1. One of the main advantages of cyanide-free alkaline copper plating technology is that it does not use highly toxic cyanide.
2. From an environmental point of view, cyanide-free plating is not only environmentally friendly, but also superior in some aspects.
3. Cyanide-free plating often uses strong complexing agents such as HEDP instead of cyanide, which reduces the use of highly toxic substances but also brings new challenges.
4. Compared to cyanide, these alternatives are more difficult to treat the effluent and less degradable to the environment.
5. In addition, the stability of cyanide-free plating systems is relatively poor, which requires more optimisation and adjustment in practical applications.
