Resumo: The objective of this work was to investigate the strength of particleboards made with wood of Pinus taeda, Eucalyptus saligna, Mimosa scabrella and Hovenia dulcis and mixtures in different proportions and two board compositions. The boards were produced in mixtures of two, three and four species for monolayer boards and proportions of the two species for multilayer boards. Panels were also produced with pure pine wood. The adhesive used was based on urea-formaldehyde and the nominal density was 0.65 g/cm³. We evaluated the properties of density, moisture content, static bending, internal bond and screw withdrawal. The analyzes allowed to evaluating the use of different species wood mixtures in particleboards. The results were also compared the requirements of applicable ANSI A 208.1. The values of static bending, internal bond and screw withdrawal increased with increasing proportion of Pinus taeda and Hovenia dulcis and decreased with increasing proportion of Mimosa scabrella and Eucalyptus saligna. Therefore, it can be concluded that better species were the Pinus taeda and Hovenia dulcis. Regarding the composition, multilayer boards, mostly showed themselves superior to monolayer boards.

Os painéis foram produzidos em misturas de duas, de três e das quatro espécies para painéis monocamada, e nas proporções de duas espécies para painéis multicamadas. Foram também produzidos painéis com madeira de pinus pura. O adesivo usado foi à base de ureia-formaldeído e a massa específica nominal estabelecida foi de 0,65 g/cm³. Foram avaliadas as propriedades físico-mecânicas de massa específica, teor de umidade, flexão estática, ligação interna e arrancamento de parafusos. As análises permitiram avaliar o efeito da utilização da madeira das diferentes espécies em misturas na fabricação dos painéis aglomerados. Os resultados foram também comparados aos requisitos das normas ANSI A 208.1. Verificaram-se aumentos nos valores das propriedades de flexão estática, ligação interna e arrancamento de parafusos com o aumento da proporção de pinus e uva-do-japão e diminuição com aumento da proporção de bracatinga e eucalipto. Portanto, pode-se concluir que as espécies que mais se destacaram foram o pinus e a uva-do-japão. Em relação à composição, os painéis multicamadas, em sua maioria, apresentaram-se superiores aos painéis monocamada.Universidade Federal de Santa Maria2016-06-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2275610.5902/1980509822756Ciência Florestal; Vol. 26 No. 2 (2016); 559-569Ciência Florestal; v. 26 n. 2 (2016); 559-5691980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/22756/pdfCopyright (c) 2016 Ciência Florestalinfo:eu-repo/semantics/openAccessSanches, Felipe LuisHillig, ÉvertonIwakiri, SetsuoNapoli, Lygia Maria2017-04-06T18:26:54Zoai:ojs.pkp.sfu.ca:article/22756Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-06T18:26:54Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
