PLATING SOLUTION FOR ELECTRO-GALVANIZED STEEL SHEET MANUFACTURING METHOD FOR ELECTRO-GALVANIZED STEEL SHEET USING THE SAME AND ELECTRO-GALVANIZED STEEL SHEET PREPARED USING THE SAME

摘要

According to the present invention, disclosed are a plating solution for an electro-galvanized steel sheet, a method for manufacturing an electro-galvanized steel sheet using the same, and an electro-galvanized steel sheet manufactured using the same. In one embodiment, the plating solution for an electro-galvanized steel sheet includes: 20-40g/l of zinc sulfate (ZnSO_4); 20-40 g/l of nickel sulfate (NiSO_4); 8-30 g/l of cobalt sulfate (CoSO_4); 10-15 g/l of boric acid (HBO_3); 15-35 g/l of sodium sulfate (Na_2SO_4); and 10-50 g/l of sulfuric acid (H_2SO_4). The present invention provides excellent corrosion resistance and rust resistance.
