Vpliv mešanja recikliranega in ne-recikliranega materiala na termične lastnosti HDPE materiala : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoTroha, Tadej, strojnikPlastični materiali so med najbolj uporabljenimi materiali v današnji industriji. S povečanjem proizvodnje plastičnih izdelkov, je hkrati potrebno ugotoviti kako ravnati z odpadki in pri tem paziti ... na trajnostni razvoj. Ena izmed rešitev je recikliranje in ponovna uporaba materialov. V sklopu zaključne naloge sem s pomočjo metode diferenčne dinamične kalorimetrije (DSC) izmeril temperaturo kristalizacije, temperaturo taljenja ter entalpijo taljenja iz katere se izračuna stopnja kristaliničnosti za polietilen visoke gostote, ki je bil recikliran do sto recikliranih ciklov. Recikliranemu materialu se je dodal tudi ne-recikliran material in sicer v razmerju ne-recikliran/recikliran = 10/90, 30/70, 50/50, 70/30, 90/10. Ugotovljeno je bilo, da se temperatura tališča zmanjša za 3,39 % in temperatura kristalizacije za 2,39 % po stotem ciklu recikliranja, glede na ne-recikliran material. Sprememba je zanemarljivo majhna in je v praksi nepomembna. Stopnja kristaliničnosti se po stotem ciklu recikliranja zmanjša za 13,26 %. Če recikliranemu materialu dodamo ne-recikliran material, v razmerju ne-recikliran/recikliran = 90/10 ali 70/30 se stopnja kristaliničnosti do stotega cikla recikliranja spremeni zanemarljivo malo in iz tega vidika lahko material ponovno uporabimoType of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [T.
