Description
本発明は複数本の中空糸膜からなり両端部が接着固定層で接着固定され、中空糸膜が露出し、水及び各種水溶液で処理された中空糸膜カートリッジの包装方法に関する。 The present invention relates to a packaging method for a hollow fiber membrane cartridge comprising a plurality of hollow fiber membranes, both ends of which are bonded and fixed by an adhesive fixing layer, the hollow fiber membrane is exposed, and treated with water and various aqueous solutions.
中空糸膜カートリッジは、中空糸膜がケースに収められて接着されたタイプと、ケースがなく両端部が接着剤で接着固定されて中空糸膜が露出したタイプと、が存在する（例えば特許文献１参照）。また、通常、中空糸膜カートリッジは中空糸膜束が現場で直ぐに使用できるように水又は各種水溶液で処理されている。 There are two types of hollow fiber membrane cartridges: a type in which a hollow fiber membrane is accommodated in a case and a type in which there is no case and both ends are bonded and fixed with an adhesive and the hollow fiber membrane is exposed (for example, Patent Documents) 1). In general, the hollow fiber membrane cartridge is treated with water or various aqueous solutions so that the hollow fiber membrane bundle can be used immediately on site.
中空糸膜がケースに収められたタイプの中空糸膜カートリッジは、中空糸膜がケースに収められ接着されているために、保管中及び輸送中の中空糸膜の乾燥及び糸切れの発生はほとんどないが、中空糸膜が露出したタイプの中空糸膜カートリッジは、ケースがなく中空糸膜が露出しているため、保管中及び輸送中に中空糸膜の乾燥や、糸切れの発生等の問題がある。 Hollow fiber membrane cartridges that contain hollow fiber membranes in a case are almost free of drying and breakage of the hollow fiber membranes during storage and transportation because the hollow fiber membranes are contained in a case and bonded. However, hollow fiber membrane cartridges with exposed hollow fiber membranes do not have a case and the hollow fiber membranes are exposed, so problems such as drying of the hollow fiber membranes and occurrence of thread breakage during storage and transportation There is.
本発明は、中空糸膜が露出し、水又は各種水溶液で処理された中空糸膜カートリッジを保管及び輸送時における糸の乾燥及び糸切れを防止するための包装方法に関するものである。 The present invention relates to a packaging method for preventing drying and breakage of yarns during storage and transportation of a hollow fiber membrane cartridge in which a hollow fiber membrane is exposed and treated with water or various aqueous solutions.
本発明者らは、鋭意検討の結果、中空糸膜が露出し、水又は各種水溶液で処理された中空糸膜カートリッジの保管及び輸送時の中空糸膜の乾燥及び糸切れを防止する包装形態として、中空糸膜カートリッジを水蒸気遮断性の袋及びポリエチレン製の袋に挿入して減圧包装することにより保管及び輸送時の中空糸膜の乾燥及び糸切れを防止出来ることを見出し、本発明に至った。 As a packaging form for preventing hollow fiber membranes from drying and thread breakage during storage and transportation of hollow fiber membrane cartridges exposed to water or various aqueous solutions as a result of intensive studies. The present inventors have found that the hollow fiber membrane cartridge can be prevented from drying and breaking of the hollow fiber membrane during storage and transportation by inserting the hollow fiber membrane cartridge into a water vapor blocking bag and a polyethylene bag and packaging under reduced pressure. .
即ち、本発明は以下の通りである。 That is, the present invention is as follows.
複数本の中空糸膜からなり両端部が接着固定層で接着固定され、中空糸膜が露出し、水及び各種水溶液で処理された中空糸膜カートリッジを水蒸気遮断性の袋に収め、更に、水蒸気遮断性の袋に収めた中空糸膜カートリッジをポリエチレンの袋に収め、夫々の袋を減圧して包装することを特徴とする中空糸膜カートリッジの包装方法。 The hollow fiber membrane is composed of a plurality of hollow fiber membranes, and both ends thereof are bonded and fixed with an adhesive fixing layer, the hollow fiber membranes are exposed, and a hollow fiber membrane cartridge treated with water and various aqueous solutions is placed in a water vapor blocking bag. A packaging method for a hollow fiber membrane cartridge, wherein the hollow fiber membrane cartridge housed in a barrier bag is placed in a polyethylene bag, and each bag is decompressed and packaged.
