Abstract
The increase in demand of particleboards for furniture and other applications has prompted a large-scale research into the
suitability of various types of lignocellulosic materials for its manufacture. For the appropriate use of particleboards produced from
such materials their properties need to be established. This study investigated the possible use of four agro-forest residues generated
in Ghana as an alternative raw material for particleboard manufacture using cassava starch and urea formaldehyde as adhesives. The
particle size of the materials ranged from 0.5 mm to 1.5 mm. An industrial pressing machine was used to press 20 mm × 300 mm ×
300 mm homogeneous single layer particleboard at 170 °C for 480 s using compacting pressure of 3.5 MPa at a targeted density of
600 kg/m3 with adhesive content of 12%. Mechanical properties were determined in accordance with ASTM D 1037-06a and ASTM
D 7519-11. The results indicate that the density of the particleboards produced ranged from 421 kg/m3
to 598 kg/m3
. The results
further indicate that the modulus of elasticity, modulus of rapture, internal bond strength and hardness of the particleboards produced
for both cassava starch and urea formaldehyde were adequate. Comparatively, for all the agro-forest materials used for this study, the
mechanical properties of the particleboards produced using urea formaldehyde as adhesive were better than those produced using
cassava starch as adhesive. It could be concluded that the particleboards produced could be used for indoor applications or interior
furnishings, fitments and other furniture under dry conditions. Additionally, it is recommended that studies on the physical properties
of these manufactured particlebards be conducted.
