Abstract

The present invention relates to a hollow fiber membrane module which is provided with a cylindrical case, a hollow fiber membrane bundle composed of multiple hollow fiber membranes enclosed in the cylindrical case and one or more binding parts for binding the multiple hollow fiber membranes, wherein each of the binding parts contains an adhesive agent, the adhesive agent has a glass transition temperature of 80 DEG C or higher and lower than 160 DEG C; and the Mc value represented by a specific formula of the adhesive agent, the weight W of the individual binding parts each of which can bindthe hollow fiber membranes in a state such that the hollow parts of the hollow fiber membranes are opened and the Vicat softening temperature VST of the hollow fiber membranes satisfy a specific formula.

Description

technical field [0001] The present invention relates to a hollow fiber membrane module used in the fields of water treatment, fermentation industry, medicine / medical treatment, food industry, etc., and more specifically, to a hollow fiber membrane module having a binding part with high heat resistance. Moreover, this invention relates to the manufacturing method of this hollow fiber membrane module. Background technique [0002] As seen in Patent Document 1, in general, a hollow fiber membrane module is a hollow fiber membrane bundle in which several hundreds to tens of thousands of hollow fiber membranes are bundled and housed in a cylindrical case, and at least one part of the hollow fiber membrane bundle is One end is bundled and housed in a cylindrical case. [0003] Here, at least one end of the bundled hollow fiber membrane is open, and the hollow portion serves as a flow path for filtrate or filtrate. Here, the bundling part has a function of bundling the membranes ...
