Abstract
The invention discloses a ferrous metal derusting liquid which comprises the following component in parts by weight: 20-30 parts of hexamethylene tetramine, 20-30 parts of diethanolamine phosphate ester, 7-10 parts of sodium dodecyl benzene sulfonate, 2-5 parts of citric acid and 0.01-0.2 part of sodium chloride. According to the ferrous metal derusting liquid provided by the invention, the main raw materials are free of strong acid, the condition that the mechanical property of metal is reduced is avoided, and the strength of iron steel per se can be kept; the environmental influence is less, and the treatments are relatively convenient.
Description
Technical field
The present invention relates to a kind of rust removing solution.
Background technology
Ferrous metal (steel) is placed under outdoor or open-air condition and gets rusty easily, and not only affects visual appearance, also can affect normally carrying out of techniques such as spraying paint, bonding, as processed not in time, more can cause scrapping of material, causes unnecessary financial loss.
Strong acid is used in traditional chemical rust removing conventionally, acid can with iron rust and metal oxide generation chemical reaction, generate solubility salt, thereby reach the object of rust cleaning, in the time of rust cleaning, acid can react and emit hydrogen with underlying metal again, and Hydrogen Energy produces pressure to the oxide skin of iron rust and indissoluble, be conducive to their peeling off and the reduction of iron at high price, accelerate the process of pickling.
But traditional acid solution treatment process also exists obvious defect: in treating processes, 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; Easily form acid mist simultaneously, affect operator's health and corrosion equipment and environment around; The consumption of acid solution is also larger, increases processing cost; This class acid can form excessive erosion to steel.In addition a large amount of residues that produce, need often discharge, both heavy corrosion industrial pipeline, again contaminated soil and environment.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, provides a kind of containing strong acid, the ferrous metal rust removing solution more friendly to environment.
Object of the present invention is carried out specific implementation by the following technical programs:
A ferrous metal rust removing solution, each component by weight, vulkacit H 20-30 part, diethanolamine phosphoric acid ester 20-30 part, Sodium dodecylbenzene sulfonate 7-10 part, citric acid 2-5 part, sodium-chlor 0.01-0.2 part.
As preferred version, above-mentioned ferrous metal rust removing solution, each component by weight, 25 parts of vulkacit Hs, 22 parts of diethanolamine phosphoric acid ester, 8.5 parts of Sodium dodecylbenzene sulfonatees, 3 parts of citric acids, 0.2 part, sodium-chlor.
Beneficial effect of the present invention:
Ferrous metal rust removing solution provided by the present invention, main raw material has been broken away from strong acid, has avoided the mechanical properties decrease of metal, can keep the intensity of iron and steel itself; Little to environmental influence, each processes convenient.
