摘要
探讨窗帘布含水率对空气中细颗粒物沉积性能的影响状况。在定制的密闭小室内进行实验,获得了不同粒径的颗粒物在样品布表面不同含水率下的沉积损失率。实验结果表明:颗粒物沉积损失率随粒径的增大呈V型变化,颗粒物的沉积损失率随样品含水率的增加整体呈现降低的趋势;在相同含水率下,不同粒径的颗粒物在麻样品表面的沉积损失率大于涤纶样品。
In order to analyze the effect of curtain cloth moisture content on the deposition performance of fine particles in air,the deposition loss rate of particles with different particle sizes under different moisture content of curtain samples were obtained by the test in a specific designed closed chamber.The experimental results show that the particle deposition loss rate curves are V-shaped with the increase of particle size,and the deposition loss rate of particles decrease with the increase of moisture content.Under the same moisture content,the deposition loss rate of particles with different particle sizes on the surface of hemp samples are greater than those of polyester samples.
