本考案はシート状構造体に関し、詳しくは、イオン交換
膜又は濾布のシート状物の両側に多数の細孔を有する弾
性シール材料よりなるシート状ガスケットが配置されて
なるシート状構造体である。[Detailed description of the invention] The present invention relates to a sheet-like structure, and more specifically, a sheet-like gasket made of an elastic sealing material having a large number of pores is arranged on both sides of a sheet-like structure of an ion exchange membrane or a filter cloth. It is a sheet-like structure.

のである。The sheet-like structure of the present invention can be used as a structure of a filter cloth and a sealing material when sandwiching and sealing a filter cloth for the frame of a filter press, or as a structure for a salt electrolytic cell using an ion exchange membrane method using bipolar electrodes. A structure of an ion exchange membrane and sealing material when the ion exchange membrane is sandwiched and sealed between unit battery cells, and an ion exchange membrane and sealing material when the ion exchange membrane is sandwiched and sealed in an ion dialysis tank. It is most suitable for use in the structure of
本考案に訃ける弾性シール材料としては、例えば天然又
は合成のゴム、軟質プラスチック等が用いられる。As the elastic seal material suitable for the present invention, for example, natural or synthetic rubber, soft plastic, etc. are used.
このような材質による場合は、比較的低い締付は圧によ
ってシールすることが可能ではあるが、一般に材質に起
因する永久歪や、クリープ性が大きく、時間の経過によ
り洩漏を生ずるのを防ぐため必要最小限度よりも相当に
強く締付けるのが普通である。In the case of such materials, it is possible to seal with relatively low tightening pressure, but in general, there is permanent distortion and creep property caused by the material, and it is necessary to prevent leakage from occurring over time. It is normal to tighten considerably more strongly than the minimum necessary.
このため、繰返し解体、組み立を行う装置、特に大型の
装置にあ、つてはガスケットの損耗が大きい。For this reason, in equipment that is repeatedly disassembled and reassembled, especially in large equipment, gaskets are subject to significant wear and tear.
更に弾性シール材料は当然締付は時の変形゛が大きいた
め、シート状物を挾持している場合、しばしばガスケッ
トの当り面でシート状物を破損することがある。Furthermore, since the elastic sealing material naturally undergoes large deformation when tightened, when a sheet-like object is being clamped, the sheet-like object is often damaged at the contact surface of the gasket.
本考案におけるガスケットは可及的に締付は圧を低くし
てもなおシール性を良好に保つことができ、しかも締付
は時にガスケットの歪みによる変形量が少なく、該ガス
ケット間に挾持されるシート状物を破損することがない
のが大きな特徴である。The gasket of the present invention can maintain good sealing performance even if the tightening pressure is as low as possible, and in addition, the amount of deformation due to distortion of the gasket is small when tightening, and the gasket is sandwiched between the gaskets. A major feature is that it does not damage the sheet material.
以下本考案の構造及び使用の態様を説明する。The structure and usage of the present invention will be explained below.
第１図は本考案におけるガスケット材料の一例である。FIG. 1 shows an example of the gasket material in the present invention.
弾性シール材料よりなるガスケット１は、シート状ガス
ケットとして有効ないかなる形状をもとり得る。The gasket 1 made of elastic sealing material can take any shape that is useful as a sheet gasket.
本考案におけるシート状ガスケットの細孔２は互に実質
的に連通ずることなくガスケット面に対して実質的に直
角方向に開孔して多数存在している。A large number of pores 2 in the sheet-like gasket according to the present invention are opened in a direction substantially perpendicular to the gasket surface without substantially communicating with each other.
これらの細孔の形状は任意であるが、均一に分布してい
ることが車重しい。Although the shape of these pores is arbitrary, it is important that they are uniformly distributed.
また孔の直径は、一般にガスケットの厚さの１１５乃至
５倍程度が好捷しい。The diameter of the hole is generally preferably about 115 to 5 times the thickness of the gasket.
普た開孔率は一般に５乃至７０％、好捷しくはｌＯ乃至
５０係程度でよい。The open area ratio is generally 5 to 70%, preferably about 10 to 50%.
通常直径２關程度の孔を中心間距離で４關間隔に存在さ
せたもの等が有効である。Usually, it is effective to have holes with a diameter of about 2 squares spaced at 4 square intervals between centers.
勿論孔の形状は円形に限られない。Of course, the shape of the hole is not limited to a circular shape.
例えば第２図の如く楕円形の孔２を有するもの、第３図
の如く、細長い孔を有するもの等がある。For example, there are those that have an oval hole 2 as shown in FIG. 2, and those that have an elongated hole as shown in FIG.
このように円形以外の場合は、主として短径が上記範囲
内にあれば一般に有効である。In this way, shapes other than circular are generally effective if the short axis is within the above range.
