20.500.12556/RUL-506 Odpornost lesa, premazanega z vodnimi emulzijami voskov, proti glivam modrivkam in plesnim diplomsko delo - univerzitetni študij Resistance of wood brushed with wax water emulsions against blue stain fungi graduation thesis - university studies Z zaščito lesa želimo čimbolj podaljšati življenjsko dobo lesa. V današnjem času so še posebno pomembne nebiocidne zaščite; ena od možnosti je zaščita z vodnimi emulzijami voskov. Trajnost in izgled lesa močno poslabšajo glive modrivke in plesni. Da bi ugotovili učinkovitost vodnih emulzij voskov proti glivam modrivkam in plesnim, smo z vodnimi emulzijami montanskega polietilenskega ter oksidiranega polietilenskega voska premazali vzorce borove beljave in preverili delovanje v skladu s standardom SIST EN 152-1. V posameznih primerih smo vodnim emulzijam voskov dodali še borovo kislino. Ugotovili smo, da vzorci, zaščiteni z vodnimi emulzijami voskov, niso bistveno zaščitili lesa pred modrenjem in plesnenjem. Z dodajanjem borovih učinkovin vodnim emulzijam smo odpornost zaščitenega lesa proti glivam modrivkam močno izboljšali. To prolong service life of wood its protection is applied. Importance of non-biocidal solutions used to protect wood is increasing nowadays. One of the options for such protection is utilization of wax emulsions. Among various factors influencing service life and aesthetic aspects of wood are blue stain fungi and moulds. To elucidate influence of various wax emulsions on blue stains and moulds, pine sapwood specimens were brushed with various emulsions of montan, polyethylene and oxidized polyethylene waxes. Experiment was performed according to EN 152-1 procedure. To achieve a better effect, aqueous emulsions of waxes were supplemented with boric acid. The results showed that wax treatment did not improve resistance of pine wood against staining fungi. However, addition of boron to wax emulsions significantly decreases staining. les zaščita lesa vodne emulzije voskov montanski vosek polietilenski vosek glive modrivke wood wood preservation water emulsions montan wax polyethylene wax blue stain fungi true false false [J.
