Abstract
The invention belongs to the field of metal rust removing and particularly relates to a rust remover. The rust remover is composed of, by weight, 10-21 parts of polyglutamic acid, 20-31 parts of complexing agents, 7-21 parts of sodium carbonate, 5-8 parts of purified water, 7-17 parts of sodium chloride and 3-15 parts of acetum. The rust remover has the advantages that when the rust remover is used, no obvious smog and harmful gases are produced; the rust remover does not irritate the skin, and no allergic phenomenon occurs to human bodies. In the rust removing process, almost no waste liquid is produced, so that the environment is not polluted, and convenience is brought to the environmental conservation work.
Description
Technical field
The invention belongs to metal-derusting field, be specially a kind of rust remover.
Background technology
Metal gets rusty easily under being placed in outdoor or open-air condition, 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, causing unnecessary financial loss.The rust cleaning mode one that metal is conventional is physics rust cleaning, namely adopts the mode such as frosted, sandblasting to remove the rust of metallic surface, but this mode eliminates rust and is only applicable to simple workpiece, and derusting quality can not be guaranteed; Another kind of mode is chemical rust removing, 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, is conducive to their reduction with high price iron of peeling off, accelerates the process of pickling.As Chinese patent CN104087965A " a kind of rust remover ", be made up of the feed composition of following number: 30-35 part phosphoric acid, 18-22 part formic acid, 10-12 part ethanol, 15-18 part hydrochloric acid, 5-6 part boric acid, 7-8 part polyoxyethylene glycol, 3-5 part sodium laurylsulfonate, 5-8 part cocoanut fatty acid diethanolamide, 6-8 part sodium stearate, 5-7 part polyvinyl alcohol, 4-5 part stearin, 2-3 part water glass, 3-4 part methyl alcohol, 6-7 part acetic acid, the pure pure water of 50-55 part.And for example Chinese patent Chinese patent CN103774158A " a kind of rust remover ", by hydrochloric acid 36.2%-74.5%, dilute sulphuric acid 9%-35%, Sodium dodecylbenzene sulfonate 2%-11%, dioxygen pure water 1%-7.5%, trolamine 1%-5%, citric acid 0.3%-2%, sodium-chlor 0.6%-3%, acetone 5%-35% form, and described per-cent is mass percent.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, causes the mechanical properties decrease of metal, affects 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.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of rust remover, realizing not producing smog and obnoxious flavour in descaling process by improving formula, and the disposable comprehensive rust cleaning of energy, improve rust cleaning efficiency.
Concrete technical scheme of the present invention is, a kind of rust remover, comprises the material of following weight fraction:
Polyglutamic acid 10-21 part
Complexing agent 20-31 part
Sodium carbonate 7-21 part
Pure water 5-8 part
Sodium-chlor 7-17 part
Vinegar 3-15 part.
As preferred technical scheme of the present invention, a kind of rust remover also comprises the substance of 10-30 part, and described substance is the multiple of a kind of or any weight ratio in coffic acid, sinapinic acid, TRANSCINNAMIC ACID or Citrate trianion.
As preferred technical scheme of the present invention, described Citrate trianion is preferably Trisodium Citrate.
As preferred technical scheme of the present invention, described complexing agent is any weight ratio mixture of EDTA, amino two methene phosphoric acid salt, carboxylic ethylene dinitrilotetra-acetic acid or three.
As preferred technical scheme of the present invention, described amino two methene phosphoric acid salt preferably amino two methene sodium phosphates.
Beneficial effect of the present invention is
The present invention makes full use of the adsorption function of polyglutamic acid and slightly acidic removes rusty scale, and adopts complexing agent to adsorb metal ion in the rusty scale be reduced; Adopt vinegar, sodium-chlor and sodium carbonate, can assist and promote rust cleaning in the pure water solution of polyglutamic acid, rust cleaning completely.
What rust remover of the present invention adopted is polyglutamic acid and other substance; obviously do not produce smog and obnoxious flavour in use; not skin irritation; the advantages such as allergic phenomena can not be there is to human body; substantially the generation of waste liquid is not had in descaling process; do not pollute the environment, bring very large benefit to environmental protection work.
