20.500.12556/RUL-102564 Vpliv enkrat recikliranega polietilena visoke gostote na njegove termične lastnosti The influence of one time recycled high density polyethylene on its thermal properties HDPE je eden izmed najbolj razširjenih plastičnih materialov za vsakodnevno rabo. Njegova razširjena uporaba za seboj potegne negativne posledice, kot je onesnaževanje okolja. Reciklaža materiala je z vidika trajnostnega razvoja zelo zaželena. S tem namenom je potrebno poznati spremembe lastnosti materiala zaradi recikliranja, glede na osnovni nepredelan material. Ugotavljanje sprememb termičnih lastnosti in poznavanje njihovega pomena je tako potreben podatek, ki ga izkoristimo za ponovno obdelavo odsluženega izdelka. Zaključna naloga je namenjena ugotavljanju termičnih sprememb enkrat recikliranega polietilena visoke gostote v različnih mešanicah z osnovnim materialom in raziskovanju razlogov za morebitne spremembe. V praktičnem delu je pojasnjen postopek testiranja ter analiza na DSC napravi. Ugotovili smo, da enkratno recikliranje nima velikega vpliva na termične lastnosti, kot so temperatura tališča, kristalizacije in stopnja kristaliničnosti. HDPE is one of the most widely used plastic materials for everyday use. Its widespread use is causing negative consequences, such as environmental pollution. Material recycling is highly desirable in terms of sustainable development. For this purpose, it is necessary to know the changes in the properties of recycled material with respect to the base material. Finding changes in thermal properties and knowing their meaning is also necessary information that is used for the reprocessing of the waste product. The main goal of this thesis is intended for the determination of thermal changes of single-recycled high density polyethylene in various mixtures with basic material and exploring the reasons for possible changes. The practical part explains the testing process and the analysis on the DSC device. We found that single recycling has no significant influence on thermal properties, such as melting point, crystallization and degree of crystallinity.
