GYPSUM-BASED INVESTMENT MATERIAL COMPOSITION FOR CASTING AND METHOD FOR MANUFACTURING GYPSUM-BASED INVESTMENT MATERIAL COMPOSITION FOR CASTING
종래 제품으로 실현할 수 없었던, 방치 시간을 단축한 제품의 제공을 가능하게 하는, 급속 가열형의 석고계 매몰재로서 유용한 석고계 주조용 매몰재 조성물 및 그 제조 방법을 제공하는 것. 연화액을 넣고 연화 후에 경화시키고, 경화체를 고온의 노에 투입하는 급속 가열형의 매몰재용인 석고계의 분체상의 주조용 매몰재 조성물로서, 소석고와, 석영과, 크리스토발라이트를 주성분으로 해서 이루어지고, 소석고와 석영과의 공분쇄물, 소석고와 크리스토발라이트와의 공분쇄물 또는 소석고와 석영과 크리스토발라이트와의 공분쇄물로부터 선택되는 적어도 그 어느 하나의 공분쇄물과, 분체 혹은 수분 함유율이 낮은 액상의 보습성 성분을 포함하는, 평균 입자 지름이 30㎛ 이하인 석고계 주조용 매몰재 조성물 및 그 제조 방법.
The present invention intends to provide a gypsum-based embedding material composition for casting, the composition being useful as a rapid-heating type gypsum-based embedding material making it possible to provide a product with which leaving time is made short, which has never been realized in conventional products, and also intends to provide a method for producing the same. A gypsum-based embedding material composition for casting, the composition being a gypsum-based powdery embedding material composition for casting to be used for a rapid-heating type embedding material, the gypsum-based powdery embedding material composition being such that a set product is put into a high-temperature furnace, the set product obtained by adding a malaxation liquid into the composition to perform malaxation and then setting a resultant mixture, wherein the gypsum-based embedding material composition for casting contains as main components calcined gypsum, quartz, and cristobalite, and contains at least one co-pulverized material selected from a co-pulverized material of calcined gypsum and quartz, a co-pulverized material of calcined gypsum and cristobalite, or a co-pulverized material of calcined gypsum, quartz, and cristobalite, and a powdery moisture-retaining component or a liquid moisture-retaining component having a low water content, the composition having an average particle diameter of 30 µm or less, and a method for producing the same.
