Resumo: | The demand for wood-based products is growing, mainly from planted forests. In this way it is possible to maximize the use of wood and obtain products with resistance and reliability of use. The objective was to study the technological properties of plywood and Laminated Veneer Lumber (LVL) produced with paricá wood (Schizolobium amazonicum Huber ex Ducke). Water absorption, density (basic and apparent), humidity, porosity, thickness swelling and residual swelling were evaluated. 30 specimens of each type of panel were used, the data were analyzed using descriptive statistics and Pearson's correlation matrix. In the plywood, the basic density, bulk density and porosity were 0.38 g cm-3, 0.44 g cm-3 and 75.47%, respectively. Still, the humidity rose 20.91% between 2 and 96 hours of immersion in water. The residual swelling was 3.75% and the thickness swelling increased by 0.81% between 2 and 96 hours of immersion. In LVL, the basic density (0.41 g cm-3) and the apparent density (0.48 g cm-3) were higher in relation to the plywood and the porosity was lower. The residual swelling (4.24%) and the increase in thickness swelling (1.22%) were higher than the plywood. Due to their high hygroscopicity, the applications of the panels evaluated should preferably be in environments without contact with humidity. |

De esta manera, es posible maximizar el uso de la madera y obtener productos con resistencia y fiabilidad de uso. El objetivo fue estudiar las propiedades tecnológicas de la madera contrachapada y LVL (Laminated Veneer Lumber) producida con madera de paricá (Schizolobium amazonicum Huber ex Ducke). Se evaluaron la absorción de agua, la densidad (básica y aparente), la humedad, la porosidad, el hinchamiento del espesor y el hinchamiento residual. Se utilizaron 30 muestras de cada tipo de panel, los datos se analizaron mediante estadísticas descriptivas y la matriz de correlación de Pearson. En la madera contrachapada, la densidad básica, la densidad aparente y la porosidad fueron 0.38 g cm-3, 0.44 g cm-3 y 75.47%, respectivamente. Aún así, la humedad aumentó 20.91% entre 2 y 96 horas de inmersión en agua. La hinchazón residual fue del 3,75% y la hinchazón del espesor aumentó en un 0,81% entre 2 y 96 horas de inmersión. En LVL, la densidad básica (0,41 g cm-3) y la densidad aparente (0,48 g cm-3) fueron mayores en relación con la madera contrachapada y la porosidad fue menor. La hinchazón residual (4,24%) y el aumento de la hinchazón de espesor (1,22%) fueron mayores que la madera contrachapada. Debido a su alta higroscopicidad, las aplicaciones de los paneles evaluados deben realizarse preferiblemente en entornos sin contacto con la humedad.A demanda por produtos a base de madeira é crescente, principalmente a partir de florestas plantadas. Dessa forma é possível maximizar o aproveitamento da madeira e obter produtos com resistência e confiabilidade de utilização. Objetivou-se estudar as propriedades tecnológicas d compensado e do LVL (Laminated Veneer Lumber) produzidos com madeira de paricá (Schizolobium amazonicum Huber ex Ducke). Avaliou-se a absorção de água, densidade (básica e aparente), umidade, porosidade, inchamento em espessura e inchamento residual. Utilizou-se 30 corpos de prova de cada tipo de painel, os dados foram analisados por meio de estatística descritiva e pela matriz de correlação de Pearson. No compensado a densidade básica, densidade aparente e porosidade foram de 0,38 g cm-3, 0,44 g cm-3 e 75,47%, respetivamente. Ainda, a umidade elevou-se 20,91% entre 2 e 96 horas de imersão em água. O inchamento residual foi de 3,75% e o inchamento em espessura aumentou 0,81% entre 2 e 96 horas de imersão. No LVL, a densidade básica (0,41 g cm-3) e a densidade aparente (0,48 g cm-3) foram maiores em relação ao compensado e a porosidade foi menor. O inchamento residual (4,24%) e o aumento em inchamento em espessura (1,22%) foram maiores em relação ao compensado. Por apresentarem alta higroscopicidade, as aplicações dos painéis avaliados devem ser preferencialmente em ambientes sem contato com umidade.Research, Society and Development2020-07-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/608910.33448/rsd-v9i8.6089Research, Society and Development; Vol. 9 No. 8; e786986089Research, Society and Development; Vol. 9 Núm. 8; e786986089Research, Society and Development; v. 9 n. 8; e7869860892525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/6089/5230Copyright (c) 2020 Alessandra Alves Costa, Adriano Reis Prazeres Mascarenhas, Cássio Marques Moquedace dos Santos, Caík Elísio Tonelli Faria, Paulo Junio Duarte, Thiago Moreira Cruzhttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCosta, Alessandra AlvesMascarenhas, Adriano Reis PrazeresSantos, Cássio Marques Moquedace dosFaria, Caík Elísio TonelliDuarte, Paulo JunioCruz, Thiago Moreira2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/6089Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:21.562187Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
