| titleOfInvention | Fatty polyamide hollow-fibre membrane and preparation method and application |
| abstract | The present invention relates to technical field of membrane, more particularly to a kind of fatty polyamide hollow-fibre membrane and preparation method and application.The preparation method of the fatty polyamide hollow-fibre membrane, using following step: 1) preparing spinning solution；The spinning solution includes following content of component: 10-30 parts of aliphatic polyamide polymers；1-20 parts of pore-foaming agent；50-90 parts of solvent；2) spinning solution is stood into de-bubble, the spinning solution after de-bubble is heated to 50-70 DEG C, and flows out to coagulating basin through spinneret using wet spinning technology and be frozen into as-spun fibre；The inner core liquid of the spinneret is temperature and the synthermal aqueous solution of spinning solution；Solidification liquid in the coagulating basin is water；3) as-spun fibre of coagulation forming in step 2) is rolled, glycerol impregnates and fatty polyamide hollow-fibre membrane is made in drying.Hollow-fibre membrane of the invention can take into account membrane flux and tensile strength, there is good application prospect. |
