NOZZLE FOR MANUFACTURING A HOLLOW MEMBRANE REINFORCED WITH SUPPORTER AND MANUFACTURING METHOD OF A HOLLOW MEMBRANE REINFORCED WITH SUPPORTER USING THE SAME

摘要

PURPOSE: A nozzle for manufacturing a support reinforcing hollow membrane and a method for the support reinforcing hollow membrane using the same are provided to uniformly coat a separating film on the surface of a blade by controlling the polymer dope penetrability with respect to the blade. CONSTITUTION: An upper nozzle(2) is assembled with the lower side of an assembling body(1). The assembling body is composed of two orifices and a vacuum line which generates vacuum between the orifices. A lower nozzle(3) includes a lower nozzle space part and a polymer dope inlet part. The upper nozzle is inserted into the lower nozzle space part. A hollow path is perforated at the center parts of the two orifices, the upper nozzle, and the lower nozzle.
