THE EFFECT OF PRODUCTION VARIABLES ON MEDIUM DENSITY FIBERBOARD QUALITY MADE FROM TALABE -ANZALYE REED
In this study, MDF was produced from Reed ( Phragmites australis ). Reeds are collected from Talabe - Anzalye areas. The treatments conditions for fiber preparing were as follows:-Steaming temperature 170°c, 180°c-Steaming time 5, 10, 15 minutesThe other production variables were constant. The anato...

| Summary: | In this study, MDF was produced from Reed ( Phragmites australis ). Reeds are collected from Talabe - Anzalye areas. The treatments conditions for fiber preparing were as follows:-Steaming temperature 170°c, 180°c-Steaming time 5, 10, 15 minutesThe other production variables were constant. The anatomical properties of Reed such as fiber length, fiber diameter, lumen cell diameter, and cell wall thickness were measured respectively 1.38mm, 17.07, 6.15, 5.46 micron. LID ratio of Reed fiber was measured 80.84. The physical and mechanical properties of MDF were determined according to DIN standard. The measurements of bending properties and IB of MDF revealed that increasing steaming time and steaming temperature caused to decrease MOR, MOE and IB.Also the results of MDF dimentional stabilities indicated that Thickness Swelling after 2 and 24 hours decreased upon increasing steaming time and steaming temperature. Degradation of hemicellulose chains may be the reason of decreasing Thickness Swelling. |
