Description
Technical Field
The invention belongs to the technical field of metal surface treatment, and particularly relates to a one-step treatment method for steel rust removal, rust prevention and blackening.
Background
At present, the conventional steel rust removal, rust prevention and blackening methods generally comprise pickling rust removal, sand blasting rust prevention, water washing, phosphating blackening or oxidation blackening, and finally soaking in rust-proof oil, a film protecting liquid, an antirust paint and the like to enhance the protection performance, the process is complex, the waste time and labor are consumed, three wastes are generated in the treatment process, and the harm is generated to the environment and the health of operators.
Aiming at the problems, a reagent which directly converts rust into rust removal and delamination without removing rust appears in the market. However, the medicament on the market generally has incomplete conversion to a thicker rust layer, loose protective layer and white 'ash hanging' phenomenon. Therefore, by optimizing the formula, the one-step steel rust-removing, rust-preventing and blackening treating agent and the treating method are invented, the rust layer is completely converted, the formed conversion film is uniform and compact, and the color is black, and the phenomenon of ash hanging does not occur in the using process.
Disclosure of Invention
