| Summary: | Particleboard made from tropical wood wastes bonded with12% urea
formaldehyde added with hardener (Ammonium Chloride). The study carried out
about the boards that fabricated with three different particle sizes «1 mm),
(>1 mm) and mixture from below and upper than 1mm. The boards produced
was evaluated for its bending properties, internal bonding (IB), water absorption
(WA), thickness swelling (TS) and screw withdrawal (SW) in according with
Malaysian Standards. The screw withdrawal testing was made on two
orientation of the board which is the surface and the edge. The study revealed
that the mixed particle size shows the best bending strength, TS and WS. The
board with particle size «1 mm) shows the highest internal bonding (IB). (>1 mm)
board gives high screw withdrawal strength rather than «1 mm) and mixed
particle size. |
