| Popis: | This study investigated the impact of two different heating rates (10 and 20 °C/min) on the thermal characteristics of three specific polymers: high-density polyethylene (HDPE), polypropylene (PP) and polyvinylchloride (PVC). A twin-screw extruder was employed to prepare the samples. In order to examine the influence of heating rate, differential scanning calorimetry (DSC) was used. The results of the differential scanning calorimetry (DSC) analysis, including the glass transition temperature (Tg), melting temperature (Tm), enthalpy change (ΔHm) and crystallization temperature (Tc), indicate that the melting temperature and enthalpy drops for polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC) when the heating rate increases. Furthermore, there is a minor alteration in the Tc . These studies are also of significant importance for the future of construction, which increasingly emphasizes ecological and sustainable solutions. |
