Research Progress on Production and Application of Ground Calcium Carbonate

碳酸钙根据粉体不同的生产工艺和物理性质，分为重质碳酸钙和轻质碳酸钙。重质碳酸钙因其广泛的来源、廉价的价格、自身独特的性能已经成为非常重要的无机矿物材料，广泛地应用于国民经济中的工业、农业和日常生活的各个领域。本文详细介绍了重质碳酸钙的生产过程及其生产中的影响因素，综述了重质碳酸钙在涂料、橡胶、造纸、塑料中的应用现状，简要概括了重质碳酸钙的研究展望和发展趋势。 Calcium carbonate is generally divided into heavy calcium carbonate and light calcium carbonate according to different production processes and physical properties of the powder. Heavy calcium carbonate has become a kind of the most important inorganic mineral materials in modern times due to its wide sources, low price, and unique properties. It is widely used in various fields of industry, agriculture, and daily life in the national economy. This article provides a detailed introduction to the production process and influencing factors of heavy calcium carbonate, summarizes the current application status of heavy calcium carbonate in coatings, rubber, papermaking, and plastics, and briefly summarizes the research prospects and development trends of heavy calcium carbonate.
