| titleOfInvention | Chromium-free passivator with high corrosion resistance for batch hot galvanizing |
| abstract | The invention belongs to the technical field of metal surface treatment and corrosion protection, and particularly discloses a chromium-free passivator with high corrosion resistance for batch hot galvanizing. The chromium-free passivator is an aqueous solution consisting of the following components in percentage by weight: 20-200 g/L of organic phosphoric acid, 5-40 g/L of ammonium molybdate, 10-50 g/L of triethanolamine borate, 1-10 g/L of cerium nitrate, 100-500 g/L of composite silane hydrolysate and 50-200 g/L of acidic aluminum modified silica sol. The chromium-free passivator disclosed by the invention has excellent corrosion resistance and weather resistance. |
