Application Scope: 1. Environmental dust control on construction and demolition sites, reducing dust pollution; dust and temperature reduction on hydraulic dams, road bridges, etc. 2. Dust pollution control in coal selection yards, mining areas, coal piles, port coal yards, power plants, steel mills, coke plants, etc. 3. Large-scale disinfection and epidemic prevention in garbage piles and after natural disasters. With the continuous development of the construction industry, it has promoted economic growth to some extent, but has also brought severe environmental pollution around, particularly dust pollution. Data shows: dust pollution is one of the major causes of urban air pollution, and its contribution to PM2.5 can reach up to 30% during severe pollution. Air pollution and smoggy weather have become a threat to the "biosphere." Smog consists of particles such as PM2.5, dust, and aerosols floating in the air, which form a weather phenomenon under certain humidity and temperature conditions in a relatively stable state. Air pollution has become a threat to human health, especially smoggy weather caused by PM2.5 particles. It severely affects physical and mental health and daily life, and has become one of the main disasters threatening human health. Smog disasters are the result of long-term air pollution. How to control air pollution is one of the urgent issues facing humanity.
