METHOD FOR MAKING MEMBRANE APPARATUS BASED ON HOLLOW SEMIPERMEABLE FIBERS FROM POLYMERIC MATERIAL |
摘要 |
A method for producing hollow fiber permeable devices having an essentially leak-free seal between the hollow fibers and the tubesheet that consists of heating the tubesheet containing the hollow fibers potted therein at a temperature essentially equal to or greater than the glass transition temperature of the thermoplastic material or the softening point of the thermoset material of the hollow fiber for a period of time sufficient to essentially densify the hollow fibers in the potted portion of the tubesheet and whereby a major portion of the interior diameter of the bores of the hollow fibers embedded in the tubesheet is enlarged; and the fiber permeable devices themselves. |
