Sibirya Çamı (Pinus sibirica) Odununda Beyazlık İndeksi, Renk ve Parlaklık Değerleri Üzerine Doğal Yaşlandırma Etkilerinin Belirlenmesi

Öz

Dış ortam çevre şartlarının ahşap malzeme üzerinde çeşitli etkilerde bulunarak ahşaba ait yapısını değiştirdiği bilinmektedir. Her ahşap türü farklı yapısal özelliklere sahip olması ile dış ortam şartlarına karşı farklı bir direnç özelliği sergilemektedir. Bu çalışmada, 60 günlük süre boyunca Bayburt ili dış ortam çevre koşullarının Sibirya çamı (Pinus sibirica) odunu üzerinde meydana getirdiği bazı yüzey değişikleri (renk, parlaklık ve beyazlık idneksi değerleri) araştırılmıştır. Elde edilen sonuçlara göre, bütün testler için varyans analizi sonuçlarının anlamlı olarak bulunduğu belirlenmiştir. Ayrıca yaşlandırma süresinin artması ile ışıklılık (L*) değerinin azaldığı, sarı (b*) renk tonu değeri, kroma (C*) ve ho değerinin arttığı görülmüştür. Toplam renk farklılıkları ise 30. günün sonunda ΔE*: 8.65 ve 60. günün sonunda ΔE*: 7.85 olarak bulunmuştur. Buna ek olarak, Δb*, ΔH*, ΔC* ve ΔE* değerleri yaşlandırma süresinin artması ile azalmıştır. Yapılan yaşlandırma uygulamasının Sibirya çamı odunu yüzeylerinde değişikliğe sebep verdiği görülmüştür.

Determination of Natural Weathering Effects on Whiteness Index, Color and Glossiness Values in Siberian Pine (Pinus sibirica) Wood

Öz

It is known that outdoor environmental conditions have various effects on wood material and change the structure of wood. Each type of wood has different structural properties and exhibits a different resistance to outdoor conditions. In this study, some surface changes (colour, glossiness and whiteness index values) on Siberian pine (Pinus sibirica) wood of Bayburt province outdoor environmental conditions were investigated during a 60-day period. According to the results obtained, it was determined that the analysis of variance results for all tests were found to be significant. It was also observed that the lightness (L*) value decreased, the yellow (b*) colour value, chroma (C*) and ho values increased with increasing weathering time. Total color differences were found to be ΔE*: 8.65 at the end of the 30th day and ΔE*: 7.85 at the end of the 60th day. In addition, Δb*, ΔH*, ΔC* and ΔE* values decreased with increasing weathering time. It was observed that the aging application caused changes in the surfaces of Siberian pine wood.
