Abstract

The invention discloses a dust suppressant for railway transportation of mineral powder and coal and a preparation method of the dust suppressant. The raw materials for preparing effective components of the dust suppressant comprise 39-40% of water-soluble macromolecular polymer, 39-40% of modified cellulose water-soluble polymer or sodium lignin sulfonate, 14-15% of anti-freezing supplementary additive and 5-6% of water-soluble modified additive. During the use, the dust suppressant is uniformly sprayed on the surfaces of railway carriages loaded with coal or mineral powder and forms a curing layer with a certain intensity through the dust suppression principles of moistening and coagulation; and dust is moistened and coagulated in the two dust suppression principles, so that the rising of dust is inhibited, the settlement of dust is accelerated and the purpose of controlling dust pollution is achieved.

Description

technical field [0001] The invention relates to a dust suppressant and a preparation method thereof, in particular to a dust suppressant for railway mineral powder and coal transportation and a preparation method thereof. Background technique [0002] As we all know, dust pollution is one of the world's public hazards. Many human activities will produce dust pollution, especially railway, road transportation and mining. At the same time, the prevention and control of dust is quite difficult and costly. Therefore, for hundreds of years, human beings have never stopped research on the prevention and control of dust. The invention and application of chemical dust suppressants in the 1920s provided a new method for preventing and controlling dust pollution. But so far people have not done enough basic research on chemical dust suppressants, especially in my country's railway transportation, the development and application of chemical dust suppressants started relatively late. ...
