my country’s light calcium carbonate industry chain has been formed and output is gradually increasing

Light calcium carbonate is also called precipitated calcium carbonate, or light calcium for short. It appears as a white powder with no pungent odor under normal temperature and pressure. It is difficult to dissolve in water and alcohol solutions and has slight moisture absorption ability. At this stage, the preparation technology of light calcium carbonate in my country is gradually mature, which can be roughly divided into soda calcium chloride method, combined calcium method, carbonization method, Solvay method, caustic soda method, etc. Among them, the carbonization method has become the mainstream process for producing light calcium carbonate in my country.

At present, my country’s light calcium carbonate industry chain has been basically mature. The upstream of the industrial chain is mainly the raw material industry, providing calcium chloride, limestone, carbon dioxide and other raw materials; the midstream is mainly the light calcium carbonate production industry, responsible for the production and manufacturing of light calcium carbonate; the downstream is the main application field, mostly used in plastics, Coatings, building materials, rubber, paper, ink, medicine, metallurgy and other fields.

In recent years, my country’s economic level has gradually improved and its industrialization has deepened. As a basic chemical material, light calcium carbonate has a huge consumer market. In the field of rubber, light calcium carbonate can be used directly as a filler to improve processing performance, increase volume, and reduce costs. Light calcium carbonate can also be used as a filler and stabilizer in building materials to improve their durability and fire resistance. In addition, lightweight calcium carbonate can also improve the hardness, heat resistance and dimensional stability of plastic products. Overall, my country’s market demand for light calcium carbonate is relatively large.

According to the “China Light Calcium Carbonate Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It shows that driven by downstream market demand, my country’s light calcium carbonate enterprises have gradually expanded their production scale and increased their output. In 2022, my country’s light calcium carbonate output will be 14.308 million tons, a year-on-year increase of 2.5%. From the perspective of output distribution, the main production areas of light calcium carbonate in my country are concentrated in Guangdong, Jiangxi, Zhejiang, Anhui, Henan, Hebei and other provinces. At present, my country has formed five major light calcium carbonate production bases, namely Enping in Guangdong, Nanzhao in Henan, Jiande in Zhejiang, Jingxing in Hebei, and Yongfeng in Jiangxi. Against the background of my country’s increasingly stringent environmental protection requirements, the production center of light calcium carbonate has gradually shifted from the eastern region to the central and western regions.

Industry analysts said that because foreign light calcium carbonate companies started earlier and have more advanced production technologies, they are mainly concentrated in the high-end market. my country’s light calcium carbonate enterprises started relatively late, there is a certain gap between production technology and international advanced technology, and there are relatively few product types. As my country’s light calcium carbonate enterprises continue to develop, the gap with foreign enterprises has gradually narrowed, and market competitiveness has gradually increased. At present, my country’s largest light calcium carbonate companies mainly include Lanhua Huaming, Jiawei Chemical, Warner New Materials, Jinshan New Materials, Guangping Chemical, etc.
