Bakır esaslı kimyasal (Korasit KS) ile emprenye edilen ağaç malzemenin doğal yaşlandırma sonrası üst yüzey özellikleri

Öz

Bu çalışmada, su bazlı ve bakır içerikli bir emprenye maddesi olan Korasit KS ile emprenye edilen Doğu kayını (Fagus Orientalis L.) odununun 3 aylık doğal yaşlandırma sonrası yüzey özellikleri incelenmiştir. Emprenye malzemesi ağaç malzemeye ASTM D 1413-07 (ASTM 2007) standardına göre %3 ve %6 konsantrasyon seviyelerinde nüfuz edilmiştir. Sonuçlara göre tüm numunelerin L* değerleri 3 aylık doğal yaşlandırmadan sonra azalmıştır. Emprenye edilen örnekler, kontrol numunelerinden daha iyi renk stabilitesi sağlamıştır. Ayrıca emprenye işleminde konsantrasyon miktarı arttıkça bu stabilitede artmıştır. Doğal yaşlandırma sonrası tüm numunelerin parlaklığı azalırken, bu azalma kontrol numunelerinde daha fazla gerçekleşmiştir. Yüzey pürüzlülüğü test sonuçlarına göre tüm numunelerin Ra, Rz ve Rq değerleri doğal yaşlandırma sonrası artmıştır. Bu artış emprenye edilen örneklerde daha fazla olmuştur.

Surface properties of wood material impregnated with copper-based chemical (Korasit KS) after natural weathering

Öz

In this work, the surface characteristics of Oriental beech (Fagus orientalis L.) wood impregnated with Korasit KS, a water-based and copper-containing impregnation substance, were examined after three months of natural weathering. The impregnation material was penetrated into the wood material at 3% and 6% concentration levels according to the ASTM D 1413-07 (ASTM 2007) standard. According to the results obtained, the L* values of all samples decreased after natural weathering. Furthermore, impregnated samples provided better color stability than control samples. Moreover, this stability increased as the concentration amount increased in the impregnation process. While the gloss of all samples decreased after natural weathering, this decrease was more in control samples. According to the surface roughness test results, Ra, Rz and Rq values of all samples increased after natural weathering. This increase was more in the impregnated samples.
