SELECTION METHOD OF ADHESIVE AT ADHERED AND FIXED PORTION OF HOLLOW FIBER MEMBRANE MODULE, MANUFACTURING METHOD OF HOLLOW FIBER MEMBRANE MODULE, AND HOLLOW FIBER MEMBRANE MODULE

摘要

PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module which can suppress breaking of the membrane on an interface with an adhered portion during air washing and back-pressure washing.SOLUTION: Provided is a selection method of an adhesive of the potting resin layer 6 in a hollow fiber membrane module 20 including: a hollow fiber membrane bundle 22 formed of a plurality of hollow fiber membranes 1; a case 2 for storing a whole including an end part of the hollow fiber membrane bundle 22; and a potting resin layer 6 for adhering and fixing the hollow fiber membranes 1 together in the end part of the hollow fiber membrane bundle 22, and the hollow fiber membranes 1 and an inner surface of the case 2. The potting resin layer 6 having the most suitable hardness is selected by selecting hardness of the adhesive of the potting resin layer 6 depending on fracture toughness A of the hollow fiber membranes 1.
