Abstract

강청 컬럼과 같은 구조부재를 위한 분무가능한 내화성 조성물 뿐만 아니라 이들의 피복재를 다층 도포하는 방법을 제공한다. 상기 조성물은 포틀랜드 시멘트계물질, 치장벽토, 고밀오 혼합재 및 가속제를 포함한다. 상기 조성물은 포틀랜드 시멘트계물질의 전형적인 장시간 고화를 제거하고, 이들의 행어빌리티(hangability)를 향상시켰다. 포틀랜드 시멘트, 고밀도 혼합재, 치장벽토(반수화 황산 칼슘) 및 선택적으로 치장벽토 고화 응결지연제 및 분쇄 폴리스티렌 혼합재의 혼합물을 건식 혼합하여 생성물을 생성한다. 물을 첨가하는 순간, 도포지점까지 펌프할 수 있는 분무 가능한 슬러리가 형성된다. 투입지점과 근접하여 가속제를 첨가한다. 슬러리를 슬러리상으로 구조막에 부착하고 고화후 불 및 열에 대한 우수한 보호 효과를 나타낸다. 분무후 적용시의 슬러리의 상대적인 신속한 고화시간으로 인해 동 노동일내에 다층 피복재를 도포할 수 있다.
