Problems solved by technology

[0004] 1. The dispersibility is not good. If there is no high-speed stirring equipment during the dissolution process of the dust suppressant, it is easy to cause insufficient dissolution, and the solution contains a large number of agglomerates. The effect is seriously reduced, resulting in great waste;
[0005] 2. Poor permeability. Generally, the dust suppressant contains high-molecular plant glue or chemical rubber powder. After the dust suppressant solution is sprayed on the surface of the coal seam, it has a strong surface activit

Abstract

The invention relates to a dust depressor for railway coal transport and a use method of the dust depressor. The dust depressor is prepared from components in parts by weight as follows: 15-25 parts of xanthan gum, 20-38 parts of carboxymethyl cellulose, 10-28 parts of modified starch and 25-40 parts of sesbania gum powder. The dust depressor is prepared from multiple pure natural vegetable gum through refinement and compounding, the problems about dispersity, permeability and dry strength are solved in combination with an instant dissolution technology of the use method, and the dust depressor has a good anti-evaporation characteristic and long service life and can be made into a water solution on the scene to facilitate transportation and spray operation as well as scene operation. Due to the synergistic function of ingredients, the dust depressor has multiple functions on adhesion, wetting and water retention. The preparation method is simple, convenient to operate, low in cost and environment-friendly, facilitates large-scale production, can prevent dust pollution and has an environment protection function.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a dust suppressant for railway coal transportation and a using method thereof. Background technique [0002] In order to solve the problem of loss and pollution caused by natural conditions such as wind erosion, rain and snow in the process of railway coal transportation, people have invented a special dust suppressant for railway coal transportation. Finally, a hard shell can be formed on the surface of the coal seam. This hard shell can not only prevent wind erosion below grade 10, but also prevent losses caused by rain erosion, and also solve the problem of coal powder pollution on both sides of the railway. . [0003] The special dust suppressant for coal transportation currently on the market has the following obvious defects: [0004] 1. The dispersibility is not good. If there is no high-speed stirring equipment during the dissolution process of the dust suppressa...
