Description
Technical field
The present invention relates to a kind of steel part safety and environmental protection antirust derusting methods, belong to steel part antirust derusting technical field.
Background technique
There are about the steel part of 10-20% every year in the world causes to use due to burn into corrosion etc., steel
The antirust derusting of product is a highly important thing.With advances in technology with the development of science and technology, steel part rust preventing got over
Come more, construction technology is also not quite similar.
Existing antirust means have very much, such as can be in steel part surface application chemicals, fast filming, i.e., usually
It is so-called to use rust inhibiting solution.Steel part is surface-treated using rust inhibiting solution, reaches antirust purpose, rust-proof mechanism substantially phase
Together, all it is to form protective film on steel part surface, makes steel part matrix and air insulated, destroys corrosion condition.But it is this anti-
Rotten mode mostly uses chemical substance anti-corrosion, it is dangerous for the steel part of food-grade not environmentally.
The type of antirust agent used in Rustproof process is varied, and wherein the good antirust property and price of nitrite are low
It is honest and clean, but there is stronger carcinogenicity.There are also some other antirust agent, also there is very big pollution and destruction to environment.These are anti-
Rust method is for requiring the steel part of safety and environmental protection and being not suitable for, such as the steel part of food-grade, including tableware, kitchen tools etc..
CN101289745A discloses a kind of cast iron pan smearing rust-proofing method, mainly coats pot body using edible wax, then
With polishing buff polishing.Though the material health of edible wax itself is nontoxic, when using heating for the first time, edible wax is heated to be divided automatically
Solution, it is safe and healthy to be protected, but in later long-term use or can get rusty easily.
To sum up, the rust-proofing method for finding a kind of safety and environmental protection is a significantly thing.
Summary of the invention
The present invention is in view of the deficienciess of the prior art, provide a kind of steel part safety and environmental protection antirust derusting method, with solution
The certainly existing unsafe problem of rust-proofing method.
The technical scheme to solve the above technical problems is that a kind of steel part safety and environmental protection antirust derusting method, including
Following steps:
(1) surface of steel part is applied and spreads calcium hydroxide powder end, be placed at 140-160 DEG C and sufficiently dry, it can be in steel part
Surface formed one layer of carbonic acid ca protective film, constitute the first layer protective film of steel part so that the oxygen in steel part and air and
Moisture isolation；
(2) steel part after drying is cleaned into re-dry, is then placed in the hot solution of vinegar and tealeaves and sufficiently reacts, it can be in steel
Product surface forms antirust protective film.Ingredient collective effect in acetic acid and tealeaves, so that steel part surface forms the second layer and protects
Cuticula, second layer protective film are formed on the basis of the first layer protective film that calcium carbonate is constituted, can further be isolated steel part and
Oxygen and moisture in air, realize the antirust of steel part.
The present invention is further arranged to, and in step (1), drying time 30-90min can form suitable thickness and property
The carbonic acid ca protective film of energy.
The present invention is further arranged to, and in step (2), the mass percentage of acetic acid is in the hot solution of vinegar and tealeaves
2%-7%。
The present invention is further arranged to, and in step (2), the mass percentage of tealeaves is in the hot solution of vinegar and tealeaves
5%-10%。
The present invention is further arranged to, and the tealeaves is green tea, white tea or green tea, and green tea and white tea are non-fermented tea, green
Tea is semi-fermented tea, and green tea, the effect meeting of white tea are more preferable.
The present invention is further arranged to, and the temperature of the hot solution of the vinegar and tealeaves is 70-130 DEG C.
The present invention is further arranged to, and the pressure of the hot solution of the vinegar and tealeaves is 0.3-0.7MPa, the selection of pressure
It is to reduce rust inhibiting solution adhesiveness, antirust is molten because steel part surface is likely to occur " film boiling " phenomenon at relatively high temperatures
The pressure of liquid is not less than 0.3 MPa, can greatly improve adhesiveness.
The present invention is further arranged to, and further includes pretreatment descaling step, by untreated steel before step (1)
Product, which is placed into rust remover, to be heated, and steel part is then taken out drying；Rust remover includes that corn alcohol is molten according to mass parts
30-40 parts of albumen, 1-1.6 parts of arabo-ascorbic acid, 0.3-1.2 parts of glycerol, 1-2 parts of citric acid, 10-20 parts of 80% ethanol solution.If
Setting pretreatment descaling step is in order to which the steel part to have got rusty on surface is derusted in advance, to carry out subsequent antirust
Processing.It can be without the step if steel part surface is not got rusty.
The present invention is further arranged to, and the configuration process of the rust remover is: it is molten that zeins is first dissolved in ethyl alcohol
It is uniformly mixed in liquid, adds other compositions and be uniformly mixed.
The present invention is further arranged to, and untreated steel part is placed into rust remover and heats 2-3min.
The present invention is further arranged to, and the steel part after drying is cleaned re-dry, is then placed in the thermosol of vinegar and tealeaves
2-3min is sufficiently reacted in liquid, can form that thickness is appropriate, uniform and stable second layer protective film.
Using method of the invention to steel part carry out derusting rust-proofing processing, to the composition of rust inhibiting solution, temperature, pressure and
Time all requires, because such setting can obtain better protective film, rust-proof effect is preferable.Antirust solution can make repeatedly
With therefore, the present invention is of great significance for the antirust on steel part surface.In conclusion the present invention has below beneficial to effect
Fruit:
(1) substance used in the present invention is nontoxic, does not damage to human body；
(2) treated that steel part antirust ability is good by the present invention, is not easily corroded and rusted, extends the service life of steel part, to the greatest extent
Amount keeps its service performance；
(3) increase pretreatment descaling step, the rust on steel part can be eliminated well, to carry out antirust treatment；
(4) method of the invention is simple to operation, is suitble to large-scale popularization and application, compared to existing rust remover and antirust
Agent, and it is at low cost.
