Sorpcijske lastnosti lesa impregniranega z vodno emulzijo montanskega voska in borove kisline : diplomsko delo - univerzitetni študij = Sorption properties of wood impregnated with montan wax emulsion and boric acid : graduation thesis - university studiesMelanšek, ŽigaBorova kislina je že v majhnih koncentracijah zelo učinkovit biocid, ki neznatno škoduje ljudem in okolju. Žal pa se v les slabo veže in se iz njega izpira. Številni avtorji poročajo, da borove ... spojine povečajo higroskopnost lesa. Za izboljšavo vezave in učinkovitosti smo jih kombinirali z vodno emulzijo montanskega voska različnih koncentracij. Pričakovali smo, da bo impregnacija z vodnimi emulzijami voska znižala vlažnost impregniranega lesa med potapljanjem v vodo in uravnovešanjem v vlažnem okolju. Vzorce iz smrekovine smo vakuumsko impregnirali z izbranimi zaščitnimi pripravki na osnovi montanskega voska in borove kisline. Pripravili smo 2 tipa vzorcev: 240 za ovrednotenje hitrosti navlaževanja v vodi in zraku, 110 za določanje sorpcijskih krivulj v 5 različnih klimah (20 %, 33 %, 65 %, 87 % in 98 %). Ugotovili smo, da je impregnacija z vodno emulzijo voska upočasnila adsorpcijo vode v impregnirani les. Poleg tega smo potrdili, da kombinacija emulzije voska in borove kisline ne izboljša le delovanja proti glivam razkrojevalkam, temveč se odraža tudi v ugodnejših sorpcijskih lastnostih impregniranega lesa.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [Ž.
