Particles were oriented by a laboratory-size particle orienter, in which many reciprocating plates were set in parallel each other at regular intervals. All boards contained 10% melamine-urea resin and 0.5% wax. All mats contained 10% moisture prior to hot pressing. Press time was 10 minutes at 150℃ and the pressure was 35kg/(cm)^2. The average alinement angle (θ) increased with increasing free fall distance. The percent of particles within 20° to all particles on surface of board could be used as a measure to express the degree of particle alinement. Decreasing the average alinement angle from 40° to 20°increased MOR 40% and MOE 50% in the alined direction. The ratio of <MOR>_∥ to <MOR>_⊥ or <MOR>_∥ to <MOE>_⊥ increased with decreasing free fall distance. The relation of MOE to MOR was well estimated (γ=0.963) for all boards by the equation : MOE=0.178 (MOR)-0.203. Internal bond strength (IB) and thickness swelling increasing with increasing board density and the IB value of highly oriented board (θ : 21°) was somewhat higher than that of the others. Screw-holding strength was not affected by the degree of particle alinement but was more dependent on board density.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062275","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00757373","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"梶田, 煕","creatorNameLang":"ja"},{"creatorName":"カジタ, ヒロム","creatorNameLang":"ja-Kana"},{"creatorName":"Kajita, Hiromu","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"椋代, 純輔","creatorNameLang":"ja"},{"creatorName":"ムクダイ, ジュンスケ","creatorNameLang":"ja-Kana"},{"creatorName":"Mukudai, Junsuke","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"矢田, 茂樹","creatorNameLang":"ja"},{"creatorName":"ヤタ, シゲキ","creatorNameLang":"ja-Kana"},{"creatorName":"Yata, Shigeki","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000079086.pdf","filesize":[{"value":"652.8 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000079086.pdf","url":"https://kpu.repo.nii.ac.jp/record/5087/files/KJ00000079086.pdf"},"version_id":"cda5cd6c-4a9d-4d3c-9112-402df7cc8253"}]},"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"}]},"item_title":"ラワン材を原料とした配向性パーティクルボードの材質(林学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ラワン材を原料とした配向性パーティクルボードの材質(林学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["426"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"5087","relation_version_is_last":true,"title":["ラワン材を原料とした配向性パーティクルボードの材質(林学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-04-10T06:11:52.464088+00:00"}
