Absorption differences of Corsican pine and Sıtka spruce treated with tanalith-C

Bu çalışmada, İngiliz yumuşak ağaç türlerinden Korsika çamı {Pinus nigra var. maritima (Ait.) Melville) ve Sitka ladini {Picea sitchensis (Bong.) Carr.) türlerinin koruyucu sıvı içerme düzeyleri dolu hücre yöntemiyle yapılan aynı koruma koşulları (5 dakika 640 mmHg vakum ve 5 dakika 6 bar basınç) ile (i) diri odun ve öz odunu ve (ii) Uç farklı anatomik geçirgenlik yönü bağlamında araştırıldı. Geçirgenlik özellikleri ağaç malzeme boşluk hacminin tanalith-C tarafından doldurulma yüzdesi gözönüne alınarak aşağıdaki gibi sıralandı: (i) İki ağaç türünün diri odunu ile öz odunu arasında koruyucu sıvı içerme düzeyi bakımından oldukça önemli farklılığın olduğu görüldü. Korsika çamı'nın Sitka ladini'ne göre daha fazla geçirgen olduğu belirlenirken koruyucu sıvı içerme düzeyinin her iki türde de öz odununa göre diri odunda daha yüksek olduğu saptandı, (ii) Her iki ağaç türünde de üç farklı anatomik sıvı akma yönü arasında oldukça önemli farklılığın olduğu görüldü. Sıvı akma yönlerine göre yapılan koruyucu sıvı içerme düzeyi sıralaması her iki türde de çoktan aza doğru boyuna>teğet>radyal şeklinde belirlendi. Buna ek olarak, her yön için yapılan karşılaştırmada Korsika çamı'nın koruyucu sıvı içerme düzeyi bakımından Sitka ladini'ne göre daha yüksek olduğu saptandı.

Tanalith-C ile korunmuş Korsika çamı ve Sitka ladini türlerinin içerme farklılıkları

Absorption differences of the two British softwood species, Corsican pine {Pinus nigra var. maritima (Ait.) Melville) and Sitka spruce {Picea sitchensis (Bong.) Carr.), were examined on the basis of (i) sapwood and heartwood, and (ii) the three structural directions of sapwood under the same treatment condition of the full-cell process (i.e. 640 mmHg vacuum and 6 bar pressure for 5 minutes). Accordingly, conclusions on indication of the flow characteristics are listed separately for the general purpose of the work on account of the percentage of void volume filled by tanalith-C: (i) Significant differences between the two species within a set of triple flow on sapwood and heartwood. The penetration of sapwood was much greater than that of heartwood, although Corsican pine was more readily treated according to Sitka spruce in either zones, (ii) Very highly significant differences among the three structural directions in both species showing the descending order of the fluid absorption as longitudinal>tangential>radial, although in that any cases Corsican pine was much more permeable than in Sitka spruce.
