| titleOfInvention | Preparation method of composite hollow fiber membrane |
| abstract | The invention relates to a preparation method of a composite hollow fiber membrane. The preparation method is characterized by comprising the following steps: preparing a membrane casting solution; preparing a core solution and an outer gel bath; utilizing a dry-wet spinning device to inject the core solution and the membrane casting solution into a spinneret together for hollow fiber spinning, and extruding from the spinneret together to prepare a hollow fiber membrane wire; and enabling the hollow fiber membrane wire obtained in the step to pass a dry spinning path of 0-35cm and sequentially enter a first gel bath and a second gel bath for gel phase inversion to form the high polymer hollow fiber porous membrane with a microprous pore canal. The composite hollow fiber membrane prepared by the method disclosed by the invention is a hydrophilic hollow membrane material and has higher membrane flux and good pollution resistance at low pressure; simultaneously, the hollow fiber membrane has better mechanical strength due to the complementary property of the raw materials. |
