PURPOSE: To conduct polymerization in an inert gas atmosphere, to use a solvent-resistant material including fluororesin as a potting material and to produce a highly solvent-resistant hollow-fiber membrane module by shielding the inside of the module from the air outside the hollow-fiber membrane module producing device in injection and curing.
CONSTITUTION: A potting material is centrifugally injected into the end of a hollow-fiber membrane in a module vessel and cured in this device for producing a hollow-fiber membrane module 5, and the inside of the module 5 is shielded from the air outside the device when the potting material is injected and cured. On the other hand, a line 11 for supplying the potting material to the inside shielded from the outside is provided. Further, a vessel 3 is furnished to transiently receive the potting material dripped toward a rotor, and a tube 14 communicating with the module 5 is provided at the bottom of the outer periphery of the vessel 3. Consequently, a material having solvent resistance, etc., or even a material susceptible to the adverse effect by the external air can be used.
