Description
Technical field
The invention belongs to non-ferrous metal surface inorganic agent technical field, be specifically related to a kind of non-ferrous metal surface inorganic agent and preparation method thereof.
Background technology
Often there are oxidation in various degree, corrosion etc. in metal in processing, process and use procedure; reduce the service life of metal material or hardware, accordingly, it would be desirable to metal surface is processed; increase its antioxidation, erosion-resisting ability, increase the service life. Application is the technology that Treatment of Metal Surface is conventional, and in coating process, phosphatization can produce substantial amounts of phosphorus-containing wastewater, and needs to carry out under strong acid or strong alkaline condition, and the healthy of people and environment are caused great harm. Traditional chemical derusting generally uses strong acid, acid can with rust and metal-oxide generation chemical reaction, generate solubility salt, thus reaching the purpose of rust cleaning, while rust cleaning, acid can react releasing hydrogen with underlying metal again, and the oxide skin of rust and indissoluble is produced pressure by Hydrogen Energy, be conducive to their peeling and the reduction of high price ferrum, accelerate the process of pickling. Acid solution processing method there is also significantly defect: namely in processing procedure, the generation of a large amount of hydrogen can make steel produce Hydrogen Brittleness Phenomena, causes the mechanical properties decrease of metal, affects the intensity of iron and steel itself; It is easily formed acid mist simultaneously, affects the health of operator and corrode equipment around and environment; The consumption of acid solution is also relatively big, increases processing cost; Steel can be formed excessive erosion by this kind of acid. In addition a large amount of residues produced, need to often discharge, both heavy corrosion industrial pipeline, again contaminated soil and environment.
