ACID ETCHING LIQUID ELECTROLYSIS RECYCLING SYSTEM

The equipment through the process route of ion membrane electrolysis to achieve the recycling of etching liquid and effectively convert copper ions into metal copper. The etching solution in the etching line is circulated into the electrolytic cell.

Basicity Etching liquid extraction and electrolytic recycling system

By mixing the imported extractant agent with the etching waste liquid, the copper ions are adsorbed on the extracted oil, and then separated from the oil phase through the liquid phase. The oil phase (extracted oil) reacts with sulfuric acid to form copper sulfate, and finally enter the electrolytic cell.

Basicity Etching direct electrolytic recycling system

The principle of alkaline etching by direct electrolysis.Through direct electrolysis technology, the copper ions in the waste liquid are precipitated on the cathode plate. After electrolysis, the regeneration liquid is returned to the production line by supplementing ammonia and etched salt and then returned to the production line for recycling.
