| Abstract [eng] |
Master‘s thesis aims to investigate the influence of hydrothermal and thermal treatment in oil on construction wood's physical, mechanical, and UV resistance properties. The aim of the work is implemented through the 5 work tasks, which include literature analysis, heat treatment of samples by changing the temperature regime and agent, and research on physical, mechanical and UV resistance properties. The literature analysis discusses wood's structure, chemical composition, physical and mechanical properties, the effects of thermal, hydrothermal, and thermal oil treatment on wood, and the possibilities of using treated wood. The experimental part describes the research equipment and the research process. During the study, wood samples were hydrothermally treated at different temperature regimes in an autoclave, and thermally in oil under open conditions. The following altered wood properties were observed: dimensional stability, physical properties, mechanical properties, resistance to biological factors, and changes in surface structure. |
