Experimental particleboard from bagasse and industrial wood particles

ABSTRACT: The aim of this study was to product of three layerexperimental particleboards using mixture of bagasse andindustrial wood particles. The ratio of the mixture of bagasse and wood particles, in the surface and middle layers were 20:80, 30:70 and 40:60, respectively. Press times were selected at two levels of 5 and 7 min. Two levels of urea formaldehyde resin were selected for the surface layers, namely: 9 and 11 percent. Modulus of elasticity (MOE),modulus of rupture (MOR), internal bonding (IB) and thickness swelling (TS) of the panels were determined according to the procedure of DIN 68763 Standard. The results indicate that all mechanical and physical properties of particleboards improved with an upper percentage of bagasse particles added. In this research, the treatment with 40% bagasse, 11% resin in the surface layers and a 7 min press time has resulted in an optimum particleboard product.
