Aproveitamento de resíduo de madeira de Hymenaea courbaril para produção de painéis aglomerados convencionais em comparação com painéis de Pinus oocarpa

Abstract

The accumulation of sawmill waste, mainly sawdust can compromise the environment causing impacts with damages of difficult repair, needing to be properly managed. The objective of this work was to evaluate the technical potential of using sawmills from Hymenaea courbaril for the production of conventional agglomerated panels, comparing with panels of Pinus oocarpa. Three panels were produced per treatment, being that they had dimensions of 20.0 x 20.0 x 1.5cm and nominal density of 0.60 g / cm³. Urea-formaldehyde adhesive was applied at a ratio of 9% based on its solids content. The press cycle used was of temperature of 160ºC, pressure of 4,0MPa and time of 15 minutes. Based on the results it can be verified that the jatobá residue meets all the regulations, having the technical potential to be used in the production of particleboard.
