NICKEL FLASH PLATING SOLUTIONS, ZINC-ELECTROPLATED STEEL SHEET AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A nickel flash plating solution, a zinc-electroplated steel sheet, and a manufacturing method thereof are provided to prevent concentration and precipitate of iron flowing in the plating solution. CONSTITUTION: A nickel flash plating solution comprises nickel salt, conductive assistant agent, complexing agent, and surface improving agent. The conductive assistant agent enhances the conductivity of the plating solution. The complexing agent is used for the stabilization of the plating solution and is combined with iron ion included in plating solution to help the vacancy of the iron ion. The surface improving agent flattens the lowest plating film.
