20.500.12556/RUL-138586 Borove spojine za zaščito lesa Vezava v les ter fungicidne in insekticidne lastnosti Boron compounds for wood preservation V prvem delu članka smo predstavili zgodovino uporabe in toksične lastnosti borovih spojin, v drugem delu pa je predstavljeno delovanje borovih spojin na glive razkrojevalke, glive modrivke, insekte in termite. V sklepu so na kratko opisana zaščitna sredstva na osnovi borovih spojin, ki jih proizvajajo slovenski proizvajalci. Bor dobro difundira v les, kar omogoča dobro globinsko zaščito, po drugi strani pa je dobra difuzivnost vzrok za njegovo izpiranje iz lesa. Kar je največja slabost in omejitev pri uporabi borovih spojin. Zato je eden od glavnih izzivov v prihodnosti poiskati sredstvo oziroma mehanizem, ki bi preprečil izpiranje bora. S tem bi se njegova uporaba v zaščiti lesa močno povečala, saj borove spojine ustrezajo vedno ostrejšim okoljskim standardom. History and toxicological properties of boron compounds were presented in the first part of the article. In the second one fungicidal (blue stain and decay fungi), insecticidal and termiticidal properties of boron (B) and its compounds are described. At the end wood preservatives on the basis boron compounds produced by Slovenian producers are described. However, despite of the long tradition of boron utilisation for wood preservatives, commercial solution for improving boron fixation in wood is not available yet. This is the most important drawback of boron based wood preservative solutions. Therefore, it is one of the most important future goals to find method or technique for preventing boron leaching. This would even increase its usage, as boron fully fulfils all environmental demands. zaščita lesa bor borove spojine toksičnost izpiranje odpornost na razkroj wood preservation boron borates toxicity decay resistance leaching true false true Slovenski jezik Angleški jezik Članek v reviji 2022-07-29 09:50:49 2022-07-29 09:50:49 2022-09-15 04:16:56 0000-00-00 00:00:00 2007 0 0 Str. 216-222 št. 9/10 Let. 59 2007 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2007-01-01 630*841.14 0024-1067 1606281 RAZ_Lesar_Bostjan_2007.pdf RAZ_Lesar_Bostjan_2007.pdf 1 428E40F4FC9DD79E843A54F225896D4A f478982d371dc2a5770cac40e7309aa0e9fea8b2bb6074fd94a7d5aae29b573e d4f128d9-0f13-11ed-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=158957 Biotehniška fakulteta Les 0 0 0
