| Özet |
| Physical, chemical, biological and microscopic properties change in unprotected wooden material that is exposed to weathering conditions and so its structural and some characteristic properties such as colour, gloss and hardness are ruined. The aim of this study is to determine changing of colour, gloss and hardness values of heat treated wood exposed to weathering. For this purpose, Anatolian black pine, calabrian pine, sessile oak and chestnut woods have been used. The experimental samples were subjected to heat under atmospheric pressure at three different temperatures (130, 180 and 2300C) and two different time levels (2 and 8 h). Then, heat treated samples have been exposed to accelerated weathering conditions to two different time levels (120 and 240 h) according to related standards. After the accelerated weathering procedure, changes in the colour, gloss and hardness of the samples have been determined according to related standards. The hardness values of heat-treated wood increased at low heating temperature and time. Aged wood hardness and gloss decreased, compared to the control specimens. Also, results have been compared with values of control samples belonging to each group. |
