| titleOfInvention | Doughnut membrane preparation method, hollow-fibre membrane and cosolvent compositions |
| abstract | The present invention is about a kind of polysulfones or the preparation method of polyether sulphone hollow fibre film, cosolvent compositions and polysulfones or polyether sulphone hollow fibre film.This preparation method, by polysulfones or polyether sulfone, cosolvent compositions and non-solvent, is prepared as homogenizing preparation liquid；This preparation liquid and core liquid, together by cannula type shower nozzle, enter in cooling bath, compound phase isolated polysulfones or polyether sulphone hollow fibre film occur；Cosolvent compositions in removing hollow-fibre membrane and non-solvent, prepare hollow-fibre membrane.Described cosolvent compositions is gamma butyrolactone, with one or more mixture in ε caprolactone, ε caprolactam, triethyl phosphate and tetramethylurea.This hollow-fibre membrane has high intensity, high separation accuracy and high flux and the chemical-resistance of excellence. |
