Description
Technical field
The invention belongs to industrial circle, specifically a kind of novel rust remover.
Background technology
Traditional chemical rust removing uses strong acid usually, acid can with iron rust and metal oxide generation chemical reaction, generate solubility salt, thus reach the object of rust cleaning, while rust cleaning, acid to react releasing hydrogen with underlying metal again, the oxide skin of Hydrogen Energy to iron rust and indissoluble produces pressure, be conducive to their reduction with high price iron of peeling off, accelerate the process of pickling, but traditional acid solution treatment process also also exists obvious defect: namely in treating processes, the generation of a large amount of hydrogen can make steel produce Hydrogen Brittleness Phenomena, cause the mechanical properties decrease of metal, affect the intensity of iron and steel itself, easily form acid mist simultaneously, affect the health of operator and corrode equipment around and environment, the consumption of acid solution is also comparatively large, increases processing cost, this kind of acid can form excessive erosion to steel.In addition a large amount of residue produced, need often discharge, both heavy corrosion industrial pipeline, again contaminated soil and environment.If number of patent application is CN200710150668.4, the applying date is 2007-12-03, the patent of invention that name is called " novel method with the iron rust on concentrated hydrochloric acid or vitriol oil removing steel device ", its technical scheme is: the novel method that the present invention relates to the iron rust on a kind of concentrated hydrochloric acid or vitriol oil removing steel device.In hydrochloric acid or sulfuric acid, add urea, or add ammonium sulfate in sulfuric acid, be used for removing the rust on iron and steel.Just hydrochloric acid or the sulfuric acid that consume, urea or ammonium sulfate do not consume, but play and prevent acid mist from occurring, reduce the inhibitor effect that acid is corroded iron itself.When acid is depleted to similar, supplement concentrated hydrochloric acid or the vitriol oil one after another, rust cleaning is just constantly carried out.But above-mentioned patent is when life-time service, can damage iron and steel itself, although rust has been removed, iron and steel has also received damage, loses more than gain.
Summary of the invention
In order to overcome the problem of the meeting injury iron and steel that existing novel rust remover exists itself, now a kind of novel rust remover that can not injure iron and steel is proposed.。
