Endüstriyel Isıl İşlemin Dişbudak (Fraxinus excelsior) Odununun Boyutsal Stabilite ve Islanabilirliği Üzerine Etkisi

Çalışmada, endüstriyel ısıl işlem uygulamasının dişbudak (Fraxinus excelsior) odununun boyutsal stabilite ve dinamik ıslatma özelliği üzerine etkisini incelemektir. ThermoWood prosesine göre 210 derece 120 dakika boyunca ısıl işlem görmüş Dişbudak numuneleri kullanılmıştır. Çalışmada 20x20x30 mm boyutlarına sahip 15 adet ısıl işlem görmüş numune 15 adet ısıl işlem görmemiş numune olmak üzere toplam 30 numune biçilmiş ve dinamik ıslatma özelliği ile boyutsal stabilite özellikleri incelenmiştir. Çalışmada elde edilen bulgular, ısıl işlem uygulaması ile birlikte ağaç malzemenin ıslanabilme özelliğinin azaldığını göstermiştir. Özellikle radyal kesite nazaran teğet kesitte boyutsal kararlılığın daha yüksek olduğu tespit edilmiştir. Ayrıca dinamik ıslatma özelliği ile boyutsal kararlılık arasında önemli bir korelasyon olduğu belirlenmiştir.

The Effect of Industrial Heat Treatment on The Wettability and Dimensional Stability of Ash (Fraxinus excelsior) Wood

In this study is to examine the effect of industrial heat treatment application on the dimensional stability and dynamic wettability properties of ash (Fraxinus excelsior) wood. Ash samples that were heat treated for 120 minutes at 210 degrees according to the ThermoWood process were used. In this study, a total of 30 samples, including 15 heat treated samples with dimensions of 20x20x30 mm, and 15 unheat treated samples were cut and the dynamic wettability and dimensional stability properties were examined. The results obtained in the study showed that the wettability property of the wood material decreased with the application of heat treatment. It has been determined that the dimensional stability is higher especially in tangential section compared to radial section. It was also found that there is a significant correlation between dynamic wettability property and dimensional stability.