本発明により、中空糸膜が露出し、水及び各種水溶液で処理されたカートリッジの保管及び輸送において中空糸膜の乾燥及び糸切れを防止することが出来る。 According to the present invention, the hollow fiber membrane is exposed, and drying and breakage of the hollow fiber membrane can be prevented in storage and transportation of cartridges treated with water and various aqueous solutions.
本発明の中空糸膜カートリッジの包装方法に適用される中空糸膜カートリッジの構造の一例を図１により説明する。本中空糸膜カートリッジＡは、複数本の中空糸膜からなる中空糸膜束１と、中空糸膜束１の両端にカートリッジヘッド２と下部リング３とを有し、カートリッジヘッド側接着固定層４、及び下部リング側接着固定層５で中空糸膜を固定している。カートリッジヘッド２と下部リング３は側芯棒６により連結されている。
An example of the structure of the hollow fiber membrane cartridge applied to the hollow fiber membrane cartridge packaging method of the present invention will be described with reference to FIG. This hollow fiber membrane cartridge A has a hollow fiber membrane bundle 1 composed of a plurality of hollow fiber membranes, a
この中空糸膜カートリッジＡは、水及び各種水溶液（例えば塩化カルシウム水溶液、グリセリン水溶液等が掲げられる）によって濡れた状態に処理されている。 The hollow fiber membrane cartridge A is treated in a wet state with water and various aqueous solutions (for example, calcium chloride aqueous solution, glycerin aqueous solution, etc.).
本発明の包装方法は、図２に示すように、上記の如く構成された中空糸膜カートリッジＡを、水蒸気遮断性の袋７に挿入して収める。さらに、中空糸膜カートリッジＡを挿入した水蒸気遮断性の袋７をポリエチレン製の袋８に挿入して収めた後、水蒸気遮断性の袋７及びポリエチレン製の袋８それぞれを、上部より減圧した後、ヒートシーラーでシールして減圧包装を行う。減圧包装により中空糸膜束１が袋７、８でしっかり固定され、袋内で中空糸膜が揺れることがなくなる。
In the packaging method of the present invention, as shown in FIG. 2, the hollow fiber membrane cartridge A configured as described above is inserted and stored in a water
特に、水蒸気遮断性の袋７により水の外部への蒸発が防止される。水蒸気遮断性の袋７としては、厚みが０．０３〜０．１ｍｍ程度で水蒸気透過性がＡＳＴＭ−Ｆ１２４９（３８℃ ９０％）の測定で１０ｇ／ｍ2 ・ｄａｙ以下であり、例えば塩化ビニリデン、真空蒸着フィルム等の袋が掲げられるが、これらに限定されるものではない。
In particular, the water
水蒸気遮断性の袋７だけではカートリッジ取り扱い中に傷、こすれ等により破れが発生した場合、中空糸膜カートリッジＡの中空糸膜の乾燥、糸切れを防止が困難である。そのため、水蒸気遮断性の袋７の外側に破れ防止のための厚めの袋を必要とする。
If the water
厚めで減圧により中空糸膜カートリッジＡを固定するためには柔軟性が必要で、素材としてはポリエチレン製の袋８が好適である。ポリエチレン製の袋８の厚みは０．１〜０．３ｍｍが好ましく、減圧包装されることにより、より強固に中空糸膜が固定され、水蒸気遮断性の袋７の傷、破れを防止し、中空糸膜の乾燥及び糸切れを防止できる。
In order to fix the hollow fiber membrane cartridge A with a thick and reduced pressure, flexibility is required, and a
カートリッジヘッド２及び、下部リング３端部による中空糸膜の糸切れを更に防止する為に、カートリッジヘッド２、下部リング３部分に発泡ポリエチレンシート９を巻いて、水蒸気遮断性の袋７、ポリエチレンの袋８を減圧包装することも出来る。
In order to further prevent thread breakage of the hollow fiber membrane due to the
