Abstract
U ovom radu ispitan je utjecaj mehaničkog recikliranja na svojstva jednokratnih maski za lice. Jednokratne maske za lice su mehanički reciklirane koristeći jednopužni ekstruder. FTIR, TG i DSC korišteni su kako bi se odredila struktura i toplinska svojstva svakog sloja jednokratne maske za lice, jednokratne maske za lice prije i nakon recikliranja. FTIR analiza je potvrdila da je polipropilen glavni polimer sadržan u svakom sloju jednokratne maske za lice. Utjecaj recikliranja jednokratnih maski za lice na toplinska svojstva istražen je diferencijalnom pretražnom kalorimetrijom i termogravimetrijskom analizom. Neizotermnom termogravimetrijom utvrđeno je da recikliranje jednokratnih maski za lice nema utjecaj na toplinsku stabilnost. Primjenom diferencijalne pretražne kalorimetrije utvrđeno je da recikliranje utječe na kristalnost jednokratnih maski za lice.
Abstract (english)
In this paper, influence of mechanical recycling on the properties of a single-use face masks was examined. Single-use face masks were mechanically recycled by using a laboratory single-screw extruder. FTIR, TG and DSC were used to determine the structure and thermal properties of each layer of the single-use face mask, single-use face mask before and after recycling. FTIR analysis confirmed that polypropylene is the main polymer that composes each layer of the single-use face mask. The influence of recycling of a single-use face mask on its thermal properties was investigated by differential scanning calorimetry and non-isothermal thermogravimetric analysis. It was found by non-isothermal thermogravimetry that recycling does not affect thermal stability of single-use face masks. By using differential scanning calorimetry, it was determined that recycling affects the crystallinity of single-use face masks.
