Abstract

The invention discloses an application method of inorganic nano-materials in dust suppression. The inorganic nano-materials are at least one of nanosilicon dioxide, nanometer copper oxide and graphene oxide; in the application method, the inorganic nano-materials are mixed with a solvent to obtain an inorganic nano-material solution, and the inorganic nano-material solution is sprayed on the surface of dust. As is discovered in researches, the inorganic nano-materials are taken as a dust suppressant have good dust solidifying effect; the application method has the advantages that the surface of the dust can be well covered, dust clearance is filled, dust particles are bonded, wind erosion-resistant performance of the dust is improved, and the dust is removed; the dust suppressant has the advantages of no-toxic, no erosion, environment friendliness and the like and is widely applicable to the field of dust suppression, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to an application method of using inorganic nanometer material as a dust suppressant, belonging to the field of environment and dust control. Background technique [0002] Dust is the main pollutant of the atmosphere and one of the main causes of urban smog. Long-term exposure to high-concentration dust will increase the risk of pneumoconiosis, especially some toxic and harmful dust pollution problems are more serious. Chemical dust suppression as a One of the technical means of dust prevention and control, it has been rapidly developed and widely used in industrial production, construction and other fields. A large number of various chemical materials are widely used in the development of dust suppressants, among which the application of surfactants is the most prominent, and has been widely developed. We have developed cationic, anionic, amphoteric, nonionic, polymer and other types of dust suppressants, and have formed a series...
