The veneers were dried with a hot press at each of temperatures of 120,150 and 200℃, under no pressure. The wettability of the tight surface of these veneers by water was determined by the sessile drop method, in which photographs were taken through a horizontal microscope of a small water droplet (0.0006ml and about 1mm diameter) at successive time intervals after its introduction onto the veneer surface from a microsyringe. On the other hand, these veneers were glued into 3-ply panels of 6mm total thick ess with the commercial adhesives of urea resin (U), melamine-urea resin (MU), phenol resin (P) and α-olefin resin (α-O). Results obtained are as follows : 1) The wettability of veneers decreased as the drying temperature and time increased. Especially increasing drying temperature from 150 to 200℃ resulted in an increase in the contact angle (Fig. 2). 2) The diameter of droplet on the veneer surface dried at the temperature of 120℃, was almost constant with the lapse of time, but the height of droplet decreased with time in all cases. On the other hand, the diameter of droplet on the overdried veneer decreased with time, that is, this tendency was analogous to that found on paraffin (Figs. 3 and 4). 3) According to the results of contact angle and bond quality, the veneer surface dried at the temperature of 120℃ was appreciably less inactivated. 4) Bonding strength of plywood which made from veneers dried at the temperature of 200℃ decreased with increasing drying time in all cases (Fig. 7). 5) The fractured surfaces produced in shear bonding test specimens of plywood made from veneers which were dried at 200℃ drying temperature and 60 minute drying time, were observed with a seanning electron microscope. These results attested to the lack of bonding between the adhesives and the cell wall.","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":[{}]}]},"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":"KJ00000079023.pdf","filesize":[{"value":"912.3 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000079023.pdf","url":"https://kpu.repo.nii.ac.jp/record/5024/files/KJ00000079023.pdf"},"version_id":"39dbca38-ef8e-42b5-b9d0-8edfd20c7fc5"}]},"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":"レッドセラヤ単板の湿潤性と接着性能に及ぼす乾燥条件の影響(林学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"レッドセラヤ単板の湿潤性と接着性能に及ぼす乾燥条件の影響(林学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["423"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"5024","relation_version_is_last":true,"title":["レッドセラヤ単板の湿潤性と接着性能に及ぼす乾燥条件の影響(林学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-04-10T06:11:53.051959+00:00"}
