Abstract
Jobs tears (Coix lacryma-jobi) stalk was used as a possible raw material for particleboard. A urea-formaldehyde (UF) resin was synthesised in the laboratory with resin solids at 50 content as a particleboard binder. The physical characteristics of the synthesised UF resin were analysed for solids content specific gravity viscosity gel time pH and free formaldehyde content. The laboratory particleboards were made using Jobs tears stalk and wood particles based on a Jobs tears stalk oven-dry weight of 0 10 20 30 and 40 with UF resin. The physical and mechanical properties of the particleboard were tested according to the ASTM D 1037-99 procedure. Internal bond bending strength properties of the particleboards made using the UF resin decreased gradually with increasing Jobs tears stalk content. However the acceptable physical and mechanical properties of all particleboards showed that Jobs tears stalk is a suitable raw material for manufacturing of particleboard.
