Resumo: | The objective of this work was to investigate the quality of particleboards made with Eucalyptus saligna wood residues, resulting from the chiping of logs for pulp production. The boards were producted with two types of residues, sticks and sawdust, used pure. The adhesive used was urea-formaldehyde resin in proportions of 4, 8 and 12% (based on ovendry weight of wood particles) and the nominal densities were 0.55, 0.65 and 0.75 g/cm3. Bending properties, internal bond, screw withdrawal, water absorption and thickness swelling ware evaluated. The results indicated that the bending properties, internal bond and screw withdrawal were slightly higher with the sawdust type residue than boards made with sticktype residue. For water absorption, the values increased with the reduction of the density, for both type of particles. Thickness swelling increased with the reduction of resin proportion, independent of the type of residue used. Results showed that using both particles type with larger resin proportion and larger densities, boards with acceptable quality can be made. |

As chapas foram produzidas com dois tipos de resíduos, palitos e serragem, sendo utilizados puros. O adesivo usado foi à base de uréia-formaldeído em proporções de 4; 8 e 12%, com base na massa seca das partículas, e as densidades nominais das chapas foram de 0,55; 0,65 e 0,75 g/cm3. Foram avaliadas propriedades de flexão estática, ligação interna, arrancamento de parafusos, absorção d'água e inchamento em espessura. Os valores obtidos das propriedades de flexão estática, ligação interna e arrancamento de parafusos aumentaram com a densidade da chapa, assim como com o teor de adesivo, independentemente do tipo de resíduo. No caso da absorção d'água, os valores aumentaram com a redução da densidade, tanto para chapas produzidas com partículas tipo palitos como para serragem. Para inchamento em espessura, os valores aumentaram com a diminuição do teor de adesivo, sem considerar o do tipo de resíduo utilizado. Os resultados permitem concluir que, usando-se tanto partículas tipo palitos quanto serragem com maiores percentagens de adesivo e maiores densidades, podem ser produzidas chapas com qualidade satisfatória.Universidade Federal de Santa Maria2006-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/189910.5902/198050981899Ciência Florestal; Vol. 16 No. 2 (2006); 201-212Ciência Florestal; v. 16 n. 2 (2006); 201-2121980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1899/1145Pedrazzi, CristianeHaselein, Clovis RobertoSantini, Elio JoséSchneider, Paulo Renatoinfo:eu-repo/semantics/openAccess2017-05-15T14:25:20Zoai:ojs.pkp.sfu.ca:article/1899Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-15T14:25:20Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
