Mechanical and physical properties of particleboard from plywood edge trimming / Nor Ayu Amira Abdull Wahab

This study investigates the potential of edge trimming waste as a raw
material for manufacturing particleboard. The edge trimming were recycle
wood and this wood used to manufacture panel for three different resin
content (8, 10, 12%) and two density (600, 700 kg/m3). The influences of
resin content and density on mechanical and physical properties of
particleboard manufactured were determined. The experimental panels were
tested for their mechanical strength including modulus of rupture (MOR),
modulus of elasticity (MOE), internal bonding (IB) and physical properties
which is thickness swelling (TS) and water absorption (WA) were
determine based on British European (BS EN) standard. For the result of
mechanical properties, the MOR and MOE did not satisfy the minimum of
MOR and MOE standard. Range of MOR for particleboard is 2.96 to 7.99
MPa and it not satisfied the minimum standard which is 15 MPa and range
for MOE is 689 to 1675 MPa and it also not satisfied the minimum standard
which is 2050 MPa. While for IB, it is achieve the requirement of standard
which is 0.45 MPa. For the physical properties, the TS did not satisfy the
maximum requirement of standard which is 14%. Range for TS is 64.58 to
37.80% and it not achieves the maximum standard. Mechanical and
physical properties strength of particleboard were increased toward density
of board and resin contents used were increased.
