Abstract
The invention provides a kind of coal transportation with highly effective to guard against corrosion the antifreeze, its component was: Glycol, calcium chloride, triethanolamine, with deionized water. The above coal transportation highly effective anticorrosion antifreeze preparation method includes: (1) solution configuration: The calcium chloride, joins in the deionized water, namely made has been ready to be used the fluid, (2) mixed the process: Joins the triethanolamine makes is ready to be used in the fluid, makes the reserve fluid, again glycol if in the reserve fluid, then continues to stir for a hour, causes the temperature drop to the room temperature, like this, has made the end product. The invention discloses testing many times in the foundation, screened pour point depressant, caused the antifreeze the solidification point greatly to reduce, had achieved -66deg.C, its anti- freezing temperatures has achieved -40deg.C, therefore had the fine low freezing point performance, also the stability was extremely good, has satisfied north the winter coal transportation request. After simultaneously in order to avoid pour point depressant oxidizing corrodes the freight car, but also has used the inhibitor technology, provides the long-term anticorrosion for the train freight car, has guarded against the rust function.
Description
Technical field
The present invention relates to a kind of frostproofer and preparation method thereof, refer in particular to, be specially Coal Transport efficient corrosion resisting frostproofer and preparation method thereof to preventing that the coal after the washing from freezing used frostproofer in transit.
Background technology
The raw coal of exploiting out is through after the washing, moisture content about having up to 20% when entrucking is deposited in the coal in the compartment, and the coal in China reserves mainly are distributed in the above high latitude severe cold area of north latitude 35 degree, therefore for many years, a large amount of coals is frozen on the compartment inwall, at this time, the method of removing freezing coal in the compartment mainly is to utilize artificial or half mechanical mode, there is inefficiency undoubtedly, time-consuming drawback, and prolonged circulation time of train railway carriage, seriously influence the transportation of coal, caused great financial loss.For addressing this is that, in the middle of actual the use, also there is the frostproofer of some similar performances to be used, but, its anti-freeze temperature only can reach-15 ℃, can not satisfy the requirement in the north, also not have at present discovery that the relevant report of the frostproofer that the Coal Transport of being exclusively used in uses is arranged.
Summary of the invention
The present invention is frozen in problem on the compartment inwall in order to solve in north of china in winter Coal Transport process a large amount of coal, a kind of Coal Transport efficient corrosion resisting frostproofer is provided, and its preparation method is provided.
Technical scheme of the present invention realizes in the following way: a kind of Coal Transport efficient corrosion resisting frostproofer, its component and proportioning (weight percent) are: ethylene glycol: 25%--40%, calcium chloride and/or magnesium chloride: 20%--35%, trolamine: 5%--8%, all the other are deionized water.
Above-mentioned Coal Transport comprises with the preparation method of efficient corrosion resisting frostproofer: the preparation of (1) solution: with the calcium chloride and/or the magnesium chloride of aforementioned proportion, at normal temperature and with under the stirring condition, add in the deionized water of aforementioned proportion, promptly made stand-by liquid; (2) mixing process: the trolamine of aforementioned proportion under stirring condition, is added in the stand-by liquid of making, make reserve liquid, ethylene glycol with aforementioned proportion adds under same condition in the reserve liquid again, continues then to stir 1 hour, makes temperature reduce to room temperature, like this, just made finished product.
In order further to improve the antiseptic property of Coal Transport of the present invention with the efficient corrosion resisting frostproofer, can be in the solution preparation, under same condition, adding accounts for the Sodium Benzoate of described Coal Transport with the 4%--5% of efficient corrosion resisting frostproofer component gross weight.Also can be in the solution preparation, under same condition, adding accounts for the borax of described Coal Transport with the 1.5%--2% of efficient corrosion resisting frostproofer component gross weight.Also can be in the solution preparation, under same condition, add simultaneously and account for described Coal Transport with the Sodium Benzoate of the 3%--5% of efficient corrosion resisting frostproofer component gross weight with account for the borax of the 3%--5% of described Coal Transport usefulness efficient corrosion resisting frostproofer component gross weight.
The present invention is on the basis of repeatedly experiment, filtered out ethylene glycol as pour point depressant, Coal Transport of the present invention is reduced greatly, according to the standard of GB510-83, after testing with the zero pour of efficient corrosion resisting frostproofer, zero pour can reach-66 ℃, its anti-freeze temperature has reached-40 ℃, thus have good low freezing point performance, owing to added trolamine again, so zero pour is stable splendid, satisfied the requirement of north of china in winter Coal Transport.The acidic substance corrosion railway carriage that generates for fear of the oxidized back of pour point depressant has also adopted organic salt inhibitor technology, for the train railway carriage provides secular anticorrosion, corrosion protection simultaneously.
