But CO_2 and mold bonded with sodium silicate has difficulty in collapsibility because of its too high residual strength after heating at high temperaturse. Generally speaking the rseidual strength of this mold hsd been considered to depend on sodium silicate which is unconcerned in the chemical reaction between sodium silicate and calcium salt silicate. Therefore, it is expected that the residual strength of this mold will be influenced by varying the temperature and the humidity. In this experiment, we studied the effecst of the temperature, the humidity and the collapsing materials i.e., bentonite, pitch, glyoxal on the residual strength of self-hardening mold. The results obtained are as follows. \n(1) The residual strength decrease as the temperature rsise. \n(2) The residual strength increases as thehumidity lowers. \n(3) When the collapsing materiasl are added to self-hardening mold the residual strength of self-hardening mold and its collapsibility decrease.","subitem_description_type":"Abstract"},{"subitem_description":"けい酸ソーダとけい酸カルシウムを粘結剤とした鋳型はCO_2型より良い長所がある。CO_2型の欠点すなわち，けい酸ソーダを粘結剤とした鋳型は鋳込み後の残留強度が非常に高いため崩壊性は困難となる。\n一般的にいうと，この鋳型の残留強度はけい酸ソーダとけい酸カルシウムとの化学反応に寄与しなかったけい酸ソーダによって関係するものと予想される。従って，この鋳型の残留強度は気温，湿度の変化によって影響するものと考えられる。本実験は，自硬性鋳型に及ぽす気温，湿度と崩壊材（ベントナイト，ピッチ，グリオキザール）の影響について検討した。\n得られた結果は次のとおりである。 \n1) 気温が高くなると残留張度は低下する。 \n2) 湿度が低くなると残留強度が高くなる。 \n3) 崩壊材を添加すると，自硬性鋳型の残留強度は低下し，崩壊性が改善される。","subitem_description_type":"Abstract"}]},"item_3_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_3_description_6":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"富山大学工学部紀要，25","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"56273","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YOHDA, Minoru"}]},{"nameIdentifiers":[{"nameIdentifier":"56274","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YOSHIMOTO, Takashi"}]},{"nameIdentifiers":[{"nameIdentifier":"56275","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NAKADA, Toshio"}]}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15099/00004137","subitem_identifier_reg_type":"JaLC"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"富山大学工学部"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00175872","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03871339","subitem_source_identifier_type":"ISSN"}]},"item_3_subject_22":{"attribute_name":"国立国会図書館分類","attribute_value_mlt":[{"subitem_subject":"ZM2","subitem_subject_scheme":"NDLC"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"養田, 実"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"吉本, 隆志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中田, 登志夫"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-16"}],"displaytype":"detail","filename":"Kokiyo_25_01_Page028to034.pdf","filesize":[{"value":"4.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Kokiyo_25_01_Page028to034.pdf","url":"https://toyama.repo.nii.ac.jp/record/4143/files/Kokiyo_25_01_Page028to034.pdf"},"version_id":"4e9e1c15-3cb9-4061-ba11-a069cb6fc4ce"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"自硬性鋳型","subitem_subject_scheme":"Other"},{"subitem_subject":"残留強度","subitem_subject_scheme":"Other"},{"subitem_subject":"けい酸ソーダ","subitem_subject_scheme":"Other"},{"subitem_subject":"けい酸カルシウム","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"自硬性鋳型の残留強度に及ぼす気温,湿度の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"自硬性鋳型の残留強度に及ぼす気温,湿度の影響"}]},"item_type_id":"3","owner":"3","path":["585"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-09-27"},"publish_date":"2012-09-27","publish_status":"0","recid":"4143","relation_version_is_last":true,"title":["自硬性鋳型の残留強度に及ぼす気温,湿度の影響"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-25T15:11:42.622807+00:00"}
