Povzetek
Les, proizvod narave, material preteklosti, se je izkazal za nenadomestljivega. Njegova uporaba se iz dneva v dan povečuje. Sam les pa na žalost ni dovolj odporen, zato ga je treba predhodno zaščititi. Uporaba nebiocidnih pripravkov, kot so olja in voski z drugimi učinkovinami, je vse bolj pogosta. Da bi ugotovili, kakšna je njihova samostojna funkcija, smo na bukovini in smrekovini uporabili različna hidrofobna sredstva: laneno, tungovo in rustikal olje ter parafin in protektin. Polovico vzorcev smo izpostavili visoki relativni zračni vlažnosti, druge pa potopili v vodo. S spremljanjem mas in dimenzij smo dobili navzeme hidrofobnih pripravkov. Bukovina je bolj impregnabilna kot smrekovina, kar se odraža v večjem navzemu.V danih pogojih se je protektin kljub največjemu navzemu izkazal za najmanj učinkovitega. Med preizkušanjem, potapljanjem in kondiconiranjem v komori z visoko vlažnostjo, smo najnižje vlažnosti in s tem najboljše rezultate dosegli z vzorci, zaščitenimi s tungovim oljem pri obeh lesnih vrstah. Zaščita s tungovim, rustikal in lanenim oljem bolj učinkovito ščiti les pred navlaževanjem kot parafinska emulzija in protektin.

Hydrophobicity of wood impregnated with solutions based on linseed, tung and rustikal oils and paraffin emulsions |
Sekundarni povzetek: |
Wood, as product of nature and so much used in the past, still proves to be irreplaceable. Its usage increases constantly from day to day. Unfortunately, it is not resistant enough. Therefore, it has to be protected, especially when used in outdoor conditions. The use of non-biocidal solutions, such as oils and waxes, is increasing. To research non-biocidal solutions used to protect wood without biocidal ingredients, beech and spruce wood specimens were protected with different hydrophobic preparations: linseed, tung, rustikal oils, paraffin and protektin wax emulsions. Some samples were exposed to very high relative humidity, others just immersed in water. During the experiment, the weight and dimensions were monitored. Beech wood was more impregnable than spruce wood, reflected in higher retention values. The highest retention was obtained with protektin. Nevertheless; this solution exhibited the worst hydrophobicity. In both wood species, the tung oil proved to be the best. The results show that tung oil treated wood has the lowest humidity, regardless the method used. Tung, rustikal and linseed oil have better hydrophobic properties than paraffin emulsion and protektin. |
