20.500.12556/DiRROS-7623 Izpiranje baker-etanolaminskih pripravkov iz lesa Leaching of copper-ethanolamine based preservatives from wood Baker-etanoilaminski zaščitni pripravki za les uspešno nadomeščajo klasične pripravke na osnovi bakra in kroma. V prispevku so opisani osnovni mehanizmi vezave, podrobneje pa je predstavljenih nekaj dejavnikov, ki vplivajo na izpiranje bakrovih učinkovin iz lesa. To so sestava in koncentracija pripravka, čas in temperatura vezave, uporabljena drevesna vrsta in postopek zaščite. Številni rezultati kažejo, da etanolamin bistveno izboljša vezavo bakrovih učinkovin v les, po drugi strani pa kasneje lahko povzroči tudi depolimerizacijo lesnih polioz, kar se kaže v intenzivnejšem izpiranju bakra iz lesa. Copper-ethanolamine based preservatives are successfully replacing classical copper-chromium based preservative solutions. In this paper, the proposed fixation mechanisms are described. Additionaly,basic facts that influence copper leaching from wood are elucidated: composition and concentration of solutions, time and temperature of fixation as well as wood species and treatment method used. The results show that addition of ethanolamine significiantly improves copper fixation, but can on the other hand cause depolymerisation of wood polymers, which results in increased leaching of copper. zaščita lesa bakrovi pripravki amini etanolamin vezava izpiranje fungicidnost wood preservation copper based preservation amines ethanolamine fixation leaching fungicidal properties true false true Slovenski jezik Angleški jezik Znanstveno delo 2017-07-12 09:18:38 2017-07-12 09:18:38 2022-08-12 14:07:20 0000-00-00 00:00:00 2006 0 0 str. 111-118 Vol. 80 2006 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*841 0351-3114 URN:NBN:SI:doc-VW7VCDWR 1474953 6206978 RAZ_Humar_Miha_i2006.pdf RAZ_Humar_Miha_i2006.pdf 1 F038F9E3BBB4479989A7B937A64CC125 b261461a405c5c0a50c8d341fcbe18afd03e975da28be65d5cb69463e8b35903 1e24a624-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/4f9e0f36-97d6-49ff-84f4-780af00e3109 https://dirros.openscience.si/Dokument.php?lang=slv&id=9489 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
