METHOD FOR PRODUCING SURFACE-TREATED STEEL SHEET, SURFACE-TREATED STEEL SHEET, AND ORGANIC RESIN COATED METAL CONTAINER |
| 摘要 |
Provided is a method for producing a surface-treated steel sheet including the step of forming a layer mainly composed of an oxygen compound containing Al onto a tin-plated steel sheet by conducting cathode electrolytic treatment to the tin-plated steel sheet using an electrolytic treatment solution containing Al ions and nitrate ions. For the electrolytic treatment solution, an electrolytic treatment solution not containing F ions and where the amount of nitrate ions contained is 11,500 to 25,000 ppm by weight is used. |

1. A method for producing a surface-treated steel sheet comprising:
forming a layer mainly composed of an oxygen compound containing Al onto a tin-plated steel sheet by conducting cathode electrolytic treatment using an electrolytic treatment solution containing an Al ion and nitrate ion to the tin-plated steel sheet, wherein the electrolytic treatment solution does not contain F ion and where an amount of a nitrate ion contained is 11,500 to 25,000 ppm by weight. |
