Process for producing one-side electrogalvanized steel sheet. |
摘要 |
<p>A one-side electrogalvanized steel sheet with a distinguished susceptibility to a phosphate salt treatment and a distinguished appearance on the non-electrogalvanized side is produced by subjecting the non-electrogalvanized side of a steel sheet after one-side electrogalvanization in a galvanizing bath to an electrolytic peeling treatment using the non-electrogalvanized side of the one-side electrogalvanized steel sheet as an anode in an electrolytic peeling treatment bath containing 5 to 30% by weight of sodium sulfate as an electroconductive agent and at least 0.1% by weight of boric acid as a pH-controlling agent at a pH adjusted to a range of 5.0 to less than 9.0 as a posttreatment of the non-electrogalvanized side.</p> |
