Izboljšanje impregnabilnosti smrekovega lesa s predhodnim dolgotrajnim namakanjem [Elektronski vir] : magistrsko delo = Improving the impregnability of Norway spruce wood by prior long-term immersion : M. Sc. ThesisHočevar, Luka, 1996-Smrekovina je naravno slabo odporna drevesna vrsta s slabo impregnabilnostjo, ki smo jo želeli izboljšati z dolgotrajnim namakanjem lesa v vodi. Smrekov les smo posekali na Dolenjskem v okolici ... Mokronoga in ga takoj po poseku namakali 1, 2 in 4 tedne. Ko je bil les zračno suh, smo ga testirali. Ugotavljali smo, ali se z namakanjem lesu izboljša impregabilnost ter ali se mu spremenijo mehanske lastnosti in kemijska zgradba. Izvedli smo mehanske teste (tritočkovni upogib in tlačna trdnost), test odpornosti na glive razkrojevalke, meritev stičnega kota vode, test kratkotrajnega in dolgotrajnega navzema vode ter adsorpcijo vodne pare, test mokrega navzema biocidnega sredstva s postopkom vakuumiranja ter na elektronskem vrstičnem mikroskopu določili stopnjo aspiracije pikenjskih membran. Smrekovemu lesu se po 4 tednih namakanja v vodi povečata mokri navzem zaščitnega sredstva ter odpornost na glive razkrojevalke. Les ima tudi večjo tlačno trdnost ter manj aspiriranih pikenjskih membran. Upogibna trdnost se je lesu zmanjšala. Lesu se v primerjavi s kontrolnimi vzorci ne spremeni hidrofobnost. Z namakanjem smrekovine v vodi 4 tedne, lesu izboljšamo impregnabilnost, kar smo želeli doseči. Vendar se mu spremenijo tudi mehanske lastnosti, predvsem se poslabša upogibna trdnost in les ni nič bolj hidrofoben. Če želimo ugotoviti, ali se izboljša tudi hidrofobnost ter upogibna trdnost, bi bilo potrebno izvesti poskuse na lesu s še daljšim časom potapljanja v vodi.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [L.
