Anti-freezing solution for bulk particle cargo transportation and preparation process thereof

Abstract

The invention relates to the technical field of anti-freezing solution production, and particularly discloses an anti-freezing solution for bulk particle cargo transportation and a preparation process. The anti-freezing solution comprises an anti-freezing agent A, an anti-freezing agent, water and anhydrous calcium chloride, the anti-freezing agent A is prepared from 1000 to 1300 parts of water, 250 to 350 parts of lignosulfonate, 150 to 180 parts of ethylene glycol, 20 to 22 parts of imidazoline, 8 to 10 parts of a Tween 80 emulsifier and 4 to 6 parts of a de-foaming agent; the anti-freezing agent B is prepared from 600 to 700 parts of water, 150 to 170 parts of sugar sodium, 155 to 165 parts of sodium nitrite, 35 to 50 parts of triazole, 8 to 12 parts of urotropine, 6 to 10 parts of HEDP tetrasodium and 4 to 8 parts of caustic soda; the anti-freezing solution disclosed by the invention can prevent a heavy vehicle from being unfrozen in an unfreezing chamber, saves energy, can solve the phenomenon that the leakage time of the wagon in a factory is too long due to insufficient capacity of the unfreezing chamber, and accelerates the turnover speed of the wagon; the product has a dustproof function, and freezing prevention, unfreezing and dust prevention are carried out synchronously; and meanwhile, the secondary unfreezing phenomenon caused by the fact that the wagon still carries materials after unloading due to insufficient unfreezing can be avoided.

Description

technical field [0001] The invention relates to the technical field of antifreeze production, and specifically discloses an antifreeze for transporting bulk granular goods and a preparation process thereof. Background technique [0002] The transportation of bulk goods such as coal and ore powder is an important part of railway freight transportation. In northern my country, the winter is relatively cold, and water-containing bulk goods such as washed coal and mineral powder are prone to freezing during winter transportation, resulting in frozen cars, which makes it difficult to unload cars at unloading stations and seriously affects the normal turnover of railway vehicles. [0003] In the face of the above-mentioned problems in the transportation of bulk granular goods, it is necessary to use antifreeze. The antifreeze is economical, convenient and effective in unloading bulk granular goods, reducing vehicle residence time, and improving transportation efficiency. It is ver...
