Ahşabın fiziksel, Kimyasal, mekaniksel ve biyolojik özellikleri üzerine ısıyla muamelenin etkisi

Öz:
Odunun ısıtılması eski çağlardan beri ahşabın kurutması ve özelliklerin modifiye edilmesinde kullanılan bir metottur. Günümüzde de ısı muamelesi aynı nedenlerden dolayı endüstriyel olarak kullanılmaktadır. 150 °C ve üstündeki sıcaklıklardaki muamelelerle odunun rengi değiştirilebilmekte, biyolojik direnç ve boyutsal stabilizasyon iyileştirilebilmektedir. Fakat odunun mekaniksel özelliklerinde kayıplar olmakta ve odunun kimyasal yapısı değişmektedir. Bu dezavantaj ısıyla muamele edilmiş odunun, kullanım yerini sınırlamaktadır. Dünya’da en yaygın kullanılan muamele metodu “Thermowood” olarak adlandırılmakta ve muamele su buharı altında yapılmaktadır. Bu yöntem Finlandiya’da kullanılan ve patenti de bu ülkeye ait olan endüstriyel bir metottur. Bu çalışmada, ahşabın fiziksel, kimyasal, mekanik ve biyolojik özellikleri üzerine ısıyla muamelenin etkisi araştırılmıştır.

The effect of heat treatment on physical, chemical, mechanical and biological properties of wood

Öz:
Since ancient times, heating wood has been used a method to dry and modify its properties. Nowadays, heat treatment is used in industrial processes for the same reasons. Treatment at temperatures above 150 °C can change the color, improve resistance to biodegradation and enhance dimensional stability. However, losses in the mechanical and technological strength of wood may also occur, and this drawback is a limitation for the use of heat-treated wood in a broad range of products. The treatment method used in the world is called “Thermowood” and this method can industrially applied in Finland. The method involves heating wood in a steam atmosphere where the heat causes chemical changes in the structure of the wood. In this study, the effect of heat treatment on wood properties was investigated.
