Abstract

In this study, MDF was produced from wet depicting Bagasse in three steaming time of 5, 10 and 15 minutes and in two steaming temperatures of 170°C and 180°C. There were 6 treatment conditions by combination of the above factors and three replications for each combination which resulted in producing 18 boards.
The anatomical and chemical properties of Bagasse and also the physical and mechanical properties of MDF such as MOR, MOE, IB and swelling thickness after 2 and 24 hours were studied.
Fiber length, fiber diameter, lumen cell diameter, and cell wall thickness were respectively measured 1.24 mm 22.90m., 12.48 m and 5.28m cellulose, lignin, extractives, and ash contents were 53.68%, 20.44%, 0.96% and 1.14% respectively.
The measurement of MOR, MOE, IB and SW (after 2 and 24 hours) of the MDF revealed that the proper condition is obtained at the steaming temperature of 170°C and the steaming time of 5 minutes. The properties in the above-mentioned conditions were measured 12.22Mpa, 1370 Mpa, 0.13 Mpa, 47.11% and 52.22% respectively.
