Physical and Mechanical Properties of Paricá Wood Species Treated with CCB Preservative

Abstract

This research presents the production and the evaluation of particleboards manufactured with <i>Eucalyptus grandis</i> and oat hulls (<i>Avena sativa</i>), pressure bonded with castor oil based polyurethane resin (PU). Strength and stiffness properties in static bending of the panels were determined based on the standards ABNT NBR 14810:2006 [1], ANSI A208.1: 1999 [2], BS EN 312:2003 [3] and CS 236-66:1968 [4]. Analysis of variance (ANOVA) was used to evaluate the influence of the factors: mass fractions of PU resin (10, 12 and 14%) and the composition in mass fractions of <i>Eucalyptus grandis</i> (100, 85, 70 and 0%) and oat hulls (0, 15, 30 and 100%) in the properties modulus of elasticity (MOE) and modulus of rupture (MOR). Statistical analysis results indicated that <i>Eucalyptus grandis</i> and adhesive were significant in the MOE and MOR properties. However, the interaction <i>Eucalyptus grandis</i>-adhesive did not significantly affect the properties evaluated.
