“…As previous research has pointed out, the oxygen-free conditions when using the vegetable oil medium and the certain level of oil uptake for the modified wood seem to be the key factors for the improvement of wood properties. (Stamm, 1956;Cheng et al, 2014). In order to improve the performance of bamboo, Cheng et al (2013) also successfully increased the mold resistance of bamboo using a two-step heat treatment method.…”

“…The idea of ethanol extraction on the oil heat treated wood was derived from the vegetable oil industry, in which solvent extraction has been the primary means of extracting vegetable oil from oleaginous materials. The possibility and other information about the ethanol extraction on oily wood have been presented in the coauthor's previous published paper (Cheng et al, 2014). The objective of this paper was to apply oil extraction with ethanol, based on the above coauthor's research on oil heat-treated wood (Cheng et al, 2014), to improve the oily bamboo surface and thereby improve the interface properties of oil heat-treated bamboo.…”

Following extraction, the wettability of the bamboo skin and bamboo pith surfaces, measured by the contact angle of distilled water, was quantitatively compared for untreated bamboo, oil heat-treated bamboo, and oil heat-treated bamboo extracted with ethanol.…”

ÖZET: Masif ahşap malzemeyi bozucu zararlılara karşı korumak için bazı farklı metotlar kullanılmaktadır. Bunun yanında, odunun fiziksel özelliklerini modifiye etmek için ısıl işlem modifikasyonu gibi bazı metotlar da kullanılmaktadır. Endüstriyel uygulamalarda, ısıl işlem modifikasyonunun kullanımı son on yılda artmıştır. Toros göknarı (Abies cilicica) odunu biyolojik olarak çok çabuk bozulabilir bir odundur ve farklı alanlarda kullanılmadan önce bazı koruyucu maddelerle muamele edilir. Bu çalışmada, Toros göknarı sıcak bitkisel yağ ile 160, 180, 200 ve 220°C sıcaklıklarda muamele edilmiştir. İşlem sonrası, odunun, ağırlık artışı, yoğunluk, denge rutubeti miktarı, teğet yönde şişme, radyal yönde şişme ve hacmen şişme, lif doygunluk noktası gibi bazı fiziksel özellikleri belirlenmiştir. Ayrıca, ağırlık artışı ile genişleme yüzdeleri arasındaki ilişki belirlenmiştir. Gruplar arasındaki istatistiksel olarak önemli farklar ANOVA kullanılarak belirlenmiştir. Elde edilen bulgulara göre; ağırlık artışının ve diğer fiziksel özelliklerin sıcaklık arttıkça azaldığı belirlenmiştir. Anahtar kelimeler: Yağ ısıl işlemi, Toros göknarı, fiziksel özellikler Some Physical Properties of Taurus Fir Wood (Abies cilicica) Treated with Hot VegetableOil ABSTRACT: Some different methods are used to protect solid wood materials from destructive pests. In addition, some methods are used to modify the physical properties of wood, such as thermal modification. The use of thermal modification in industrial applications has increased in the last decade. Taurus fir (Abies cilicica) wood is a very vulnerable wood, and it is treated with some preservatives before being used in many different areas. In this study, the Taurus fir wood was treated with hot oil at temperature of 160, 180, 200 and 220°C. After the treatment, some physical properties of the wood were determined, e.g., weight gain, density, equilibrium moisture content, tangential swelling, radial swelling, and volumetric swelling, fiber saturation point. In addition, the relationships between weight gain and swelling percentage were determined. The statistically-significant differences between groups were determined using ANOVA. According to obtained data; it was determined that the weight gain and other physical properties decreased as the temperature increases.
