Avalia？？o do potencial de utiliza？？o da madeira de Schizolobium amazonicum "Paricá" e Cecropia hololeuca "Embaúba" para produ？？o de painéis aglomerados

this research was developed to evaluate the potential use of the woods schizolobium amazonicum (paricá) and cecropia hololeuca (embaúba) for manufacturing particleboard. were made panels with the densities of 0.70 g/cm3, using mixtures of urea-formaldehyde resin and wood particles of paricá and embaúba, in proportions of 75, 50 and 25%. the pinus taeda wood was used as the reference. the panels were pressed at the temperature of 160oc, pressure of 40 kgf/cm2, for 8 minutes. the evaluations of the properties of water absorption, thickness swelling, internal bond, modulus of elasticity and modulus of ruptures, showed that the woods of schizolobium amazonicum (paricá) e cecropia hololeuca (embaúba) are technically feasible for particleboard manufacture.
