عنوان انگلیسی Properties of Medium Density Fiberboard Made from Wet and Dry Stored Bagasse
چکیده انگلیسی مقاله Medium Density Fiberboard (MDF) was produced using moist depithed bagasse stored dry or wet. The duration of storage for either method varied between 0 to 4 months. Two steaming temperatures of 175C and 185C were also used. MDF boards were produced in the laboratory and the common mechanical and physical properties were measured and compared. Results showed that an increased steaming temperature and storage time (especially for the wet storage method) have negative effects on the mechanical properties and positive effects on the physical properties (water absorption and Thickness swell). The mechanical properties of boards produced from bagasse as received (fresh bagasse) and at a steaming temperature of 175C were superior to others. The modulus of Rupture (MOR), Modulus of Elasticity (MOE) and Internal Bond (IB) of boards from fresh ba-gasse were 29.7 MPa., 3,127 MPa., and 0.52 MPa. respectively. However, the physical properties of boards produced from bagasse after 3 months’ wet storage and a steaming temperature of 185oC were superior, and were measured at 44.3% and 63.9% for water absorption after two and 24 hours’ immersion (WA2, WA24 ), and 11.5% and 17.6% for Thickness Swelling after two and 24 hours immersion (TS2, TS24 ) respectively.
