Abstract: front page image
(EN)Provided are heat-resistant inorganic fibers that are suitable for use in a filter material, sealing material, or the like and are highly bio-soluble, with the effects thereof on the human body and living environments minimized even with a mean fiber diameter of 1 µm or less. Said inorganic fibers are characterized by containing, by mass, 35% to 88% Al2O3, 3% to 45% CaO, and 5% to 40% SiO2, with Al2O3, CaO, and SiO2 totaling at least 98% of the mass of the fibers.
(FR)L'invention concerne des fibres inorganiques, résistant à la chaleur, qui sont appropriées pour être utilisées dans un matériau filtrant, un matériau de scellement étanche ou similaires, et qui sont hautement bio-solubles, leurs effets sur le corps humain et les environnements vivants étant rendus minimaux même avec un diamètre moyen de fibre de 1 µm ou moins. Lesdites fibres inorganiques sont caractérisées en ce qu'elles contiennent, en masse, 35 % à 88 % d'Al2O3, 3 % à 45 % de CaO et 5 % à 40 % de SiO2, Al2O3, CaO et SiO2 totalisant au moins 98 % de la masse des fibres.
(JA) 平均繊維径が1μm以下であるものであっても人体や生活環境に及ぼす影響が抑制された、高い生体溶解性を発揮するとともに、フィルター材やシール材等の構成材料として好適な耐熱性を発揮する無機繊維を提供する。 35質量%~88質量%のAl、3質量%~45質量%のCaOおよび5質量%~40質量%のSiOを含み、Al、CaOおよびSiOを合計した含有割合が繊維全体の98質量%以上であることを特徴とする無機繊維である。
