Tensile Strength of Monolayer Particleboards Produced from Date Palm Midrib Chips Bonded with Urea Formaldehyde

Systematic laboratory-scale experiments were carried out to study the technical feasibility of producing monolayer particleboards using midribs of Saudi Arabian date palm tree branches (Phoenix dactylifera-L) as raw material. Chips produced from midrib and impregnated with a predetermined proportion of urea formaldyhde binder were hot-pressed under constant pressure (3.25 N/mm²), temperature (180°C) and press cycle times of 5, 7, and 9 min. Experimental particleboard specimens subjected to mechanical tests exhibited satisfactory tensile strength levels. Strength was enhanced phenomenally by improving the particle quality and optimizing experimental variables. Electron microscopy and EDX data on the internal structure of the midribs are also reported.     

Physical Properties of Particleboard Panels Manufactured from Phoenix Dactylifera-L (Date Palm) Mid-rib Chips using Ureaformaldehyde Binder

Pertinent physical properties of experimental particleboard specimens produced from date palm (Phoenix dactylifera-L) branch mid-ribs chips impregnated with ureaformaldehyde (UF) polymer binder are investigated. The effect of process variables (press temperature, pressure, press cycle time and particle thickness) on thickness swelling, water absorption, equilibrium moisture content (EMC) and panel density are presented graphically and discussed in terms of process variables, internal structure of particles and UF-aqueous environment interactions. Scanning electron microscopy (SEM) data on the internal structure of date palm branch mid-ribs are also reported.
