper reviews the development of the brightener of more than 20 years for Zn-plating zincate solution of non-cyanide in our country and introduces a new brig- htener(WD90A)which produces a kind of mirror zinc coating.The testing results show that the properties and brightening mechanism of the brightener agree with the classical theories of electroplating additives.
