Abstract:
The recycling of forest residues was investigated in the present study. It arms to determine the physical and mechanical properties of particleboards from mahogany sawdust bonded by pearls bone glue or tannic powder of peel of Indian tamarind (Pithecellobium Dulce). The influence of the size of particles on the physical and mechanical properties of the particleboards is studied. Five different granulometries (raw sawdust; 2.5 < g £ 5; 1.6 < g £ 2.5 and 0.8 < g £ 1.6, and g £ 0.8) were investigated. The rate of the adhesives used were 5; 6.5; 7; 7.5; 8; 10, 12.5 and 15 percent. Physically, the density, thickness swelling (TS) and water absorption (WA) were evaluated. Mechanically, the modulus of elasticity (MOE), the modulus of rupture (MOR), the modulus of Young E, the tensile modulus of rupture (MOT) and the internal bond (IB) were determined. The results obtained showed that the granulometry has a great influence on the physical as well as the mechanical properties of the Mahogany sawdust particleboards. The pressing temperature is 160 °C. The threshold fixed by the American standard ANSI A208.1-2016 for the MOE and the MOR are widely reached. The values of the density classified the particleboards from sawdust of Mahogany wood in the categories of low and mean density. The thickness swelling and water absorption has not respectful to the American standard ANSI A208.1–2016 [1]. So, the manufactured boards can only be used in dry conditions.
