Title:
METHOD AND DEVICE FOR FEEDING METAL ION IN ELECTROPLATING AND METHOD FOR FEEDING ZINC ION IN GALVANIZING
Document Type and Number:
Japanese Patent JPH03126898
Kind Code:
A
Abstract:
PURPOSE:To accelerate the dissolution of a metal for plating and to feed a plating soln. having an increased concn. of metal ions into a plating vessel by passing a circulating plating soln. having a lowered concn. of metal ions through a vessel packed with electroforming metal chips. CONSTITUTION:A plating soln. having a lowered concn. of metal ions in a plating vessel 1 is sent from a soln. vessel 6b to a dissolving device 2 fitted with a vessel packed with electroforming chips 4 of a metal such as Zn. The plating soln is introduced into the packed vessel from its bottom through a perforated plate 5 and a sludge sedimentation tank 3 and a An is dissolved to increase the concn. of metal ions in the plating soln. This plating soln. having the increased concn. of metal ions is introduced into a circulation tank 6 and fed into the plating vessel or other plating vessel.
