Abstract

In this research the effects of ACETYLATION and PRESS TEMPERATURE on mechanical properties of medium density fiberboard (MDF) were investigated. Sample boards were made from acetylated POPLAR FIBERS, which were treated with different weight percent gains (WPGs of 0, 2.22, 15.97, and 19.08%) at two PRESS TEMPERATUREs (170 & 185 oC). The results were analyzed based on a complete randomized design (CRD) under a factorial experiment with two factors (WPG & PRESS TEMPERATURE). Results showed that the ACETYLATION increased MOR and MOE in MDF. The MOR and MOE properties were determined as 17.80MPa and 2184.17MPa in the acetylated boards (19.08% WPG) and 17.48MPa and 1793.5MPa. in untreated boards respectively. Internal bond strength (IB) was higher in acetylated boards than in controls. The IB in the boards, which were made at 185oc PRESS TEMPERATURE, was determined as 0.44MPa in the acetylated MDF with the highest WPG (19.08%) and 0.29MPa in the control boards.
