Abstract
Most of the European wood species does not have durable wood, therefore we have to impregnate if we want to use wood in outdoors applications. Relatively toxic compounds were utilised for such purposes in the past. Nowadays, we are interested in development of preservative solutions with the lowest possible negative environmental impact. One of the possibilities is use of montana and carnauba wax emulsions. Those waxes are the most stable natural waxes that form relatively thin film. We believe, that this film formed on the surface of the wood will prevent wetting, while film formed in the cell lumina will prevent the enzymes to penetrate into cell wall. The purpose of this project is to elucidate described theories and to prepare preservative solution, which will prevent fungal decay of wood.
Significance for science
- Studying of the interactions between wood and chemicals used broaden knowledge of the chemistry of preservative solutions and wood, as well as their interactions. - Investigation of the sorption properties of wood treated with various hydrophobic treatments improved understanding of the sorption properties that in certain cases are essential for understanding durability issues. - Studies of various biocidal and non-biocidal solutions improved understanding of biotica and abiotic degradation patterns. - Field test results were compared to laboratory ones, enabling us improvement and the reliability of laboratory procedures. - The performed project broaden knowledge in the field of wood, which is the basis for future research activities in this field. - All findings (relevant) were published in international publications. In parallel, the most important data were presented to the Slovenian public in the Slovenian language to improve and develop terminology and the scientific language. - Research in the framework of this project strengthen scientific international and national collaboration in the field of wood pests and wood preservation - Several students finished their BSC and MSC thesis on the topic of this project. - One PhD thesis were prepared and defended within the framework of this project. A young researcher was developed into top-tier scientists and professionals on the international level.
Significance for the country
- Wood stores carbon dioxide through its entire life. However, machining of wood is considerably less energetically demanding than machining competing materials (concrete, plastics, steel, aluminum…). Considering the substitution effect, using 1 m3 of wood prevents 2t of CO2 emission. With increased use of wood for construction applications, Slovenia could satisfy all the commitments of the Kyoto protocol. -Wood is the only natural and renewable material source in Slovenia. However, only 2/3 of the annual increment his arvested annually. Considerable amounts of wood therefore remain in the forests and disintegrate. It is thus of national importance to make better use of our wealth - wood. - A considerable percentage of the Slovenian national heritage is made of wood (wooden construction, sculptures, tools Etc.). This heritage is constantly threatened by wood decay fungi. The knowledge gained helped us to keep this heritage for our children. - Wood is an important source for infrastructure, too (poles, railway ties, bridges, noise barriers, fences Etc.). This infrastructure requires reliable protection. The collected data enable us to decide for proper preservative treatment. More reliable infrastructure will also enable more reliable electricity supply. - In addition, there are two research-education institutions involved in this project. All relevant knowledge gained was therefore transferred to students through lectures, practicals, diploma tasks and projects. - The development of analytical methods and the accumulation of knowledge in the production, characterization and manipulation of wood treated with various solutions in the proposed project enabled us to be in touch with the world’s scientific community – active participation, in wood science, as well as in the fields in which the other researchers of the project consortium are active. This project on the one side enabled us that, the popular image of wood science and technology was shifted from a field characteristic of the utilization of low-tech technologies to high-tech activity that generates high added value.
