Study on preparation and properties of environmentally-friendly dust suppressant with semi-interpenetrating network structure

In order to solve the coal dust pollution generated by open-pit mines, a novel environmentally-friendly poly(vinyl alcohol)/sodium alginate (SA)/glycerol (PVA/SA/GLY) composite dust suppressant was obtained by a simple method in this paper. The formulation of dust suppressant was determined through the orthogonal and single-factor tests. Its properties (viscosity, compressive strength, wetting property, resistance to evaporation and...
