| description | Efforts to utilize and improve the value of pulp
waste have been done by using primary sludge (still containing cellulose) and
fly ash as a filler to produce composite foam polystyrene (PS)-based as sound
absorbent. In this study, the composite foam was produced by mixing primary
sludge and fly ash with several compositions such as PS, PS/PS-g-MA/primary
sludge/fly ash (80/10/10/0), (80/10/7/3), (80/10/5/5), (75/10/10/5), and
(75/10/12/3). The composite was characterized based on ISO 11654:1997,
mechanical properties, thermal analysis using TGA and DSC, morphology using
SEM, crystallinity using XRD, and chemical analysis using FTIR. The results
showed that the band at 1600.63 cm-1 was sharper due to a chemical
reaction being formed between PS, primary sludge, and fly ash. The XRD analysis
showed a new diffraction peak in the 2 = 21-24o. The morphology analysis showed that primary
sludge and fly ash were uniformly dispersed into PS, increasing the mechanical
properties and decreasing the melting point of the PS foam composite. The sound-absorbing composite produced had
qualified ISO 11654:1997 on the rating level of the sound absorption
coefficient on materials for rooms with sound absorption classes D and C with
the value of w
0.328-0.793. |
