| Sumario: | Investigation on the Effect of Resin Gradient Consumption on Particleboard Properties Made Using Rose Flower Stalks Residues Abolfazl Kargarfard *Associate Prof., Wood and Paper Science and technology Research Division, Research Institute of Forests and rangeland, Tehran, Iran, kargarfard@rifr-ac.irAbstractThe potential of rose flower stalks for the production of particleboard was investigated. Three resin dosage gradients of 0, 2 and 4% (10% core: 10% surface; 9%core:11% surface and 8% core:12% surface) and three press times (3, 4 and 5 minutes) were selected as the variables and boards were produced. Then the mechanical and physical properties of the boards were measured and statistically analyzed. The results of modulus of rupture (MOR), modulus of elasticity (MOE) and internal bonding (IB) measurements showed that as the resin dosage gradient increases, these properties improved and boards produced using either 2 or 4% resin dosage gradients generated the highest values. The effect of resin dosage gradient on these properties was statistically significant. As the resin dosage gradient increases, both thickness swelling after 2 and 24 hours immersion in water was improved. The effect of press time on thickness swelling after 2 and 24 hours immersion in water was also statistically significant and these properties were improved when 5 minutes press time was used The results indicate that if 2 or 4% resin dosage gradients and either 4 or 5 minutes press time is applied for the manufacturing of particleboards using rose flower stalks residues, the specification of the boards will meet the EN specification.Keywords: Particleboard, Rose flower stalks, Resin dosage gradient, Mechanical Properties, Physical Properties |
