Özet:

 The aim of this study was to determine some physical and mechanical properties of spruce Picea orientalis wood, which was impregnated with aqueous solutions of valonia valex the extract of Quercus ithaburensis, pine bark powder pinex Pinus brutia Ten. and gallnut powder galex Quercus infectoria Oliver as a pre-treatment and then heat treated. Test specimens were prepared from sapwood of spruce wood and impregnated with 10 tannin solutions before heat treatment base on ASTM D 1413-76. After pre-impregnation processs, specimens subjected to heat treatment at 150 C, 175 C and 200 C for 2 h. The effect of impregnation process and heat treatment temperature on the air-dried density, compressive strength paralell to the grain CS, bending strength MOR and modulus of elasticity in bending MOE were analyzed. As results, impregnation solutions showed positive effects on mechanical strength in unheat-treated samples and determined that mecnaical strength loses due to heat treatment slightly limited at low temperatures. However, strength loses increased with increasing temperature. The highest strength loses were also determined in impregnated samples with galex extract and heat-treated samples at 200 C.

 Bu çalışmanın amacı, ön işlem olarak meşe palamudu valex Quercus ithaburensis, kızılçam kabuğu pinex Pinus brutia Ten. ve meşe mazısı galex Quercus infectoria Oliver ekstraktlarının sulu çözeltileri ile emprenye edildikten sonra ısıl işleme tabi tutulan ladin Picea orientalis odunun bazı fiziksel ve mekanik özelliklerinin belirlenmesidir. Test örnekleri, ladin ağacının diri odun kısmından hazırlanmış ve ısıl işlemden önce ASTM D 1413-76ya göre 10 tanen çözeltileri ile emprenye edilmiştir. Ön emprenye işlemlerinden sonra, test örnekleri 150 C, 175 C ve 200 Cde 2 saat süreyle ısıl işleme tabi tutulmuştur. Emprenye ve ısıl işlemin hava kurusu yoğunluk, liflere paralel basınç direnci CS, eğilme direnci MOR ve eğilmede elastikiyet modülüne MOE etkileri analiz edilmiştir. Sonuç olarak, emprenye çözeltilerinin ısıl işlem uygulanmamış örneklerinde mekanik özellikleri olumlu etkilediği ve düşük sıcaklıklarda ısıl işlemden kaynaklanan direnç kayıplarını bir miktar sınırladığı tespit edilmiştir. Ancak artan sıcaklıkla beraber direnç kayıpları da artmıştır. En yüksek direnç kayıpları, galex ile emprenye edilmiş ve 200 Cde ısıl işlem uygulanmış örneklerde tespit edilmiştir.
