Resumo: The characteristics of cement bonded particleboards can be jeopardized by chemical incompatibility between some lignocellulosic materials and cement, which can inhibit the glue of this cement; however, this effect can be minimized with chemicals treatments of the materials. The different species of Eucalyptus can be promising as raw material in the production of these panels, mainly residues produced in form of barks. The objective of the work was to evaluate chemical compatibility of wood and barks (without and with chemical treatment) of Eucalyptus grandis with cement. The chemical treatment of barks was carried out with sodium hydroxide. Results showed that the Eucalyptus grandis wood presented a moderate aptitude with cement, the treated barks presented high aptitude and the untreated bark presented extremely low aptitude. It was verified positive influence of the chemical treatment in the barks, making possible, in the future, the incorporation of these elements in the manufacturing of cement-bonded particleboard.

Porém, este efeito pode ser minimizado com tratamentos químicos dos materiais. As diferentes espécies de Eucalyptus podem ser promissoras como matéria-prima na produção desse tipo de painel, principalmente os resíduos gerados na forma de cascas. O objetivo deste trabalho foi avaliar a compatibilidade química da madeira e cascas tratadas e não-tratadas quimicamente de Eucalyptus com o cimento Portland. O tratamento químico das cascas foi realizado com solução de hidróxido de sódio. Os resultados obtidos mostraram que a madeira de Eucalyptus grandis apresentou uma aptidão moderada ao cimento, as cascas tratadas, alta aptidão e as cascas não-tratadas, aptidão extremamente baixa. Verificou-se a influência positiva do tratamento químico nas cascas, possibilitando futuramente sua incorporação na manufatura de painéis cimento-madeira.Universidade Federal de Santa Maria2007-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/195710.5902/198050981957Ciência Florestal; Vol. 17 No. 3 (2007); 257-264Ciência Florestal; v. 17 n. 3 (2007); 257-2641980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1957/1211Mori, Fábio AkiraLopes, Yústane Lerissa VeigaMendes, Lourival MarinLatorraca, João Vicente de Figueiredoinfo:eu-repo/semantics/openAccess2017-05-12T14:09:41Zoai:ojs.pkp.sfu.ca:article/1957Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-12T14:09:41Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
