AI Technical Summary

Problems solved by technology

Inorganic substances such as calcium chloride, magnesium chloride, aluminum chloride, sodium sulfate, and water glass are low in cost, easy to use, and have good antifreeze effects, but have poor dust suppression effects, corrode metals, pollute soil, and are not resistant to rain washing
Organic substances such as ethylene glycol, diethylene glycol, and glycerin can infiltrate and adsorb on the surface of dust particles, and have the functions of absorbing water, retaining water, and lowering the freezing point, but they have the disadvantage of poor durability and cannot solve the problem of natural evaporation and rainwater. flushing problem
Coal residue oil, wood residue oil, shale residue oil, light oil, heavy oil, coal tar, blended residue, soft resin and soft asphalt are still low-molecular organic substances, which have good infiltration, adsorption and certainty on the surface of dust particles. The degree of film-forming coating effect is good, and the dust suppression effect is good, but there are obvious safety hazards, which lead to secondary environmental problems
[0005] The existing dust suppressants have the following problems: powder products must be mechanically dispersed into water, otherwise they are easy to clump and cannot be dissolved; liquid dust suppressants are all diluted at 1:20, the dilution ratio is small, the dosage is large, and the cost of use is greatly increased
[0011] The powdery products in the existing dust suppressant must be mechanically dispersed into water, otherwise it is very easy to clump together and cannot be uniformly dispersed; the liquid dust suppressant has a small dilution factor, a large dosage, and greatly increases the cost of use, and the moisture content in the dust suppressant system is relatively high. more, increase shipping cost

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a water-based liquid dust suppressant with a high dilution factor and a preparation and use method thereof. Background technique [0002] The current environmental situation is becoming more and more serious. With the acceleration of urbanization, the dust brought by construction sites, mines and road construction is increasing day by day. Dust suppression nets are usually used now, but the dust suppression nets are plastic products, which are not easy to degrade, and the dust suppression effect on fine dust is limited, and there is secondary pollution during recycling. In addition, all kinds of coal mines, gold mines and other mine storage yards have serious dust pollution problems, which not only pollute the surrounding environment, but also drift with the wind to various places during the transportation process, pollute the ecological environment along the tra...
