Resumo: | The aim of this study was to evaluate the effect of boron compounds utilized in wood impregnation, its influence on the physical properties of eucalyptus wood and to verify the veracity of the equilibrium moisture content obtained by the Simpson’s equation. The wood impregnation consisted of 4% and 8% of boron compound concentrations and was applied to the wood of three Eucalyptus clones. To analyze the equilibrium moisture content, the test samples were acclimatized at different temperatures and relative humidity. The dry density, shrinkage, and anisotropy coefficient for all the wood samples were measured. The presence of the boron compound in impregnated wood enhanced the dry density and radial shrinkage in one of the Eucalyptus clones. The equilibrium moisture content dropped when the 4% boron compound concentration was used to impregnate the wood. The Simpson’s equation must be applied with caution for ascertaining the equilibrium moisture content measurements because different values are achieved when compared with the findings of the acclimatized chambers. |

A impregnação consistiu da aplicação de soluções de 4 e 8% de concentração de compostos de boro na madeira de três clones de eucalipto. Para analisar o conteúdo de umidade de equilíbrio da madeira, as amostras foram aclimatadas em diferentes temperaturas e umidades relativas. A densidade anidra, contração e coeficiente de anisotropia para todas as amostras de madeira foram determinados. A presença de composto de boro na madeira impregnada incrementou a densidade anidra e o inchamento radial para todos os clones de eucalipto testados. O teor de umidade de equilíbrio diminuiu quando a concentração de 4% de compostos de boro foi usada. A equação de Simpson deve ser aplicada com cautela para verificar as medições de conteúdo de umidade de equilíbrio, uma vez que valores diferentes são obtidos quando comparados aos da câmara climatizada.engUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASScientia ForestalisEucaliptoMadeira - QuímicaMadeira - Efeito da umidadeMadeira - DensidadeÁcido bóricoWood impregnationBoric acidEquilibrium moisture contentDensityShrinkageInfluence of the impregnation with boron compounds on the physical properties of Eucalyptus woodInfluência da impregnação com compostos de boro nas propriedades físicas da madeira de eucaliptoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.ipef.br/publicacoes/scientia/nr128/2318-1222-scifor-48-128-e3383.pdfEdy Eime Pereira BaraúnaJuarez Benigno PaesThiago Campos MonteiroJordão Cabral MoulinGabriella Leite FerreiraAmanda Grassmann da SilveiraTalita BaldinCarlos Roberto Sette JuniorMarina Donária Chaves Arantesinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/46036/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALInfluence of the impregnation with boron compounds on the physical properties of Eucalyptus wood.pdfInfluence of the impregnation with boron compounds on the physical properties of Eucalyptus wood.pdfapplication/pdf430436https://repositorio.ufmg.br/bitstream/1843/46036/2/Influence%20of%20the%20impregnation%20with%20boron%20compounds%20on%20the%20physical%20properties%20of%20Eucalyptus%20wood.pdf89802eaf1832274bd05ea4e3d74c5dacMD521843/460362022-10-06 12:13:30.25oai:repositorio.ufmg.br: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Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2022-10-06T15:13:30Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |
