Resumo: | Plywood is a wood panel that can be used both in the furniture industry and in construction due to its structural use. However, to be used in construction, it needs to be resistant against wood decay agents and water, without compromising its mechanical properties. The heat treatment is an alternative treatment which improves the wood resistance to fungi and improves its dimensional stability. Thus, the objective of this study is to evaluate the influence of the heat treatment with three different temperatures, 160, 180 and 200°C in the wettability of wood veneers and the shear strength in the bond line of the plywood produced with them. To do so, it was carried out the wettability testing using digital goniometer in the treated veneers at three temperatures and for the control specimen. Besides, it was carried out the shear strength in the bond line test, for testing the quality of bonding according to ABNT NBR ISO 12466-1 (2006). Because of the results obtained, it could be seen that the surface of the treated wood became more hydrophobic with increasing temperature, and this also resulted in a decrease in shear strength in the bond line, once the adhesive used (phenol-formaldehyde) is water based, however, the regulatory requirements have been met. |

Entretanto, para ser utilizado na construção civil, o compensado necessita ser resistente aos agentes xilófagos e à umidade, sem comprometer suas propriedades mecânicas. Nesse aspecto, a termorretificação surge como uma alternativa de tratamento, que aumenta a resistência da madeira ao ataque de fungos e a sua estabilidade dimensional. Desse modo, o objetivo deste trabalho foi avaliar o efeito da termorretificação na qualidade de colagem de lâminas de madeira para a produção de compensado. Para isso, foram realizados os testes de molhabilidade utilizando o goniômetro digital, para lâminas tratadas nas três temperaturas e na amostra de controle. Além disso, foi realizado, o ensaio de cisalhamento na linha de cola, para testar a qualidade da colagem segundo a ABNT NBR ISO 12466-1 (2006). Com os resultados obtidos pode-se perceber que a superfície da madeira tratada se tornou mais hidrofóbica com o aumento da temperatura, e isso resultou também na diminuição da resistência ao cisalhamento na linha de cola, pois o adesivo utilizado (fenol-formaldeído) é à base de água, contudo, os requisitos normativos foram atendidos.Universidade Federal de Santa Maria2018-04-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3158510.5902/1980509831585Ciência Florestal; Vol. 28 No. 1 (2018); 274-282Ciência Florestal; v. 28 n. 1 (2018); 274-2821980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/31585/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessFerreira, Bruno SantosCampos, Cristiane Inácio deRangel, Elidiane Cipriano2018-04-23T20:16:51Zoai:ojs.pkp.sfu.ca:article/31585Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-04-23T20:16:51Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
