Title: SURFACE TREATMENT METHOD FOR ELECTROPLATING CONDUCTOR ROLL AND ELECTROPLATING CONDUCTOR ROLL
Abstract:
[Problem] To limit adhesion of foreign matter stemming from plating liquid, metal stemming from the plated steel sheet and oxides of the metal to the surface of a conductor roll. [Solution] A surface treatment method for surface-treating the roll surface of an electroplating conductor roll characterized in that: the surface treatment liquid is a surface treatment solution in which graphite has been dispersed in a mixed solution made of an aqueous aluminum phosphate solution and colloidal silica; and the surface treatment liquid, in which concentrations have been adjusted such that when the surface treatment liquid is 100 mass%, the aluminum phosphate content is 3 mass% to 14 mass%, the silica content is 7 mass% to 37 mass%, and the graphite content is at least 4 mass%, is supplied to the roll surface and baked.
