Superfine calcium carbonate and preparation method thereof
The invention relates to the technical field of calcium carbonate material preparation, and particularly discloses superfine calcium carbonate and a preparation method thereof. The preparation method of the superfine calcium carbonate provided by the invention comprises the following steps: firstly, carrying out digestion reaction on quick lime and water, and then preparing the superfine calcium carbonate from the obtained calcium hydroxide suspension by using modified cotton hull powder as a calcium hydroxide dispersing agent and a calcium carbonate crystal form control agent, the process for preparing the superfine calcium carbonate solves the problems that calcium hydroxide is easy to agglomerate and the preparation process of the superfine calcium carbonate is complex, the granularity of the superfine calcium carbonate is reduced, the purity and the yield of the superfine calcium carbonate are greatly improved, the whole preparation process is low in cost, raw materials are easy to obtain, and no burden is caused to the environment; the process cost is greatly saved, the operability is high, the method is suitable for industrialized production, and a new thought is provided for preparation of superfine calcium carbonate.
本发明涉及碳酸钙材料制备技术领域，具体公开一种超细碳酸钙及其制备方法。本发明提供的超细碳酸钙制备方法，首先将生石灰和水进行消化反应，然后对得到的氢氧化钙混悬液，再利用改性棉花壳粉作为氢氧化钙的分散剂和碳酸钙的晶型控制剂，制得超细碳酸钙；本发明制备超细碳酸钙的工艺解决了氢氧化钙易团聚以及超细碳酸钙制备工艺复杂的问题，还降低了超细碳酸钙粒度，极大地提高超细碳酸钙的纯度和收率，整个制备流程成本低廉，原材料易得且不会对环境产生负担，大大节约了工艺成本，可操作性强，适合工厂化生产，为超细碳酸钙的制备提供了新思路。
