Vpliv debeline UF lepilnega sloja na strižno trdnost lepilnega spoja : visokošolska (univerzitetna) diplomska naloga = Influence of UF adhesive film thickness on shear strength of glued joints : graduation thesis
Novak, Milan
Raziskovali smo vpliv debeline UF sloja lepila na strižno trdnost lepilnega spoja. Pred nanosom lepila smo v eno stran bodočega lepljenca izdelali utore 18 različnih globin (0mm-2,20mm), s katerimi ...smo določili približno debelino sloja lepila zlepljenih preizkušancev. Lepljenci so bili zlepljeni po hladnem postopku. Točno debelino lepilnega sloja smo izmerili s stereo mikroskopom za ugotavljanje debeline branik lesa. Strižno trdnost smo ugotavljali s pomočjo trgalnega stroja v laboratoriju. S pomočjo računalniškega programa Excel smo podatke ustrezno obdelali in jih grafično prikazali. Ugotovili smo, da debelina sloja UF lepila v območju 0,05mm-1,70mm vpliva na strižno trdnost lepilnega spoja. Z naraščanjem debeline sloja lepila strižna trdnost pada. Trendu padanja se je najbolj približala eksponentna krivulja s koeficientom korelacije: r=0,912. Na strižno trdnost verjetno vpliva tudi sprememba kakovosti sloja lepila oziroma lepilnega sloja, kar pa nismo ugotavljali.
