Abstract:Izpiranje aktivnih učinkovin iz impregniranega lesa je eden izmed najpomembnejših kriterijev za presojanje uporabnosti zaščitnih pripravkov za zaščito lesa na prostem. V te namene uporabljamo več različnih standardnih in nestandardnih postopkov: SIST EN 84, SIST EN V 1250-2 in priporočilo OEC D. V sklopu te raziskave smo med seboj primerjali izpiranje bakrovih in borovih spojin iz lesa, zaščitenega s pripravki: (a) vodno raztopino bakrovega sulfata, (b) bakeretanolaminskim komercialnim pripravkom Silvanolin, (c) vodno raztopino borove kisline in (d) kombinacijo borove kisline in vodne emulzije voska montana. Globinsko impregnirane vzorce smo izpirali in določili delež izpranega Cu in B. Največji delež biocidov smo izprali iz lesa zmetodo SIST EN 84, najmanj pa z metodo OEC D. Kakorkoli, z vsemi testiranimi metodami smo prišli do istega vrstnega reda pripravkov glede na delež izpranih aktivnih učinkovin iz lesa.

Title:Comparison of standard procedures for estimation of biocides leaching from impregnated wood
Abstract:Leaching of active ingredients from impregnated wood is one of the most frequently applied criteria for assessing the suitability of impregnated wood to be used in outdoor applications. For this purposes, several standard and nonstandard procedures are applied. Within the framework of this research, leaching of copper and boron compounds from wood, impregnated with four different wood preservatives, were compared: (a) aqueous solution of copper sulphate, (b) commercial copper-ethanolamine based solution Silvanolin, (c) aqueous solution of boric acid and, (d) combination of boric acid and montanic wax emulsion. Pressure impregnated specimens were afterwards leached according to the three different standards: SIST EN 84, SIST EN 1250 and OECD recommendation. The highest portion of leached biocides were determined according to the SIST EN 84 procedure, the lowest portion according to OECD recommendation. All three methods applied, however give us the same ranking of wood preservatives regarding the amount of emitted active ingredients.
