摘要
对多种表面活性剂的表面张力进行了系统性的表征,依此为基础对非离子/离子型表面活性剂进行复配,获得了具有高效润湿性能的抑尘剂。对比了不同表面张力和固形物含量抑尘剂样品的润湿性能,结果表明,抑尘剂的润湿性能不仅与表面张力有关,还与样品中的固形物含量有关,固形物含量越高,润湿性能越好。工程应用测尘结果显示,喷洒抑尘剂比喷水具有更高的抑尘效率,抑尘剂在降低细小颗粒物的呼吸性粉尘方面更加有效。
The surface tension of various surfactants was systematically characterized. Based on this, the surfactant was compounded to obtain a dust suppressant with high wettability. The wetting prop-erties of the dust suppressant samples with different surface tension and solid content were com-pared. The results show that the wetting properties of the dust suppressant are not only related to the surface tension, but also related to the solid content in the sample. The dust measurement re-sults of the engineering application show that the spray dust suppressant has higher dust sup-pression efficiency than the spray water, and the dust suppressant is more effective in reducing the respiratory dust of fine particles.
