20.500.12556/RUL-134771 Uporaba naravnih olj za površinsko zaščito lesa navadne bukve Usage of natural oils for surface protection of common beech wood Za površinsko zaščito lesa navadne bukovine (Fagus sylvatica L.) smo uporabili različna naravna olja. Lastnosti premazanih površin smo proučili po različnih standardnih postopkih. Proučevali smo čas utrjevanja, spremembe barve in sijaja, navzem olj v les in navzem vode v oljen les, z meritvami navideznih kontaktnih kotov kapljic vode pa smo ocenili vodoodbojnost oljenega lesa. Rezultati standardnih preskusov odpornosti so pokazali, da imajo med olji, uporabljenimi v tej raziskavi, tungovo, komercialno olje decking in laneno olje najboljše vodoodbojne in zaščitne lastnosti. Slabše odpornostne lastnosti so bile ugotovljene pri površinah, premazanih z orehovim, konopljinim in kokosovim oljem Different natural drying oils were used for surface finishing of common beech wood (Fagus sylvatica L.). Surface performances and properties of the oiled surfaces were investigated according to the standard tests. Drying time, colour and gloss changes, uptake of oils into wood and uptake of liquid water into oiled wood, were determined, and the wettability of oiled wood surfaces was investigated by determination of the apparent contact angles of water. The results of the standard resistance tests showed that tung oil, the commercial decking and linseed oil had the best water repellent and protective properties. Worse properties were determined for those surfaces finished with walnut, hemp and coconut oils bukev Fagus sylvatica naravna sušeča olja lastnosti tenziometer omočljivost beech natural drying oils properties tensiometer wetability true false true Slovenski jezik Angleški jezik Članek v reviji 2022-02-01 08:42:18 2022-02-01 08:42:23 2024-04-11 13:02:04 0000-00-00 00:00:00 2017 0 0 Str. 37-46 št. 2 Letn. 66 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*829.1:176.1 Fagus sylvatica 0024-1067 2847369 RAZ_Zigon_Jure_2017.pdf RAZ_Zigon_Jure_2017.pdf 1 D430466D75FA3507C0FA6D4948FEF523 9ba949ef3fde7489ee2c5038113123730febbd02ce2a7b6ef820c43379d5c80d bee5ae80-8332-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153401 https://journals.uni-lj.si/les-wood/article/view/12193 0 47a54156-8332-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153400 Biotehniška fakulteta Les 0 0 0
