Aim of the study: This study examines the overall color change values from applying water-based, polyurethane, and acrylic varnishes on newly prepared and naturally aged wood materials. Materials and methods: The Turkish woodworking industry commonly selects oak (Quercus petrea L.), chestnut (Castanea sativa M.), and scotch pine (Pinus sylvestris L.) as the preferred wood type for preparing test samples. A total of 360 test samples are prepared for the experiments. The color difference (ΔE*) between two colors is measured using a Minolta CR-231 color measurement device, following the principles outlined in ASTM-D 2244. Main results: On the C.I.E. Lab* color plane, a higher ΔE* indicates a more significant difference between the compared colors. Among the wood type, oak exhibited the highest color change (ΔE*), while chestnut displayed the lowest. Fresh wood materials showed higher color change values (ΔE*) than naturally aged wood materials. The radial section direction also is showed higher color change values (ΔE*) than the tangential section direction. Research highlights: Regarding varnish type, acrylic varnish indicated a minor color change, followed by polyurethane and water-based varnishes, respectively. Acrylic varnish is recommended for studies with minimal color change and for preserving the wood material's natural color.

This research was carried out to find out the impact the mechanical densifying process has on wood material on the varnish adhesion resistance to surface. To this end, the experiment samples acquired from black pine (Pinus nigra) and Uludag Fir (Abies bornmulleriana Mattf) were subjected to densification in a hydraulic press at 140°C and a rate of 25% and 50% with a direction of radial. Following the process of densification, the sanded and unsanded samples were varnished with cellulosic and polyurethane varnishes, afterwards the surface adhesion resistance of the varnishes was determined. Regarding the three-way interaction between densification ratio, surface treatment and wood type, the highest surface adhesion resistance of the varnish layer was found in black pine + unsanded surface + 25% densification (1.98), and the lowest was in Uludag Fir + unsanded surface + 50% densification (0.99). Concerning the triple interaction of varnish type, concentration ratio and surface treatment, the highest surface adhesion resistance of the varnish layer was found in the polyurethane varnish + non-densified control group + sanded surface (2.23), and the lowest was in cellulosic varnish + non-densified control group + sanded surface (1.02). Approximate values were obtained for the densification process. It can be stated that the densification process creates high adhesion values for the polyurethane varnish in the black pine wood type. The sanding process has an intensifier effect on these values, and the products which were obtained from the polyurethane varnished samples do not require sanding. Considering these situations can provide significant advantages in projects with wood materials subjected to the densification process.

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.
