(JA) ダイヤフラムおよび往復動ポンプ
Abstract: front page image
(EN) Provided is a diaphragm having excellent corrosion resistance and durability with respect to liquids containing oxidizing substances. This diaphragm (100), which undergoes reciprocal motion and is used to transport a liquid (50), is equipped with: a nonporous film (14) formed from a fluorine-based resin; a rubber film member (10) laminated on the nonporous film (14); and a gas barrier film (12) arranged between the rubber film member (10) and the nonporous film (14). The nonporous film (14) and the gas barrier film (12) are bonded together by thermo-compression bonding.
(FR) L'invention fournit un diaphragme qui se révèle excellent en termes de durabilité et de résistance à la corrosion vis-à-vis d'un liquide contenant un oxydant. Plus précisément, l'invention concerne un diaphragme (100) mis en œuvre afin d'imposer un mouvement de va-et-vient pour convoyer un fluide (50), et équipé : d'une membrane non-poreuse (14) configurée par une résine fluorée ; d'un élément membrane de caoutchouc (10) stratifié sur la membrane non-poreuse (14) ; et d'une membrane de barrière au gaz (12) disposée entre l'élément membrane de caoutchouc (10) et la membrane non-poreuse (14). La membrane non-poreuse (14) et la membrane de barrière au gaz (12) sont liées par thermocompression.
(JA)  酸化性物質を含む液体に対する耐食性・耐久性に優れたダイヤフラムを提供する。往復動させて流体50を搬送するために用いられるダイヤフラム100であって、フッ素系樹脂から構成された非多孔膜14と、非多孔膜14に積層されたゴム膜部材10と、ゴム膜部材10と非多孔膜14との間に配置されたガスバリア膜12とを備え、非多孔膜14とガスバリア膜12とは熱圧着によって接合されている、ダイヤフラムである。
