Effects of the termal and pressurised thermal modification treatments on chemical properties of the poplar woods
Abstract
In this study, it was planned to extend physical life of poplar wood (Populus usbekistanica), less natural durability and fast-growing tree species, with eco-friendly thermal treatment method. For this reason, poplar wood test samples were subjected to thermal and thermal-pressure modifications. The effects of the thermally modificated and thermally compressed on chemical properties of the poplar woods are investigated. The results indicated that, due to the applied 160oC above temperatures caused degradation in hemicellulose content, holocellulose (cellulose + hemicelluloses) content of the samples was decreased. At the same time, there were no remarkable changes in holocellulose content of the heat-compressed poplar wood compared with the control samples. Since the extractive substances are not taken into account, it was seen obviously that as temperature increases, the lignin content of the poplar samples also increased. As a result of heat-treated and heat-compressed modifications, it was observed that the heat treatment process below 160oC has no degradation on the chemical properties of poplar woods; however, degradation of the chemical properties was occurred, when the poplar woods were exposed above 160oC. Finally, it was seen that holocellulose content decreases as the duration of the treatment increases.
