Abstract

The invention relates to a mineral powder railway transportation dust suppressant and a preparation method thereof. The mineral powder railway transportation dust suppressant prevents mineral powder from causing dust pollution in the transportation process. The mineral powder railway transportation dust suppressant comprises the following components in percentage by weight: 0.4 to 0.7 percent of vegetable gelatin, 0.5 to 0.8 percent of modified cellulose, 0.1 to 0.5 percent of lignin and the balance of water. The dust suppressant can be prepared at normal temperature without other heating equipment. After the dust suppressant is prepared at normal temperature, the dust suppressant is sprayed or coated on the surfaces of mineral powder, so that a cured layer can be formed on the surface of the mineral powder, the dust pollution of the mineral powder along a line and the dust loss of the mineral powder in the transportation process are avoided, and the environmental pollution is avoided. The mineral powder railway transportation dust suppressant has great economic benefit and environment-friendly social benefit for mineral powder transportation and mineral powder customers.

Description

technical field [0001] The invention relates to a dust suppressant for mineral powder railway transportation and a preparation method thereof. The dust suppressant is mainly used to prevent the loss and damage of iron ore powder, phosphate rock powder and other mineral powders during railway and road transportation and stacking. pollution of the environment. Background technique [0002] Steel has always occupied an important position in the economic production of all countries. my country has entered the development stage of heavy chemical industrialization, and the rapid economic development has a huge demand for steel. At present, my country's iron ore production areas and smelters have been seriously separated from each other, and my country's iron ore content is not rich. Large quantities are imported from abroad. This creates a transportation problem. Iron ore powder is the main raw material for iron and steel production. Since iron ore powder is powdery, most of the...
