Nuevos materiales absorbentes acústicos obtenidos a partir de restos de botellas de plástico

Abstract: RESUMENEn el ámbito de acústica de la edificación es común el uso de materiales fibrosos como materiales absorbentes acústicos. Uno de estos materiales cada vez más utilizado es la lana de poliéster. Un problema que presenta el chip virgen de poliéster es que se obtiene del petróleo, cuyo precio no hace más que incrementarse en los últi-mos años. En este trabajo se presenta una lana de poliéster alternativa, obtenida mediante el tratamiento del PET, a través del conveniente ciclo de reciclado de botellas de pl… Show more

“…Meeting these conditions and taking the standardised reverberation chamber of the Higher Polytechnic School of Gandia, which has a volume of 238 m 3 , as a reference, the design of the small-sized reverberation chamber is shown in Figure 1 a. Figure 1 b shows the small-sized chamber when built.…”

“…Several examples of recycled materials can be found in Del Rey et al (3) with plastic bottle recycling, in Maderuelo et al (4) with tyre recycling, or in Del Rey et al (5) with recycled foams. Other examples of natural based materials can be found in Fatima and Mohanty (6) with jute, in Ramis et al (7) with kenaf, in Ramis et al (8) with coconut, in Diaz et al (9) with reed, in Arenas et al (10) with cellulose, or in Bulent et al (11) with tea fibres.…”

“…Empirical models have been subsequently applied to characterize polyurethane foams (Dunn and Davern 1986), plastic open-cell foams (Wu 1988), textile fibers (Garai and Pompoli 2005), different vegetal fibers (Ramis et al 2010;Fatima and Mohanty 2011;Oldham et al 2011;Navacerrada et al 2014), and recycled polyester fibers (del Rey et al 2011). In fact, the European standard on building acoustics (EN 12354 2003) recommends using the regression coefficients of Delany and Bazley (1970) for the prediction of the sound absorption of materials composed of fibers and the results of Dunn and Davern (1986) for foam materials.…”
