Estudio de las propiedades reológicas del material HDPE reciclado en múltiples ocasiones.

Abstract

[ES] La reutilización de materiales poliméricos es importante para el desarrollo sostenible, donde el reciclaje desempeña un papel importante en la reducción de materiales de desecho. Desafortunadamente, algunas de las propiedades de los materiales poliméricos cambian durante el proceso de reciclaje. El objetivo del estudio es determinar cómo las propiedades reológicas del polietileno de alta densidad (HDPE), que están asociadas con las propiedades de procesamiento, cambian con el reciclaje repetido.

[EN] The reuse of polymeric materials is important for sustainable development, therefore the recycling plays an important role in reducing waste materials. Unfortunately, some of the properties of recycled polymer materials can change during the recycling process. The study will be focused on the high-density polyethylene (HDPE), which is the most recycled plastic. Its long virtually unbranched polymer chains are responsible for high density, high strength and high stability compared to some other polymers. HDPE was first used for pipes in storm sewers, drains and culverts, although nowadays the use of this plastic is very extended for products like milk jugs, juice containers, grocery or trash bags, motor oil containers, shampoo and soap bottles, detergent and bleach containers or toys. The aim of the study is to investigate the properties of extensively recycled HDPE. The mechanical recycling will be simulated by an extrusion process. The mixtures of neat material with different ratios of extensively recycled HDPE will be used to determine how various properties of high-density polyethylene (HDPE), which are associated with the processing and final use of the product, change with repeated recycling and how the addition ofextensively recycled HDPE to neat material affects various properties.
