Downstream market boosts the growth rate of nano-calcium carbonate by 15%
随着下游行业生产技术与理论的不断发展，碳酸钙已由原来单纯的填充剂变为一种新型的功能性填充材料，应用领域不断拓展，其填充的比例也越来越高。在发达国家的需求量将以年均10%的速度增长，在中国将以年均20%的速度增长。
With the continuous development of production technology and theory in the downstream industry, calcium carbonate has changed from a simple filler to a new type of functional filler material, and its application field has been expanded, and its filling proportion is also increasing. The demand in developed countries will grow at an average annual rate of 10%, and in China will grow at an average annual rate of 20%.
碳酸钙填充的塑料制品更符合环保理念，越来越受到人们的认可，在治理"白色污染"方面必将发挥更大的作用。
The plastic products filled with calcium carbonate are more in line with the concept of environmental protection and are more and more recognized by people, and will play a greater role in the treatment of "white pollution".
碳酸钙填充量大于30%的塑料制品，是容易充分燃烧的，而且不会因粘接壁炉引起爆炸，燃烧的热能还可以回收利用。
Plastic products filled with more than 30% calcium carbonate are easy to fully burn, and will not cause explosion due to adhesion to the fireplace. The burning heat can also be recycled.
上世纪五十年代起，国内就开始生产轻质碳酸钙。到目前为止，国内的碳酸钙生产企业有上千家，其中轻质碳酸钙生产企业约500家，纳米碳酸钙生产企业约40余家，生产设计能力超过150万吨。近年来，随着碳酸钙超细化、结构复杂化及表面改性技术的提高，使碳酸钙产品向专用化、精细化、功能化方向发展，纳米级活性碳酸钙的应用得到拓展，塑料、橡胶、特殊纸制品、轿车漆几个主要行业对纳米级活性碳酸钙有较大的需求量，预计下游应用行业对其需求量每年以15%的增长率增长。
Since the 1950s, light calcium carbonate has been produced in China. So far, there are thousands of domestic calcium carbonate production enterprises, including about 500 light calcium carbonate production enterprises and about 40 nano-calcium carbonate production enterprises, with a production design capacity of more than 1.5 million tons. In recent years, with the refinement of calcium carbonate, the complexity of its structure and the improvement of its surface modification technology, calcium carbonate products have been developed towards specialization, refinement and functionalization, and the application of nanoscale activated calcium carbonate has been expanded. The major industries such as plastics, rubber, special paper products and car paint have a large demand for nanoscale activated calcium carbonate, and it is expected that the demand of downstream application industries will increase by 15% annually.
