Effect of Wood Shaving to Improve the Properties of Particleboard Made from Sorghum Bagasse

摘要

The objective of this research was to evaluate the effect of wood shaving added to improve the mechanical properties of particleboard. Wood types were using in this research included of Meranti, Cempedak, Mahagony, and Durian wood. Ratio of Sorghum bagasse and wood shaving was 50/50 (%w/w). Amount of 10% urea formaldehyde (UF) resin used for binding in the manufacturing process. Furthermore, hot pressing of mat at 130°C temperature for 10 minute and 30 kg cm-2 pressure. The final step was conditioning process for 7 days at room temperature before testing of sample. The results showed that the thickness swelling (TS) parameter did not met of JIS A 5908 (2003). Overall the present of wood shaving resulted in decreasing of TS value. Combination of Cempedak and Mahagony wood resulted of the lower TS value compared with control and other treatment. For bending properties, combination of sorghum bagasse and Cempedak wood shaving resulted the best of bending properties. However for the MOE parameter had not met JIS A 5908 (2003). The internal bond (IB) parameter showed that the utilization of wood shaving to produce of particleboard caused of increasing the IB value. The IB value was resulting from this research had met of JIS A 5908 (2003).
