Termična modifikacija lesa smrek lubadark : diplomsko delo = Thermal modification of bark beetle damaged spruce wood : B. Sc. thesisKončan, ŽigaZaradi velikih količin manj vrednega pomodrelega lesa,nas zanima, ali lahko takemu lesu dvignemo dodano vrednost s postopkom termične modifikacije. Pomodrele in kontrolne vzorce smrekovine smo ... modificirali pri dveh temperaturah in na njih izvedli več testov. Zanimala nas je izguba mase po modifikaciji, sprememba barve, tlačna trdnost, upogibna trdnost, stični kot, kratkotrajni in dolgotrajni navzem tekoče vode ter sorpcijske lastnosti. Testi so pokazali, da ima modificiran pomodrel les malo slabše mehanske lastnosti kot nepomodrel. Vse ostale, za termično modificiran les bolj pomembne lastnosti, pa so se izboljšale. Stični kot se je pomodrelim vzorcem po termični modifikaciji znatno povečal, na kontrolne vzorce pa ni imel bistvenega vpliva. Na kratkotrajni in dolgotrajni navzem vode je imela termična modifikacija velik vpliv. Navzem pomodrelih in kontrolnih vzorcev se je zmanjšal na primerljivo vrednost. Termična modifikacija je izboljšala tudi sorpcijske lastnosti; ravnovesna vlažnost vseh vzorcev je padla, povečala pa se je tudi sposobnost oddajanja vlage oz. sušenja. Celotna serija poskusov nam je pokazala, da lahko s termično modifikacijo pomodrel les znatno izboljšamo in mu tako dvignemo dodano vrednost.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [Ž.
