Resumo
O presente trabalho tem por objetivo o reaproveitamento de resíduos sólidos na preparação de painéis para uso na arquitetura. Para atingir as metas propostas, painéis foram preparados a partir de resíduos provenientes de embalagens cartonadas e plásticas, utilizando-se como elemento de reforço, resíduos lignocelulósicos (casca de amendoim e de arroz). A concentração e a natureza dos resíduos utilizados como matriz e como carga foram variadas gerando doze condições experimentais diferentes. As propriedades avaliadas dos painéis foram o módulo de ruptura, módulo de elasticidade, tração perpendicular à superfície, inchamento em espessura, absorção de água e densidade. Todos os ensaios foram realizados segundo as normas ASTM D1037 e EN 317, referente à chapa de partículas. Os resultados foram analisados segundo a norma ANSI A208.1 que especifica as propriedades de desempenho requeridas para as chapas de partículas. Os painéis foram classificados como de baixa densidade, podendo ser utilizados como forros, divisórias, revestimento decorativos e demais aplicações que requerem as mesmas propriedades físicas e mecânicas. Os painéis a base de embalagem plástica reforçados com casca de arroz apresentaram propriedades superiores do que os demais painéis produzidos. O elemento arquitetônico desenvolvido neste estudo representa um novo mercado potencial, podendo ser empregado no ambiente urbano e rural, atendendo ao conceito de produto ecoeficiente.
This work aims to evaluate the utilization of solid residues in the preparation of panels for civil construction. Panels were prepared from residues based on multilayer packages and plastics, reinforced with lignocellulosics residues (peanut shells and rice hulls). Several blends were prepared with different ratios of components, resulting in twelve treatments. The following physical and mechanical properties were evaluated: modulus of elasticity, modulus of rupture, perpendicular tension to panel plan, water swelling and absorption. All tests were carried out according to the ASTM D1037 and EN 317 standards concerning particleboard. The results were analyzed considering the ANSI A208.1 standard, which specifies the required properties for particleboards. The treatments using rice hulls as reinforcement load and plastic packaging as matrix presented better performance than the treatment using peanut shells. The panels tested were classified according to ANSI standards as low density panels. The present study shows that this technology is feasible and the results presented lead to a promising use as architectonical element.
