Izbira optimalnega polivinilacetatnega lepila za lepljenje sredice snežne deske : diplomsko delo (visokošolski strokovni študij) = Choosing the best polyvynilacetate glue for gluing snowboards core : graduation thesis (higher professional studies)Lesnjak, Damjan, 1979-Iskali smo najprimernejše PVA lepilo za lepljenje sredice snežne deske. Uporabili smo topolove lamele 1. kakovostnega razreda, 5 različnih tipov lepil skupine D3 in lepilo skupine D2. Po 2 lameli smo ... hladno zlepili pri 2 zaprto-odprtih časih. Za vsako kombinacijo smo zlepili 3 lepljence, skupaj torej 36. Po lepljenju smo preskušance klimatizirali 7 dni v standardni klimi. Polovico preskušancev smo nato 24 ur namakali v hladni vodi (SIST EN 204), drugo polovico pa 96 (prEN/TS 13354). Razlike v kakovosti lepljenja z različnimi lepili smo ugotavljali s preskušanjem strižne trdnosti lepilnega spoja. Povprečna strižna trdnost je bila pri vseh preskušancih dobra, razen tistih, zlepljenih z lepilom iz skupine D2. Trdnost lepilnega spoja preskusancev, namočenih 24 ur, je bila v povprečju za 40 % večja od preskušancev, namočenih 96 ur. Trdnost lepilnega spoja preskušancev, lepljenih pri zaprto-odprtem času 8 minut, je bila v povprečju višja za 5 % od preskušancev, lepljenih pri zaprto-odprtem času 1 minute. Razlika med lepilom najvišje in lepilom najnižje trdnosti lepilnega spoja iz skupine D3 je bila 21%. Trdnost lepilnih spojev je bila za vsa lepila skupine D3 sorazmerno visoka, najvišja pa pri KLEBIT-u 303 in MITOL-u 1130.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [D.
