Wetting Characteristics and Microscopic Synergistic Mechanism of Composite Surfactants on Coal Samples with Different Degrees of Metamorphosis

ACS Omega, Год журнала: 2025, Номер 10(6), С. 6105 - 6118

Опубликована: Фев. 10, 2025

This study investigates the effects of composite surfactants on wettability different coal types using a combination macroscopic experiments, mesoscopic and microscopic molecular dynamics simulations, with samples varying degrees metamorphism as research subjects. First, contact angle surface tension experiments were performed at level to determine optimal concentration ratio surfactants. The results showed that solution formed by mixing SLES AEO-9 in 3:2 significantly reduced both mass 0.5 wt %. Second, wetting properties analyzed scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, ζ-potential measurements. revealed total content hydrophobic groups (-CH3, -CH3&-CH2, C=C) molecules was after treatment solution, weakening hydrophobicity samples. Additionally, absolute value potential decreased, enhancing aggregation tendency between particles. facilitated formation larger agglomerated particles, which contributed settling dust. Simultaneously, cracks particles promoted penetration aqueous solutions, aiding seam. Finally, simulations conducted analyze synergistic mechanism level. surfactant effectively adsorbed onto molecules, facilitating movement water surface, increasing diffusion coefficient interaction energy within coal/composite surfactant/water system. These findings provide valuable insights for development new effects, offering significant applications mine dust control.
