多孔滤膜的三种孔径分布及其关联

Three Kinds of Pore Size Distribution in Porous Membrane and Their Relations

本文提出了多孔滤膜的三种孔径分布,推导了不同的孔径分布互相转化的计算公式。并且例证了在微滤(MF)和超滤(UF)技术中,理论上计算分离率R应以ri～yi孔径分布为宜。

Three konds of pore size distribution were proposed and transform formulas of different konds were deduced in this paper. Through the calculation, it was proved that r_i～y_i pore size distribution should be used to count the separation rate in processes of microfiltration and ultrafiltration.
