| 摘 要： | 首先根据纤维过滤介质的理论假设,对分布密度不同的熔喷纤网进行计算机模拟,然后利用图像分析方法,计算了其孔径大小及其分布并与实际情况对比;在模拟纤网基础上又从理论上计算了占全部孔数10％的大孔对过滤性能产生的影响,并发现经过这10％大孔的流量比例与当量孔径标准差成线性增加的关系。

| Abstract: | Melt blown webs with different fiber distributing density are simulated by the computer, and then their pore size distribution is calculated through the image analysis. Based on this simulated fiber web, the effect of the 10% big pores on the filtration properties is analyzed theoretically. It is found that the flow proportion in these 10% big pores is linearly increased with the standard deviation of the pores equivalent radii. |
