The performance of particleboard made from rice husk and coconut husk based on type density and type of raw material / Jonity Philip

The increase in waste production from agricultural waste has contributed to
various environmental problems. In Malaysia, agricultural is the main sector
industry especially for rice and coconut production. Coconut husks and rice
husks, residues generated during the processing, are available in abundant
quantities in many parts of the tropics but are often treated as a waste material.
This study investigated the performance of particleboard made from rice husk
and coconut husk based on type density (500kg/m3
, 600kg/m3
, 700kg/m3
) and
type of raw material (rice husks, coconut husk and mixing). Material type gave
the effect on board properties. For mechanical (MOR and MOE) and physical
properties (TS and WA), there were high significant between material. Material
with fiber structure like coconut husk resulted in higher value of MOR, MOE and
IB compared to rice husk and mixing. Even so, in TS testing, mixing sample
recorded highest value in percentage after coconut husk and rice husk sample.
But in WA, coconut husk samples show more resistant to water compared to
others. Density also gave great impact on properties of particleboards. The
higher density (700kg/m3
) gave more bonding strength in mechanical properties
(MOR, MOE and IB) than lower density (500kg/m3 and 600kg/m3
) and resulted
in more resistant towards water. The developed particle board composites can
be used for general purpose requirement, such as paneling, ceilings or furniture.
