Analiza dinamičnih mehanskih lastnosti lesa v postopku konvekcijskega komorskega sušenja : diplomsko delo = Analysis of the dynamic mechanical properties of wood during convective kiln drying : B. Sc. thesisHrovatič, PeterRaziskali smo kinetiko sušenja žaganega lesa invazivnih lesnih vrst, robinije, amerikanskega javorja in navadnega divjega kostanja. Preizkušance debelin 22 mm, 28 mm in 46 mm smo sušili v ... laboratorijskem sušilnem kanalu, pri temperaturi 40 °C in 60 °C. Dinamične mehanske lastnosti smo med sušenjem analizirali s frekvenčnim odzivom pri vzdolžnem in prečnem nihanju 490 mm dolgih preizkušancev. Intervalno smo gravimetrično določali še povprečno vlažnost in vlažnostni gradient, ter prečno krčenje lesa. Sušenje je potekalo hitreje pri višji temperaturi, debelina preizkušancev pa je na hitrost sušenja vplivala negativno. Najnižji modul elastičnosti, vzdolžni in upogibni, smo pri vseh lesnih vrstah in pogojih sušenja potrdili v svežem stanju. Pri sušenju, se je s padanjem vlažnosti lesa najprej začel povečevati vzdolžni modul elastičnosti. Spremembe so se pojavile že pred krčenjem lesa, pri povprečni vlažnosti nad točko nasičenja lesnih vlaken. Odziv je bil večji pri debelejših sortimentih, kjer je bil prisoten večji vlažnostni gradient. Upogibni modul elastičnosti je bil vselej nižji kot vzdolžni modul elastičnosti. Upogibni modul elastičnosti se pri vlažnosti lesa nad točko nasičenosti značilno ne spreminja, prične pa naraščati s padanjem vlažnosti lesa v higroskopskem območju.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [P.
