Problems solved by technology

my country began to promote wetting agents in the 1980s. Domestically produced wetting agents mainly include HJ-I from Ganzhou, Jiangxi, sDLY from the Ministry of Water and Electricity, sR-l from Shanxi, and H-86 from Fengtai, Beijing. The disadvantage is that each wetting agent The scope of application is very small

Abstract

The invention relates to a high-efficiency wet-type dust suppressant for treating dust, and a preparation and using method of the dust suppressant, and belongs to the field of environmental protection. The high-efficiency wet-type dust suppressant for treating dust is composed of the following components in parts by weight: 10-60 parts of a mixed surfactant, 30-70 parts of a wetting agent, 5-20 parts of a moisture absorption agent, 1-5 parts of a preservative and 5-20 parts of water, wherein the mixed surfactant is a mixture of a fatty alcohol-polyoxyethylene ether, a heterogenous fatty alcohol-polyoxyethylene ether, a dicyclohexyl sulfosuccinate sodium salt and an organic silicon surfactant, the wetting agent is a mixture of a heterogeneous alcohol and a heterogeneous fatty alcohol-polyoxyethylene ether, and the moisture absorbent is a mixture of polyethylene glycol and glycerol. The high-efficiency wet-type dust suppressant for treating the dust provided by the invention is a novel moisture-preserving wet-type dust suppressant with ultra-low surface tension, long-lasting wettability and long-term moisture absorption and moisture retention, can greatly improve the dust suppressionefficiency, prevent dust from raising, and meet the requirement of energy conservation and environmental protection.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a high-efficiency wetting dust suppressant for dust control and a preparation and use method thereof. Background technique [0002] Many human activities will produce fine particles or dust, and dust pollution accounts for a large proportion of air pollution. For example, thermal power plants, heating plants, mining sites, quarries, cement plants, stone processing plants, non-ferrous and ferrous metal smelters, textile mills, chemical plants, asphalt plants, etc. are the main sources of dust production. Dust from construction sites, open-air bulk material storage yards, and bare dry land is very serious. Dust pollution has many impacts on humans and the environment, such as poisoning and irritation to humans, reducing visibility, causing wear and corrosion of equipment, causing damage to crops, grasslands, and livestock growth, and has a very prominent impact on...
