非织造布过滤板的阻力特性研究

Research on Resitance Characteristics of Nonwoven Filterring Board

本文使用介质阻力系数和介质阻力压缩因子两个可比性较强的介质阻力特性参数,对新型过滤介质非织造布过滤板的阻力特性同两种纸质滤板进行了对比研究,其结果表明,非织造布过滤板的介质阻力系数、介质阻力压缩因子及介质阻力系数的周期变化幅度均较小,其阻力特性明显优于纸质滤板。

In this article comparative experiments have been conducted to study the resistance characteristics of the new nonwoven filtering board and the two paper filtering boards by use of two comparative medium resistance parame-ters-the resistance coefficient and the resistance compression factor. The results show that the former's coefficients factor and coefficient periodic changing range are all less than the latter's ones. Therefore, the nonwoven filtering board is suprior to the paper one in the resistance characteristics.
