Abstract

This technology uses polysulfone as material by adjusting the spinning conditions to produce separation hollow fiber membrane via phase-change wet spinning technique. Hollow fiber membranes thus-produced possesses outer diameter of 800-500mm, inner diameter of 500-300mm, permeation flux of 40-400 L/m2.hr.bar and molecular weight cut-off of 30K?60K。The properties of hollow fiber membrane produce using the technology have met the standard of commerical product of USA and Japan. Moreover, the surface modification of hollow fiber membrane to induce various functions can provide more applications in future.
