Vpliv pufrov na odpornost z bakrovimi pripravki zaščitenega lesa pred trohnenjem : diplomsko delo - univerzitetni študij = Influence of buffering solutions on durability of copper treated wood against decay : graduation thesis - university studiesVidemšek, JernejaTrajnost lesa je odvisna od njegove naravne odpornosti, konstrukcijskih rešitev vgradnje in ne nazadnje uporabljene kemične zaščite. Za zaščito se še posebej pogosto uporabljajo bakrovi pripravki. V ... praksi se je izkazalo, da je učinkovitost teh pripravkov včasih nezadostna. Zato smo želeli ugotoviti ali lahko s spremembo vrednosti pH impregniranega lesa, upočasnimo trohnenje lesa, zaščitenega z bakrovimi pripravki. Poizkus smo izvedli na beljavi smrekovih vzorcev z nestandardno mini blok metodo. Uporabili smo glive: Antrodia vaillantii, Gloeophyllum trabeum, Hypoxylon fragiforme, Serpula lacrymans. Vzorce smo najprej vakuumsko impregnirali z 2 različnima raztopinama (CC in CuE) različnih koncentracij (cCu = 0,1 % in cCu = 0,25 %) ter jih nato prepojili s pufri: pH 5, pH 7, pH 9 in H2O. Rezultati so pokazali, da lahko učinkovito upočasnimo razkrojne procese, ki jih povzroča na baker tolerantna gliva Antrodia vaillantii, z višanjem vrednosti pH, saj je v bazičnem okolju bistveno manj razkraja kot v kislem. Tudi glivama Hypoxylon fragiforme in Serpula lacrymans ne ustrezajo bazične pH vrednosti lesa. Po drugi strani pa visoka pH vrednost lesa ustreza glivi Gloeophyllum trabeum, ki močno razkraja z bakrovimi pripravki zaščiteni les, naknadno prepojen z bazičnimi pufri.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
