Summary: | 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.
Cilj rada bio je proučiti neka površinska svojstva uzoraka toplinski modificirane bukovine (Fagus orientalis L.) poput hrapavosti površine i promjena boje nakon 750 sati umjetnog izlaganja uzoraka vremenskim utjecajima. Rezultati su pokazali da umjetno izlaganje vremenskim utjecajima uzrokuje povećanje hrapavosti površine uzoraka bukovine. Toplinskom modifikacijom pri temperaturi od 210 – 230 °C postiže se glađa površina od one koju imaju nemodificirani uzorci nakon umjetnog izlaganja vremenskim utjecajima. Umjetno izlaganje vremenskim utjecajima uzrokuje tamnjenje uzoraka te povećanje udjela crvenoga i žutog tona na nemodificiranoj i toplinski modificiranoj bukovini. Dobiveni rezultati pokazuju da su svojstva površine toplinski modificirane bukovine bolja od površinskih svojstava nemodificirane bukovine. |
