Yıl 2017, Cilt: 19 Sayı: 1, 187 - 193, 01.06.2017

Öz

Bu çalışmada, sarıçam (Pinus sylvestris L.) ve Uludağ göknarı (Abies bornmulleriana Mattf.) odunlarının bazı özellikleri üzerine ısıl işlemin etkisi araştırılmıştır. % 65 nispi nem ve 20 ° C sıcaklıkta şartlandırılan ahşap numuneler, 190 °C' de 4 saat süreyle ısıl işleme tabi tutulmuştur. Isıl işlemden sonra yoğunluk, su alma, boyutsal stabilite, renk değişiklikleri ve FTIR analizi tespit edilmiştir. Test sonuçlarına göre ısıl işlem görmüş her iki ağaç türünde yoğunluk, su alma ve hacimsel genişleme değerlerinde düşme gözlenmiştir. Hacimsel genişlemenin en fazla teğet, ardından sırasıyla radyal ve boyuna kesitte olduğu tespit edilmiştir. Isıl işlem uygulamasıyla birlikte ağaç malzemede renk değişimi gerçekleşmiştir. Sarıçam odununun, Göknar odununa kıyasla daha fazla renginin koyulaştığı belirlenmiştir. Isıl işlem sonrası FTIR spektroskopunda görülen analiz sonuçlarına göre 900, 1025, 1030, 1050 ve 1505 cm-1 ve 1737 cm-1 pikleri tespit edilmiştir. Pikler arasında önemli bir değişim olmadığı saptanmıştır.

The Effects of Thermal Treatment on the Some Properties of Scots Pine and Uludağ Fir Woods

Yıl 2017, Cilt: 19 Sayı: 1, 187 - 193, 01.06.2017

Öz

In this study, the effects of heat treatment on some properties of Scots
pine (Pinus sylvestris L.) and Uludağ fir (Abies bornmulleriana
Mattf.) woods were investigated. Wood specimens conditioned at a relative
humidity of 65% and a temperature of 20°C were subjected to heat treatment at
190 for 4 h. After heat treatment, density, water absorption, dimensional
stability, color changes, and FTIR analysis were determined. According to the test results, the
density, water uptake and volumetric swelling values of both heat treated wood
species decreased. It was determined that the volumetric swelling was maximum
at tangential, followed by radial and longitudinal directions. Color change
occurred in wood material together with heat treatment. It has been seen that
the color of the deciduous wood is darker than that of the fir. According to
the results of FTIR spectroscopy after heat treatment, it was determined that
900, 1025, 1030, 1050 and 1505 cm-1 and 1737 cm-1 peak.
It was determined to be not significant difference among the samples.
