Resumo: | This work presents a study of the optimization of castor oil polyurethane (PU) resin content for the production of Oriented Strand Boards (OSB) using bamboo (Dendrocalamus asper). For this study, medium-density (650 kg/m3) OSB panels were produced with different resin contents (8%, 10%, 12%, and 15%). The bamboo particles were characterized through physical, chemical and anatomical analyses, identifying the potential of this product as a raw material for OSB panels. Subsequently, the physical and mechanical properties of OSB panels were evaluated. The results indicated that bamboo and castor oil PU are suitable for the production of OSB panels, and all the conditions met the minimum requirements of the European standard EN 300 (2002), for OSB type 1. In particular, the best overall properties were obtained by the panels with a resin content of 12%, achieving the minimum requirements for applications as a structural panel (type 4), opening new opportunities for formaldehyde-free engineered bamboo materials for the built environment. |

Para este estudo, painéis OSB de densidade média (650 kg/m3) foram produzidos com diferentes teores de resina (8%, 10%, 12% e 15%). As partículas de bambu foram caracterizadas através das análises física, química e anatômica, identificando o potencial deste produto como matéria-prima para a produção de painéis OSB. Posteriormente, foram avaliadas as propriedades físicas e mecânicas dos painéis OSB. Os resultados indicaram que o bambu e a resina PU a base de óleo de mamona se mostrou adequado para a produção de painéis OSB e todas as condições atendem aos requisitos mínimos da norma europeia EN 300 (2002), para OSB tipo 1. Em particular, as melhores propriedades em geral foram obtidas pelos painéis com um teor de resina de 12%, atingindo todos os requisitos mínimos para aplicações como um painel estrutural (tipo 4), abrindo novas oportunidades para materiais de bambu projetados sem formaldeído para o ambiente construído.Universidade Federal de Santa Maria2022-03-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontextoinfo:eu-repo/semantics/otherapplication/pdftext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/4690810.5902/1980509846908Ciência Florestal; Vol. 32 No. 1 (2022); 187-205Ciência Florestal; v. 32 n. 1 (2022); 187-2051980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/cienciaflorestal/article/view/46908/46355https://periodicos.ufsm.br/cienciaflorestal/article/view/46908/50571Copyright (c) 2022 Ciência Florestalhttps://creativecommons.org/licenses/by-nc/4.0/info:eu-repo/semantics/openAccessBarbirato, Guilherme Henrique AmentGauss, ChristianLopes Junior, Wanley EduardoMartins, RômuloFiorelli, Juliano2023-03-22T12:39:04Zoai:ojs.pkp.sfu.ca:article/46908Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-03-22T12:39:04Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
