Description
Technical field
The invention belongs to industrial circle, specifically a kind of gentle rust remover.
Background technology
Acid can occur chemical reaction with rust and metal-oxide, generates solubility salt, thus reaching the purpose of rust cleaning,
While rust cleaning, acid again can and underlying metal react releasing hydrogen, Hydrogen Energy produces pressure to the oxide skin of rust and indissoluble, has
Beneficial to the reduction of their peeling and high price ferrum, accelerate the process of pickling, but traditional acid solution processing method there is also substantially
Defect: i.e. in processing procedure the generation of a large amount of hydrogen can make steel produce Hydrogen Brittleness Phenomena, cause the mechanical properties decrease of metal,
The intensity of impact iron and steel itself；Easily form acid mist, the equipment around the health of impact operator and corrosion and environment simultaneously；Acid
The consumption of liquid is also larger, increases processing cost；This kind of acid can form excessive erosion to steel.In addition a large amount of residues producing, need
Often discharge, both heavy corrosion industrial pipelines, and contaminated soil and environment.If number of patent application is cn200710150668.4,
The applying date is 2007-12-03, the invention of entitled " removing the new method of the rust on steel device with concentrated hydrochloric acid or concentrated sulphuric acid "
Patent, its technical scheme is: the present invention relates to a kind of use concentrated hydrochloric acid or concentrated sulphuric acid remove the new method of the rust on steel device.
Add carbamide in hydrochloric acid or sulphuric acid, or add ammonium sulfate in sulphuric acid, for removing the rust on iron and steel.The simply hydrochloric acid consuming
Or sulphuric acid, carbamide or ammonium sulfate do not consume, but play and prevent acid mist from occurring, and reduce acid and the inhibitor of ferrum corrosion itself is acted on.
When acid is depleted to similar, supplement concentrated hydrochloric acid or concentrated sulphuric acid one after another, rust cleaning is with regard to constantly carrying out.But above-mentioned patent exists
During life-time service, iron and steel can be damaged in itself and be removed although becoming rusty, but iron and steel also receives damage, lose more than gain.
