Problems solved by technology

[0002] In severe winter or severe cold regions, wagons are used to transport water-containing bulk materials, such as ore concentrate powder and mined coal, which will be frozen together with the wagons and cannot be unloaded. Before unloading, they must be thawed in a thawing room. It not only wastes a lot of time, but also consumes a lot of energy, which reduces the efficiency of vehicles, increases transportation costs, and delays production

Embodiment 1

[0036] According to the wagon antifreeze of the present invention, it is made up of the following weight percentage components:

[0037] Anhydrous calcium chloride (industrial grade) 30%

[0038] Ethanol (95%) 10%

[0039] water 60%,

[0040] Its preparation method comprises the following steps:

[0041] 1) injecting 60% water into the stirring tank by weight percentage,

[0042] 2) be 30% calcium chloride anhydrous drop in tank by weight percentage, stir, until all dissolving,

[0043] 3) Remove the foam generated during stirring and dissolving,

[0044] 4) Continue to stir to release the heat generated when the anhydrous calcium chloride is dissolved, so that the temperature of the solution is reduced to 19°C to 21°C,

[0045] 5) Add 10% ethanol by weight, stir evenly, and make wagon antifreeze.

Embodiment 2

[0047] When the antifreeze needs to be used for materials and wagons that are prone to rust, rust inhibitors, such as sodium nitrite, can be added to the components. The weight percentage of this wagon antifreeze is:

[0048] Calcium Chloride Anhydrous 25%

[0049] Ethanol 9%

[0050] Sodium nitrite 1%

[0051] Water 65%.

[0052] Its preparation method comprises the following steps:

[0053] 1) injecting 65% water into the stirring tank by weight percentage,

[0054] 2) be 25% calcium chloride anhydrous drop in tank by weight percentage, stir, until all dissolving,

[0055] 3) Remove the foam generated during stirring and dissolving,

[0056] 4) Continue to stir to release the heat generated when the anhydrous calcium chloride is dissolved, so that the temperature of the solution is reduced to 19°C to 21°C,

[0057] 5) Add 9% ethanol by weight and stir evenly.

[0058] 6) Putting in 1% sodium nitrite by weight, stirring for 30 minutes, and then ...

Abstract

The invention provides a railway carriage antifreezing solution and its preparing method, including the following components in weight precent: anhydrous calcium chloride 20-50%, alcohol 8-10%, and water 40-70%, and it can also adds in antirusting agent sodium nitrite in 1-2%. The preparing method: firstly adding water in a stirring jar, then adding in the anhydrous calcium chloride and stirring to fully dissolving them, eliminating foam, then stirring to the temperature at 19 deg.C-21 deg.C, adding in alcohol, adding in the antirusting agen, stirring for 30 minutes and then ending. It can ensure the vehicle skins do not freeze with the hydrous bulk materials in 10 hours in the open air, and thoroughly solves the freezing problem of the iron mine powder-like hydrous bulk materials in the winter, thus need not defreeze them in defreezing rooms to smoothly discharge, saving energy sources, shortening turnover cycle of railway carriages, reducing labor strength and reducing transport cost.

Description

technical field [0001] The invention belongs to the field of antifreeze products, in particular to an antifreeze liquid for wagons and a preparation method thereof, which are suitable for antifreezing of bulk materials transported by wagons in cold seasons and alpine regions. Background technique [0002] In severe winter or severe cold regions, wagons are used to transport water-containing bulk materials, such as ore concentrate powder and mined coal, which will be frozen together with the wagons and cannot be unloaded. Before unloading, they must be thawed in a thawing room. It not only wastes a lot of time, but also consumes a lot of energy, which reduces the efficiency of vehicles, increases transportation costs, and delays production. If there is a substance added to the water-containing bulk material or sprayed on the wagon loaded with bulk material, the freezing point can be greatly lowered to prevent the bulk water-containing material and the wagon from freezing, whi...
