| titleOfInvention | High-efficiency one-step acid-washing stainless steel passivation cream |
| abstract | The invention discloses a kind of single stage method acid-washing stainless steel passivation cream, be made up of each component of following mass percentage, tripoly phosphate sodium STPP 1.5-2.0%; Magnesium Stearate 1.5-2.0%; Magnesium nitrate 35-38%; Hydrofluoric acid 9-10%; Nitric acid 12-13%; Thickening material surplus.Also inhibiter can be added in formula.Acid-washing stainless steel passivation cream of the present invention, pickling and passivation one step complete, and pickling speed is fast, and pickling, passivation effect are up to state standards.Owing to strictly limiting the content of the harmful element used in this formula, the harmful effect of butt welded seam is little, thus makes the effect that the use of acid wash passivation cream reaches safe.Add inhibiter in formula, can effectively suppress weld seam to be corroded.Present invention also overcomes the problem that the acid wash passivation color of currently available products existence is inconsistent, steady quality, at Various Seasonal acid wash passivation effect indifference. |
