Resumo: | The objective of this study was to evaluate the physical properties of high density particleboard (HDP) produced with pine, bamboo and co-participation of yerba mate, by means of mixtures modeling. Particles of bamboo (Phyllosttachys aurea), finely chopped sticks of yerba mate (Ilex paraguariensis) and Pinus taeda wood were used. These particles, in different proportions of mixtures, were glued in a drum-type rotary mixer with Melamine-Urea-Formaldehyde (MUF) resin, handmade molded and pressed in hydraulic press at 120 °C and 60 kgf.cm-2 for 10 minutes, up to the thickness of the 6 mm. The panels were produced with 0.90 g.cm-³ of nominal density and, after pressing, were stabilized in an air-conditioned environment at 20º C and 65% of the relative humidity. Statistical analysis follows simplex centroid planning, with seven combinations of the three components and three replicates. It was found that the apparently density, moisture content, thickness swelling (2 and 24 hours water immersion), water absorption (2 hours), are explained by the cubic model, while the water absorption (24 hours) are explained by the quadratic model. The materials used made it possible to produce high density particleboard (HDP) with physical properties that varied according to the different mixtures, however, the best results were observed for the panels produced with bamboo and Pinus taeda. |

Se utilizaron partículas de bambú (Phyllosttachys aurea), finos palos de yerba mate (Ilex paraguariensis) y madera de Pinus taeda. Estos materiales, en diferentes proporciones de mezclas, se pegaron al mezclador de tambor giratorio, con resina de Melamina-Urea-Formaldehído (MUF), prefabricados y prensados en una prensa hidráulica a 120 °C, durante 10 minutos, con 60 kgf.cm-2 de presión, en el espesor de 6 mm. Los paneles se produjeron con 0,90 g.cm-³ de densidad nominal y, después del prensado, se estabilizaron en un ambiente con aire acondicionado a 20 ° C y 65% de humedad relativa. Se realizó un análisis estadístico o plan central simplex, con siete combinaciones de tres componentes y tres repeticiones. Se encontró que la densidad aparente, el contenido de humedad, el aumento de espesor (2 y 24 horas de inmersión en agua) y la absorción de agua (2 horas) se explicaron por el modelo cúbico, mientras que la absorción de agua (24 horas) fue explicado por el modelo cuadrático. Los materiales utilizados permitieron producir paneles de partículas de alta densidad (HDP), con propiedades físicas que variaron según las diferentes mezclas, sin embargo, los mejores resultados se observaron en los paneles producidos con las mezclas de bambú y Pinus taeda.O objetivo deste estudo foi avaliar as propriedades físicas de painéis de alta densidade (HDP) produzidos com pinus, bambu e coparticipação de erva-mate, por meio do método de modelagem de misturas. Foram utilizadas partículas de bambu (Phyllosttachys aurea), de palitos finos de erva-mate (Ilex paraguariensis) e da madeira de Pinus taeda. Estes materiais, em diferentes proporções de misturas, foram encolados em misturador rotativo tipo tambor, com a resina Melamina-Ureia-Formaldeído (MUF), pré-moldadas a mão e prensadas em prensa hidráulica a 120oC, por 10 minutos, com 60 kgf.cm-2 de pressão, até a espessura de 6 mm. Os painéis foram produzidos com 0,90 g.cm-³ de densidade nominal e, após a prensagem, foram estabilizados em ambiente climatizado à 20º C e 65% de umidade relativa. A análise estatística seguiu o planejamento centróide simplex, com sete combinações dos três componentes e três repetições. Verificou-se que a densidade aparente, o teor de umidade, o inchamento em espessura (2 e 24 horas de imersão em água) e absorção de água (2 horas) foram explicadas pelo modelo cúbico, enquanto a absorção de água (24 horas) foi explicada pelo modelo quadrático. Os materiais utilizados possibilitaram a produção de painéis particulados de alta densidade (HDP), com propriedades físicas que variaram em função das diferentes misturas, contudo, os melhores resultados foram observados nos painéis produzidos com as misturas de bambu e Pinus taeda.Research, Society and Development2020-05-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/402210.33448/rsd-v9i7.4022Research, Society and Development; Vol. 9 No. 7; e436974022Research, Society and Development; Vol. 9 Núm. 7; e436974022Research, Society and Development; v. 9 n. 7; e4369740222525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/4022/3586Copyright (c) 2020 Fernando Rusch, Erick Chagas Mustefaga, Evandro Teleginski, Rômulo Trevisan, Éverton Hilliginfo:eu-repo/semantics/openAccessRusch, FernandoMustefaga, Erick ChagasHillig, ÉvertonTrevisan, RômuloTeleginski, Evandro2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/4022Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:01.149567Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
