Abstract:The long-term durability of varnished wooden surfaces used in either indoors or outdoors environments depends on the resistance of varnish layers on these surfaces against potential physical, mechanical and chemical effects to which they may be exposed. In this study, "Nanolacke ultraviolet varnish", developed by a Turkish dying and varnish industry company and widely accepted as a 21 st century technology has been compared to other conventional varnish systems widely used in the industry in terms of dry film resistance properties. In this study, cellulosic, polyurethane, polyester, synthetic and Nanolacke ultraviolet varnish have been applied on beech (Fagus orientalis L.) and oak (Quercus robur L.) wood samples which had been prepared according to the industry standards. Then, the hardness and adhesion resistance of these layers have been determined according to ASTM D 4366 and ASTM D 3359-2 standards, respectively.

“…After the varnishing process, the layer hardness of the samples was determined. According to this; the highest in terms of hardness value, wood type, impregnation material and varnish type interaction; sessile oak+borax+acrylic varnish, lowest; Obtained in oak+borax+synthetic varnish [37]. The hardness value, water-based varnish + nano silver interaction, was found to be 8% lower in Oriental beech, 12% higher in Oak compared to the control samples and it did not show any effect in Scots pine.…”

Bu çalışmada, bazı antibakteriyel nano malzeme katkılı verniklerin ahşap malzemede katman sertliğine etkisi araştırılmıştır. Sarıçam (Pinus sylvestris L), Doğu kayını (Fagus orientalis Lipsky), sapsız meşeden (Quercus petraea Liebl.) hazırlanan örneklere, %0,1, %0,3 nano bor (NaB) ve nano gümüş (NaAg) ilave edilmiş su bazlı ve sentetik vernik ile ASTM D-3023’e göre verniklenmiştir. Vernikleme işleminden sonra örneklerin yüzey sertliği (salınım) ASTM D 4366-95’e uyularak yapılmıştır. Sonuç olarak; yüzey sertlik değeri malzeme çeşidi bakımından en yüksek, Doğu kayını, sentetik vernik, nano bor ve %0,1’de, en düşük sarıçam, su bazlı vernik, nano gümüş ve %0,3’de tespit edilmiştir. Çoklu etkileşimde en yüksek Doğu kayını+sentetik vernik+%0,1 nano bor (28,00)’de, en düşük sarıçam+sentetik vernik+%0,3 nano gümüş (11,20)’ de elde edilmiştir. Kontrol örneklerine göre, nano malzemeler verniklerin yüzey sertliğine azaltıcı etki gösterdiği tespit edilmiştir. Bu durum, vernik sertliğinin önemli olduğu uygulama alanlarında dikkate alınması avantaj sağlayabilir. Antibakteriyel özelliği yüksek olan nano malzemelerin ahşap üst yüzey işlemlerinde kullanılması ile yeni fikirler ortaya çıkacak ve aşınma riski yüksek olan kullanım alanlarında avantaj sağlayacaktır.

“…Previous studies have explained that the wood hardness increased after impregnation. Boric acid and borax increased the hardness of varnished wood surface (Ors et al 2007). Malik and Ozarska (2019) reported that the density and hardness of white jabon wood ( Anthocephallus cadamba ) increased after impregnation with polymerized merbau extractives.…”

This research was conducted to detect changes in the mechanical properties of samama wood (Anthocephalus macrophyllus) after impregnation with boron, castor bean oil, and heat treatment. Samama wood has low durability so samples were impregnated with boric acid followed by impregnation with castor oil in order to achieve some fixation of the boric acid. After impregnation, heat treatments were applied for four hours at 80°C and 160°C. Results showed that the modulus of elasticity (MOE), modulus of rupture (MOR) and hardness of samama wood generally increased after the treatments. Compared with the control, the maximum differences in MOE and MOR were 19.9% and 26.7%, respectively. Castor oil treatment also increased the density and hydrophobicity of the samama wood.
