Claims (1)

생석회를 미립 석회 유화(微砬 石灰 乳化)는 온수 60℃이상 소화된 고형분(固形分) 100중량부(重量部)에 5-10중량부의 유산염(硫酸鹽) 수용액(水溶液)을 수산화 칼슘액에 첨가(添加)하고 전체 농도(濃度) 0.4-4.0중량% 현탁액(絃灘液)을 온도 15-30℃조제(調劑)한 다음에 암모니아가스(NH3Gas)를 주입 입체형태(粒締形態) 변화촉진(變化促進)되고 탄산을 흡입(吸入) 입자의 표면은 탄산이 균일하게 피복(被覆)되어 있는 것을 특징으로 하는 극 초미세 탄산 칼슘 제조방법.Fine lime emulsification is based on 100 parts by weight of solids digested with hot water above 60 ° C and 5-10 parts by weight of an aqueous solution of lactate in calcium hydroxide solution. After adding the solution, preparing a suspension of 0.4-4.0 wt% of total concentration at a temperature of 15-30 ° C., and then injecting ammonia gas (NH 3 Gas). A method of producing ultra-fine calcium carbonate, wherein the surface of the particles promoting change and inhaling carbonic acid is uniformly coated with carbonic acid. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
