Abstract

Viskoelastično toplotno zgoščen (VTC) les ima zaradi visoke gostote in s tem izboljšanih mehanskih lastnosti velik potencial pri razvoju visokokakovostnih lesnih proizvodov. Širšo uporabo omejuje med drugim tudi slaba odpornost na glive razkrojevalke. Termična modifikacija je eden od načinov, s katerim lahko izboljšamo odpornost lesa proti lesnim glivam. S kombinacijo zgostitve in termične modifikacije lesa smo dosegli sinergijske učinke in pridobili material, ki je ohranil pozitivne lastnosti obeh postopkov. Termično modificiran VTC les je bistveno bolj odporen proti glivam kot nezgoščen les ali kot nemodificiran VTC les.

Secondary title: Influence of thermal modification of densified wood on fungicidal properties
Secondary abstract: Viscoelastic thermal compressed (VTC) wood has due to its high density considerably better mechanical properties, and therefore, expresses a great potential for the development of the high quality wood products. The wider application is limited, among others, also because its weak resistance to the wood decay fungi. The thermal modification is one of the methods able to improve the resistance of wood against wood decay fungi. By applying the VTC compressions and the thermal modifications of wood the synergy effects were achieved, and material preserving the positive features of both procedures gained. The thermal modified VTC wood is significantly more resistant to fungi than the non-compressed wood or the non-modified VTC wood.
