| Summary: | In this investigation, particleboard manufacturing has been offered considering usage of lignocellulosic residues from recision of pomegranate trees in particleboard production using pomegranate and poplar(P.nigra) wood with 4 different combination (1. 100% of pomegranate wood 2. 75% of pomegranate wood and 25% of poplar wood 3. 50% of pomegranate wood and 50% of poplar wood 4. 100% of poplar wood as the control sample ) and using 2 resin consumption levels UF (10 & 12 %) and 2 press time levels (4&5 min.). According to these factors, 16 combination samples were totally collected and 3 boards from each treatment totally 48 experimental sample boards were made. The result of physical and mechanical properties were analyzed using Randomized Complete Block experimental Design ( RCBD ). The result of this investigation showed that Modulus of Rupture (MOR) in boards has effectively reduced while increasing the press time. On the other hand , resin consumption content and press time have a direct impression on Modulus of Rupture (MOR) and Modulus of Elastisity (MOE) in boards so that MOR and MOE decreased while 10% resin consumption and increasing the press time. These results also indicated that MOR and MOE of the boards have increased by adding poplar particles to the wood combination for board production. Indeed, Internal Bonding (IB) of boards has modified while 10% resin consumption and increasing the press time but IB has effectively decreased by 12% resin consumption and increasing the press time. Anyway, all the Internal Bonding average values for boards have been higher than the standard level. The results also showed that Thickness Swelling (TS) of boards has increased by adding poplar particles to the wood combination for board production. |
