Vpliv vlažnosti granulata na parametre brizganja in dimenzije izdelka iz poliamida : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje Strojništvo - Projektno aplikativni programKljučevšek, JožefV sklopu diplomske naloge smo preučevali vpliv vlažnosti granulata iz poliamida na končne dimenzije izdelkov ohišja in pokrova EFD 10. Znano je, da je za stabilen proces brizganja pred slednjim ... potrebno poliamid v obliki granulata predhodno sušiti. Sušiti ga je potrebno do predpisane stopnje vlažnosti, ki jo navaja proizvajalec granulata. Proizvajalec navadno poda zgornjo mejno vrednost vsebnosti vlage. Ugotoviti pa si želimo, kakšni vplivi na proces brizganja se skrivajo v predpisanem suhem področju in posledično kakšni so vplivi na končne dimenzije brizgancev. Za ugotavljanje vplivov smo pripravili vzorce z različno stopnjo vlažnosti. Za določanje vlažnosti smo posamezne vzorce pomerili na merilniku vlažnosti. Vzorce granulata smo zatem brizgali v navedena izdelka in spremljali potek parametrov brizganja. Za konec pa smo brizgane vzorce pomerili na koordinatnem merilnem stroju. Iz raziskave smo ugotovili, da ima vlažnost granulata vpliv predvsem na njegovo viskoznost ter posledično na brizgalne tlake. Nekoliko manjši oziroma zanemarljiv vpliv pa ima vlažnost granulata na končno maso izdelka ter na njegove dimenzije.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
