The strengthening of this mold has been considered probably to depend upon the chemical reaction between sodium silicate and dicalcium silicate, and the removal of the water from the sodium silicate solution retaining in molding sand without undergoing the selt-hardening reaction. Therefore, it is expected that the characteristics of this mold will be influenced by varying the temperature and humididy. In this experiment we studied the effects of the temperature and humidity on the various properties of self-hardening mold, (ie, the compressive strength, the surface safety intensity, the residual moisture) The results obtained are as follows; \n(1) The most favorable time of mixing is shortened as the temperature rises. \n(2) The compressive strength of this mold increases as the humidity lowers. \n(3) The surface safety intensity becomes inadequate as tne humidity lowers. \n(4) The higher the temperature, the fewer the residual moisture, and the higher the humidity, the more the residual moisture.","subitem_description_type":"Abstract"},{"subitem_description":"従来けい酸ソーダとけい酸カルシウム塩による自硬性鋳型に関する数多くの研究が，多くの研究室で種々の観点からなされてきた。\n本鋳型の強度発生の理由は，けい酸ソーダとけい酸カルシウムとの間の化学反応と，その反応に与らなかった未反応けい酸ソーダからの水分の離脱に依存したものであろうというふうに考えられている。\n従って本鋳型の諸特性は，気温，湿度が変化することによって変動することが予想される。本実験では，自硬性鋳型の諸性質（圧縮強さ，SSI，残留水分）におよぽす気温，温度の影響について研究した。\n得られた結果は次のとおりである。 \n(1) 最適混練時間は、気温が高くなるにつれて短縮された。 \n(2) 圧縮強さは，湿度が低くなるにつれて増加した。 \n(3) 表面安定度は，湿度が低くなるにつれて不十分となった。 \n(4) 気温が高くなるほど残留水分は，少なくなりまた湿度が高いほど多くなった。","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，24(1/2)","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"56190","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YOHDA, Minoru"}]},{"nameIdentifiers":[{"nameIdentifier":"56191","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YOSHIMOTO, Takashi"}]}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15099/00004112","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":[{}]}]},"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_24_01_Page020to031.pdf","filesize":[{"value":"3.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Kokiyo_24_01_Page020to031.pdf","url":"https://toyama.repo.nii.ac.jp/record/4118/files/Kokiyo_24_01_Page020to031.pdf"},"version_id":"a1aad598-c173-45da-a851-53d3ac913f61"}]},"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":"自硬性鋳型の特性","subitem_subject_scheme":"Other"},{"subitem_subject":"気温,湿度の影響","subitem_subject_scheme":"Other"},{"subitem_subject":"最適混練時間","subitem_subject_scheme":"Other"},{"subitem_subject":"残留水分","subitem_subject_scheme":"Other"},{"subitem_subject":"圧縮強さ","subitem_subject_scheme":"Other"},{"subitem_subject":"SSI","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":"自硬性鋳型の特性におよぼす気温,湿度の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"自硬性鋳型の特性におよぼす気温,湿度の影響"}]},"item_type_id":"3","owner":"3","path":["584"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-09-27"},"publish_date":"2012-09-27","publish_status":"0","recid":"4118","relation_version_is_last":true,"title":["自硬性鋳型の特性におよぼす気温,湿度の影響"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-25T15:11:57.287897+00:00"}
