| Abstract | ||
| The purpose of this study was to utilize rose flower stem residues in the core layer of particleboard. Three press temperatures of 160, 170 and 180 C and five percentages of rose stem pruning (0, 25, 50, 75 and 100%) in the core layer were used in the production of poplar wood particleboard. Mechanical and physical properties were measured and analyzed applying factorial experiment and complete randomized design.The results indicated that modulus of rupture (MOR) and modulus of elasticity (MOE) of the boards significantly decreased by increasing rose stem particles in the core layer and press temperature did not show any significant effect on MOR and MOE of the boards. However, the addition of rose stem particles in the core layer deteriorated the IB of the boards and the lowest value was attributed to 100% stem residues in core layer. Also, by increasing of rose stem particles in core layer, thickness swelling after 24 hours immersion in water increased significantly and showed irreversible behavior to IB of the boards. The results showed that the incorporation of this residues to particleboard furnish will not reduce the properties of the board and it met the standard requirements. Our finding confirmed that agricultural residues can be used in combination with conventional raw materials in particleboard production. | ||
