“…Alternative fibers, such as agricultural residues and non-wood plant fibers, could play as the leading role in getting balance among supply and demand for the manufacturing of composite panels, such as particleboards [1]. These particleboards are generally manufactured from the agricultural residues, walnut [2], kiwi prunings [3], cotton seed hulls [4], rice straw-wood [5], flax shiv [6], vine prunings [7], walnut, pine cone [8], almond shells [9,10], wood flour [11] sugarcane bagasse and castor oil [12], coffee husk and hulls [13] coconut fiber and castor oil [14] and peanut residues [15].…”

“…It can be deduced from these results that phenol formaldehyde can be mixed with urea formaldehyde to decrease water absorption capacity and swelling increase in the thickness of particleboards. It is thought that these hydrofobic properties result from cross link binding in resin and improving of resin filler adhesion [19]. …”

SUMMARYThe purpose of this study was to manufacture urea-formaldehyde-based particleboard from hazelnut shell and eliminate its disadvantages such as flammability, water absorption, swelling thickness by using fly ash and phenol-formaldehyde. Synthesized urea-formaldehyde and grained hazelnut shells were blended at different ratios ranging from 0.8 to 3.2 hazelnut shell/urea-formaldehyde and dried at 70 • C in an oven until constant weight was reached. In addition, other parameters affecting polymer composite particleboard from hazelnut shell and urea-formaldehyde were investigated to be the amount of fly ash, amount of phenol formaldehyde and the effects of these parameters on bending stress, limit oxygen index, water absorption capacity and swelling in the thickness. The optimization results showed that the maximum bending strength was 4.1N/mm 2 , at urea-formaldehyde ratio of 1.0, reaction temperature of 70 • C, reaction time of 25 min, hazelnut shell/urea-formaldehyde resin of 2.4 and mean particle size of 0.1 mm. Although the limited oxygen index and smoke density of composite particleboard without fly ash has 22.3 and 1.62, with fly ash of 16% (w/w) according to the filler has 38.2 and 1.47, respectively. Water absorption and increase in the swelling thickness exponentially decreased with increasing phenol formaldehyde.

“…It is important to evaluate agricultural wastes to find their particular characteristics, which may also vary as a function of the geographical area where the plant has grown. A wide variety of non-wood plant fibers and agro-residues, such as nutshell, 1 walnut and almond shell, [9][10][11] peach nut shell, 12 kiwi prunings, 13 bamboo, 14 cotton seed hulls, 15 flax shives, 16 vine prunings, 17 wood flour, 18 rice husk and starch, 19,20 Todo fir, sycamore leaves and sun flower, have been investigated as filling materials. [21][22][23] In the literature, studies on a number of parameters, such as curing time and temperature of the polymeric binder, 1,9 molding temperature and pressure, polymeric binder/filler ratio 10,12 and particle size of the filler, 24 have been carried out to find the optimum conditions for resin synthesis and to enhance the physical and mechanical properties of particleboard.…”

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 °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.
