| titleOfInvention | A kind of steel surface passivation treatment fluid |
| abstract | The present invention discloses a kind of steel surface passivation treatment fluid, contain following component: hydrofluoric acid 1%~15%, fluosilicate 0.1%~5%, cerium salt 0.1%~5%, oxidant 0.1%~5%, sodium benzoate 0.1%~5%, Gemini surface active agent 0.001%~0.5%, hexa 0.001%~0.005%, remaining is water, it is 2 ~ 5 with the pH that hydrochloric acid adjusts the treatment fluid, wherein the oxidant is H 2 O 2 , sodium peroxide, ammonium persulfate, at least one of Peracetic acid；The Gemini surface active agent is at least one of dodecyl dimethyl ammonium chloride, dodecyldimethylamine ammonium chloride.The steel surface passivation treatment fluid film layer that steel surface is formed it is smooth it is fine and close, stability is high, the passivating film excellent anti-corrosion performance of generation is nontoxic, degradable, can reduce pollution level to environment, a kind of environmentally friendly reagent treatment. |
