中空纤维膜组件及其制造方法
摘要：
本发明的中空纤维膜组件具有：筒状容器(2)，其一端部和另一端部都开口；中空纤维膜束(3)，其被装填在该筒状容器(2)中；灌封部(4)，其在筒状容器(2)的两端部将中空纤维膜束(3)包埋起来并将中空纤维膜束(3)固定在筒状容器(2)的两端部；及帽(5)，其设于筒状容器(2)的两端部，且具有成为流体出入口的嘴部。该中空纤维膜组件中，帽(5)和筒状容器(2)在至少一次焊接部(71)和二次焊接部(72)这两处区域被焊接在一起，二次焊接部(72)配置在能够在一次焊接部(71)的焊接开始后开始焊接的位置或能够在一次焊接部(71)的焊接开始的同时开始焊接的位置。
摘要（英）：

The hollow fiber membrane module pertaining to the present invention is provided with: a cylindrical container (2) in which one end part and the other end part thereof are open; a hollow fiber membrane bundle (3) loaded in the cylindrical container (2); a potting part (4) in which the hollow fiber membrane bundle (3) is embedded and fixed in both end parts of the cylindrical container (2); and a header (5) having a nozzle as a fluid exit/entrance, the header (5) being provided to both end parts of the cylindrical container (2). In the hollow fiber membrane module, the header (5) and the cylindrical container (2) are welded in at least the two locations of a primary weld part (71) and a secondary weld part (72), the secondary weld part (72) being disposed in a position at which welding is initiated after or at the same time as the start of welding of the primary weld part (71).
