Obtaining particulate agglomerates from the recycling of multilayer containers and low density polyethylene

Abstract

Currently, the interest and the need to innovate new materials through the use of waste materials has grown, which meet similar or improved physical, chemical and mechanical characteristics of the materials they will replace. During the present investigation, Multilayer Containers (EM) and Low Density Polyethylene (LDPE) were collected, particulate agglomerates with different proportions were obtained, the apparent density, water absorption, mass, volume, heat behavior, angle were determined. contact, machining and compression tests. With the objective of evaluating the proportions p / p in the properties. The advantage of the material obtained is that they do not generate waste and are 100% recyclable. The 90:10 ratio is the one that could be used in the construction industry as false walls, with a modulus of rupture of 52.7 N / mm2 and a compressive stress of 32.9 MP, because it can be machined without altering its characteristics. -physical houses; While the 85:15 and 80:20 proportions, since they cannot be machined, could be used as a floating support with a photocatalyst catalyst, due to the fact that these agglomerates have dimensional stability when in contact with water.

Obtaining particulate agglomerates from the recycling of multilayer containers and PET/Al/PE

“…In 2021, agglomerates were made with multilayer containers, they are reinforced with PEBD in different proportions, p/p, the physicalmechanical properties were evaluated, the materials obtained present a homogeneous matrix, they can be used in closed or open places for the construction of walls, are light, easy to machine, absorb 14.2% when submerged in water (Enríquez, Rosales, & Castrejón , 2021). Also, the mechanical properties of agglomerates of multilayer containers reinforced with low-density polyethylene (PEBD) and polyethylene terephthalate (PET) post-consumer (ratio w/p 90:10) have been evaluated, the compaction and integration between the materials were improved and the density, decreases water absorption and volumetric variation; therefore, they are ecological agglomerates, do not generate waste and contribute to reducing RSU In this work, two types of RSU are being combined, powdered milk containers (polyester/aluminium/polyethylene PET / Al/PE)) and multilayer containers (cardboard, polyethylene and aluminum), controlling physical variables such as: temperature , pressure and time in the thermoforming process, for the elaboration of agglomerates of dimensions 24*12*2 cm, in addition the resistance to compression is analyzed, for its possible use in the construction of interior and exterior walls in homes, ceilings or false walls in residential houses or as catalytic supports for the degradation of pollutants.…”
