Abstract
Da bi podaljšali trajnost lesa, ga poskušamo zaščititi na čim več možnih načinov. V sedanjem času vse bolj pridobivajo na pomenu naravne vrste zaščite. Ker je zaščita z biocidnimi pripravki vedno manj zaželena, strokovnjaki razvijajo nebiocidne pripravke, ki naj bi v zadostni meri preprečevale delovanje lesnih škodljivcev. Večina škodljivcev ne razkraja lesa, če je le-ta suh, zato smo se odločili, da preizkusimo, kako se impregnacija smrekovine in bukovine z vodnimi emulzijami montanskega, polietilenskega ali oksidiranega polietilenskega voska odlikuje v uravnavanju vlažnosti lesa na prostem. Glavni namen našega dela je bil analizirati vpliv klimatskih pogojev na vlažnost impregniranega lesa. Pol leta smo tedensko spremljali maso vzorcev impregniranega lesa, temperaturo okolja ter vlažnost zraka. Ugotovili smo, da so vsi voski zmanjšali higroskopnost bukovine, za smrekovino pa te teze nismo mogli potrditi.

Title:Influence of climate conditions on moisture content of wood impregnated with montan and polyethylene wax water emulsions : graduation thesis - higher professional studies
Abstract:
To improve durability of wood we protect it with different solutions. Nowadays, the importance of natural solutions is increasing. As biocidal treatment is less and less desired, there are newer, non-biocidal treatments developed that will limit the development of wood pests. In general, wood decay fungi do not degrade dry wood. To determine sorption properties, spruce and beech wood specimens were treated with montan, polyethylene, oxidized polyethylene wax emulsions. We studied how wax treated wood responds to the changes in moisture content and temperature. Therefore, the mass of the control and treated specimens were monitored weekly for 6 months. The results show that all the waxes have positive effects on sorption properties of beech wood, but we could not assure it for spruce wood.

Keywords:wood, wood preservation, water wax emulsion, montan wax, polyethylene wax, sorption
