molecular sieving effect

美 [məˈlekjələr ˈsɪvɪŋ ɪˈfekt]英 [məˈlekjələ(r) ˈsɪvɪŋ ɪˈfekt]

1

Molecular sieving effect of the ACF based PAN was found during adsorption .

在吸附时，PAN基ACF呈现出明显的分子筛效应。
2

The molecular sieving effect is spoiled due to the existence of defects in zeolite membranes , resulting in lower separation selectivity .

缺陷的存在降低了分子筛膜的筛分作用和分离选择性，从而限制了其工业应用。

It is considered that a molecular sieving effect of zeolites ( 3A , 4A , 5A ) in EC membranes causes the change of permeation process , then the selectivity is improved .

特别是沸石13X.沸石3A、4A、5A在EC膜中对气体分子筛作用，改变了气体原有的渗透过程，提高了选择性。
