الوصف: | This work aimed at evaluating the quality of particleboard manufactured with different wood proportions (Eucalyptus grandis) 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. |
