The utility model belongs to the technical field of purifier, concretely relates to alligatoring liquid purifier that plastics were electroplated.

Background

In recent years, plastic electroplating is widely applied to decorative electroplating of plastic parts, at present, the plastic electroplating is most widely applied to ABS plastic electroplating products, the ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B) and styrene (S), the ABS plastic is taken as electroplating-grade ABS plastic, and the content of butadiene is generally controlled to be 18-23%; the ABS plastic is coarsened by using coarsening liquid during electroplating, and the purpose of coarsening is to dissolve butadiene to form microscopic coarseness on the surface of the ABS plastic so as to ensure that a subsequent electroplated layer has good adhesive force and bonding force.

The coarsening quality directly influences the electroplating quality of the ABS plastic. Two situations can occur during the roughening process: hexavalent chromium contained in the roughening solution can generate corrosion reaction with a product to be reduced into trivalent chromium and organic matters, when the content of the trivalent chromium is accumulated to be more than 20g/L, the oxidation capability of the roughening solution is weakened, the roughening effect is seriously influenced, and the bonding force between the ABS plastic and an electroplated layer is obviously reduced; in the roughening process, impurities such as rubber particles can be dissolved from butadiene, and the roughening effect can be seriously influenced.
