Lastnosti z voski impregnirane termično modificirane smrekovine : magistrska naloga = Properties of wax impregnated thermally modified spruce : M. Sc. thesisZupančič, Klemen, 8. 3. 1989-Les je naravni material, ki se dandanes vse bolj uporablja v gradbene namene. Ker vse vrste lesa niso dovolj odporne, jih je treba primerno zaščititi. V naši raziskavi smo uporabili manj odporno ... smrekovino in jo zaščitili z nebiocidnimi sredstvi. Les smrekovine smo impregnirali s suspenzijo naravnega voska in ga termično modificirali. Termična modifikacija je potekala pri temperaturah 100 °C, 185 °C, 200 °C, 215 °C in 230 °C. Sledila je impregnacija z naravnim voskom, ki je bila izvedena po 2 postopkih (potapljanje in vakuumska tlačna impregnacija), pri 2 različnih koncentracijah (2,5 % in 5 %). Preučevali smo vpliv termične modifikacije, način impregnacije in koncentracijo suspenzije voska na navzem vodne pare, mehanske lastnosti in odpornost proti glivam. Izkazalo se je, da termična modifikacija v večji meri vpliva na izgubo mase vzorcev in s tem poslabšanje mehanskih lastnosti lesa, pozitivno pa vpliva na odpornost proti glivam. Pri določanju prodiranja vodne pare v les sta obe koncentraciji pokazali, da po obdelavi z voski ostaja površina difuzijsko odprta. Bolj kot sama koncentracija, pa je odločilen način impregnacije lesa, pri čemer se je v večji meri izkazala vakuumska tlačna impregnacijaType of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [K.
