摘要
介绍采用硫锌-30或硫锌-40为光亮添加剂的硫酸盐电镀锌的生产工艺参数,镀液各组分的作用,镀液的维护,常见的故障处理和光亮添加剂在使用过程中的注意事项。给出光亮镀锌工艺参数:硫酸锌为450~550 g/L,硼酸为20~30 g/L,pH为3.0~5.0,镀液温度10~60℃,光亮剂为16~20 mL/L,阴极电流密度10~45 A/dm2。和传统硫酸盐单盐镀锌工艺相比,光亮电镀锌工艺具有成分简单、稳定易维护、沉积速度快、电耗低,镀层细致光亮,耐蚀能力强等优点,适合生产表面光洁度要求高的商品钢丝。
To introduce the sulfate bethanizing's productive technology parameter with bright additive of zinc sulfate - 30 or zinc sulfate -40, the component of different plating sulfate, the maintance of plating bath, usual recovery processing, and attention points of bright additive during using. The technology parameter of bright galvanization is given : zinc sulfate is 450 ~550 g/L, boric acid is 20 -30 g/L, pH is 3.0 -5.0, plating bath temperature is 10 -60 ~C , brightener is 16 -20 mL/L, cathode-current density is 10 -45 A/dm:. Comparing with traditional sulfate simple salt galvanization technology, bright bethanizing technology has more advantages: simple composition, stable and easy to maintain, hign deposition rate, low power consumption, delicate and bright coating coat, and high anti-corrosion performance, which is more suitable for producing high requirement wire with good glassy surface.
