Resumo: | This work aimed at evaluating the quality of particleboard manufactured with different wood proportions (Eucalyptus grandis) and rice husk. The composites were produced in the proportions 0, 20, 40, 60, 80, and 100% of rice husk with the use of urea-formaldehyde and tannin-formaldehyde adhesives. In order to characterize the quality of the particleboards, physical properties (density; moisture content; water absorption and thickness swelling after 2 and 24 hours of immersion in water) and mechanical properties (static bending; internal bonding and screw withdrawal) were considered. Results showed that increasing rice husk proportion caused larger instability and a decrease in the resistance of particleboards. Particleboards manufactured with tannin-formaldehyde resins presented higher quality when compared to urea-formaldehyde. |

No presente trabalho, avaliaram-se as propriedades físico-mecânicas de painéis aglomerados produzidos com diferentes proporções de madeira (Eucalyptus grandis) e casca de arroz. Para caracterização dos painéis produzidos com os adesivos ureia-formaldeído e tanino-formaldeído, nas proporções 0, 20, 40, 60, 80 e 100% de casca de arroz, determinaram-se as propriedades físicas (massa específica; teor de umidade; absorção de água e inchamento em espessura após 2 e 24 horas de imersão em água), e de resistência mecânica (flexão estática; ligação interna e arrancamento de parafusos). Os resultados obtidos indicaram que o acréscimo da casca de arroz proporcionou uma maior instabilidade e uma menor resistência das chapas. Quando confeccionados utilizando a resina à base de tanino, os painéis apresentaram qualidade superior.Universidade Federal de Santa Maria2009-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/89910.5902/19805098899Ciência Florestal; Vol. 19 No. 4 (2009); 449-460Ciência Florestal; v. 19 n. 4 (2009); 449-4601980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/899/627Melo, Rafael Rodolfo deSantini, Elio JoséHaselein, Clovis RobertoStangerlin, Diego Martinsinfo:eu-repo/semantics/openAccess2017-05-08T13:14:52Zoai:ojs.pkp.sfu.ca:article/899Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-08T13:14:52Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
