Electrolysis column, electrolysis impurity removal device and impurity removal method for nickel plating liquid electrolysis impurity removal

Abstract

The invention discloses an electrolysis column, electrolysis impurity removal device and impurity removal method for nickel plating liquid electrolysis impurity removal. The electrolysis column comprises a shell, a cathode and an anode. The cathode and the anode are arranged in the shell. The cathode comprises a base material. The base material is plastic of a porous mesh-shaped structure. The surface of the plastic is coated with an electric conduction adhesive layer. The surface of the electric conduction adhesive layer is electroplated with a metal layer. The electrolysis impurity removal device comprises a water pump, an electric controller, an electrolytic bath and a purification tank. The electrolysis column is detachably connected in the electrolytic bath. The input end of the waterpump communicates with an electroplating tank. The output end of the water pump communicates with a water inlet of the electrolysis column. The cathode and the anode of the electrolysis column are both electrically connected with the electric controller. The device further comprises the purification tank. The electrolytic bath is provided with an overflow opening communicating with the purification tank. The purification tank is provided with a water outlet. The water outlet communicates with the electroplating tank. The impurity removal method includes the step of electrolysis impurity removal and the step of impurity recycling and has the characteristics of being simple, feasible and good in impurity removal effect.

Description

technical field [0001] The invention relates to the technical field of impurity removal in electroplating solution, in particular to an electrolytic column for electrolytic removal of impurities in nickel plating solution, an electrolytic removal of impurities and a method for removing impurities. Background technique [0002] In the electroplating nickel process, whether it is electroplating dark nickel, semi-gloss nickel, or bright nickel, satin nickel and other plating types, some metal impurities such as copper, lead, iron, zinc, etc. will be brought in, and the content of impurities in the nickel plating solution is It will directly affect the quality and stability of the coating, especially copper ions, which directly affect the brightness and compactness of the coating, so it is particularly important to remove impurities from the nickel plating solution. Existing impurity removal methods for nickel plating solution include chemical impurity removal method and electro...
