Redissolution manner and its device null of precipitation nickel in plated

摘要

PURPOSE: To redissolve nickel deposited inks a plating liquid. ;CONSTITUTION: In a continuous Zn-Ni electroplating device using an insoluble anode, there are provided a solid-liquid separating means 10 for separating nickel deposited into a plating liquid from inside a circulating path constituted of piping 6, 7, 8 by which a dissolving tank 1 where metal zinc is dissolved in the plating liquid to replenish zinc ions and a plating liquid circulating tank 2 are connected, a redissolving tank 12 for redissolving the separated, deposited nickel, and a mixing means 15 for blowing gaseous oxygen through the plating liquid in the redissolving tank 12.;COPYRIGHT: (C)1994,JPO
