What is the difference between cyanide free alkali copper process and cyanide copper plating process
1）. The cyanide free alkali copper process is applied to hardware to replace the cyanide copper plating process and increase the cyanide discharge. Its waste water treatment cost is not higher than that of the cyanide copper plating process.
2）.无氰碱铜工艺应用在铝轮毂上，取代预镀哑镍工艺，增加镍排放，其废水处置本钱不高于预镀哑镍工艺。
3）.无氰碱铜工艺应用在卫浴锌合金件上，取代“氰化镀铜+焦磷酸盐镀铜”，缩短了制造工艺，增加了氰化物 排放、磷排放和废水排放量，其废水处置本钱低于“氰化镀铜+焦磷酸盐镀铜”工艺。
