1. PROPRIEDADES FÍSICO-MECÂNICAS E RESISTÊNCIA A BIODETERIORADORES DE CHAPAS AGLOMERADAS CONSTITUÍDAS POR DIFERENTES PROPORÇÕES DE MADEIRA E CASCA DE ARROZ / PHYSICAL-MECHANICAL PROPERTIES AND DECAY RESISTANCE OF WOOD AND RICE HUSK PARTICLEBOARD IN DIFFERENT PROPORTIONS
This work aimed at evaluating the quality of particleboards manufactured with different wood proportions (Eucalyptus grandis W. Hill. ex Maiden) and rice husk. The composites were produced in the proportions 0, 20, 40, 60, 80 and 100% of peels of rice with the use of urea-formaldehyde and tannin-formaldehyde adhesives. In order to characterize the quality of
