Abstract :

This study conducted to investigate usability of soya stalk as lignocellulosic material and wood alternative in particleboard manufacturing. Four levels of soya stalk (25, 50, 75, and 100%), 3 level of press time (5, 6, and 7 min), and the content of resin in 3 levels (8, 10, and 12%) were considered as dependent variables. Results showed that bending properties (MOR and MOE) were enhanced by increasing soya stalk content in boards, while internal bonding (IB) property decreased. However, water uptake and thickness swelling after 2 and 24 immersions were increased. With increasing in resin content and press time, both mechanical and physical properties including bonding properties, internal bonding properties, water uptake and thickness swelling were suppressed. The results showed that soya stalk is a suitable wood alternative in particleboard manufacturing.
