Publicación Estudio de prefactibilidad para el proceso de transformación de Polietilen Tereftalato (PET) para la organización Corporación Fenalco solidario Colombia(Universidad EAFIT, 2020) Aristizábal Guisao, Juan Alejandro; Zapata Uribe, Sebastian; Gómez Salazar, Elkin Arcesio; CORPORACIÓN FENALCO SOLIDARIOPublicación Mejoramiento de la procesabilidad del PET reciclado : evaluación de mezclas poliméricas para mitigar degradación y mejorar estabilidad en la extrusión de filamento de impresión 3D con PET posconsumo(Universidad EAFIT, 2021) Lazo Lobo, José Roberto; Rodríguez Arroyave, Carlos ArturoA filament for 3D printing FDM (Fused Deposition Modeling) of recycled PET bottles and PETG was developed via melt blending in a low production filament extruder with the purpose of improving the processability of PET and expanding the recycling possibilities of both materials. As PETG is a commercial material used in FDM, the effect of this polymer in the mixture with PET was evaluated in terms of the diameter stability of the filament and the tensile properties in filament not yet printed. The choice of PETG was the result of a first stage of qualitative quality analysis, in which it was evaluated how other materials affected the stability of the process; An improvement in this was obtained by counteracting the degradation of PET during processing, and the mixture with PETG resulted in a regular morphology that indicates a certain degree of miscibility between the two polymers, in addition the results of maximum stress and elongation slightly improved the PETG This study explores alternatives to non-centralized, small and medium-scale recycling sites, thus reducing logistical expenses in the management of plastic waste by making use of the circular economy modelPublicación Morphology of HDPE/PET/E-GMA blends : study of the mechanism for toughening without rigidity loss(Universidad EAFIT, 2020) Feregrino Montes, Ciro; Ospina Salgado, Silvio Alberto; Ospina Salgado, Silvio Alberto
