Lezenje lepljenega lesa : diplomsko delo (visokošolski strokovni študij) = Creep of glued wood : graduation thesis (higher professional studies)
Zapušek, Borut
Raziskovali smo mehanosorptivno lezenje lepljenih in masivnih smrekovih preizkušancev. Za lepljenje smo uporabili 3 vrste konstrukcijskih lepil: melamin-urea-formaldehidno, melamin-formaldehidno in ...poliuretansko lepilo. Pripravili smo upogibne preizkušance, ki so imeli 1 ali 2 lepilna spoja. Preizkušance smo obremenili na upogib in jih izpostavili ciklični klimi za 28 dni. Klimo smo spreminjali vsakih 7 dni. Najprej smo vzdrževali vlažno klimo z okoli 90 %, nato pa suho klimo s 33 % relativno zračno vlažnostjo. Temperatura zraka je znašala 20 °C. Na osnovi meritev smo izračunali povprečne povese in relativno lezenje preizkušancev. Ugotovili smo, da so preizkušanci zlepljeni z enim poliuretanskim lepilnim spojem bolj podvrženi lezenju kot masiven les. Ostali lepljenci so lezli podobno ali manj kot masivni preizkušanci. Ugotovili smo, da so preizkušanci, zlepljeni z dvema lepilnima spojema melamin-formaldehidnega in melamin-urea-formaldehidnega lepila lezli bolj kot tisti z enim lepilnim spojem. Mehanosorptivni efekt je bil pri lepljenih preizkušancih podoben kot pri masivnem lesu.
