| Summary: | This study investigated the potential of the oil palm particles and oil palm
starch produced and extracted from the oil palm trunk. Commercial rubberwood
particles and wheat starch were used as a comparison. The starches were modified
with polyvinyl alcohol to change its properties for better performance. Basic
properties of raw materials were determined for their final properties of the boards.
The raw materials were also characterized using scanning electron microscopy, xray
diffractometry analysis, thermogravimetric analysis, and differential scanning
calorimetry analysis. Comparisons were made between boards and panels bonded
with urea formaldehyde were used as a control board.
The physical and mechanical testing carried out based on japanese industrial
standard a5908, which include density, moisture content, dimensional stability
testing, and mechanical strength. All mechanical properties met the requirements,
but none of the physical properties met the requirements except for moisture content.
The panels made using the oil palm particles and bonded with the oil palm starch
showed better mechanical properties, but poor dimensional stability compared to
those panels made with the rubberwood particles, and panels bonded with the wheat starch. |
