This study examined the effects of some pre-treatments on some physical and mechanical properties of particleboard manufactured from vine pruning. Chips that were produced from vine pruning were subjected to some pre-treatments namely cold water, 1 % sodium hydroxide, and 1 % acetic acid in order to improve their performance in particleboard manufacturing. One-layer experimental particleboards with density of 0.5 g/cm3 were manufactured from vine pruning using 6,8,10 % percent of urea formaldehyde (UF) adhesive. Modulus of elasticity (MOE), modulus of rupture (MOR), internal bond strength (IB), thickness swelling (TS) and water absorption properties of the boards were evaluated, and a statistical analysis was performed in order to evaluate effects of pre-treatments on physical and mechanical properties. The results have shown that pre-treatments increase bending and internal bond strength of the boards while no significant effects has been observed on modulus of elasticity. The results also indicate that pre-treatments have significant effects on water absorption values of the boards but not on thickness swelling of the boards. This study demonstrates that vine pruning can be more efficiently used in particleboard manufacturing.
