Staranje toplotno obdelanih lesenih talnih oblog : diplomsko delo = Ageing of heat-treated wood floorings : B. Sc. thesisLesjak, Rok, 1989-Med življenjsko dobo lesenih talnih oblog prihaja do staranja ter s tem spreminjanja njihovih relevantnih lastnosti, ki pa jih je mogoče oceniti v krajšem času v simuliranih pogojih intenzivnega ... klimatskega obremenjevanja. V ta namen smo umetno pospešenemu staranju (UPS) izpostavili tri skupine zunanjih lesenih talnih oblog: v skupino A smo uvrstili le toplotno obdelane preizkušance, v skupinah B in C pa smo enake preizkušance še dodatno površinsko zaščitili z naravnim oljem. Med standardnim postopkom cikličnega obremenjevanja z ultravijoličnim obsevanjem, infrardečim segrevanjem in umetnim dežjem smo v intervalih po 100 ciklov UPS na preizkušancih ugotavljali spremembo mase in vlažnosti, barve, dimenzij ter pojavnost napak. Največje spremembe mase, dimenzij in barve smo zaznali že po prvih 100 urah obremenjevanja. Pri preizkušancih A so bile spremembe absolutno večje kot pri skupinah B in C, ki se med sabo nista razlikovali. Prve razpoke in pokline so se pojavile na preizkušancih skupine A že po 100 urah, pri skupinah B in C pa po 200 do 300 urah. Zaključujemo, da so se znaki staranja pri površinsko oljenih in toplotno obdelanih talnih oblogah pokazali kasneje in manj izrazito kot pri kontrolnih preizkušancih skupine A.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [R.
