AI Technical Summary

Technical Problem

Existing dust suppressants suffer from problems such as narrow applicability, limited functionality, unsatisfactory adhesion and dust suppression effects, high price, and easy secondary pollution.

Method used

A combination of lignite extract, ionic surfactant, and nonionic surfactant is used. After emulsification and dilution, the mixture is sprayed onto the surface of coal, utilizing its adhesiveness and affinity to form a crust layer to suppress dust.

Benefits of technology

It achieves a highly efficient dust suppression effect that is widely applicable, non-toxic, and pollution-free, with low cost and suitability for industrial applications.
