A Bit of Blaze New Trails from Practice

本文介绍了用亚硫酸氢钠快速去除镀镍液中的硝酸根,硫化钠去除镀锡液中的铜杂质,镀铬液中三价铬的控制,无添加剂低温镀装饰铬,氯化物镀锌中丁炔二醇的妙用,中酸中铜的光亮镀铜,镀锌钝化的改进等技术问题,这些源于实践的点滴创新对电镀工作者大有裨益。

The article has introduced elimination NO3^- in nickel- plating liquid by NaHSO3, elimination Cu^2 ＋ in tinplating liquid by Na2S, control of Cr^3＋ in chromizing liquid, decorative chromizing without additive by low temperature, magical effect of 2 - butyne - 1,4 - diol for zinc - plating by chloride, bright copperizing of medium content of acidity and copper salt, improvement of passivation of zinc - plating, and so on.
