| titleOfInvention | A kind of chromium-free passivation liquid and its application method for tin plate |
| abstract | The present invention relates to a kind of chromium-free passivation liquid and its application method for tin plate, which does not contain chromium, solves the high technical problem of the chromium-free passivation liquid manufacturing cost and use cost of existing tin plate.A kind of chromium-free passivation liquid for tin plate, the pH value of the chromium-free passivation liquid is 1.0~2.0, and its component and proportion are as follows: zinc dihydrogen phosphate, and its content is 5~20g/L；Sodium nitrate, and its content is 1~5g/L；OP-10, and its content is 0.2~2g/L；Fluotitanic acid ammonia, and its content is 1~10g/L；The pH value of chromium-free passivation liquid to be adjusted to 1.0~2.0 phosphoric acid, surplus is water.Chromium-free passivation liquid of the present invention treated cold rolling tin plate has excellent corrosion resistance, sulfuration resistant performance, Paint Adhesion energy；Chromium-free passivation liquid of the present invention directlys adopt spraying, compares electrolytic passivation technique, economize on electricity is significant, and does not generate waste liquid, environmentally friendly. |
