摘要：油墨专用碳酸钙在油墨行业中属于填充料及体质颜料，使用量较大，各种用途的油墨制品对碳酸钙的要求也有所不同。目前油墨专用碳酸钙都是采用石灰水碳化法进行生产，由于在碳化过程中同时发生氢氧化钙的溶解和碳酸钙的生成反应，反应过程复杂，如果浓度控制不当还会使生成的碳酸钙包覆于氢氧化钙颗粒表面，从而引起碳酸钙成核时间与碳酸钙颗粒成长时间的相互交叉，导致生成的碳酸钙颗粒大小不一、粒径分布宽。本课题尝试用液-液相反应法制备出一次粒径均匀的油墨专用碳酸钙。

Development of calcium carbonate for ink
Abstract: Special ink in the ink industry are calcium carbonate fillers pigment, with higher usage, ink products for various uses calcium carbonate requirements are different. Are currently used calcium carbonate lime ink dedicated to produce carbonization, carbonization process due to simultaneous dissolution of calcium hydroxide and calcium carbonate formation reaction, the reaction process is complex, if the concentration is properly controlled so that the resulting calcium carbonate package will cover on the surface of calcium hydroxide particles, causing calcium carbonate nucleation time and growth of calcium carbonate particles of cross-cutting time, lead to the generation of calcium carbonate particle sizes, particle size distribution width. This issue attempts with liquid - liquid phase reactions were prepared by a special ink uniform particle size calcium carbonate.
