- Analysis of glue line and correlations between density and anatomical characteristics of Eucalyptus grandis × Eucalyptus urophylla glulam Rafael G. E. de Oliveira Fabricio G.

Brito Agrociencias resorcinol delamination formaldehyde laminated wood Apparent density This study aimed to analyze the glue line thickness effect and its relation with the density and anatomical characteristics of eucalyptus wood. Thus, the thickness of main and secondary glue lines was measured as well as their interaction with the apparent density of elements glued with resorcinol-formaldehyde (RF) and castor oil polyurethane (CP) adhesives. Anatomical wood characterization of Eucalyptus grandis × Eucalyptus urophylla was performed by correlating glue line thickness. According to normative instruction, specimens were produced for delamination tests. The experiment was conducted in a completely random 2 × 2 design factorial scheme (two classes of wood apparent density and two adhesives). Pearson correlation (t < 0,01) was performed among variables. It was found that there was adhesive penetration into vessels and rays of wood. Glue line thickness was higher in woods with density higher than to 580 kg/m3 glued with RF adhesive. There was a low correlation between wood density and vessel diameter to main and secondary glue lines (t < 0,01). 2020 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48565177008 https://www.redalyc.org/journal/485/48565177008/ https://www.redalyc.org/journal/485/48565177008/html/ https://www.redalyc.org/journal/485/48565177008/48565177008.epub https://www.redalyc.org/journal/485/48565177008/movil en http://www.redalyc.org/revista.oa?id=485 Maderas.
