Optimizacija brizganja POM z metodo Flash DSCLorber, Rebeka ...Povzetek (neobvezno): Pri brizganju delnokristaliničnih termoplastov so temperatura orodja, hitrost in čas ohlajanja med najpomembnejšimi parametri, ki določajo velikost in število kristaliničnih ... področij, ki znatno vplivajo na končne lastnosti brizganih kosov, predvsem kar se tiče mehanskih lastnosti in geometrijske stabilnosti. Metoda Flash DSC omogoča segrevanje in ohlajanje vzorcev polimernih materialov z velikimi hitrostmi segrevanja (2.400.000 °C/min) in ohlajanja (240.000 °C/min). Pri tem lahko določimo temperature steklastega prehoda, tališča, kristalizacije in hladne kristalizacije ter pripadajoče entalpije. Meritve lahko izvajamo v temperaturnem območju med -35 °C in 300 °C z vzorci mase med 10 ng in 1000 ng. V prispevku smo predstavili optimizacijo brizganja polioksimetilena (POM), z uporabo metode Flash DSC in primerjavo rezultatov s praktičnim primerom brizganih zobnikov, v smislu časa ohlajanja in temperature orodja, katerih vpliv na stopnjo kristaliničnosti materiala POM Delrin 100 NC010 smo zasledovali. Določili smo relativne stopnje kristaliničnosti materiala, ki jih dosežemo pri brizganju z različnimi temperaturami orodja in časi hlajenja, kar služi kot osnovna orientacija za optimalno izbiro čim krajšega časa cikla in najprimernejše temperature orodja.Source: Vir znanja in izkušenj za stroko : zbornik foruma : Portorož, 21. in 22. junij 2021 : [12. industrijski forum IRT] (2021, str. 135-138)Type of material - conference contribution ; adult, seriousPublish date - 2021Language - slovenianCOBISS.SI-ID - 71288835
