Etching liquid electrolytic regeneration unit.
This is an epoch-making diaphragm unit that replaces the unglazed cylinder used in the equipment that electrolyzes and regenerates the etching solution (chromic acid / sulfuric acid) used in the pretreatment of plastic plating.
In the electrolytic regeneration equipment that uses the unglazed cylinder currently in use, dirt in the solution adheres to the unglazed cylinder and causes clogging.
As a result, the electrical resistance increases and it becomes difficult for current to flow.
Therefore, the unglazed cylinder must be maintained regularly.
It has been necessary to take out the unglazed cylinder, which may be broken if dropped, take it out of the tank, wash it, and then reattach it, which is a laborious and troublesome task.
This "etching liquid electrolytic regeneration unit" uses a polymer charged film with excellent durability, has low electrical resistance, and is stable because clogging due to resin components generated during etching is unlikely to occur. Current supply is possible.
As a result, stable control of trivalent chromium values has been achieved.
It frees you from troublesome maintenance and contributes to power cost reduction by stabilizing current efficiency.
