Resumo: Medium-density particleboards represent an alternative for the use of lignocellulosic by-products, found in abundance and which causes environmental impacts when improperly disposed of. In this scope, the objective of this research was to evaluate the potential of multilayer particle boards, produced with sugarcane bagasse and polyurethane resin based on castor oil (PU-castor) and compare the results with the requirements established by the Brazilian standard for wood particle board (NBR 14810-2:2018). For that, the physical and mechanical properties and the resistance to humidity of multilayer particle boards with a thickness of 15 mm and medium density (600 and 750 kg.m-3) of agglomerated sugarcane bagasse particles were analyzed. with castor oil PU resin (12% for the inner layer and 15% for the outer layer). The results obtained indicated that the panels with 750 kg.m-3 presented better performance, reaching all the requirements required to classify them, according to the recommendations of the Brazilian standard for wood panels, such as P2 type panels, non-structural use in dry conditions.

Nesse escopo, o objetivo desta pesquisa consistiu em avaliar o potencial de painéis de partículas multicamadas, produzidos com bagaço de cana-de-açúcar e resina poliuretana à base de óleo de mamona (PU-mamona) e confrontar os resultados com os requisitos estabelecidos pela norma brasileira de painéis de partículas de madeira (NBR 14810-2:2018). Para tanto, foram analisadas as propriedades físicas e mecânicas e a resistência à umidade, de painéis de partículas multicamadas com espessura de 15 mm e média densidade (600 e 750 kg.m-3) de partículas de bagaço de cana-de-açúcar aglomeradas com resina PU mamona (12% para camada interna e 15% para camada externa). Os resultados obtidos indicaram que os painéis com 750 kg.m-3 apresentaram melhor desempenho, atingindo todos os requisitos exigidos para classificá-los, de acordo com as recomendações da norma brasileira para painéis de madeira, como painéis do tipo P2, uso não estrutural em condições secas.Universidade Federal de Santa Maria2023-09-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6962410.5902/1980509869624Ciência Florestal; Vol. 33 No. 3 (2023): Publicação Contínua; e69624Ciência Florestal; v. 33 n. 3 (2023): Publicação Contínua; e696241980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/69624/61686Copyright (c) 2023 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessDuran, Afonso José Felício PeresLopes Junior, Wanley EduardoPavesi, MarianaFiorelli, Juliano2023-09-19T21:43:47Zoai:ojs.pkp.sfu.ca:article/69624Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-09-19T21:43:47Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
