A LOW-DENSITY HIGH-STRENGTH CERAMSITE PROPPANT
Disclosed is a low density and high strength ceramsite proppant. The ceramsite proppant is manufactured by a method comprising a step of crushing a raw material into coarse powder and dry grinding the same; a step of adding fly ash, calcium hydroxide, cryolite, kaolin, and the like into the coarse powder; a step of obtaining mixed powder by inputting the resultant into a ball mill, conducting ball milling for 30 minutes to 2 hours, and sieving the same; a step of obtaining mixed slurry by mixing a cesium fluoride solution and a poly vinyl alcohol solution at a mass ratio of 1:7 to 1:15; a step of obtaining particles by mixing the mixed powder and the mixed slurry and granulating the resultant; a step of manufacturing a ceramsite blank by sintering the particles at high temperatures; and a step of adding alumina powder to the ceramsite blank to conduct polishing and removing the powder. According to the present invention, availability of waste can be improved.
본 발명은 저밀도(low-density) 고강도(high-strength) 세람사이트(ceramsite) 프로판트(proppant)를 개시하며, 원료(raw material)를 조분말(coarse powder)로 분쇄(crushing) 및 건식-그라인딩(dry-grinding)하는 단계; 플라이 애시(fly ash), 수산화칼슘(calcium hydroxide), 빙정석(cryolite), 고령토(kaolin) 및 기타 같은 종류의 것(the like)을 조분말(coarse powder)에(into) 첨가하는 단계; 결과물을 볼 밀(ball mill)에 넣어 30분 ~ 두 시간 동안 볼 밀링(ball milling)을 수행하고, 체질(sieving)하여 혼합 분말(mixed powder)을 구하는 단계; 플로오르화 세슘(cesium fluoride) 용액(solution)과 폴리비닐 알코올(polyvinyl alcohol) 용액(solution)을 1:7 ? 1:15의 질량비(mass ratio)로 혼합하여 혼합 슬러리(mixed slurry)를 구하는 단계; 혼합 분말(mixed powder)과 혼합 슬러리(mixed slurry)를 혼합하고(mixing), 그 결과물을 입자화 하여(granulating) 입자(particles)를 구하는 단계; 입자(particles)를 고온 소결(sintering)하여 세람사이트(ceramsite) 블랭크(blank)를 제조하는 단계; 그리고 폴리싱(polishing)을 위하여 알루미나(alumina) 분말(powder)을 세람사이트(ceramsite) 블랭크(blank)로 추가하고, 그리고 분말(powder)을 제거하는 단계;로 구성되는 방법에 의해 제조된다.
