摘要
本文用自制简易透气仪测定中空纤维膜的透气系数和微孔孔径,并与压汞法孔径相比较,结果表明,本法数据基本可靠,重现性良好,可定量地表征中空纤堆膜的结构性质,便利、及时,对中空纤维膜的研究有一定指导意义。
The air permeability and the aperture of the porous hollow fiber were measured by a simple airpermeability device made in our laboratory.The results showed that the data are reliable and well re-produceable comparing with mercury porosimeter.It can quantitatively characterize the structure prop-erties of the porous hollow fiber conveniently and quickly.
