Potential Use of Olive Stone Residues in Particleboard Production

In this study, the effect of using olive stone residues (OSR) on some properties particleboard was investigated. For purpose, particle boards were manufactured from particles white poplar (Populus Alba L.), which partially substituted with OSR in amounts 10 %, 20 % and 30 %. addition, containing OSR, had previously been chemically modified NaOH solution, produced. Phenol formaldehyde adhesive used production boards. Chemical wood (pH, alcohol benzene solubility, amount ash), physico-mechanical (density, moisture content thickness swelling, modulus rupture, elasticity internal bond strength) emission values determined. Water absorption swelling generally decreased increase use OSR. When usage bending strength, elasticity, perpendicular tensile strength examined, a decrease observed except for ratio. As result application alkali pretreatment, an observed, while mechanical increased. Scanning electron microscopy (SEM) analysis results showed more spaces between increasing Formaldehyde increased slightly alkaline pretreatment. Based findings we can conclude that be at particularly low ratio production.
