PROPERTIES OF WOOD AND RICE HUSK PARTICLEBOARD IN DIFFERENT PROPORTIONS
<p>This work aimed at evaluating the quality of particleboard manufactured with different wood proportions (<em>Eucalyptus grandis</em>) and rice husk. The composites were produced in the proportions 0, 20, 40, 60, 80, and 100% of rice husk with the use of urea-formaldehyde and tan...

| description | <p>This work aimed at evaluating the quality of particleboard manufactured with different wood proportions (<em>Eucalyptus grandis</em>) and rice husk. The composites were produced in the proportions 0, 20, 40, 60, 80, and 100% of rice husk with the use of urea-formaldehyde and tannin-formaldehyde adhesives. In order to characterize the quality of the particleboards, physical properties (density; moisture content; water absorption and thickness swelling after 2 and 24 hours of immersion in water) and mechanical properties (static bending; internal bonding and screw withdrawal) were considered. Results showed that increasing rice husk proportion caused larger instability and a decrease in the resistance of particleboards. Particleboards manufactured with tannin-formaldehyde resins presented higher quality when compared to urea-formaldehyde.</p><p> </p> |
