Effect Of Particle Geometry On Properties Of
Binderless Particleboard From Oil Palm (E/Aeis
Guineensis) Trunk.
Masters thesis, Perpustakaan Hamzah Sendut.
Abstract
Binderless particleboard panels were manufactured from two different particle
geometry of oil palm (E/aeis guineensis) trunk. The types of particle used were fine
particles and strands. Strands that were composed of vascular bundles with some
parenchyma cells attached together while fine particles were grounded particles with
size less than I 000 1-1m. The binderless particleboard panel was manufactured with
target density of 0.80 g/cm3 Binderless particleboard panels were tested for their
mechanical and physical properties such as modulus of rupture (MOR) or bending
strength, internal bond strength (IB), thickness swelling (TS), water absorption (W A)
and surface roughness. Chemical analysis such as starch analysis and total sugar
analysis were carried out to determine the starch and sugar content in the sample.
Besides that, spectroscopic characterization was carried out using Fourier Transform
Infrared (FTlR) spectroscopy to detect the functional group presence in the sample for
untreated and steam pre-treated samples. Scanning electron microscopy was done to
observe the anatomical features of binderless particleboard panels of different type
particles using Scanning Electron Microscopy (SEM) from the micrograph taken.
Characteristic such as weight changes in relation to temperature was tested by
Thermogravimetric (TGA) equipment. TGA can also determine the degradation of
binderless particleboard panels. The results showed that binderless particleboard panels
made using strands had higher modulus of rupture (MOR) and internal bond (IB) than
fine particles binderless particleboard panels which were 0.93 MPa and 24.95 MPa
respectively.
