Abstract
This research was aimed at determining the surface roughness and surface brightness properties of Scots pine (Pinus sylvestris L.) wood samples to which water-based varnishes were applied after thermo-mechanical densification and heat treatment. Samples; after densifying by compression in the radial direction at two different rates (20 and 40 %) and two different temperatures (110 and 150 °C), samples were subjected to 2 h of heat treatment at 190, 200, and 210 °C. Then, surface of the samples was varnished with one-component (OCW) and two-component (TCW) water-based varnishes. The changes occurring in surface roughness and surface brightness of the samples were determined according to the basis of TS 2495 EN ISO 3274, TS 6212 EN ISO 4288 and TS EN ISO 2813. According to results of the research, surface roughness decreased and surface brightness increased in densified samples. On the other hand, an increase in the heat treatment temperature led to an increase in surface roughness and a decrease in surface brightness. Also, regarding the effect of varnish type on both surface roughness and surface brightness, better results were obtained in the surface OCW applied compared to those TCW applied.
