Abstract: front page image
(EN)This invention provides an ozone gas detecting element (102) comprising a porous body (121), which is porous glass with a plurality of micropores (122) having an average pore diameter of 4 μm, a detecting agent (123) provided within the pore (122), and a selective transmission film (124) which is formed of a plastic film and is provided so as to cover the surface of the porous body (121). The selective transmission film (124) is formed of, for example, an organic polymer prepared using, as a monomer, a compound of a vinyl-containing chain molecule, such as polyacrylonitrile or PMMA and has a thickness of about 0.05 μm to 1 μm.
(FR)Cette invention a pour objet un élément de détection de gaz ozone (102) comprenant un corps poreux (121), composé de verre poreux et d’une pluralité de micropores (122) dont le diamètre moyen est de 4 µm, un agent détecteur (123) placé au sein du pore (122), et une pellicule de transmission sélective (124) formée d’un film plastique et servant à recouvrir la surface du corps poreux (121). Cette pellicule de transmission sélective (124) est composée, par exemple, d’un polymère organique préparé, en tant que monomère, au moyen d’un composé de molécule en chaîne vinylique, comme du polyacrilonitrile ou du polyméthacrylate de méthyle, et dont l’épaisseur est comprise entre 0,05 µm et 1 µm.
(JA) 検知素子(102)を、平均穴径が4μmの複数の微細な孔(122)を備えた多孔質ガラスである多孔体(121)と、孔(122)内に設けられた検知剤(123)と、多孔体(121)の表面を覆うように形成されたプラスチック被膜からなる選択透過膜(124)とから構成する。選択透過膜(124)は、例えば、ポリアクリロニトリルやPMMAなどのビニル基を含む鎖状分子からなる化合物を単量体とした有機高分子から構成されたものであり、膜厚0.05μm~1μm程度に形成された状態とする。
