UTILIZATION OF SAWMILL RESIDUES IN PARTICLEBORD PRODUCTION OF Eucalyptus saligna, Eucaliptus citriodora and Eucalyptus pilularis

ABSTRACT

In this experiment, particleboards of Eucalyptus saligna, E. citriodora and E. pilularis, and a mixtures of this wood species were manufactured in the laboratory. The particles were generated from the slabs deriving from sawmills. Resin levels of 8 and 12% were used. The following board properties were evaluated: water absorption and thickness sweelling after 2 and 24 hours water soaking, modulus of elasticity and rupture in stactic bending tests and internal bonding. The boards showed a high dimensional stability and the properties of the modulus of rupture and internal bonding were higher than the minimum required by the CS 236-66 standard. Based on the results of this research, the uses of these eucaliptus species could be recommended for particleboard production.
