Özet

The effect of the outdoor exposure in the Uzungol and Hdrnebi plateaus for 15 months on oriental spruce (Picea orientalis L.) wood is examined in this paper. A number of oriental spruce wood samples with eight different protection processes applied to them are subjected to weathering conditions. Heat treatment and impregnation with micronized copper quaternary (MCQ) and ultraviolet (UV) absorbing acrylic resin (UVA-acrylic) as a wood finish are used. The obtained changes in the color and roughness values, chemical changes, and visual macroscopic changes to the wood samples with and without protection, subjected to natural outdoor tests, are compared. It is revealed that the application of acrylic resin containing UV absorber on oriental spruce after heat treatment increases the resistance of the wood samples to weathering conditions in visual, physical, and chemical terms. In addition, heat treatment is determined to protect oriental spruce without wood finishing.
