June 15-17, by the China Inorder Salt Industry Association calcium carbonate industry branch sponsored by the 2015 National Calcium carbonate Industry Annual Meeting held in Hezhou, Guangxi. The conference aims to promote exchanges and cooperation between research institutes and enterprises, promote the low-carbon, environmental protection, clean and green development of the calcium carbonate industry, and achieve quality and efficiency.
China Chemical News reporter learned from the meeting, the current calcium carbonate industry in various regions, the development of enterprises is very uneven, facing overcapacity, declining efficiency, low-end product competition and other issues. Ye Haiting, honorary president of the China Inorder Salt Industry Association, stressed that enterprises will be eliminated if they do not innovate. Calcium carbonate enterprises should put innovation into practice in production processes, products, marketing, culture and management, and strive to promote sustainable development of the industry.
Shuwen, president of the calcium carbonate industry branch of the China Inororal Salt Industry Association, said that to achieve quality efficiency, it is necessary to prevent low-level, homogenized and repeated construction through scientific and technological innovation and industrial restructuring; Under the guidance of the National Industrial Structure Adjustment Guidance Directory (revised in 2014), we will guide enterprises to transform and upgrade in energy conservation and emission reduction, quality reduction and consumption reduction, brand efficiency, etc., so as to achieve the same weight, and make articles on special, refined, special and new. The so-called light weight, that is, calcium carbonate production enterprises should be light, heavy calcium carbonate production at the same time, under certain conditions will be organic combination of the two, so as to maximize product benefits.
, Deputy Secretary-General of China Inorance Salt Industry Association, believes that the restructuring of industry products should increase the proportion of production of specialized and refined products and reduce the output of low-performance products. Based on the drying capacity of the equipment and the experience accumulated over the years in the development of the industry, medium-sized enterprises are suitable for "532" and small enterprises are suitable for the "311" capacity structure model. These three figures represent the ratio of light calcium carbonate, active calcium carbonate and heavy calcium carbonate. The capacity structure can be implemented to realize water recycling and reduce wastewater discharge during the production process. In addition, qualified enterprises should speed up the development of intelligence, network, with information technology to transform the process, in a new round of scientific and technological revolution and industrial transformation and upgrading to win the initiative.
Yongqi, vice president of Hebei University of Science and Technology and head of the group of experts of the calcium and magnesium branch of the China Inorgestic Salt Industry Association, pointed out that scientific and technological innovation in the calcium carbonate industry should find breakthroughs in both production processes and equipment. Among them, the production process should be to the production of functional and specialized products in the direction of development, improve the added value of products. For example, the development of heavy calcium carbonate products dedicated to an industry adds several times or more value to ordinary products. For example, by making surface changes to existing low-end products, the production of special crystalline calcium carbonate filled into plastics can improve the performance of plastics, while greatly reducing production costs. Production equipment, should aim at energy conservation and consumption reduction, promote China's equipment on the basis of large-scale development to high-end refinement direction, and gradually catch up with the advanced level abroad.
Zhejiang Luzhou five-star calcium Industry Co. , Ltd. chief engineer Fang Xiaoxia told reporters that China's calcium carbonate raw materials are rich, modified production of high-performance calcium carbonate products can completely replace carbon black, white carbon black,

and other fillers, to achieve cost reduction, increase profits.

Calcium carbonate production process is divided into two main categories: one is light calcium carbonate (light calcium), made by limestone through chemical methods, long production process, "three waste" emissions, but fine particles, high product quality, can meet a variety of user requirements. The other category is heavy calcium carbonate (calcium), that is, limestone and other directly broken, ground into products. Heavy calcium production process is short, "three waste" emissions are small, low energy consumption.
In recent years, developed countries pay attention to the development of heavy calcium production technology, with the progress of heavy calcium processing equipment and grading technology, a variety of plastics, paper and other major downstream industries to meet the fine calcium carbonate products have come out, production enterprises basically use energy-efficient large-scale equipment and advanced production technology, products large-scale replacement of light calcium, environmental protection effect is remarkable. However, the development of China's calcium carbonate industry has long been more important than light calcium production, heavy calcium production development is slow. At present, the ratio of heavy calcium to light calcium used in the plastics industry in developed countries is 20:1, while the ratio of heavy calcium to light calcium used in China's plastics industry is only about 2:1, far lower than in developed countries.carbonate is modified on the basis of ordinary calcium carbonate, which can be filled and modified in composite products. These changes include changes to the crystalline form, particle size distribution and surface properties of calcium carbonate to improve its overall performance.
