It is also paid attention as the energy resource of environmental harmony type due to its abundance. A much amount of wood waste is,however, being scraped without being used. Therefore, it is necessary to use the wood waste effectively from a viewpoint of global environmental conservation and zero emission. General heat insulators such as the glass wool, the polystyrene foam and polyurethane foam are being scraped as industrial waste. And environmental disruption of waste materials have been developing rapidly.\nIn this study, wood waste was liquefied by Polyol in the presence of sulfuric acid as a catalyst, and the foam was synthesized by using liquefied wood. In addition, some properties of liquefied wood and physical properties of the foam synthesized in various conditions were evaluated, and compared to that in heat insulator for construction.\nThe viscosity and the hydroxyl value of liquefied wood were controlled by mixing PLACCEL303 and PLACCEL205U used as solvent. The correlation between the thermal conductivity and the density or state of the bubble of foam were investigated. The high foam magnification and low density were subjected to synthesize high thermal insulating properties. We have understood that the thermal conductivity probably increases by the influence of the radiation of heat transmission, even if the density is low. It was found that the uniform and minuteness diameter of the bubble were required to improve the thermal insulating properties.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:15310049, 研究期間(年度):2003-2005","subitem_description_type":"Other"},{"subitem_description":"出典：「木質系廃棄物からの環境調和型高付加価値材料の創製と用途開発」研究成果報告書　課題番号15310049   (KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00049351","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学自然科学研究科"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=60019750"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=60019750","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-15310049/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-15310049/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-15310049/153100492005kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-15310049/153100492005kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-12-11"}],"displaytype":"detail","filename":"TE-PR-HAYASHI-Y-kaken 2006-54p.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-HAYASHI-Y-kaken 2006-54p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/43002/files/TE-PR-HAYASHI-Y-kaken 2006-54p.pdf"},"version_id":"0d253a06-d953-427b-ac06-8943996a1c91"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"木質系廃棄物からの環境調和型高付加価値材料の創製と用途開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"木質系廃棄物からの環境調和型高付加価値材料の創製と用途開発"},{"subitem_title":"The evaluation of physical properties for environmentally feasible product from waste wood and its development of a new use","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2828"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-12-14"},"publish_date":"2017-12-14","publish_status":"0","recid":"43002","relation_version_is_last":true,"title":["木質系廃棄物からの環境調和型高付加価値材料の創製と用途開発"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T14:31:57.153930+00:00"}
