A multiscale study on the molecular mechanisms of surfactants that enhance the wettability of coal dust and the efficiency of droplet coagulation
Shandong University of Science and Technology · National University of Singapore
Abstract
Surfactants are widely applied in mine dust control; however, the intrinsic mechanism by which microscopic physicochemical properties determine macroscopic wetting performance remains not fully elucidated, limiting the rational design of high-efficiency reagents. To address this, this study employs a multi-scale approach integrating macroscale experiments, mesoscale dust-droplet collision modeling, and molecular dynamics simulations to systematically reveal the wetting performance differences and multiscale mechanisms of four typical surfactants: SDS, AES, APG, and DTAB. Macroscale experiments, including surface tension measurements and spray-based dust suppression tests, established the wetting performance…
