This research examined the potential for using peanut husk as a fiber alternative to wood in the production of melamine-formaldehyde (MF) particleboard. MF resin was used to produce panels with one, three, six, nine or 12 percent resin contents. Modulus of Rupture (MOR), Modulus of Elasticity (MOE), Internal Bond (IB)...
The substantial increase in resin costs due to the recent energy
crisis, increased public awareness to the problem of free formaldehyde
from boards bonded with urea-formaldehyde resins, and a projected
increase in the production of exterior board have emphasized the need
for new and substitute adhesive systems. One new development...
Competition for the conventional supply of wood residue utilized
by the particleboard industry is increasing. Utilization of low
quality residues by the pulp and paper industry, new sawmill and
plywood recovery techniques, and the growing practice of converting
low quality residues into steam and electrical power have all cut into...
Nonlocal theories of continuum mechanics are used to model the
fracture behavior of particleboard in tension perpendicular to the plane
of the board. Classical theories of fracture are examined in comparison
to a nonlocal crack solution which has removed the stress singularity
at the crack tip. With the removal of...
Past research has implied that differences in blender performance
between commercial and laboratory particleboard blenders
may not be attributed to resin distribution between screen fractions,
as is commonly believed in the industry today, but to which particles
within a screen fraction have resin and which do note
To test this,...
The ability of the resin to deform plastically can be an
important factor when considering the mechanical properties of particleboard.
Between resin droplets there exists an unbonded region
that forms the surface for a crack. When particleboard is deformed
stress concentrations develop at the crack tips in the voids. A...
