Method for manufacturing of ceramic hollow fiber membrane and the ceramic hollow fiber membrane thereby

摘要

The present invention relates to a process for producing a spinning solution by adding a polymer resin to a ceramic solution containing ceramic particles (step 1); (Step 2) of preparing a ceramic hollow fiber precursor by injecting the spinning solution prepared in step 1 into an extruder equipped with a screw, kneading and extruding the hollow fiber membrane precursor through a nozzle for producing a hollow fiber membrane into a coagulation bath containing a coagulant; And sintering the ceramic hollow fiber membrane precursor prepared in step 2 (step 3). The method of producing a ceramic hollow fiber membrane according to the present invention enables mass production using an extrusion method capable of applying high pressure and a phase transfer process and increases the mechanical strength by increasing the content of ceramic powder in a spinning solution . Particularly, even when the hollow fiber membrane is formed with the same ceramic content, excellent mechanical strength is obtained when the membrane is formed by the method according to the present invention.
