Description
Technical field
The present invention relates to a kind of preparation methods of room temperature low-corrosiveness carbon steel rust remover, belong to metal-derusting technical field.
Background technology
Straight carbon steel is widely used general, bicycle rack, front fork, mud guard, clothing branch in bicycle, electric bicycle industry
The parts such as frame are using common carbon steel material, and this kind of metal parts later stage is required for making external coating or plating processing, usually
It needs to make component surface the processing such as oil removing, derusting, scale removal, to increase deep layer binding force and antirust ability, so part
Surface cleaning problem is always one of domestic bicycle trade focus of attention problem.
And most common straight carbon steel rust remover is inorganic acid at present, and straight carbon steel is washed with strong acid under the high temperature conditions
It washs, the defects of this method is that required energy consumption is big, and strong acid is big to steel substrate corrosivity, acid mist is more, and is derusted, except oxidation
The speed of skin is slower.
Therefore, invention is a kind of can just work at normal temperatures, and, derusting fireballing environmental protection small to steel substrate corrosivity
Type carbon steel rust remover has positive meaning to metal-derusting technical field.
Invention content
Present invention mainly solves the technical issues of, be inorganic acid for common carbon steel rust remover at present, in high temperature item
Straight carbon steel is washed with strong acid under part, the defects of this method is that required energy consumption is big, and strong acid corrodes steel substrate
Property it is big, acid mist is more, and derusts, the slow defect that descales, provide a kind of room temperature low-corrosiveness carbon steel rust remover
Preparation method.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is:
A kind of preparation method of room temperature low-corrosiveness carbon steel rust remover, it is characterised in that specifically preparation process is:
(1)Red bayberry and new fresh grape are weighed, is put into tissue pulverizer after being rinsed 1~2 time with deionized water, crushing 20~
30min obtains mixed powder and minces, then mixed powder is minced and obtains fermentation substrate with after glucose mixing;
(2)Fermentation substrate is fitted into fermentation tank, control charge weight is the 4/5 of fermenter volume, after loading, uses cork
Fermentation tank mouth is clogged, is sealed by fermentation 25~30 days, after fermentation, is separated by filtration to obtain filtrate, it is spare;
(3)By mass ratioes is waited to weigh tealeaves and tea seed, tealeaves and tea seed are put into mortar, 20~30min is ground and obtains
Crushed material is fitted into after mixing crushed material, water and cellulase and pectase in enzymatic vessel, and heat preservation 8~10h of enzymolysis is obtained
Enzymolysis product;
(4)It is fitted into the three-necked flask with blender, uses after above-mentioned enzymolysis product and wool and spare filtrate are mixed
Stopper clogs the bottleneck of three-necked flask, then three-necked flask is moved into oil bath pan, heat temperature raising, starts blender stirring extraction;
(5)After treating said extracted, by three-necked flask extract move into centrifuge in, centrifugal treating, it is isolated on
Layer liquid, by the mixed in hydrochloric acid that upper liquid and mass fraction are 30%, up to room temperature low-corrosiveness carbon steel rust remover after tinning.
Step(1)Described in red bayberry and new fresh grape mass ratio be 1:2, the mass ratio that mixed powder minces with glucose
It is 5:1.
Step(2)Described in sealing and fermenting temperature be 22~25 DEG C.
Step(3)Described in crushed material, water and cellulase and pectase mass ratio be 10:20:1:1, heat preservation
The temperature of enzymolysis is 30~35 DEG C.
Step(4)Described in enzymolysis product and wool and the mass ratio of spare filtrate be 1:1:10, heat temperature raising
Temperature for 100~120 DEG C, the rotating speed for stirring extraction is 100~200r/min, and the time for stirring extraction is 20~30min.
Step(5)Described in centrifugal treating rotating speed for 2000~3000r/min, time of centrifugal treating for 15~
The hydrochloric acid volume mass ratio that 20min, upper liquid and mass fraction are 30% is 3:1.
The beneficial effects of the invention are as follows:
(1)The two is blended first using the red bayberry for being rich in organic acid and flavone compound and grape as raw material by the present invention
Fermentation, obtains self-control fruit wine, then chooses the tealeaves rich in tea polyphenols and the tea seed rich in Tea Saponin grinds and digests, will
Enzymolysis product is blended with rich lanolated wool, then tea polyphenols and tea in enzymolysis product are extracted with the self-control fruit wine after heating
Lanolin in saponin and wool finally obtains and contains organic acid and flavone compound, tea polyphenols, lanolin, tea simultaneously
Extracting solution and hydrochloric acid blending finally can be prepared by room temperature low-corrosiveness carbon steel rust remover, this hair by saponin and the extracting solution of alcohols
Bright obtained room temperature low-corrosiveness carbon steel rust remover can derust work at normal temperatures, and required low energy consumption;
(2)Contain natural surfactant Tea Saponin and lanolin in room temperature low-corrosiveness carbon steel rust remover produced by the present invention,
Wherein lanolin has good cohesive force to metal surface, and the two natural surfactant can promote cleaning agent and Metal Substrate
The wetting in body surface face by soaking, emulsifying, destroying or weakening the adhesive force of metal surface greasy dirt, ensures derusting organic acid and salt
Sour component can be in direct contact with metal, so as to improve the efficiency of derusting, in addition contain organic acid in fruit wine, its energy and straight carbon steel
The iron ion on surface generates coordination, accelerates the dissolving of iron rust oxide skin, has shortened the derusting time, realized to the disposable of straight carbon steel
Oil removing, the effect for derusting, descaling;
(3)During the use of room temperature low-corrosiveness carbon steel rust remover of the present invention, on the one hand produced by during wine fermentation
Raw free property carboxyl and the oxide of straight carbon steel matrix surface chemically react, and straight carbon steel gold is removed in the form of metallic soap
The oxidation film of metal surface, another aspect organic acid and metal oxide form metal salts of organic acids, and by the moisture in rust remover
Dissolving removal, and the remaining acid ingredient for remaining in straight carbon steel surface then can completely be waved under the action of the alcohols material in fruit wine
Hair or activity are greatly lowered, and are kept inertia under atmospheric environment, are reduced the corrosivity to straight carbon steel surface, and are dissolved in fruit wine
Tea polyphenols and flavone compound have splendid inoxidizability, can be sent out to avoid the straight carbon steel matrix after being derusted by organic acid
Raw secondary oxidation, has broad application prospects.
