چکیده طرح پژوهشی:
In this study two factors (resin content, press time) on properties of MDF was investigated. Variation of each variable was as follow: - Resin content ( 8 , 9.5 , 11 percent ) - Press time ( 4 , 5 , 6 minutes ) The statistical analysis proved that the effect of press time on MOE and MOR was significant . MOE and MOR were the highest at press time of 6 minutes. According to Duncan s test, there isn t any significant differences between MOE at press time of 5 and 6 minutes. Also the effect of resin content on MOE had significant differences. MOE was the highest at resin content of 11%. There isn't any significant differences between MOE on resin content at 9.5% and 11% levels. The results showed that independent effects of press time and resin content had significant differences on IB. IB was the highest at press time of 6 minutes and resin content of 11%. There isn t any significant differences between IB on resin content at 9.5% and 11%. The independent effects of press time and resin content had significant differences on thickness swelling after 2 hours. Thickness swelling was the lowest at press time of 6 minutes and resin content of 11%. The results recommend that optimum combination for MDF producing from baggasse consist of resin content and press time are 9.5% and 5 minutes respectively. Keywords: Press time, Resin content, MDF, MOR, MOE, IB.
