The Study on the Effects of Sodium Silicate on Particleboard Made from Sugarcane Bagasse
Particleboard is an engineered wood product, factory-made from wood particles e.g. sawmill shavings, wood chips and saw dust and they are bonded into a solid board by appropriate binder. The scope of this paper is aimed to study the performance of particleboard made from sugarcane bagasse with the sodium silicate as the binder. The particleboards were produced by hot pressed at 150°C, 170°C and 190°C with the holding times of 20, 25 and 30 minutes respectively, at 10MPa. Different ratios of sodium silicate with reference to the bagasse by weigh i.e. 20%, 15% and 10% were added before the hot press process. The results obtained from the study shown that, the properties of the particleboard produced at the heating temperature of 170°C in 30 minutes with the addition of 20% of sodium silicate was the most promising. The densities, thickness swelling, flexural/bending strength and internal bond of the particleboards were tested based on the Japanese Industrial Standard (JIS), JIS A 5908:2003.
