20.500.12556/RUL-158701 Lastnosti z bio-premazi obdelanih površin lesa navadnega oreha magistrsko delo Characteristics of Persian walnut wood surfaces finished with bio-coatings M. Sc. thesis Trend površinske obdelave je vse bolj usmerjen v okolju prijazne premaze, sem pa spadajo tudi naravna olja in voski. Izbrali smo 11 premaznih sredstev na osnovi lanenega, tungovega, konopljinega, sončničnega, sojinega in osatovega olja, ter čebeljega voska. Zaradi velikega povpraševanja po temnih lesovih smo za podlago uporabili les navadnega oreha (Juglans regia L.). Kakovost posameznega premaznega sistema smo določili s standardiziranimi metodami: odpornost površine proti hladnim tekočinam, odpornost površine proti suhi toploti, sijaj, stopnjo utrjenosti, ter s pomočjo anketiranja vonj. Raziskava je pokazala dobro odpornost sistemov proti suhi toploti, nekaterih slabšo nekaterih boljšo odpornosti proti hladnim tekočinam, nekoliko daljše čase sušenja premazov brez sikativa, svilnat lesk površine, poudarjeno barvo lesa, ter da so brez izrazito motečega vonja. Vsi konvencionalni pripravki in eno naravno olje so zaradi hitrega sušenja primerni za industrijo. Glede na to, da so olja in voski obnovljivi, so primerni za vse površine, če je uporabnik le pripravljen lesene površine redno čistiti, vzdrževati ter po potrebi obnavljati. The trend of surface treatment has been increasingly oriented towards environment friendly wood coatings including natural oils and waxes. 11 wood coatings based on linseed, tung tree, hemp, sunflower, soybean, safflower oil and beeswax were chosen. Because of high demands for dark wood, we selected Persian walnut (Juglans regia L.) for the basis. The quality of an individual coating system was assessed according to standard methods: resistance to selected liquids, resistance to dry heat, gloss, degree of hardness and odour based on a survey. The research showed good resistance to dry heat, differences in resistance to cold liquids, somewhat longer drying time of coatings without a siccative, silky gloss of the surface, highlighted wood colour and no disturbing or bad odour. Because of short drying time, all conventional products chosen, plus one natural oil, are suitable for industry. Since waxes and oils are renewable, they are suitable for all surfaces if the user is prepared to regularly clean, maintain and, if necessary, restore wooden surfaces. površinska obdelava lesa bio-premazi naravni premazi voski surface treatment of wood bio-coatings natural coatings oils waxes true false false J.
