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
