Valorización de residuos MDF, aglomerado y fibra de vidrio como materia prima para el proceso de construcción de materiales reciclados con propiedades de aislamiento acústico

Abstract

In the present investigation, it is proposed to build three different recycled materials from the recovery of waste generated in the acoustic industry (MDF, chipboard and fiberglass). Obtaining the three recycled materials was achieved through a manufacturing process that included waste classification, sieving, obtaining the net waste, forming three mixtures with the waste by adding resin, molding, drying and demoulding. The three final products obtained were subjected to an evaluation, to measure the acoustic insulation that each recycled material presents at different frequencies, using a soundproofing chamber, the insulation value in decibels of each final product was obtained. Being, the final product two, the one that presents a better behavior to attenuate the sound in order to give possible uses to the recycled material. Comparisons were presented between the acoustic insulation results of the three final products with various other materials used in acoustic conditioning, in addition to indicating the cost involved in manufacturing the three recycled materials, so that the acoustic company considers the proposal to benefit from a circular economy in its production process where the waste generated can be reused to obtain recycled materials with sound attenuation properties.
