Original Title: Good Helper for Railway Coal Transportation in Northern China in Winter-Anti-freezing Dust Suppressant Antifreezing dust suppressant is an antifreezing dust suppressant specially developed for railway coal transportation in northern China in winter. The dust suppressant well combines the dust suppression function and the anti-freezing function together, so that the dust suppressant not only has excellent moisture retention, bonding, film forming and crusting capabilities, but also has an effective anti-freezing function, thereby well solving the problems encountered in coal transportation by trains in northern areas in cold winter. The outstanding features of the antifreeze dust suppressant include: 1, that antifreeze dust suppressant organically combines dust suppression and antifreeze, so that the product has various effects of antifreezing,decarboxylation after extraction, moisturizing, bon, forming a film, forming a shell and the like. And 2,rotary vacuum evaporator, the antifreezing dust suppressant is an instant type, is easy to dissolve in water, does not agglomerate or pill in water, reduces the stirring time, saves electric energy, reduces the labor intensity of workers, winterization filtration ,jacketed glass reactor, and is more convenient to use. 3. The dust suppression component of the antifreezing dust suppressant is modified plant fiber, which can form a high-viscosity network structure when sprayed on the surface of coal, and has good dust suppression effect. 4. The antifreezing dust suppressant can greatly reduce the freezing point and prevent the bulk water-containing materials and wagons from freezing. In severe cold seasons or severe cold areas, the bulk materials containing water transported by wagons, such as mined coal, will be frozen together with the wagons and cannot be unloaded. Before unloading, they must be thawed in the thawing room, which not only wastes a lot of time, but also consumes a lot of resources, reduces the efficiency of vehicles, increases transportation costs, and delays production. And 5, that dust suppressant is a powdery product, is more convenient and SAF to store and transport than a liquid dust suppressant, and is not affected by cold weather. Usage: 1. Preparation of the antifreezing dust suppressant solution: according to the local winter temperature, add the antifreezing dust suppressant into the water according to the proportion recommended by the sales engineer, and stir it while adding materials until it is completely dissolved, that is, prepare the dust suppresser solution. 2. Spraying amount of dust suppressant liquid: coal shall be sprayed on the surface of coal at the amount of 1.6 to 2 liters per square meter during railway transportation. If the coal has a high moisture content, the spray rate may be increased to 2.5 to 3.5 liters per square meter for frost protection.
