Deodorizing Ability of a Diatomaceous Material as an Environmentally-Friendly Inner-Wallboard. 健康建材として用いられている珪藻土質材料の脱臭能の評価 Kanno, Toru KAWAMURA, Keisuke TADA, Kiyoshi HORIUCH, Jun-ichi KOBAYASHI, Masayoshi open access Deodorizing ability of a diatomaceous material mined from Wakkanai district in Hokkaido Pref. was examined in detail. This material is widely distributed in the market as a material of environmentally-friendly inner-wallboard. Alternative introductions of a model odor {NH3, CH3CHO, or (CH3)2S} mixed-N2 gas flow and a pure N2 gas flow into the diatomaceous material showed reversible adsorption and desorption of the odor components at 25°C, reconfirming regeneration of deodorizing ability for the diatomaceous-wallboard by ventilation of rooms with these wallboards. The adsorbed quantities of the odors onto the diatomaceous material during one hour readily cleared the odor level 3:2.3ppm for NH3, 0.14ppm for CH3CHO, and 0.044ppm for (CH3)2S, respectively. 和文タイトルが「健康建材として用いられているケイ質頁岩材料の脱臭能の評価」から「健康建材として用いられている珪藻土質材料の脱臭能の評価」に変更になった（2002 年 110 巻 1282 号 p. e2 に掲載） 日本セラミックス協会 2002 eng journal article VoR https://kitami-it.repo.nii.ac.jp/records/8786 https://doi.org/10.2109/jcersj.110.243 1882-1022 Journal of the Ceramic Society of Japan 110 1280 243 247 https://kitami-it.repo.nii.ac.jp/record/8786/files/J.of the Ceramic Society of Japan 110 [4] 243-247 (2002).pdf application/pdf 2.0 MB 2019-11-01
