| Özet |
| Physical, chemical, biological and microscopic properties change in unprotected wooden material exposed to weathering conditions. Decay in weathering is a result of chemical change in the cell walls that caused by the activities of microorganisms and primarily starting with the decomposition of lignin. Besides, wood surfaces are ruined by some effects such as quickly wet and dry, daily and seasonal relative humidity changes, temperature changes, wind, atmospheric pollution, oxygen, and human activities. The aim of this study is to determine changes of surface properties of heat treated wood exposed to weathering. For this purpose, Calabrian pine and chestnut woods have been used. After the experimental samples have been cut, they were subjected to heat under atmospheric pressure at three different temperatures (130, 180 and 230 oC) and two different time levels (2 and 8 h). Then, heat treated samples have been exposed to accelerated weathering conditions at two different time levels (120 and 240 h) according to related standards. After ageing, the changes in wood surfaces were observed by scan electron microscope (SEM). Also, results have been compared with values of control samples belong to each group. |
