Abstract

Thermo process is without using chemical material for modification method of wood and was recently introduced to Turkey. This study was conducted to determine some technological properties of the applied heat treatment wood materials blackpine ( Pinus nigra var. pallasiana ) and ash ( Fraxinus exelsior L. ) wood. Thereafter each sample was tested for observation of air dry density, oven dry density,  volumetric swelling, volumetric shrinkage, water permeability and torsion were determined.  The results indicated that the heat treatment method decreased   the air dry density and oven dry density. However, important increase was observed for volumetric swelling, volumetric shrinkage, water permeability and torsion strenght value. 

Özet

Termo-işlem (thermo-process) kimyasal madde kullanmadan ağaç malzemenin modifikasyonu için kullanılan bir yöntemdir ve endüstriyel anlamda Türkiye’de yeni uygulanmaya başlamıştır. Bu çalışmada; karaçam ( Pinus nigra var. pallasiana ) ve dişbudak ( Fraxinus exelsior L. ) odunlarına ısıl işlem uygulamasının odunlarda hava kurusu yoğunluk, tam kuru yoğunluk, boyutsal çalışmalardan hacimsel değişim (şişme ve çekme), su geçirgenliği ve çarpılma (burulma) özellikleri belirlenmiştir.  Çalışma sonucunda; ısıl işlem uygulamasının ağaç malzemelerin hava kurusu yoğunluk ve tam kuru yoğunluk özelliklerini önemli oranlarda düşürmüştür. Bununla beraber hacimsel çekme ve şişme, su geçirgenlik direncinde önemli derecede direnç artışı olurken ağaç malzemenin çarpılma veya burulma özellikleri üzerine de olumlu etkisinin olduğu görülmüştür.
