Analysis of physical, chemical e mechanical properties of woodparticle boards containing biaxially oriented polypropylene/Estudo das propriedades fisicas, quimicas e mecanicas de paineis de madeira aglomerada com insercao de residuos contendo polipropileno biorientado

Considering the increased generation of solid waste and the difficulty of proper final disposal, it is of utmost importance to study the reuse of solid waste, seeking a beneficial alternative for the population and the environment. This study aimed to produce wood particle boards incorporated with different percentage of waste from the manufacture of labels and tags, commonly known as paper shavings, containing biaxially oriented polypropylene (BOPP), aiming its reuse. Physical, chemical and mechanical tests were performed. The difference in density between the materials used to manufacture the boards influenced the production process as well as the amount of waste added. Values of moisture content and thickness swelling remained within the range set by the regulations. The results for water absorption analysis are in agreement with those in the literature on the incorporation of different types of waste in the boards. According to our findings, it was observed the importance of a homogeneous mixture of the materials, and pH control. The incorporation of waste containing BOPP into particle boards may be a promising disposal alternative for this waste, given the development of a byproduct that encourages sustainable development. Keywords: incorporation, paper scrap, particle board, analysis. E de grande importancia o estudo do reaproveitamento dos residuos solidos, devido ao aumento de sua geracao e dificuldade de disposicao final adequada, a fim de buscar uma alternativa benefica para a populacao e para o ambiente. O objetivo principal deste trabalho foi a incorporacao de diferentes porcentagens de residuos provenientes da fabricacao de rotulos e etiquetas, conhecidos como aparas, contendo polipropileno biorientado (BOPP) em paineis de madeira aglomerada, visando seu reaproveitamento. Foram realizados testes fisicos, quimicos e mecanicos. Observou-se que a diferenca de densidade entre os materiais influencia no processo de producao dos paineis, assim como a quantidade de residuo adicionada. As analises de teor de umidade e de inchamento em espessura mantiveram-se dentro do estabelecido pelas normativas. Os resultados encontrados para a analise de absorcao de agua estao de acordo com os apresentados em literatura, para incorporacao de diferentes tipos de residuos nos paineis. De acordo com os resultados obtidos pode-se observar a importancia de uma mistura homogenea dos materiais, e o controle do pH. A incorporacao de residuos contendo BOPP em paineis de ma
