METHOD OF PRODUCING A HOLLOW FIBER SEMIPERMEABLE MEMBRANE ELEMENT AND A HOLLOW FIBER SEMIPERMEABLE MEMBRANE ELEMENT. |
摘要 |
<p>There is disclosed a hollow fiber semipermeable membrane element comprising hollow fiber semipermeable membranes having their respective one end portions or both end portions bonded together by means of a vulcanized rubber, so that the semipermeable membrane element has a high resistance to chemicals. The incorporation of a graphite fluoride in the rubber serves to further increase not only the hardness of the bonding rubber portions but also the resistance of the bonding rubber portions to chemicals. Such a semipermeable element can be easily, efficiently produced on a commercial scale.</p> |
