Bu çalışmanın amacı, ısıl işlem görmüş Kayın (Fagus orientalis) ve Meşe (Quercus robur) odunlarının bazı özellikleri üzerine nano boyutlu Titanyum dioksit ve Bor nitrür ile emprenyenin etkilerini araştırmaktır. Ahşap materyallerin ısıl işlemi hava ortamında bir etüvde gerçekleştirilmiştir. Emprenye işlemi, bir tankta dolu hücre metodu kullanılarak ahşap malzemelere uygulanmıştır. Emprenye işleminden sonra; örnekler, % 65 bağıl nem ve 20 °C sıcaklığa sahip bir ortam oluşturulan iklimlendirme kabininde bir ay boyunca kurutulmuştur. Elde edilen örneklerin %0 ve %12 denge rutubetinde (MC) yoğunluklar, su alma ve boyutsal kararlılığı ilgili standartlara göre belirlenmiştir. Sonuçlar ahşabın nano bor nitrür ile emprenye edilmesinin ve ısıl işlemin genellikle odun-su ilişkilerini azalttığını göstermiştir. Ahşap materyallerin ısıl işlemi, su alma ve boyutsal kararlılığındaki düşüşte nano partikül emprenyesine göre daha önemli bir faktör olduğu belirlenmiştir. TiO2 ile yapılan emprenyenin, nano bor nitrür ile yapılan emprenyeye göre ahşap numunelerin daha fazla su almasına sebep olduğu belirlenmiştir.
The aim of this study is to explore the effects of the empressor with nano-dimensional titanium dioxide and bor nitrate on some characteristics of heat-processed Fagus (Fagus orientalis) and Quercus (Quercus robur) wood. The heat processing of wood materials is carried out in an air environment. The printing process is applied to wooden materials using a cell-filled method in a tank. After the processing, the samples were dried for a month in the air conditioning cabin, which was created with a connection moisture of 65% and a temperature of 20 °C. In the 0% and 12% balanced ratings (MC) of the samples obtained, the intensity, water absorption and dimensional stability are determined according to the relevant standards. The findings showed that the wood was imprisoned with nano-bor nitrate and that heat processing often reduced the wood-water relationships. It has been determined that wood materials are a more important factor in heat processing, water absorption and decrease in dimensional stability than nano particle empeny. The empression made with TiO2 has been determined to cause wood samples to get more water according to the empression made with nano bor nitrate.
The aim of this study is to investigate to the effects of impregnation with nano sized titanium dioxide and boron nitride on some properties of heat-treated Beech (Fagus orientalis) and Oak (Quercus robur) woods. Heat treatment of wood materials were conducted in an oven under air medium. The impregnation process was applied to wood materials by using full-cell method in a chamber. After impregnation process, the samples were dried in the climate cabin created the medium such as 65% Rh and 20°C during a month. The densities at 0% and %12 moisture content (MC), water absorption and dimensional stability of the obtained samples were determined according to the related standards. The results showed that the impregnation of wood with nano boron nitride and heat treatment of wood generally decreased the water-wood relations. The heat treatment of wood materials was determined to be more an important factor on the decrease of water absorption and dimensional stability as comparison with the nanoparticle impregnation. The impregnation with TiO2 was also found to increase the water absorption according to the impregnation with nanoboron nitride
