Deicing fluid for railway carriage and preparation method thereof

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...
