Abstract

The invention discloses an antifreeze liquid for transporting bulk granular goods, which is composed of the following raw materials: magnesium chloride, calcium chloride, triethanolamine, sodium citrate, hydroxyethyl cellulose and water. The advantages of the present invention are: the present invention uses magnesium chloride, which is non-irritating to the skin and less corrosive to vehicles than calcium chloride, and adding an appropriate amount of calcium chloride can meet the technical standards of "Technical Conditions for Antifreeze Liquid for Bulk Granular Cargo Transport" requirements, and can significantly reduce the freezing point of antifreeze. Hydroxyethyl cellulose is first added with water and stirred, then poured into the stirred solution, and then stirred to dissolve, which solves the problem of easy agglomeration and dissolution of hydroxyethyl cellulose. Insufficient problem, its thickening, suspension, bonding, and film-forming effects are very significant, which solves the adhesion problem of spraying antifreeze on the facade of the wagon compartment of transport vehicles. The invention is widely used in the transportation of bulk granular goods.

Description

technical field [0001] The invention relates to an antifreeze liquid, in particular to an antifreeze liquid for transporting bulk granular goods and a preparation method thereof. Background technique [0002] Bulk granular goods such as washed coal and ore powder containing moisture are prone to freeze and difficult to load and unload when transported in winter in a climate below -5°C. It will cause significant economic losses, and seriously affect the efficiency and safety of railway and port operations. Antifreeze is economical, convenient, and effective in unloading bulk granular cargo, reducing vehicle dwell time, and improving transportation efficiency. Therefore, it is necessary to provide an antifreeze with a lower freezing point, good viscosity, good film-forming effect, adjustable viscosity, easy operation implementation, and meeting the antifreeze requirements of different materials during transportation. Contents of the invention [0003] The purpose of the pr...
