Resumo: Pinus wood is widely used in the forestry industry, mainly in the furniture and civil sectors, so it is important to search for techniques that improve and perfect its technological properties. In this sense, the present study aimed to evaluate the effect of thermal modification on the physical properties of Pinus caribaea var. hondurensis under two different temperatures. Three trees aged 14 years old from the experimental field of the Universidade Estadual do Sudoeste da Bahia, in Vitória da Conquista, BA, were used, of which they were made in samples with dimensions of 30 x 30 x 50 mm. The thermal modification process was carried out in a laboratory oven at 160ºC and 200 ° C of final cycle temperature, which, added to the control, represented three treatments under analysis. The tests of apparent density, humidity, loss of mass, water absorption rate and dimensional stability were performed. It was concluded that the thermal modification altered the physical properties evaluated, making the wood less hygroscopic and with greater dimensional stability, in addition to influencing the color of the wood in relation to its natural appearance.

Neste sentido, o presente estudo teve como objetivo avaliar o efeito da modificação térmica nas propriedades físicas da madeira de Pinus caribaea var. hondurensis sob duas diferentes temperaturas. Foram utilizadas três árvores com idade de 14 anos do campo experimental da Universidade Estadual do Sudoeste da Bahia, em Vitória da Conquista, BA, das quais foram confeccionadas em amostras com dimensões de 30 x 30 x 50 mm. O processo de modificação térmica foi realizado em uma estufa laboratorial a 160ºC e 200°C de temperatura final de ciclo que, somados ao controle, representaram três tratamentos em análise. Foram realizados os ensaios de densidade aparente, umidade, perda de massa, taxa de absorção de água e estabilidade dimensional. Concluiu-se que a modificação térmica alterou as propriedades físicas avaliadas, tornando a madeira menos higroscópica e com maior estabilidade dimensional, além de ter influenciado na coloração da madeira em relação a sua aparência natural.Universidade Federal de Minas Gerais2021-01-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/2659010.35699/2447-6218.2021.26590Agrarian Sciences Journal; Vol. 13 (2021); 1-7Caderno de Ciências Agrárias; v. 13 (2021); 1-72447-62181984-6738reponame:Caderno de Ciências Agrárias (Online)instname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGporhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/26590/23171https://periodicos.ufmg.br/index.php/ccaufmg/article/view/26590/23173Copyright (c) 2021 Caderno de Ciências Agráriashttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccess Santos, Vaniele Bento dos Silva, Gilmar Correia2022-07-20T20:47:03Zoai:periodicos.ufmg.br:article/26590Revistahttps://periodicos.ufmg.br/index.php/ccaufmgPUBhttps://periodicos.ufmg.br/index.php/ccaufmg/oaiccaufmg@ica.ufmg.br2447-62181984-6738opendoar:2022-07-20T20:47:03Caderno de Ciências Agrárias (Online) - Universidade Federal de Minas Gerais (UFMG)false
