Produção de compensados de Pinus taeda L. E Pinus oocarpa Schiede com diferentes formulações de adesivo uréia formaldeído

Abstract: Este trabalho teve como objetivo avaliar a qualidade de painéis compensados de Pinus taeda e de Pinus oocarpa, com 20 e 24 anos de idade, respectivamente, utilizando três diferentes formulações de adesivo uréia-formaldeído. Foram produzidos 18 painéis, com três repetições por tratamento. As formulações com maior proporção relativa de resina não influenciaram de forma conclusiva as propriedades físico-mecânicas dos painéis.Os painéis de P. oocarpa apresentaram valores médios de resistência da linha de cola, mód… Show more

“…Table 5 presents the results of glue line shear strength assays for plywood panels made with Melia azedarach and Pinus taeda , glued with FF resin. Comparing the results reported in literature, Iwakiri et al (2002), studying plywood panels made with Pinus taeda and glued with FF resin, found that shear stresses values in the boiling cycle test varied from 0.94 to 1.26 MPa. Bortoletto Jr (2003) obtained, for phenolic plywood panels produced from 11 Eucalyptus species, shear stresses values from 1.91 to 2.42 MPa in the boiling cycle test.…”

“…The literature contains several studies on the manufacture of particleboards using particles or fibers from different lignocellulosic sources and synthetic binders or adhesives 7,[13][14][15][16][17][18][19][20] to bond the particles, often by applying heat 21 . Castor oil-based bi-component polyurethane adhesive 22 has been widely used because it is renewable, biodegradable and has a low degree of toxicity [23][24][25] .…”

“…2016 DOI: dx.doi.org/10.18671/scifor.v44n110.22 INTRODUÇÃO A espécie é uma das variáveis de maior importância no processo de confecção de painéis de madeira aglomerada de média densidade (MDP) uma vez que interfere significativamente na qualidade do mesmo. Em geral madeiras de baixa densidade são mais adequadas, pois aumentam a razão de compactação e desse modo concedem melhores características mecânicas aos painéis produzidos (IWAKIRI et al, 2002).…”
