| titleOfInvention | Galvanized layer chromium-free passivation film treatment liquid preparation method |
| abstract | The present invention discloses a galvanized layer chromium-free passivation film treatment liquid preparation method, wherein the treatment liquid comprises 24-26 g/L of ammonium molybdate, 13-17 g/L of sodium tungstate, 50-60 ml/L of 85% phosphoric acid, 10-14 ml/L of silane, 4-6 g/L of boric acid, 6-8 g/L of cerium(iii) nitrate hexahydrate, 12-16 ml/L of hydrogen peroxide, 14-16 g/L of sodium chloride, 8-10 g/L of citric acid, 7-9 g/L of carotene, and the balance of water. The preparation method comprises: adding the measured ammonium molybdate and the measured sodium tungstate to water, continuously stirring to completely dissolve, sequentially adding 85% phosphoric acid, sodium chloride, hydrogen peroxide, citric acid, silane, boric acid, cerium(iii) nitrate hexahydrate and carotene according to the ratio in the formula, uniformly stirring to completely dissolve, completely carrying out a complexation reaction for 2-3 h, and adjusting the pH value with an acid or an alkali to achieve 3-4. |
