Process characteristics of cyanide free alkali copper
Cyanide free copper plating is an environmental protection processing method, which can replace the traditional cyanide copper plating process and bright copper plating process. It is applicable to any metal substrate: pure copper, copper alloy, iron, stainless steel, zinc alloy die casting, aluminum, aluminum alloy workpiece and other substrates. Hanging or rolling plating can be used.
The process characteristics of cyanide free alkali copper mainly include:
1: the plating solution does not contain cyanide, phosphorus, strong chelator, and the wastewater treatment is simple.
2: the process adopts the form of monovalent copper, and the stacking efficiency is twice that of divalent copper.
3: the anode dissolves well and the copper ion will not decrease.
4: the coating crystal is fine and smooth, semi bright
5: the plating solution has good dispersion ability and depth ability, which is superior to cyanide copper plating.
6: suitable for hanging and rolling plating of iron, copper, zinc and aluminum alloy substrates.
