Abstract
The study aimed to determine some surface parameters such as surface roughness and color changes of thermally modified Oriental beech (Fagus orientalis L.) wood samples after 750 hours of artificial weathering. The results of the study showed that artificial weathering led to an increase in surface roughness of Oriental beech wood. Thermal modification interval of 210 °C - 230 °C gave a smoother surface than unmodified samples after artificial weathering. Artificial weathering caused darker, reddish, and yellowish tone of unmodified and thermally modified Oriental beech wood. According to the study fi ndings, surface properties of thermally modified Oriental beech wood were better than those of unmodified Oriental beech.
Highlights
IntroductionWood has been preferred in the field of construction sector and furniture manufacture since ancient times, due to its natural beauty, thermal insulation, high strength, ease of use and processing (Su, 1997)
Duncan test with a 95 % confidence level of surface roughness and total color change test results were evaluated with a computerized statistical program
Thermal modification gave a smoother surface than unmodified Oriental beech after artificial weathering
Summary
Wood has been preferred in the field of construction sector and furniture manufacture since ancient times, due to its natural beauty, thermal insulation, high strength, ease of use and processing (Su, 1997). (Kiguchi and Evans, 1998). Wood is readily decomposed by environmental factors, including water, solar rays, bacteria, fungi and insects, fire, etc. This problem may be decreased by using chemical or thermal treatments. The harms of chemicals used in treatment to increase the durability of wood are discussed. The demand for treating wood with environmentally friendly substances is increasing
