Abstract: Abstract:With the development of science and technology, China's demand for coal has also been increasing. In the process of storage and transportation, it will inevitably produce a lot of dust, not only polluting the environment but also threatening human health. In this study, sodium alginate was used as the grafting matrix. Through the multiple modification of ammonium alginate and the interaction of anionic surfactants, a new environment-friendly dust suppression agent was prepared. Through the study of the relevant properties of dust suppression agent, it was found that the dust suppression agent has excellent performance and good dust suppression effect.
