核孔膜生产线膜微孔制备工艺实验研究

Experimental Study on Preparing Porous Membrane by Production Line of Nuclear Porous Membrane

本文介绍核孔膜生产线,重点描述了膜微孔制备工艺的实验研究。对于PC和PES膜,已得到32种工况下的扩孔公式,其形式为D=A+Bt,其中D——孔径,t——扩孔时间,A,B为特定工艺参数下的常数值.通过实验。得到了膜孔密度N与300~#核反应堆功率P、热柱辐照位置L的经验公式,即N=6.97×10~5×10~3×101^(1.18L).在本生产线上可生产最大幅面为3 140mm×240mm,孔径为0.04～10 μm的多系列多规格的核孔膜产品。

This article presents the production line of nuclear porous membrane in china and especialy describes the experimantal study on preparing the nuclear porous membrane. Under 32experimental condtions a formula used for enlargeng porousness, D=A+Bt, has been given in this paper. Besides, a useful formula, N=6. 97 × 10~5 × P × 10^(1.18L), has aleo been obtained, whare N is the density of nuclear porous membrane, preactor power and Lirradiated location.
