る。 FIG. 1 shows an example of the assembly structure of the spiral type membrane separation body used in the present invention, in which a porous sheet-like permeate channel material 2 is attached to a permeate collection pipe 1 having a plurality of small holes. Glue the starting end of the
On this permeate flow path material 2, a stock solution flow path material 4 of, for example, a net-like plastic sheet is placed between the selectively permeable membrane 3 which is folded in half. Next, after applying adhesive 5 to both edges of the permeate channel material 2 at the start of winding, both edges of the selective permeable membrane 3', and the end of the winding, these materials are placed around the permeate collection pipe 1. By winding and gluing each part, a membrane envelope is formed in which both sides of the permeate channel material 2 are sandwiched by the selectively permeable membrane 3, three sides are adhesive-sealed, and the remaining side is open. In this way, the open end of the membrane envelope is communicated with the permeate collection pipe 1,
A spiral-type membrane separation body A is formed by disposing a stock solution channel material 4 between adjacent membrane envelopes.

ゆるんでしまうという欠点もあつた。 Conventionally, as shown in FIG. 2, the spiral type membrane separation main body A constructed in this manner has an adhesive tape 6 wrapped around its outer circumferential surface to prevent the membrane separation main body A from loosening and resulting in poor sealing. However, when the stock solution is subjected to membrane separation treatment, the adhesive layer 7 of the adhesive tape 6 is in contact with the stock solution, resulting in an inconvenient phenomenon in which impurities such as adhesive components are eluted into the permeated liquid. Especially when used in fields that require extremely high purity water, such as ultrapure water manufacturing processes, the increase in purity is slow and it takes a long time to reach the desired purity, resulting in high processing costs. It had the disadvantage of becoming. Furthermore, when continuous operation was performed for a long period of time, the tape peeled off and the membrane separation main body A became loose.

択することができる。 The heat-shrinkable tube in the present invention is not particularly limited as long as it does not elute impurities into the permeate; for example, a single-layer heat-shrinkable tube made of polyvinyl chloride, polyethylene, or polypropylene is preferably used, and in particular A material that does not contain eluates such as plasticizers, softeners, and dyes is used. Further, the thickness of the membrane is approximately 0.05 to 0.5 mm, which is practically used, and can be appropriately selected as long as it contracts at a temperature that does not deform the membrane separation body upon heating.
