Resumo: This work aimed to evaluate the physical and mechanical properties of particleboard panels manufactured with wood particles from Sequoia sempervirens and Pinus taeda and urea-formaldehyde resin (UF), using different mixing ratios of the two species, namely 100%, 0%, 75%, 50% and 25% of sequoia particles. Properties evaluated included panel density and compaction ratio, water absorption and thickness swelling after 24 hours of immersion, internal bond and static bending (MOE and MOR). The low density of sequoia wood raised the compaction ratio of the panels and helped improve their mechanical properties and dimensional stability. Panels manufactured at the ratios of 100%, 75%, 50% and 25% sequoia to pine provided better results compared to panels manufactured with 100% pine. Results of MOE and MOR under static bending and of internal bond met the minimum requirements of standard EN 312:2003 in all treatments. Results revealed that Sequoia sempervirens has great potential for production of particleboard.

Foram avaliadas as propriedades de massa específica e razão de compactação dos painéis, absorção de água e inchamento em espessura após 24 horas de imersão, ligação interna e flexão estática (MOE e MOR). A baixa massa específica da madeira de sequoia elevou a razão de compactação dos painéis e contribuiu para melhorar as suas propriedades mecânicas e estabilidade dimensional. Os painéis produzidos com sequoia nas proporções de 100%, 75%, 50% e 25% em mistura com pinus, apresentaram melhores resultados de propriedades em relação aos painéis produzidos com 100% de pinus. Os resultados de MOE e MOR em flexão estática e ligação interna de todos os tratamentos avaliados atenderam aos requisitos mínimos da norma EN 312:2003. Os resultados demonstram que a Sequoia sempervirens apresenta grande potencial para produção de painéis aglomerados.Universidade Federal de Lavras (UFLA)2016-04-062017-08-01T20:13:49Z2017-08-01T20:13:49Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfIWAKIRI, S. et al.
