Utrjevanje različnih frakcij utekočinjenega lesa : diplomski projekt = Curing of various fractions of liquefied wood : B. Sc. thesisZakrajšek, Jure, 1988-Zaradi okoljevarstvenih zahtev potekajo različne raziskave v smeri iskanja in priprave okolju prijaznejših premazov za les, ki bi bili alternativa klasičnim pripravkom za površinsko obdelavo lesa. ... Tako bi za premaze lahko uporabljali tudi utekočinjen les, ki ga pridobivamo s termokemičnim postopkom (s solvolizo). Vendar je pomanjkljivost filmov iz utekočinjenega lesa v tem, da so temno rjave oz. črne barve, kar močno omejuje njihovo uporabnost. V diplomskem projektu smo skušali pripraviti svetlejši utekočinjen les s postopkom ultrafiltracije. Z že uveljavljenim postopkom utekočinjanja smo utekočinili lipov les in ga nato ultrafiltrirali. Ugotovili smo, da je barva ultrafiltriranega utekočinjenega lesa precej bolj svetla od izhodiščne utekočinjene zmesi. Naši rezultati tudi nakazujejo, da bi bilo možno svetlejši ultrafiltriran utekočinjen les, kljub njegovi različni sestavi od nefiltriranega lesa, utrditi. Za iskanje najprimernejših pogojev utrditve ultrafiltrirnega utekočinjenega lesa so potrebne nadaljnje raziskave, da bi lahko pripravili svetle filme s sprejemljivimi fizikalno kemijskimi in odpornostnimi lastnostmi.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
