Abstract

The genus Sida may become a promising alternative source for the production of particleboards. Nowadays it is used for manufacturing ropes due to the quality of its fibers, however, there is no research relating the production of particleboards using this lignocelluloses material. This study aimed to evaluate the effect of eucalyptus (Eucalyptus urophylla), paricá (Schizolobium amazonicum) and vassoura (Sida spp.) on the physical and mechanical properties of particleboard. Particleboard contained 25, 50, 75 and 100% of eucalyptus and paricá or eucalytus and vassoura or paricá an vassoura were fabricated. Two (6% and 8%) amounts of urea-formaldehyde adhesive were used. The physical and mechanical properties were determined according to NBR / ABNT 14810- 3 (ASSOCIAÇÃO BRASILEIRA DE NORMAS TÉCNICAS - ABNT, 2002). It was observed that increase in resin content in the improved some physical and mechanical properties. It was concluded that the amount of vassoura particles on panels had different effects depending on the species used. The increase in the percentage of vassoura particles in the Eucalyptus panels did not affect the internal bond, screw withdrawal and hardness. Increasing the percentage of vassoura particles on the panels produced with paricá did not affect its hardness and resistance to screw withdrawal. The panels produced with vassoura particle absorbed more water and, consequently, increased the thickness swelling, and therefore is not recommended for use in environments with high humidity. It was concluded that the genus Sida, in general, has potential for particleboard production.
