| titleOfInvention | Composition and process for cleaning tinplate stock |
| abstract | Tinplate stock is cleaned with a cleaning bath that has a pH of 8 to 11 and that consists of water; 0.5 to 10.0 g/L of alkali builder comprising one or more selections from the alkali metal hydroxides, alkali metal and ammonium salts of inorganic phosphoric acid, alkali metal borates, alkali metal silicates, and alkali metal and ammonium carbonates; 0.05 to 1.0 g/L of chelating agent comprising one or more selections from the hydroxyalkyldiphosphonic acids, aminotrialkylphosphonic acids, ethylenediaminetetraacetic acid, nitrilotriacetic acid, condensed phosphoric acids, and the alkali metal and ammonium salts of the preceding; and 0.05 to 2.0 g/L of surfactant. The use of this bath composition allows continuous cleaning in which the production of Sn sludge is inhibited and the amount of sludge produced by wastewater treatment is reduced substantially. |
