Çeşitli emprenye maddeleri ile muamele edilen kayın odunun yoğunluğu, eğilme direnci ve elastikiyet modülü

Bu çalışma, çeşitli emprenye maddesi grupları ile muamele edilen kayın odununda; yoğunluk, eğilme direnci ve elastikiyet modülü değerlerinin belirlenmesine yönelik olarak hazırlanmıştır. Araştırmada, bor bileşiklerinden borik asit (BA), boraks (Bx) ve BA+Bx karışımı; ticari emprenye maddelerinden amonyum sülfat (AS), diamonyum fosfat (DAP) ve vaksol (V); odun hücre çeperlerini genişletme özelliğine sahip polietilen glikol- 400 (PEG-400), su itici maddelerden (SİM) stiren (St), metilmetakrilat (MMA), St+MMA karışımı ve izosiyanat (ISO) kullanılmıştır. Deney sonuçlarına göre; en yüksek retensiyon oranları su itici maddeler, bor bileşikleri ve PEG-400 üzerine uygulanan ikincil su itici madde muamelesi ile elde edilmiştir. Özgül ağırlık değerleri, su itici maddelerin yalnız başına ve bor bileşikleri üzerine ikincil olarak uygulanması durumunda istatistiksel anlamda önemli derecede artmıştır (P

Specific gravity, bending strength and modulus of elasticity of beech wood (Fagus orientalis Lipsky) treated with some wood preservatives

This study was designed for determination of specifıc gravity, bending strength and modulus of elasticity values of beech wood treated with borates such as boric acid (BA), borax (Bx), BA+Bx mixture (7:3; weight:weight) and commercial preservative types chemicals such as ammonium sulphate (AS), di ammonium phosphate (DAP) vacsol (V), and water repellent chemicals (WR) such as styrene (St), methylmetacrylate (MMA), St+MMA mixture, icocyanate (ISO) and have a bulking effect cell wall in wood such as polyethylene glycol-400. Results indicated that the highest retention levels were obtained wood specimens treated with water repellents and secondary treatments on borates with water repellents. Specific gravity values of specimens were highly increased statistical levels treated with sole vvater repellent treatments and secondary vvater repellent treatments on borates (P
