| titleOfInvention | Production of composite semipermeable membrane |
| abstract | PURPOSE: To obtain a composite semipermeable membrane of improved rate of water permeation and rate of removal in the heat treatment stage after the reaction of the reactive substrate coated on a porous supporting membrane with a crosslinking agent by blowing air at specific different velocities of wind to the front and rear surfaces of the membrane. n CONSTITUTION: A membrane 10 prepd. by coating or impregnating a reactive substrate consisting of a monomer, oligomer and polymer having 2 pieces of functional groups such as amino groups or hydroxyl groups in one molecule on or with a porous supporting-membrane and causing the reactive substrate to crosslink and polymerize with a crosslinking agent such as isophthaloyl chloride or terephthaloyl chloride is mounted to a partition wall 8 by directing its front surface toward a blasting chamber 5 and its rear surface toward a blasting chamber 6 in such a way as to close a through-hole 7. Hot wind is fed into the respective blasting chambers by means of a fan 9 under controlling of the aperture areas of the side surfaces of the respective chambers to 0.1W 5m/sec velocities of wind in the chamber 5 and 0.7W2.5m/sec in the chamber 6 as well as to 3W10 ratios of the velocity of wind on the rear surface of the membrane to the velocity of wind on the front surface of the membrane, whereby heat treatment is accomplished. In this way, the composite semipermeable membrane of high rate of water permeation and rate of removal is obtained. n COPYRIGHT: (C)1982,JPO&Japio |
