Özet

In this study, polymeric composite particleboard has been manufactured from orange peel, which is an abundant and promising agricultural waste in Turkey. An urea-formaldehyde (95 wt%) and phenol-formaldehyde (5% wt) mixture was used as polymeric binder and waste orange peel as a filler for the production of particleboard. The effect of polymeric binder/filler ratio on the tensile strength, limit oxygen index and water absorption capacity of the composite materials were determined. The molding temperature and pressure were set to 120 degrees C and 2 Mton, respectively. The highest tensile strength was obtained as 15 MPa at an equal polymer/orange peel ratio. Both mechanical strength and LOI (limiting oxygen index) values increased with increasing polymeric binder amount in the particleboard. However, water absorption capacity values decreased from 0.35 g water/g material to 0.16 g water/g material, with increasing amount of the polymeric binder. Considering the properties of the developed polymeric composite material, it can be concluded that orange peel waste can be used as a filler to replace wood-based materials in the production of particleboard.
