Özet
In this study, the effect of heat treatment on dimensional stability of ash (Fraxinus angustifolia Vahl.) wood, which naturally grows in Turkey, was investigated. Ash wood samples were subjected to the heat treatment process at different temperatures (120 degrees C, 160 degrees C, 190 degrees C, and 210 degrees C) and for different time periods (3, 6 and 9 h) in water vapor atmosphere. Water absorption, water repellent effectiveness, anti-swell effectiveness (ASE, TS 4084) and Attenuated Total Reflection - Fouirer Transform Infrared Spektrofotometre (ATR-FTIR) were performed on the test samples. Generally, although water absorption decreased with an increase in treatment temperature and time period, the mean of water repellent effectiveness and ASE increased. It was determined that decreases in the absorbance value of the peak belong to the -OH stretching vibration depended on heat treatment temperature increases. In particular, ASE increased to >40% with a rapid increase after 3 hours application of heat treatment at 190 degrees C. The highest dimensional stability (58.4%) of ash wood was detected in the highest heat treatment temperature and time period (210 degrees C and 9 h, respectively). Therefore, it was shown that the value and product quality of solid products produced from ash wood with heat treatment can be improved without the use of toxic chemicals.
