| Sumario: | This research was conducted to investigate the posibility of producing particleboards using surface activation method of P. deltoides particles and then using cross-linking agents to bond wood particles. At first, nitric acid as an oxidative agent at different proportion including 0, 3, 4.5 & 6 percent (based on OD weight of wood) and two assembly times of 0 and 1 hour was used. Black liquor at two amounts of 5 and 7 percent was used as cross-linking agent. The results indicates that using 6% nitric acid and 7% liquor had the best performance and that, the assembly time of 1 hour had negative effect on all properties. The ATR spectrum of treated samples showed the increase in the absorbtion rate at 1740 cm-1 related to COOH group as compared with control samples. In addition, the spectrum indicated that increasing oxidation increase absorbtion rate of COOH group. |
