Možnost uporabe propolisa za površinsko obdelavo lesa : diplomsko delo (univerzitetni študij) = Possibilities of use of propolis for wood finishing : graduation thesis (university studies)Budija, FrancPreučevali smo možnosti uporabe propolisa za površinsko obdelavo bukovega, javorjevega in smrekovega lesa. Pripravili smo 33,7 % raztopine propolisa v 96 % etanolu ali nitro razredčilu. Nato smo xza ... vsako formulacijo posebej določili nanose in čase utrjevanja po DIN 53150. Za nitro redčilo se je izkazalo, da kot topilo ne ustreza. Vzorce, obdelane z raztopinami propolisa smo sušili pri sobnih pogojih in v laboratorijskem sušilniku pri 40 °C. Za filme iz etanolne raztopine propolisa smo izvedli odpornostne teste proti različnim tekočinam, določili smo sijaj in izmerili prožnost utrjenega premaznega sistema ter kontaktne kote vode. Ugotovili smo, da so s propolisom obdelane površine hidrofobne. Odpornostne lastnosti so na splošno slabe, dobra odpornost se je izkazala le proti olju in medu, zato ima tak sistem zelo omejene možnosti za površinsko obdelavo lesa. Sušenje raztopin propolisa je dolgotrajno. Površinski sistem se ne osuši do končne stopnje utrditve (film ostane mehak). Z nihajno (FT - IR) spektroskopijo smo ugotovili, da na površini lesa poteče fizikalni način utrjevanja. Uporaba propolisa bi bila zanimiva v kombinaciji z raznimi naravnimi smolami, laki, olji in voski. Menimo, da bi bile potrebne dodatne raziskave, s katerimi bi izboljšali lastnosti premazov na osnovi propolisa.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [F.