また孔径は１ｍｍ以下としてよいし、種々の孔径の孔と
することもできる。Further, the pore diameter may be 1 mm or less, and the pores may have various diameters.
本考案のシート状構造体は、特に大形の装置、例えば濾
過面積が２扉２以上にも及ぶフィルタープレス、イオン
交換膜による電気透析装置或いはイオン交換脱法食塩電
解槽等に供するのに適する。The sheet-like structure of the present invention is particularly suitable for use in large-sized devices, such as a filter press with a filtration area of two or more doors, an electrodialysis device using an ion exchange membrane, or an ion exchange decomposition salt electrolyzer.
このような大型装置で特に多数の単位枠体を重積し、そ
れらの外側から締付けることによって、各単位枠間から
の液体の漏洩を防止するためには、例えば面圧１０ｋｇ
／ｃｍ２以上にも及ぶ締付は圧を必要とする。In order to prevent liquid leakage from between each unit frame by stacking a large number of unit frames on top of each other and tightening them from the outside in such a large device, for example, a surface pressure of 10 kg is required.
Tightening of more than /cm2 requires pressure.
このような強圧によって、ゴム等の弾性シール材は、例
えば第４図矢印ａに示す如く、外側へ向けて７み出すよ
うに変形する。Due to such strong pressure, the elastic sealing material such as rubber is deformed so as to protrude outward by, for example, as shown by arrow a in FIG. 4.
即ち第４図は、イオン交換脱法複極式電解槽の一部を示
す図であり、１がガスケット、３はイオン交換膜、４が
単位電槽（複極枠）である。That is, FIG. 4 is a diagram showing a part of the bipolar electrolytic cell using the ion exchange desorption method, in which 1 is a gasket, 3 is an ion exchange membrane, and 4 is a unit cell (bipolar frame).
このような場合に電槽の外側から、矢印の如く力が加わ
った場合について第５図に示す。FIG. 5 shows a case in which a force is applied from the outside of the battery case as shown by the arrow.
特に外部から力のかからない状態を実線で示し、加圧時
の状態を破線で示す。In particular, the solid line indicates the state where no external force is applied, and the broken line indicates the state when pressure is applied.
即ち、加圧時には単位電槽は破線の位置に進み、シール
材料１は破線で示す如く、外側に孕み出す。That is, when pressurized, the unit container advances to the position shown by the broken line, and the sealing material 1 swells outward as shown by the broken line.
普た一般にガスケットとシート状物は多くの場合滑らな
いため、シール材料の変形に伴って変化する。Gaskets and sheeting generally do not slip in most cases and change as the sealing material deforms.
このため、シート状物のガスケット当り面の長さｔであ
ったものが加圧時には１（ＩｃＵで引き伸ばされること
になる。Therefore, the length t of the gasket contacting surface of the sheet-like material is stretched by 1 (IcU) when pressurized.
次に装置の解体等によって圧力が緩和されると、ガスケ
ットの変形状態は、永久歪分を残して回復する。Next, when the pressure is relieved by disassembling the device or the like, the deformed state of the gasket recovers, leaving behind a permanent strain.
しかしながら、一般にイオン交換膜等シート状物の弾性
回復力は大きくなく、永久歪として蓄積される。However, in general, the elastic recovery force of sheet-like materials such as ion exchange membranes is not large and is accumulated as permanent strain.
従って数度に及び解体、組立ての繰返しによって、シー
ト状物のガスケット当り面は次第に引き伸ばされること
になるか或いは繰り返し引張り力を受けるための疲労の
蓄積により、ついにはシート状物の破損を来たす。Therefore, by repeating disassembly and reassembly several times, the gasket contacting surface of the sheet material becomes gradually stretched, or the sheet material eventually breaks due to the accumulation of fatigue due to repeated tensile force.
しかるに本考案のシート状構造体を用いる場合には、ガ
スケットの変形外がガスケット内にある空胴部に吸収さ
れるため全体として伸ばされる量が著しく小さくなり、
膜の破損はほとんど生じない。However, when using the sheet-like structure of the present invention, the amount of deformation of the gasket is absorbed by the cavity within the gasket, so the amount of stretching as a whole becomes significantly smaller.
Almost no membrane damage occurs.
更に本考案におけるガスケットは、見掛けの面積に比し
て実際に締付は圧を受ける部分が小さくなる。Furthermore, in the gasket according to the present invention, the portion that actually receives pressure during tightening is smaller than its apparent area.
このため、シール効果が大きくなる。This increases the sealing effect.
換言すれば、より小さな締付は圧によって十分なシール
効果が得られるという利点がある。In other words, a smaller tightening has the advantage that a sufficient sealing effect can be achieved by pressure.
