Embodiment 1

[0084] 10,000 (±500) polysulfone hollow fiber membranes with an outer diameter of 255 μm were bundled to prepare a hollow fiber membrane bundle with a diameter of 45 mm and a length of 305 mm. As the cylindrical portion, a polystyrene resin container having a total length of 286 mm was provided with two nozzles (fluid passing portions) for inflow / outflow of fluid near both ends. like figure 1 As shown, the height difference H1 between the end surface of the inner cylinder part and the end surface of the outer cylinder part made of polypropylene is 8.0 mm (the height from the bottom surface of the groove to the end surface of the outer cylinder part is 11.0 mm, and the height from the bottom surface of the groove is 11.0 mm. The height to the end surface of the inner cylinder part is 3.0mm), and the gap filling tool with the maximum groove width T1 of 3.0mm is installed on both ends of the cylindrical part, and the hollow fiber membrane bundle is loaded into the tube with the ...

Embodiment 2

[0087] Samples were produced under the same conditions as in Example 1 except that the exposed distance of both ends of the hollow fiber membrane bundle from the end face of the inner cylinder was 1.0 mm or more and the viscosity of the caulk was 8000 mmPa·s.

Embodiment 3

[0089] In addition to the fact that the exposed distance of both ends of the hollow fiber membrane bundle from the end surface of the inner cylinder is 1.0 mm or more, the viscosity of the caulk is 3000 mmPa·s, and the maximum groove width T1 is 4.0 mm. Samples were produced under the same conditions as in Example 1.

Abstract

The invention provides a calking appliance and a manufacturing method for a fluid processor. The calking appliance is able to inhibit usage amount of the calking material and inhibit usage amount of a sealant. When an opening end of a hollow fiber film beam (A) included a barrel-shaped portion (10) of a fluid processor (1) is calked by means of the calking material (E) during manufacturing the fluid processor (1), the calking appliance (30) is mounted on the end portion of the barrel-shaped portion (10). The calking appliance (30) is in a barrel shape. The inner side of a barrel-shaped outer circumferential wall (40) forms a groove (41) along the outer circumferential wall (40), wherein the groove (41) is opened towards the axial direction only. The calking appliance (30) includes an outer barrel portion (50), an inner barrel portion (51), a bottom portion (52) and an embedding portion (53). The end portion of the outer barrel portion (50) is projecting more than that of the inner barrel portion (51). The groove (41) is equipped between the outer barrel portion (50) and the inner barrel portion (51).

Description

technical field [0001] The present invention relates to a caulking tool and a method for manufacturing a fluid processor using the caulking tool. When caulking is performed at both ends of the hollow fiber membrane bundle in the section, the caulking tool is installed at the end of the cylindrical section. Background technique [0002] In recent years, fluid processors using hollow fiber membranes have been widely used in various fields such as industrial fields such as water treatment and gas separation, and medical fields such as blood treatment, especially as water purifiers, artificial kidneys, artificial lungs, etc. , greatly increasing the demand for the fluid handler. [0003] Generally, when manufacturing the above-mentioned fluid processor, such a potting process is performed, that is, after the hollow fiber membrane bundle is packed into the inside of the cylindrical part of the fluid processor, the cylindrical part and the hollow fiber membrane bundle are Both e...
