the smaller the diameter of filtration medium was, the bigger the brownian diffusion deposition and smaller the filtration efficiency were.
过滤介质的粒径越小,粒子的扩散沉积效应越高,穿透率也就越低。
parameters, such as smoke filtration velocity, filtration medium thickness and rinsing fluid with respect to quantity and concentration, are to be determined through simulation tests.
the present invention provides an anti-pathogenic air filtration medium comprising a fibrous substrate whose fibers are coated with coating comprising a polymer.
本发明提供了一种含纤维底物的抗致病性空气过滤介质,其中的纤维被含有聚合物的涂层涂覆。
from the data listed in table 3, 4, 5, it can be seen that the filtration medium has high filtration efficiency and high filtration accuracy.
由表三、四、五所列数据可以看出,这种过滤介质的过滤效率很高,过滤精度也很高。
the advent of the metal fibre sintering felt is a right solution for some lacked filtration characteristics of the existing filtration medium available.
