20.500.12556/DiRROS-7633 Impregnabilnost in izpirljivost bakrovih zaščitnih pripravkov v odvisnosti od anatomske smeri lesa Impregnability and leachability of copper based preservatives with regard to anatomical plane of wood Zaradi omejitev uporabe klasičnih baker/kromovih pripravkov, industrija išče alternative za zaščito lesa v stiku z zemljo. Za impregnacijo takšnega lesa moramo uporabiti fungicide, ki se iz lesa ne izpirajo. Učinkovitost vezave v les določamo s standardno metodo, z majhnimi vzorci, kjer je delež aksialnih površin večji kot v praksi. Namen prispevka je ugotoviti, kakšno je izpiranje bakrovih učinkovin iz različnih anatomskih smeri. V ta namen smo orientirane smrekove vzorce impregnirali s pomočjo vakuuma z dvema bakrovima pripravkoma; vodno raztopino bakrovega(II) sulfata in komercialnim pripravkom Silvanolin. Rezultati so pokazali, da je izpiranje iz radialnih in tangencialnih površin primerljivo. Ugotovili smo, da se modra galica pri višjih koncentracijah najbolj izpira iz aksialnih ploskev, Silvanolin pa iz radialnih in tangencialnih površin. Due to the limited use of classical copper/chromium based preservatives, the industry seeks for alternatives for preservation of wood in ground applications. For such purposes, fungicides fixed in wood are utilised. For estimation of fixation, standard method that prescribes small specimens with higher portion of axial surfaces than in practice is utilised. The purpose of this article is to determine copper leaching from different anatomical planes.Orientated Norway spruce wood blocks were impregnated with aqueous solution of copper(II) sulphate and commercial preservative Silvanolin. The results showed comparable leaching from radial and tangential surfaces. However, more prominent leaching of copper(II) sulphate at higher concentrations and less extensive leaching of Silvanolin from axial surfaces was established. zaščita lesa baker etanolamin impregnabilnost navzem penetracija vezava wood preservation boron ethanolamine fixation impregnability penetration retention true false true Slovenski jezik Angleški jezik Znanstveno delo 2017-07-12 09:18:41 2017-07-12 09:18:41 2022-08-12 14:08:14 0000-00-00 00:00:00 2007 0 0 str. 23-25 Vol. 84 2007 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*8(045)=163.6 0351-3114 URN:NBN:SI:doc-GDGCNYS9 1609353 6206978 RAZ_Humar_Miha_i2007.pdf RAZ_Humar_Miha_i2007.pdf 1 3E9CDC31059352F58D90F742FCDB895D 5087d4606a52166a916e61274e409a024c6fd20eb174853d5bcdf6c672850b42 1ee11db8-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/5685f054-a467-403e-8807-7aedc2da5a1e https://dirros.openscience.si/Dokument.php?lang=slv&id=9499 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
