Railway coal transportation dust-depressor and manufacturing method thereof

Abstract

The invention discloses a coal railway transportation dust depressor, which is invented for solving the problems of high cost, poor depression effect and so on in the prior art. The raw materials by weight percent for preparing effective compositions in the coal railway transportation dust depressor are: 2 to 7 percent of synthesized water-soluble polymer, 0.1 to 5 percent of modified cellulose water-soluble polymer, 85 to 95 percent of water and 0 to 2 percent of bluestone, wherein the synthesized water-soluble polymer is prepared by complexing at least two water-soluble polymers. The coal railway transportation dust depressor consists of more than two synthesized water-soluble polymers and a small amount of auxiliary agent, and has the advantages of high viscosity and low cost. When used, the coal railway transportation dust depressor is uniformly sprayed on particles on the surface of a coal bed to form a curing layer with certain strength, thereby the coal-dust particles of various grain sizes are bonded together and have certain toughness, and the aim of preventing flying dust on the surface of the coal bed is achieved.

Description

Technical field: [0001] The invention relates to a dust suppressant for railway coal transportation and a manufacturing method thereof. Background technique: [0002] With the deepening of the railway leap-forward development process, the train speed has been greatly improved, and the transportation of railway bulk coal accounts for 40% of the entire railway freight volume. Due to the current way of transporting coal or other powders in the train carriages, generally no measures are taken to isolate the flying powder, the coal trains are bumped and the wind force, the coal powder and particles on the surface are blown away from the car body, which not only causes serious damage to the environment along the railway Pollution also causes a waste of coal resources and brings considerable economic losses to cargo owners. According to statistics, during every 100 kilometers of a train with 30 carriages, nearly two tons of coal will be lost, drifting into the atmosphere we breath...

Problems solved by technology

However, due to its single-dependence on the consolidation effect of polyvinyl alcohol and the influence of the molecular structure and molecular weight of polyvinyl alcohol, it is impossible to obtain a coating with high adhesive strength.

Therefore, the curing time of this adhesive is long, the curing effect is poor, and more dust covering agents are sprayed per compartment (up to 120 kg or more per compartment) which increases the cost
