Preparation and Application of Polymer Dust Suppressants in Coal Transportation under Microwave Irradiation

Abstract:

The aqueous solution polymerization of acrylic acid, acryl amide and oxidized starch under microwave irradiation was studied, and a polymer dust suppressants was synthesized. It just needs 2 mins to preparation it. The polymer dust suppressants were characterized by IR and scanning electron microscopy (SEM). Prepared several coal models by polymer dust suppressants solution (2.0 g/L) was mixed with coal, and to determine compressive strength, temperature resistance, wind corrosion resistance and water corrosion resistance. The result showed that the polymer dust suppressant can effectively reduce the coal loss and particle pollution in transportation.
