Problems solved by technology

[0003] (1) Affect the work of departments such as electric services and power supply catenary, because some metal mineral powders transported have conductivity or magnetism, which will affect the normal power supply operation and maintenance operations of the line catenary and insulators of the power supply department;
[0004] (2) Increase the burden on the cleaning and cleaning work of public works and vehicle departments. Many minerals have special properties, such as hematite, which are natural mineral dyes, which are difficult to clean thoroughly after being attached to the surface of locomotives and vehicles;
[0005] (3) Mineral dust pollutes the environment along the line and destroys the ecology along the line. Mineral powders not only contain the required elemental minerals, but some ores also contain many heavy metals and toxic compounds such as cyanide. Seriously destroy the ecology of animals and plants along the line
However, these dust suppressants do not refer to dust suppressants for iron ore fines

Abstract

The invention relates to an iron ore dust suppressant composition, which consists of styrene butadiene latex, a water-soluble polymer material, a surfactant and water. The iron ore dust suppressant can form a cured layer with certain strength and toughness on the surface of iron ore and mineral powder to adhere large, granular and powdery iron ore together, so that iron ore powder can be effectively prevented from flying. The iron ore dust suppressant also can be used for soil desertification prevention, construction site dust prevention and other ore dust prevention, and cannot pollute environment.

Description

【Technical field】 [0001] The invention belongs to the technical field of environmental protection. More specifically, the present invention relates to an iron ore dust suppressant composition. 【Background technique】 [0002] In railway transportation, coal accounts for the largest proportion, followed by various mineral powders, including metallic minerals and non-metallic minerals, such as iron ore, copper ore, lead-zinc ore, iron ore, nickel-cadmium and other heavy metal ore powder . Due to their own characteristics, various mineral powders have small particles and light weight, which will cause dust and loss during transportation, which will bring many problems: [0003] (1) Affecting the work of electrical affairs, power supply catenary and other departments, because some metal mineral powders transported are conductive or magnetic, which will affect the normal power supply operation and maintenance of line catenary and insulators in the power supply department; [00...
