Problems solved by technology

At present, most of the two types of products on the market only have a single antifreeze function or dust suppression function, and in the actual use of the original antifreeze, the temperature is low, the moisture content of the cargo is high, and the transportation process takes a long time. It is very easy to decompose and volatilize under the environment, which obviously reduces the antifreeze effect, and the car is often frozen when sprayed with a sufficient amount of antifreeze according to the standard. It is volatile and causes economic losses at the same time; the use of dust suppressant has the side effect of weakening the effect of antifreeze, and it does not meet the dust suppression regulations if it is not used; in addition, antifreeze and dust suppressant need their own matching when used Facilities, equipment and staff have high investment costs and heavy burdens on enterprises, which cannot achieve the effect of antifreeze and dust suppression in winter transportation, making winter transportation antifreeze and dust suppression the problem of mutual resistance to stains

Abstract

The invention belongs to the technical field of dust suppression and antifreezing solutions for bulk granular cargo transportation, and relates to a dust suppression and antifreezing solution for coal transportation and a preparation method thereof. The dust suppression and antifreezing solution for coal transportation has effects of efficient dust suppression and freeze protection. The dust suppression and antifreezing solution for coal transportation is prepared from 45 to 65 parts by weight of water, 10 to 38 parts by weight of anhydrous calcium chloride, 3 to 8 parts by weight of ethylene glycol, 5 to 10 parts by weight of glycerol, and 0.5 to 2 parts by weight of hydroxypropylmethyl cellose. The lowest anti-freezing temperature of the dust suppression and antifreezing solution is -55DEG C. The dust suppression and antifreezing solution for coal transportation is an improved antifreezing solution, improves a dust suppression function, viscosity, moisture retention and adhesion, reduces degrees of disintegration and volatility, improves product use performances and overcomes defects of the existing product.

Description

Technical field [0001] The invention belongs to the technical field of dust suppression and antifreeze liquid for bulk particle cargo transportation, and specifically relates to a dust suppression and antifreeze liquid for coal transportation and a preparation method thereof. Background technique [0002] During the coal transportation process, the dust caused by the air flow and the turbulence of the transportation means will cause serious pollution to the air, as well as cargo loss and economic loss; in winter, the water-containing coal and bulk particle cargoes in the northern part of my country are on the highway, During railway storage or transportation, freezing, freezing in the car and freezing of the carriage are very easy to occur, causing difficulties in loading and unloading vehicles, affecting vehicle turnover and transportation efficiency, and causing economic and profit losses to both supply and demand. [0003] According to the regulations of the Ministry of Railways,...
