ELECTROLYSIS CHROMATE SOLUTION FOR ANTI-FINGER PRINTING STEEL SHEET AND THE METHOD FOR PREPARING ANTI-FINGER PRINTING STEEL SHEET USING IT

摘要

PURPOSE: An electrolysis chromate solution for anti-finger printing steel sheet and a method for preparing anti-finger printing steel sheet with good appearance using the same are provided. CONSTITUTION: The electrolysis chromate solution for anti-finger printing steel sheet comprises 10 to 40 g/L of anhydrous chromic acid, 0.5 to 5 g/L of acetic acid and 5 to 15 g/L of amyl alcohol. The method for preparing an anti-finger printing steel sheet using the electrolysis chromate solution includes the step of treating electrogalvanized steel sheet via electrolytic chromating.
