Resumo: Thermal rectification of wood was developed in the decade of 1940 and has been largely studied and produced in Europe. In Brazil, the research about this technique is still little and sparse, but it has gained attention nowadays. The aim of this study was to evaluate the influence of time and temperature of rectification on the reduction of maximum swelling of Eucalyptus grandis wood. According to the results obtained it is possible to achieve reductions of about 50% on the maximum volumetric swelling of Eucalyptus grandis wood. Best results were obtained for 230°C of thermal rectification rather than 200°C. The factor temperature was more significant than time, once that there was no significant difference between the times used (1, 2 and 3 hours). There was no significant interaction between the factors time and temperature.

No Brasil a pesquisa neste tema ainda é pequena e pulverizada, porém vem ganhando destaque atualmente. O objetivo deste trabalho foi avaliar a influência do tempo e da temperatura de modificação térmica na redução do inchamento máximo da madeira de Eucalyptus grandis. De acordo com os resultados obtidos podem-se obter reduções do inchamento volumétrico máximo da madeira de Eucalyptus grandis superiores a 50%. Melhores resultados foram obtidos com a modificação térmica a temperatura de 230°C do que a 200°C. O fator temperatura foi mais significativo do que o fator tempo, uma vez que não houve diferença significativa entre os diferentes tempos utilizados (1, 2 e 3 horas). Não houve interação significativa entre estes fatores na modificação térmica.Universidade Federal de Santa Maria2011-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/381010.5902/198050983810Ciência Florestal; Vol. 21 No. 3 (2011); 533-540Ciência Florestal; v. 21 n. 3 (2011); 533-5401980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3810/2250Batista, Djeison CesarTomaselli, IvanKlitzke, Ricardo Jorgeinfo:eu-repo/semantics/openAccess2017-05-03T17:48:48Zoai:ojs.pkp.sfu.ca:article/3810Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-03T17:48:48Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
