Odpornost izolacijskih pen na osnovi tanina iz skorje iglavcev proti glivam : diplomski projekt = Resistance of insulating foams based on tannin from the bark of conifers against fungi : B. Sc. thesisŽveplan, ErvinProučevali smo odpornost pen na osnovi tanina iz skorje iglavcev proti glivam. Pripravili smo 4 različne sestave taninskih pen. Iz utrjenih taninskih pen smo nažagali preizkušance in jim izmerili ... dimenzije ter maso. Nato smo preizkušance 3 dni izpirali z destilirano vodo in jih na koncu posušili na absolutno suho stanje (103 °C, 24 h). Preizkušancem smo ponovno izmerili dimenzije in jih stehtali ter izračunali gostoto pen pred in po izpiranju. Ugotovili smo, da se je masa preizkušancev po izpiranju razpolovila, volumen pa se je po osušitvi zmanjšal za tretjino. V petrijevkah smo pripravili gojišče za glive, jih cepili in po 1 tednu nanje položili preizkušance iz pen in lesa; ti so bili glivam izpostavljeni 8 tednov. Uporabili smo 1 glivo rjave trohnobe (navadna tramovka- Gloeophyllum trabeum) in 1 glivo bele trohnobe (bukov ostrigar-Pleurotus ostreatus). Po 8 tednih smo iz preizkušancev očistili micelij in jih stehtali. Preizkušance smo po tehtanju osušili na absolutno suho stanje in jih ponovno stehtali. Iz dobljenih podatkov pred in po izpostavitvi glivam smo izračunali izgubo mase. Ugotovili smo, da so pene na osnovi tanina iz skorje iglavcev odporne na lesne glive, saj je bila izguba mase v primerjavi z lesenimi preizkušanci precej manjša.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [E.
