Abstract
This study was conducted to examine the effects of particle pre-treatment on
the properties of particleboard made from oil palm trunk particles by evaluating the
physical, mechanical and biological durability properties. A total of nine types oil
palm trunk particleboards were manufactured from different particles treatment
(untreated, hot water and NaOH) with different preservative addition (0.06% and
0.1%) at a target density of 0.65 g/cm3, pressed at 150°C for 10 minutes. Urea
formaldehyde (UF) was used as the binder. Bending strength, internal bonding (IB)
strength, thickness swelling, water absorption, fungal decay, termite decay and soil
burial of the particleboards were analyzed. Fourier Transform Infrared (FT-IR)
spectroscopy was used to detect the presence of functional groups that exists in the
manufactured particleboards. The decomposition and thermal performance of the
boards were evaluated by Thermogravimetric Analysis (TGA). Scanning Electron
Microscopy (SEM) was employed to view the structural changes of manufactured
boards before and after treatments. Based on the outcome in this study,
particleboards made from particles treated with hot water have the higher modulus of
elasticity (MOE), modulus of rupture (MOR), and IB strength compared to
particleboards made from untreated particles. The addition of preservative in the urea
formaldehyde increased the durability of the boards with the reduction of weight loss
in fungal decay, termite decay and soil burial. According to British standard BS EN
319 (1993), all the evaluated boards mostly fulfilled the requirement of IB strength
for particleboard type P2, P3, P4 and P5 respectively excluding boards made from
particles treated with sodium hydroxide (NaOH). However, all boards did not meet
the satisfactory standards for thickness swelling (TS) and water absorption (WA). Based on this study, it showed that further research is required to improve and
enhance the physical properties of oil palm trunk particleboards with various
treatments.
