Özet:

 Aim of study: It is an investigation of the effects of bleaching processes on the color change in the wood of tree species. Tree species Eastern Beech Fagus Orientalis Lipsky. and Eastern Black Sea Fir Abies Nordmanniana subsp. were used in the study. Sodium hydroxide-hydrogen peroxide, oxalic acid, peracetic acid diluted 13, peracetic acid diluted 16 were used as bleaching agents. Trial samples were prepared in accordance with standards and color change measurements were made. Area of study: Surface treatments on wooden materials Material and methods: In the study, two wood species and one varnish type were used; Color changes were tested by applying various bleaches to the wooden material by rubbing method. Main results: As a result of the study, differences were observed in all cross-section shapes in beech wood bleaching measurements with 16 diluted peracetic acid, and differences were observed in cross-section shapes in fir wood bleaching measurements. The best bleaching of fir wood was achieved with peracetic acid. Main results: As a result of the study, differences were observed in all cross-section shapes in the beech wood bleaching measurements with 16 diluted peracetic acid, and in the cross-section shapes in the fir tree bleaching measurements. The best bleaching of fir wood was achieved with peracetic acid. Highlights: The bleaching process allows the wooden material to easily acquire a homogeneous color. Since the cell arrangements are different in different cross-sectional shapes, the bleaching rates are different from each other. While there is not much difference in the color changes in the wood material when bleached with oxalic acid, the samples are bleached as a result of bleaching with sodium hydroxide-hydrogen peroxide and peracetic acid. Significant changes have occurred in color changes. The reason for this difference is due to the different degrees of corrosion of bleaching agents.

 Çalışmanın amacı: Ağartma işlemlerinin ağaç türlerinin odunlarında renk değişimine etkilerinin araştırılmasıdır. Çalışmada ağaç türleri Doğu Kayını Fagus Orientalis Lipsky., Doğu Karadeniz Göknarı Abies Nordmanniana subsp. kullanılmıştır. Ağartma maddesi olarak sodyum hidroksit-hidrojen peroksit, oksalik asit, perasetik asit 13 seyreltilmiş, perasetik asit 16 seyreltilmiş ağartma maddesi olarak kullanılmıştır. Deneme numuneleri standartlara uygun olarak hazırlanmış ve renk değişimi ölçümleri yapılmıştır. Çalışma alanı: Ahşap malzemede üst yüzey işlemleri Materyal ve yöntem: Çalışmada iki ağaç türü ve bir vernik türü kullanılarak; ahşap malzemenin üzerine sürme yöntemi ile çeşitli ağartıcılar uygulanarak renk değişimleri test edilmiştir. Temel sonuçlar: Çalışma sonucunda 16 oranında seyreltilmiş perasetik asit kayın ağacı ağartma ölçümlerinde tüm kesit şekillerinde, göknar ağacı ağartma ölçümlerinde ise kesit şekillerinde farklılıklar gözlenmiştir. Göknar odununda en iyi ağartma perasetik asit ile elde edilmiştir. Araştırma vurguları: Ağartma işlemi, ahşap malzemenin kolaylıkla homojen bir renk almasını sağlar.Farklı kesit şekillerinde hücre dizilişileri farklı olduğundan dolayı ağartma oranları birbirinden farklıdır.Oksalik asit ile yapılan ağartmada ağaç malzemede renk değişimlerinde pek farklılık olmazken, sodyum hidroksit-hidrojen peroksit,perasetik asit ile ağartma sonucu numunelerin renk değişimlerinde önemli değişiklikler meydana gelmiştir.Bu farklılığın sebebi ağartma maddelerinin aşındırma derecelerinin farklı olmasından kaynaklanır.
