Hollow fiber membrane module and leak durability test method for hollow fiber membrane module

摘要

PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module capable of suppressing generation of cracks in a sealant accompanying the shrinkage of a hollow fiber membrane even if a thermal load is applied over a plurality of times.SOLUTION: A glass-transition temperature of sealants 16A and 16B is set lower than the lower limit of a test temperature range in a leakage durability test against a thermal load.SELECTED DRAWING: Figure 1
