Charakterystyka degradacji biokompozytów z włókien i skrobi z palmy cukrowej
Języki publikacji
Abstrakty
In this work, sugar palm fibres (SPF) were used as a biodegradable reinforcement. SPF were incorporated into sugar palm starch (SPS) plasticised with glycerol using the compression molding process. Then the SPS and SPF/SPS biocomposites were submitted to biodegradation by means of soil burial experiments. The environmental effect on the SPS and SPF/SPS biocomposites were a loss in tensile strength of 78.09% and 53.67%, respectively, at the end of 72 hrs of the weathering testing period. The biodegradation test shows that SPS degrades very quickly and loses 63.58% of its weight at the end of 72 hrs compared to the SPF/SPS biocomposites.
Dla otrzymania biokompozytów zastosowano włókna z palmy cukrowej jako biodegradowalne wzmocnienie oraz matrycę ze skrobi tejże palmy. Plastyfikację przeprowadzono wykorzystując glicerynę w procesie wytłaczania. Gotowe biokompozyty były poddane biodegradacji przez umieszczenie w odpowiedniej glebie. Po 72 godzinach stwierdzono ubytek masy rzędu 78% podczas gdy w warunkach atmosferycznych stwierdzono ubytek masy około 54%. Stwierdzono również, że sama skrobia degraduje bardzo szybko i traci około 63% masy pod koniec 72- godzinnego okresu starzenia w warunkach atmosferycznych.
