Vpliv relativne zračne vlažnosti in anoksičnih razmer na vezavo baker-etanolaminskih pripravkov v smrekovino : diplomsko delo - visokošolski strokovni študij = Influence of relative air humidity and anoxic conditions on fixation of copper-ethanolamine wood preservatives : graduation thesis - higher professional studiesBiškup, Jure, 1982-Med najpomembnejša zaščitna sredstva za impregnacijo lesa v 3. in 4. razredu izpostavitve spadajo baker-etanolaminski pripravki. Fiksacija teh pripravkov je v primerjavi s klasičnimi hitrejša in je ... končana v 2 do 24 urah po impregnaciji. Po določenem času se vezava teh pripravkov zopet poslabša. Ugotavljali smo kako različni postopki kondicioniranja vplivajo na vezavo baker-etanolaminskih pripravkov v les. Smrekove vzorce smo impregnirali s 3 koncentracijami zaščitnega pripravka Silvanolin (CCu = 0,1 %, 0,25 % in 0,5 %). Po impregnaciji smo vzorce kondicionirali 10 dni pri različnih pogojih (anoksični pogoji, suha klima, vlažna klima ...), zatem pa smo jih izprali v skladu s standardom SIST EN 1250. Iz vzorcev, impregniranih z zaščitnim pripravkom višje koncentracije, se je v povprečju izpral manjši delež Cu učinkovin kot pri vzorcih impregniranih z nižjo koncentracijo. Najvišji delež (2,8 %) izpranega Cu iz vzorcev smo opazili pri sušenju na temperaturi 50 °C in srednji koncentraciji (CCu = 0,25 %). Najmanj Cu (1,0 %) pa se je izpralo iz pripravkov višje koncentracije (CCu = 0,5 %) pri temperaturi 25 °C. V večini primerov je bila vezava baker-etanolaminskih pripravkov pri višji relativni zračni vlažnosti boljša kot pri vzorcih, sušenih v suhi atmosferi. Anoksične razmere so pozitivno vplivale na vezavo Cu v les.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
