Description
Technical field
The present invention relates to anti-corrosion of metal field, more particularly to a kind of natural environmental-protective metal-derusting for automation equipment
Agent.
Background technology
The material that automated production equipment and its part are commonly used is generally steel, and corrosion easily occurs during use.Pass
The chemical derusting of system can chemically react usually using strong acid, acid with iron rust and metal oxide, generate solubility salt, from
And reaching the purpose of derusting, while derusting, sour and can and underlying metal react and release hydrogen, and Hydrogen Energy is to iron rust and indissoluble
Oxide skin produces pressure, be advantageous to they peeling and high price iron reduction, accelerate the process of pickling, but traditional acid solution is handled
Method there is also it is obvious the defects of：The generation of a large amount of hydrogen can make steel produce Hydrogen Brittleness Phenomena i.e. in processing procedure, cause gold
The mechanical properties decrease of category, influence the intensity of steel in itself；Acid mist is easily formed simultaneously, influences health and the corrosion week of operating personnel
The equipment and environment enclosed；The consumption of acid solution is also larger, increases processing cost；This kind of acid can form excessive erosion to steel.In addition,
It is substantial amounts of to produce residue, need to often it discharge, both heavy corrosion industrial pipeline, and contaminated soil and environment.
The Chinese patent of Application No. 201310646506.5 discloses a kind of neutral without phosphorus rust remover, and normal temperature uses, right
Environmental nonpollution, and anti-rust problem can be improved.But this rust remover is mainly using the complexing derusting of a large amount of complexing agents, cost
It is higher, higher is required to pH value.
The Chinese patent of Application No. 201611218731.9 discloses a kind of natural rust remover, contains sword in the rust remover
Auricle grass extract, it is safe and non-toxic, there is good rust removing function to metal, but this rust remover be paste or solid-state, it is necessary to
Rusty part use is applied to, it is troublesome in poeration, it is not suitable for automated production.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides a kind of natural environmental-protective metal-derusting for automation equipment
Agent, avoid, using disagreeableness raw materials of environment such as inorganic acid and phosphorus, to spray or soaking use, it is easy to operate, to operator
Member and surrounding apparatus are harmless, in the derusting anti-corrosive technique for the food automated production equipment that is particularly suitable for use in.
The present invention concrete technical scheme be：The rust remover contains following components：45-65wt% organic acids, 2-10wt% ovum
Phosphatide, 1-5wt% aminosals, surplus are water.
Organic acid is used as main derusting composition, to environment nontoxic pollution-free.But because organic acid acidity is compared and salt
Acid or sulfuric acid are weaker, therefore add lecithin as accelerator, and lecithin is a kind of natural surfactant, can be helped organic
Acid infiltration, wetting metal surface, promote the progress of descaling process；In addition, lecithin can also be used as dispersant simultaneously, prevent organic
Mutually assemble between acid, increase active area；Aminosal has the function that inhibition, also containing organic in being especially formulated
Acid, protein can be promoted to hydrolyze, therefore requirement of the formula of the present invention to raw material is relatively low, can reduce cost.
Preferably, the rust remover contains following components：55-62wt% organic acids, 5-8wt% lecithin, 2-4wt% hydrolysis
Protein, surplus are water.
Preferably, the organic acid is citric acid or lactic acid.
Preferably, the aminosal is the hydrolysate of human body or animal hair.
Preferably, the preparation method of the aminosal is：After hair is carried out into broken pretreatment, pawpaw egg is added
White enzyme and water, and pH value is adjusted to 6-8, filtered after digesting 2.5-4h through anion exchange resin, obtain aminosal.
Preferably, the aminosal is the waste liquid after human body or animal hair hydrolysis extraction cystine.
The amino acids industry in China flourished in recent years, particularly hair-hydrolyzation method production CYSTINE, however, according to survey
Examination, extract in a large amount of mother liquors after cystine, also containing 10 kinds of amino acid are had more than, directly discharge and waste resource, but due to
It also cannot be used directly for manufacturing food or medicine containing poisonous and harmful substances such as a small amount of heavy metals in hair, and be used as rust remover
Raw material, without increasing the post-processing steps such as removal of impurities, purification, both reduce cost, and environment-friendly, solve hair-hydrolyzation
Waste water.
It is compared with the prior art, the beneficial effects of the invention are as follows：Inventive formulation all using it is nontoxic, pollution-free, can drop
The natural material of solution, environment-friendly, cost is relatively low, and technique is simple, removes rusty stain positive effect, and through the rust remover of the present invention
After processing, there is certain counnter attack rust effect, therefore without washing, the next step can be directly entered, remained on a small quantity even if having
It is harmless to operating personnel and surrounding devices, in the derusting anti-corrosive technique for the food automated production equipment that is particularly suitable for use in.
