- (1)
- A new formulation of nano-composite dust suppressant was proposed. The nanofluid dust suppressant has high-efficiency adsorption performance, which can effectively agglomerate surrounding dust particles, but it is poor in wetting and moisturizing functions from the mechanism of dust suppression. The traditional components of dust suppressant were proposed to improve the comprehensive performance of nanofluid dust suppressant. The nanometer material , super absorbent polymer, carboxyl methyl starch sodium, and polyacrylamide were selected as effective components of the nano-composite dust suppressant. The experimental results show that the surface tension of solution and water loss rates of nano-composite dust suppressants, respectively, decreased by 31.96% and 7.1%, the maximum UCS increased by 31.82% compared with data of nanofluid dust suppressant.

- The nano-composite dust suppressant has multiple dust suppression effects. The nano-composite dust suppressant has good dispersion, permeability, and bond performance, and the suppressant film has fewer micro-cracks from the photos of microscopic image. The nanoparticles can adsorb and bond the surrounding dust particles and improve the overall integrity and strength of the suppressant film, the traditional components can improve the moisturizing performance and consolidation ability compared with nanofluid dust suppressant, and the dense film can prevent the evaporation of water and dust re-entrainment. The comprehensive dust suppression effect of nano-composite dust suppressant has been significantly improved.
