Analysis of the whole industry chain of calcium carbonate development of new materials

Academy

As an important non-metallic mineral basic raw material in daily industrial production, calcium carbonate is at the forefront of the industrial chain, known as “industrial grain”, closely related to the national economy and life, and is an important supporting material for the development of emerging industries and high-tech . The main products of new calcium carbonate materials are modified plastic products, rubber products, wood-plastic products, artificial granite, sealant, stone paper, ink, paint and coating, etc.

Classification and application
Calcium carbonate is mainly divided into industrial calcium carbonate, edible calcium carbonate, and medicinal calcium carbonate. Industrial calcium carbonate is divided into heavy calcium carbonate (heavy calcium), activated calcium carbonate (modified calcium), light calcium carbonate (light calcium), and nano calcium carbonate (nano calcium). Widely used in papermaking, plastics, coatings, rubber, inks, chemical building materials, adhesives and sealing materials, feed, daily chemicals, food, medicine and many other fields, can also be used as dietary supplements and antacids, is the current application The most widely used and most used inorganic non-metallic mineral powder.

Calcium carbonate new material industry chain diagram
Upstream of new calcium carbonate materials are marble, limestone, stalactite, calcite, iceland stone, grinding and grading equipment. Calcium carbonate new materials are used downstream in plastics, architectural coatings, paints, papermaking, rubber, inks, pigments, adhesives, sealants, daily chemicals, toothpaste, food, medicine, aerospace technology and other fields and industries. In addition, with the popularization of automobiles and printers in China and the rapid advancement of new urbanization, the domestic market demand for automobile chassis paint, high-grade ink, new sealing materials, decorative wallpaper and other products will increase significantly. These are all new calcium carbonate. The development of the material industry provides a broad market space.

Development status and trend
At present, the competitive field of calcium carbonate products is mainly concentrated in the field of light calcium carbonate and nano-calcium carbonate. As one of the products with the highest technical content in nano-calcium carbonate products, surface-modified nano-calcium carbonate is also the focus of the industrial layout of various countries. my country has abundant and high-quality limestone, calcite and other resources and a broad consumer market. In recent years, it has maintained the status of the world’s largest calcium carbonate production and consumption country, and the production and consumption of light calcium carbonate has reached 50% of the world’s total. The production of heavy calcium carbonate accounts for more than 25% of the world’s total. Around the calcium carbonate resource and mineral fields, my country has gradually formed a number of calcium carbonate industries such as Hezhou in Guangxi, Yongfeng in Jiangxi, Jiande in Zhejiang, Nanzhao in Henan, Lianzhou in Guangdong, Quzhou in Zhejiang, Chizhou in Anhui, Jingxing in Hebei, Linwu in Hunan and Ya’an in Sichuan. base. However, due to the limitations of resources, technology, capital, site, cost control, etc., compared with foreign leading enterprises such as Omiya, Yingge Porcelain, and Huber, my country’s domestic calcium carbonate enterprises are generally smaller in scale, with backward production technology, low industrial level, and independent Insufficient innovation and low competitiveness, mainly for low-end filler grade products, insufficient development in high-end specialized and functional products, still not a strong country in calcium carbonate products. As my country’s economy gradually moves towards a high-quality green development track, the demand for high-end calcium carbonate products in plastics, rubber, coatings, papermaking and other industries will increase sharply, and the calcium carbonate industry has strong development prospects. The calcium carbonate industry is gradually developing from low-end primary processed products to high-end nano calcium carbonate, ultra-fine calcium carbonate, medical grade and food grade calcium carbonate products; at the same time, functionalized and specialized calcium carbonate products are also the future development of calcium carbonate products. direction. Some enterprises have been focusing on research and development of functional and high-performance products, and gradually penetrated into the high-end market.

Calcium carbonate industry development ideas
China’s calcium carbonate industry has long been in a factor-driven, extensional growth development model, with serious resource and energy consumption and environmental pollution, and a large gap with the new industrialization requirements of high technology content, good economic benefits, low resource consumption, and less environmental pollution. In the next few years, under the dual drive of external policy adjustment and internal competitive pressure, the development model of the calcium carbonate industry will gradually change to an innovation-driven one. , low energy consumption, low emission direction development.
It is necessary to treat resources well from the head of the calcium carbonate industry chain, adhere to green mining, intensive utilization, optimized rationing, and cascade utilization; the production process and equipment of calcium carbonate products in the chain should be green, intelligent and large-scale; the tail of the chain should be refined Specialization, specialization, functionalization and serialization. At the same time, increase the government’s guidance and support, strengthen the strong alliance between enterprises and enterprises, enterprises and scientific research institutes, give full play to the advantages, and believe that the future development of the calcium carbonate industry can be expected.
