TI  - Effect of heat treatment on the dimensional stability of ash (Fraxinus angustifolia Vahl.) wood
AB  - 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 treatmentprocess at different temperatures (120°C, 160°C, 190°C, and 210°C) and for different time periods (3, 6 and 9h) 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 performedon the test samples. Generally, although water absorption decreased with an increase in treatmenttemperature and time period, the mean of water repellent effectiveness and ASE increased. It was determinedthat decreases in the absorbance value of the peak belong to the -OH stretching vibration depended on heattreatment temperature increases. In particular, ASE increased to >40% with a rapid increase after 3 hoursapplication of heat treatment at 190°C. The highest dimensional stability (58.4%) of ash wood was detectedin the highest heat treatment temperature and time period (210°C and 9 h, respectively). Therefore, it wasshown that the value and product quality of solid products produced from ash wood with heat treatment canbe improved without the use of toxic chemicals.
