چكيده لاتين :
In this investigation, the influenee of press temperature and press time on MDF properties made from
Eucalyptus wood (Eucalyptus tntertexta sp,) have been studied. Variable factors were steaming time (in
two levels: 5 and 10 minutes), press temprature (in two levels: 180 and 190 OC) and press time (in three
levels: 3. 3.5 and 4 minutes). The results of this study indieated that the effect of steaming time on MOR
had been significanted, the highest MOR were obtained 14.62 Mpa in MDF boards that produeed in 5
minutes steaming time. Also the MOR of boards were increased with ascending of press temperature. The
results also showed that the effeet of press temperature on MOE had been signifieanted and MOE of
boards were increased with ascending of press temperature. The results revealed that increasing of
steaming time and press time had negative effect on lB. on the other hand press time had a significant
effect on thickness swelling as the minimom ofthickness swelling had obtained in 3 minutes press time.
