Ağaç malzeme, ahşap yapı sektörü, kent mobilyası ve iç mekân
tasarımından mobilya sektörüne kadar yaygın olarak kullanılan yenilenebilir bir
kaynaktır.  Ağaç malzeme, yanma ve
biyolojik faktörlere dayanım açısından bazı olumsuz özelliklere sahiptir.
Özellikle ahşap yapı ve kent mobilyalarında kullanılan ağaç malzemeler, ürünün
ömrünü uzatmak için yanmaya ve biyolojik faktörlere karşı kaplanır ve/veya
emprenye edilir. Emprenye işleminde retensiyonun arttırılması yanmaya karşı
dayanımı da arttırır. Bu çalışmada sıvı nitrojen uygulamasının retensiyona
etkisi incelenmiştir. Sarıçam ve Doğu ladin odunları vakum-basınç metoduyla
firetex ile emprenye işlemi öncesi 30 dakika süreyle sıvı nitrojene maruz
bırakılmıştır. Sonuçlara göre retensiyon miktarı, doğu ladini ve sarıçam
örneklerinde sıvı nitrojen uygulaması ile arttırılmıştır. Ayrıca, sıvı azotun
mekanik özellikler üzerinde önemli bir olumsuz etkisi olmadığı görülmüştür. Bu
nedenle, sıvı azot muamelesi, odunun emprenye edilebilirliğini iyileştirmek
için etkili bir yöntem olarak uygulanabilir.

The effects of liquid nitrogen treatment on the some physical and mechanical properties of scots pine and oriental spruce wood

Öz

The wood materials widely used from wood construction
sector, urban furniture and interior design to furniture sector are renewable
resource. Wood has some disadvantages regarding durability to combustion and
biological factors. To increase service life especially in urban furniture are
coated and/or impregnated against to fire and biological factors. Thus, the
wood materials used in construction sector should be treated with
fire-retardant chemicals. In this study; Scots pine and Oriental spruce wood materials
were exposed to liquid nitrogen for 30 minutes before impregnated with Firetex
by using pressure-vacuum method. According to the results, amount of retention
in Oriental spruce and Scots pine samples have been increased with liquid
nitrogen treatment. Additionally, it was seen that the liquid nitrogen
operation had not significant adverse effect on the mechanical properties.
Therefore, the liquid nitrogen treatment can apply effectively as a method to
improve the impregnability of the wood.
