20.500.12556/RUL-142327 Parametrična analiza iztiskavanja tankostenskega polimernega profila z metodo načrtovanja preizkusov Parametric analysis of the extruded thin wall polymer profile using design of experiment method Namen magistrskega dela je bila ugotovitev vpliva procesnih parametrov na iztiskavanje tankostenskega profila. Pri tem materiala nismo spreminjali, ampak je bil izbran predčasno. Za lažjo analizo smo uporabili metodo načrtovanja preizkusov, ki je narekovala, katere preizkuse na napravi za iztiskavanje smo izvedli glede na različne procesne parametre. Po zaključenih preizkusih smo iz profilov izdelali epruvete. Z njimi smo izvedli natezni preizkus in rezultate analizirali. Po končani analizi smo izvedli še potrditveni test. Ugotovili smo, da na natezno trdnost bistveno vplivata temperatura taline in vrtljaji polža naprave za iztiskavanje, medtem ko hitrost vleka nima bistvenega vpliva na natezno trdnost. The purpose of the master's thesis was to determine the influence of process parameters on the extrusion of a thin walled profile. In this case, we did not change the material, but it was chosen in advance. For ease of analysis, we used the Design of Experiment method, which dictated the tests we carried out on the extrusion machine, according to various process parameters. After the tests were completed, we made test tubes from the profiles. From them we performed a tensile test and analyzed the results. After the analysis, we performed a confirmation test. We found that the tensile strength is significantly affected by the temperature of the melt and the revolutions of the screw of the machine, while the pulling speed has no significant effect on the tensile strength. iztiskavanje polietilen metoda načrtovanja preizkusov tankostenski profil natezni preizkus diferenčna dinamična kalorimetrija extrusion polyethylene the design of experiment method thin wall profile tensile test differential scanning calorimetry true false false [M.
