Uvajanje kontinuiranega spremljanja vlažnosti impregniranega lesa v zunanjih pogojih : diplomsko delo - visokošolski strokovni študij = Introduction of continuous moisture content monitoring of impregnated wood in outdoor conditions : graduation thesis - higher professional studiesPosavec, RokLes je organska snov. Ena izmed lastnosti lesa je sposobnost sprejemanja in oddajanja vlažnosti. Vlažnost lesa je pomembna z več vidikov. Eden najpomembnejših je, da je suh les varen pred delovanjem ... večine lesnih gliv. Vlažnost lesa zato pogosto spremljamo na ogroženih lesnih konstrukcijah. Lesu vlažnost določamo na različnih stopnjah obdelave. Simulirali smo 2 primera uporabe lesa v 3. razredu uporabe. Les smo prepojili z različnimi hidrofobnimi sistemi in spremljali upornost lesa. Upornost lesa in vlažnost lesa sta v določenem območju tesno povezana. Spremljali smo vlažnost hrastovih, kostanjevih, smrekovih, bukovih, macesnovih in borovih (jedrovina) vzorcev, ki so bili impregnirani z različnimi hidrofobnimi pripravki (tungovo olje, parafinsko olje, silikonska emulzija, rustikal olje, polietilenski vosek, baker- etanolaminski pripravek). Vzorci so bili 8 mesecev izpostavljeni v zunanjih pogojih v ležečem in visečem položaju. Uporovni merilnik je vsak dan ob polnoči izmeril upornost lesa v danem trenutku. Med vsemi testiranimi vzorci se je v obdobju izpostavitve v zunanjih pogojih najbolj obneslo tungovo olje na vseh impregniranih vzorcih, najslabše pa baker - etanolaminski pripravek na smrekovini in bukovini. Podnebje je v najmanjši meri vplivalo na vlažnost lesa borove jedrovine, najvišje vlažnosti pa smo določili pri neimpregnirani smrekovini.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [R.
