| titleOfInvention | HDI plate etching liquid electrolytic regeneration device |
| abstract | This utility model relates to etching waste liquid processing technology field, specifically, relate to a kind of HDI plate etching liquid electrolytic regeneration device, including electrolysis bath (1), being provided with negative electrode (2) and anode (3) in this electrolysis bath, described negative electrode (2) is separated by ceramic diaphragm (4) with anode (3), and cathode design increases the structure of electrode area, in catholyte, add copper powder, graphite powder or other conductive fine powders simultaneously, use air pump to blast air agitation catholyte.In electrolytic process, in catholyte, conductive fine powder is with negative electrode collision process, and copper ion is reduced into elemental copper on conductive fine powder, it is achieved efficiently decopper(ing), especially gradually decreases when electrolyte copper ion concentration, still has high current efficiency, and liberation of hydrogen side reaction is few；Meanwhile, anode generation oxidation reaction, produce H + And precipitated oxygen, along with reaction is carried out, etching waste liquid acidity is gradually recovered, and after filtration, electrolyte is recyclable for wiring board etching reaction. |
