Abstract
U ovom radu istraživan je utjecaj mehaničkog recikliranja ekstrudiranjem na strukturu i toplinska svojstva poli(etilen-tereftalata). Ekstrudiranje je provedeno u jednopužnom laboratorijskom ekstruderu. Infracrvena spektroskopija primijenjena je za određivanje utjecaja mehaničkog recikliranja na strukturu poli(etilen-tereftalata). Usporedbom dobivenih spektrograma s podatcima u literaturi utvrđeno je da su prikupljene boce doista izrađene od poli(etilen-tereftalata). Također je utvrđeno da mehaničko recikliranje, odnosno ekstrudiranje nije značajno utjecalo na strukturu istraživanog poli(etilen-tereftalata). Primjenom diferencijalne pretražne kalorimetrije određeni su karakteristični toplinski prijelazi staklište, talište, kristalište i stupanj kristalnosti. Utvrđeno je da mehaničko recikliranje nije značajno utjecalo na staklište i talište istraživanog poli(etilen-tereftalata), dok se temperature kristališta značajno razlikuju.
Abstract (english)
In this work the results influence of mehanical recycling by extrusion on the structure and thermal properties of poly(ethylene terephthalate) has been investigated. Mechanical recycling was performed in a single screw laboratory extruder. Infrared spectroscopy was used to determine the influence of mechanical recycling on the structure of poly(ethylene terephthalate). Comparing the obtained spectrographs with the literature data has shown that the collected bottles were indeed made of poly (ethylene terephthalate). It has also been found that mechanical recycling, or extrusion, did not significantly affect the structure of the poly(ethylene terephthalate). Using differential scanning calorimetry, characteristic thermal transitions (glass point, melting point, crystallinity, and degree of crystallinity) have been defined. Mechanical recycling did not significantly affect the glass and melting point of the poly (ethylene terephthalate) while the crystallization temperatures differed significantly.
