Abstract

Večina zaščitnih pripravkov za les predstavlja potencialno nevarnost za okolje in človeka, tako med postopkom zaščite, z uporabo lesa in obdelavo kot tudi popreteku življenjske dobe zaščitenega lesa. Zato si v zadnjem času prizadevamo za razvoj novih okolju prijaznejših postopkov zaščite. Ena od možnih rešitev je modifikacija lesa. Na vzorcih, modificiranih z različnimi silicijevimi spojinami, ki so jih pripravili na Inštitutu za biologijo in tehnologijo lesa v Göttingenu (Nemčija), smo opravili test v skladu s privzetim evropskim standardom SIST EN 152/2. Vzorci so bili izpostavljeni delovanju suspenzije spor gliv modrivk Aureobasidium pullulans in Sclerophoma pithyophilla. Ugotovili smo, da modifikacija s silicijevimi spojinami lesa ni zaščitila pred modrenjem, z izjemo Silikonata 1, ki je preprečil obarvanje vzorcev z glivami modrivkami.

Secondary title:	Resistance of wood modified with silicon compounds against blue stain fungi
Secondary abstract:	Most of the wood preservatives represent a potential danger for environment and human beings, while wood protecting, treating, using, and decaying. Therefore, lately, there is a tendency to develop a new environment friendly procedures to protect it. One of the possibilities is a modification. The specimens, modified with various silicon compounds, prepared at the Institute of Wood Biology and Technology in Göttingen (Germany), were tested then at faculty, in accordance with the SIST EN 152/2 standard instructions, and exposed to the suspension of blue stain spores Aureobasidium pullulans and Sclerophoma pithyophilla. It was found out that the modification with silicon compounds did not protect wood against blue stain fungi, with the exception of Siliconat 1, which prevented wood colouring.
