| Summary: | Dust pollution is a major factor contributing to air quality deterioration, and dust suppressants have gained significant attention as an environmentally friendly and effective control measure. However, research on the influencing factors and mechanisms of dust suppressants remains limited. In this study, optical microscopy is employed to compare the dust suppression effects of deionized water (H1), a straw-based dust suppressant (H2), and a commercially available suppressant (H3). The results shows that H2 exhibits excellent water retention capacity, with an evaporation resistance 61.4 times higher than H1 and superior to H3. The mechanism of H2 can be divided into three stages: (1) Water condensation phase (0–60 min), where the water retention agent significantly delays evaporation; (2) Aggregation phase (60–180 min), where fine dust particles aggregate into larger ones due to binder action; and (3) Fiber-forming phase (>180 min), where surfactants create a stable fibrous network between large particles, enhancing solidification. Additionally, it is found that the evaporation rate of H2 is significantly higher in thick soil than in thin soil, suggesting the need for an increased spraying dosage in such conditions. This study elucidates the mechanisms and influencing factors of straw-based dust suppressants, providing theoretical support for their optimization and practical application. |
