Desempenho De Painéis Osb Com Adesivos Comerciais E Tânico Debarbatimão1

Abstract: RESUMO -O objetivo deste trabalho foi avaliar as propriedades físicas e mecânicas de painéis OSB produzidos com adesivos comerciais e tânico de Stryphnodendron adstringens (Mart.) Coville. Os adesivos comerciais ureia formaldeído (UF), fenol formaldeído (FF) e os taninos da Acacia mearnsi foram obtidos por doação por respectivas empresas produtoras, enquanto que o tanino de barbatimão foi obtido em laboratório. Todos adesivos tiveram as propriedades dos adesivos determinadas. Foram produzidos painéis OSB com o… Show more

“…It is apparently observed a higher compaction of the particles of the reference panel, which was already expected due to the high density of macauba endocarp. This results in a lower compaction ratio and, therefore, in a smaller contact surface between the particles, causing a drop in the transmission of stresses between them and thus, a low performance of the panels in static bending properties (Carvalho et al, 2015). Furthermore, it is noted that the particles were efficiently enveloped by the adhesive, and in Figure 10a there is a distribution in thinner and more homogeneous layers, due to the higher concentration of particles.…”
