Voski in njihova uporaba v lesarstvu

Lesar, Boštjan (author), Petrič, Marko (author), Kričej, Borut (author), Humar, Miha (author)

V prispevku so predstavljene osnovne značilnosti voskov in njihova delitev. Podane so lastnosti in uporaba voskov, ki se pogosto pojavljajo v lesarstvu (čebelji, karnauba, montanski, šelakov, parafinski in sintetični voski). Glavna lastnost voskov, ki jo v lesarstvu izkoriščamo, je njihova vodoodbojnost. Obdelava lesa z vodoodbojnimi sredstvi je v praksi zelo pogosta in se uporablja za zaščito pred navzemom tekoče vode ter za preprečevanje razvoja in rasti gliv. Najpogosteje se v ta namen uporablja parafinski vosek z dodatkom smol in biocidov. Vosek se na površini ne utrjuje kemijsko ampak se v lesno strukturo veže s šibkimi Van der Waalsovimi vezmi. To je vzrok, da voskana površina sčasoma izgublja vodoodbojni učinek.

Abstract

Basic characteristics of waxes and their classification are described in this contribution. Furthermore, basic prop- erties and potential uses of the most important waxes (bee, carnauba, montan, shellac, paraffin and synthetic wax) are described. These waxes are used in wood industry predominately due to their water repellency. Use of water repellents in wood industry is rather frequent procedure in order to limit water penetration and to prevent fungal infestation. Paraffin wax in combination with biocides and resins is the most commonly used for this purpose. However, waxes do not form chemical bonds with wood, but there are only weak Van der Waals bonds formed. This is the main reason for the fact, that wax treated surfaces lose hydrophobic properties within time.
