Vpliv impregnacije lesa na strižno trdnost lepilnega spoja : diplomsko delo (visokošolski strokovni študij) = Influence of wood impregnation on shear strength of wood adhesive bond : graduation thesis (higher professional studies)Brezovšek, RajkoRazvili smo nov izdelek, pri katerem je ključnega pomena lepilni spoj impregniranega lesa. Z opravljenimi preskusi smo ugotovili, katero lepilo je dovolj kakovostno za proizvodnjo tega izdelka. ... Zahteve zanj so dokaj visoke: zaradi tehnoloških in ekonomskih razlogov mora biti hladno utrjujoče, odporno na vremenske pogoje in mora kakovostno lepiti predhodno impregniran les. Izbirali smo med 3 lepili: med UF (Lendamin-220), PUR (Mitopur) ter RF (Dynosol S-199) lepilom. Za izdelavo novega izdelka smo uporabili bukove (Fagus sylvatica L.) okroglice, iz katerih smo izdelali preskušance za ugotavljanje kakovosti zlepljenosti. Pri izdelavi in preskušanju preskušancev smo upoštevali zahteve, ki jih predpisuje standard SIST EN 205. Ugotavljali smo strižno trdnost lepilnega spoja. Polovica preskušancev je bila neimpregnirana, polovico pa smo impregnirali s Silvanolom-GBP. Preskušance smo pred preskušanjem pripravili skladno s standardom SIST EN 12765. Rezultati preskusov so jasno pokazali, da je za lepljenje novega izdelka najustreznejše RF lepilo, ker smo z uporabo tega lepila dosegli najvišje strižne trdnosti lepilnih spojev. Tudi delež loma lepilnega spoja po lesu je bil pri RF lepilnih spojih najvišji.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [R.
