Description
Technical field
The invention belongs to industrial circle, a kind of novel rust remover.
Background technology
Traditional chemical derusting generally uses strong acid, acid can be with rust and metal-oxide generation chemical reaction, generate solubility salt, thus reach the purpose of rust cleaning, while rust cleaning, acid can react releasing hydrogen with underlying metal again, Hydrogen Energy produces pressure to the oxide skin of rust and indissoluble, be conducive to their peel off and the reduction of high price ferrum, accelerate the process of pickling, but traditional acid solution processing method there is also significantly 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, affect 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 the biggest, increases processing cost；This kind of acid can form excessive erosion to steel.In addition a large amount of residues produced, need to often discharge, both heavy corrosion industrial pipeline, again contaminated soil and environment.If number of patent application is CN200710150668.4, filing date 2007-12-03, the patent of invention of entitled " removing the new method of rust on steel device with concentrated hydrochloric acid or concentrated sulphuric acid ", its technical scheme is: the present invention relates to a kind of concentrated hydrochloric acid or concentrated sulphuric acid removes the new method of the rust on steel device.In hydrochloric acid or sulphuric acid, add carbamide, or in sulphuric acid, add ammonium sulfate, be used for removing the rust on iron and steel.Simply hydrochloric acid or the sulphuric acid consumed, carbamide or ammonium sulfate do not consume, but play and prevent acid mist from occurring, and reduce the acid inhibitor effect to ferrum corrosion itself.When acid is depleted to similar, supplementing concentrated hydrochloric acid or concentrated sulphuric acid one after another, rust cleaning is just constantly carried out.But above-mentioned patent is when life-time service, iron and steel itself can be damaged, although rust is removed, but iron and steel also receives damage, loses more than gain.
Summary of the invention
Meeting in order to overcome existing novel rust remover to exist injures the problem of iron and steel itself, currently proposed a kind of novel rust remover that will not injure iron and steel..
For realizing above-mentioned technique effect, technical solution of the present invention is as follows:
A kind of novel rust remover, it is characterized in that: include tartaric acid, phosphoric acid, sodium lauryl sulphate, calcium bicarbonate, hexamethylenetetramine, magnesium stearate and deionized water, described tartaric mass fraction is 5-15 part, the mass fraction of described phosphoric acid is 15-25 part, the mass fraction of described sodium lauryl sulphate is 20-40 part, the mass fraction of described calcium bicarbonate is 15-35 part, the mass fraction of described hexamethylenetetramine is 5-25 part, the mass fraction of described magnesium stearate is 4-24 part, and the mass fraction of described deionized water is 500-1200 part.
Described tartaric mass fraction is 7-12 part, the mass fraction of described phosphoric acid is 17-21 part, the mass fraction of described sodium lauryl sulphate is 30-35 part, the mass fraction of described calcium bicarbonate is 26-31 part, the mass fraction of described hexamethylenetetramine is 10-20 part, the mass fraction of described magnesium stearate is 13-20 part, and the mass fraction of described deionized water is 700-1000 part.
Described tartaric mass fraction is 11 parts, the mass fraction of described phosphoric acid is 19 parts, the mass fraction of described sodium lauryl sulphate is 33 parts, the mass fraction of described calcium bicarbonate is 28 parts, the mass fraction of described hexamethylenetetramine is 14 parts, the mass fraction of described magnesium stearate is 17 parts, and the mass fraction of described deionized water is 900 parts.
Also including thiourea and Biformyl, the mass fraction of described thiourea is 10-30 part, and the mass fraction of described Biformyl is 20-35 part.
The mass fraction of described thiourea is 19 parts, and the mass fraction of described Biformyl is 26 parts.
The concentration of described phosphoric acid, sodium lauryl sulphate, calcium bicarbonate, hexamethylenetetramine, magnesium stearate, thiourea and Biformyl is 30-50%.
It is an advantage of the current invention that:
1, iron and steel will not be caused corrosion or other injuries by the present invention, and the rust on iron and steel well can be eliminated, even if ensure that the advantage that life-time service also will not destroy iron and steel, utilize large-scale popularization and application, and each composition is with low cost, compared to existing novel rust remover, the input cost of user can be substantially reduced.
