Abstract

V zaključni nalogi se ukvarjamo z vplivom recikliranja polimerov na mehanske lastnosti izdelkov predelanih iz gospodinjskih odpadkov. V nalogi najprej preučimo različne vrste recikliranja. Sledi postopek opisa injekcijskega brizganja in opis obdelave materiala. V raziskavi uporabljamo več načinov merjenja, natezne trdnosti, diferenčno dinamično kalorimetrijo (DSC), tokovnih lastnosti, viskoznosti, meritvah viskoelastičnosti in meritvah linearne teorije viskoelastičnosti (LTVE). Z njimi opišemo mehanske lastnosti materiala. Ugotovili smo da, ima recikliranje vpliv na natezno trdnost, viskoelastičnost in tokovne lastnosti, medtem ko na DSC in LTVE meritve recikliranje ne vpliva.

Secondary title:	Impact of polymer recycling on the mechanical properties of products recycled from household waste
Secondary abstract:	In this thesis, we focus on the impact of polymer recycling on the mechanical properties of products recovered from household waste. In this thesis, we first look at the different types of recycling. This is followed by a description of the injection moulding process, from which a description of the processing of the material follows. In the study we also use several measurement methods, tensile strength, differential dynamic scanning calorimetry (DSC), flow properties, viscosity, highelasticity and linear theory of high elasticity (LTVE) measurements. These are used to describe the mechanical properties of the material. We found that recycling has an effect on tensile strength, highelasticity and flow properties, while DSC and LTVE measurements are not affected.
