Process Features
:
Jiangzhehu aluminum alloy quaternary environmentally friendly zinc sinking agent is easy to operate and suitable for rack plating and barrel plating.
Does not contain chemicals.
It can produce a dense and uniform thin layer of quaternary metal zinc immersion on the aluminum surface, providing good binding force for direct copper plating, nickel plating, tin plating, and electroless nickel plating in subsequent processes.

Solution maintenance
:
The zinc precipitating agent does not require subsequent supplementation of chemicals with strong binding force and can be calculated based on specific gravity. When the concentration of the solution is in milliliters/liter, the specific gravity unit is approximately ., and the specific gravity of the solution should be maintained between . Every time the specific gravity unit is increased, ml/L of aluminum alloy cyanide-free zinc precipitation agent needs to be added
Every ml/L of Renchang quaternary zinc precipitation agent added does not require chemicals and has strong subsequent binding power and can provide a zinc content of grams/L< br/>Equipment requirements
