Lastnosti železniških pragov, impregniranih z baker-etanolaminskimi pripravki, po štirih letih izpostavitve na prostem : diplomsko delo = Properties od railway sleepers, impregnated with copper-ethanolamine preservative solutions, after four years of outdoor exposure : B. Sc. thesisGoropečnik, LukaLes na prostem je izpostavljen biotskim in abiotskim dejavnikom razkroja. V naravi so ti procesi zaželeni, kadar pa les uporabljamo v gospodarske namene, jih želimo čim bolj upočasniti. Če les ni ... ustrezno vgrajen ali zaščiten, lahko zaradi delovanja gliv v kratkem času propade. Les se pogosto uporablja v infrastrukturne namene, kot so na primer železniški pragovi. Zaščita železniških pragov je ena najstarejših aplikacij zaščite lesa v praksi. V preteklosti so za zaščito železniških pragov uporabljali predvsem kreozotno olje. Zaradi okoljske neprimernosti bo kreozotno olje prej ali slej prepovedano, zato je treba razviti ustrezne alternative. Ena od alternativ so bakrovi pripravki. Ti se odlično obnesejo za zaščito lesa iglavcev, o zaščiti mehansko obremenjenega bukovega lesa pa ni podatkov. V diplomski nalogi smo določili razkrojenost, koncentracijo bakrovih učinkovin, osnovne mehanske lastnosti železniških pragov, impregniranih z baker-etanolaminskimi pripravki in potrdili, da na bukovih pragovih ni opaziti znakov razkroja, če so pragovi impregnirani s pripravkom višje koncentracije.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [L.
