Resumen

BAYSAL, Ergun; KART, Saban; TOKER, Hilmi  y  DEGIRMENTEPE, Selim. Some Physical characteristics of thermally modified oriental- beech wood. Maderas, Cienc. tecnol. [online]. 2014, vol.16, n.3, pp.291-298.  Epub 13-Jun-2014. ISSN 0718-221X.

Heat treatment of Oriental-beech (Fagus orientalis) wood was carried out by hot air in an oven for 2, 4, and 8 h at 140, 170, and 200°C. After heat treatment, some physical characteristics such as surface roughness, color, glossiness, and mass loss of Oriental-beech wood specimens were measured. Our results showed that heat treatment caused decrease in surface roughness, glossiness, and mass loss values of Oriental-beech (Fagus orientalis) wood specimens. The decrease in lightness at all temperatures indicates that the specimens become darker with the treatment time. While, a* coordinate (red component) decreased as temperature increased, b* coordinate (yellow component) initially increased at 140°C and then decreased at 170°C and 200°C.

Palabras clave : Heat treatment; oriental-beech; surface roughness; glossiness; color; mass loss.
