Experimental study on ratio optimization and application of improved bonded dust suppressant based on wetting effect

Area of Science:

• Materials Science
• Environmental Engineering
• Chemical Engineering

Background:

• Traditional bonded dust suppressants suffer from poor fluidity and permeability, hindering effective dust layer formation.
• Existing solutions often lack efficiency and economic viability for large-scale applications.

Purpose of the Study:

• To develop an improved bonded dust suppressant with enhanced wetting, flow, and penetration properties.
• To optimize the formulation for superior dust suppression performance and cost-effectiveness.

Main Methods:

• Incorporation of Gemini surfactant to improve wetting and penetration of the dust suppressant solution.
• Selection of polymer absorbent resin (SAP) and sodium carboxymethyl starch (CMS) as primary components.
• Utilizing response surface methodology (RSM) for proportioning optimization based on water loss, moisture retention, wind erosion, and viscosity.

Main Results:

• The novel dust suppressant demonstrated an effective time of ≥15 days, significantly outperforming pure water and comparative agents.
• Achieved a 27.36% reduction in comprehensive cost compared to similar products for mining enterprises.
• Field tests confirmed good dust suppression performance and economic benefits.

Conclusions:

• The developed dust suppressant formulation offers a highly effective and economical solution for dust control.
• The study highlights the importance of improved wetting performance in optimizing bonded dust suppressants.
• This research provides a foundation for developing advanced dust control technologies, reducing environmental hazards and occupational diseases.
