Vpliv impregnacije s sivo glino na fungicidne lastnosti lesa : diplomsko delo - visokošolski strokovni študij = The effect of impregnation with grey clay on the fungicidal properties of wood : graduation thesis - higher professional studiesKrek, Sebastjan, lesarstvo, 1978-Smreka (Picea abies) in bukev (Fagus sylvatica) predstavljata večino lesne mase v slovenskih gozdovih in sta najpomembnejši drevesni vrsti pri nas. Žal spadata med manj odporne lesne vrste. Ob ... nepravilni konstrukciji ter vgradnji se problem trajnosti izdelka še poveča. Problem se rešuje s kemično zaščito lesa, ta je problematična zaradi negativnega vpliva na človeka in okolje. Danes je zaželeno, da les zaščitimo s pravilno konstrukcijo in vgradnjo izdelka. Samo zaščito lesa pa skušamo zagotoviti z naravnimi zaščitnimi sredstvi kot sta čebelji vosek in razna naravna olja. V diplomski nalogi smo preučili delovanje sive gline kot impregnacijskega sredstva za zaščito proti lesnim glivam. Glino Poljanski sadjarji uporabljajo pri obrezovanju sadnega drevja. Vzorce smo v vakuumski komori impregnirali s tremi različnimi suspenzijami sive gline in destilirane vode. Impregnirane in kontrolne vzorce smo izpostavili lesnim glivam. Vzorce smreke smo izpostavili navadni tramovki (Gloeophyllum trabeum), vzorce bukve pisani ploskocevki (Trametes versicolor) in pahljačici (Schizophyllum commune) ter vzorce hrasta hrastovi labirintnici (Daedalea quercina), v skladu s standardom EN 113:2004. Po 16 tednih razkroja smo s primerjavo izgube mase med impregniranimi in kontrolnimi vzorci ugotovili, da suspenzija sive gline ne zavira razkroja lesa, ki je bil izpostavljen miceliju različnih lesnih gliv, saj je bila izguba mase v vseh primerih zelo podobna ali večja od kontrolnih. Tudi statistična analiza ni pokazala večjih razlik. Ugotovili smo, da različne suspenzije sive gline ne vplivajo na fungicidne lastnosti lesa.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [S.
