Manufacturing method for spongy porous material with high acoustic absorption, involves preparing and homogenizing mineral-rich slurry, then impregnating matrix or suitable support into slurry prior to heating and drying

摘要

The method involves preparing and homogenizing slurry of mineral-rich materials. A matrix or other suitable support is injected into the slurry, after which the slurry is heated and dried, producing the porous material.
