Abstract

흡음성 천장용 타일 중에 통상적으로 존재하는 미네랄 울(mineral wool)의 전부 또는 일부를 대체할 수 있는 석고/셀룰로즈성 섬유 조성물을 기본으로 하는 흡음성 타일 조성물. 석고/셀룰로즈성 섬유 조성물을 경량 골재 및 복합 재료와 혼합하여 흡음성 천장용 타일 및 패널을 제조하기 위한 워터 펠팅 공정(water-felting process)에 사용되는 조성물을 형성한다. 셀룰로즈성 섬유의 바람직한 공급원은 석고 및 셀룰로즈성 섬유를 충분량의 물과 혼합하여 슬러리를 형성시킨 다음 가압하에 가열하여 석고를 하소시키고, 이를 알파 황산칼슘 반수화물로 전환시킴으로써 제조되는 석고/셀룰로즈 섬유 복합 재료이다. 생성된 복합 재료는 황산칼슘 결정과 물리적으로 상호 결합된 셀룰로즈성 섬유를 포함한다. 석고 및 셀룰로즈성 섬유의 또다른 공급원은 폐(스크랩)석고 벽판재이다. 팽창된 퍼얼라이트는 바람직한 결량 골재이다.
