Since the 21st century, China's titanium dioxide industry has entered a period of rapid integration and comprehensive development. The annual consumption of titanium dioxide in China's inland has nearly quadrupled, forming a beautiful landscape of "the Chinese era of the global titanium dioxide industry". Not only has the production capacity and output of titanium dioxide become the first in the world, becoming the largest producer and consumer of titanium dioxide in the world, but the entire titanium dioxide industry has made great progress in production technology, product quality, export pattern, etc.
——The global proportion has significantly increased. In recent years, the production capacity and output of titanium dioxide in China have increased rapidly, becoming the country with the largest production capacity and output of titanium dioxide in the world. The production capacity of titanium dioxide, which was only 340000 tons in 2000, increased seven times to 2.43 million tons in 2011, and its proportion in the global production capacity jumped from 6.7% to more than 20%; The output of titanium dioxide was only 290000 tons in 2000, and increased to 1755000 tons in 2011, an increase of nearly six times. The growth rate is far higher than the world average, especially the rutile products. The annual output of titanium dioxide increased from 2.73 tons in 2000 to 1.176 million tons in 2011, accounting for more than 67% of the total output of titanium dioxide from 9.41%, just accounting for 2/3 of the total output of the industry, further approaching the international proportion of 85% to 90%.
——The enterprise scale and industry concentration ratio have significantly improved. By the end of 2011, there were 40 titanium dioxide production enterprises with an annual output of more than 10000 tons, 8 medium-sized enterprises with an annual output of more than 50000 tons, and 3 large enterprises with an annual output of more than 100000 tons. The number of titanium dioxide production enterprises decreased from 70 in 2000 to more than 40 in 2011.
——The overall level of industry technology has improved. The chlorination titanium dioxide plant of Jinzhou Ferroalloy Group has finally achieved continuous and stable production through years of continuous research, becoming the first large-scale chlorination titanium dioxide production enterprise with independent intellectual property rights in China. In the sulfuric acid process titanium dioxide production process, the optimization and adjustment of large-scale titanium slag instead of ilmenite production process, the use of large-scale acidolysis reactor and premixed acidolysis process, the popularization of vacuum crystallization instead of freezing process technology, and the wide application of large-scale hydrolysis reactor and operation technology have improved the production technology and product quality of titanium dioxide industry in China as a whole.
——The level of industry equipment is constantly improving. The titanium dioxide industry, while moving towards the large-scale plant, has constantly increased its investment in science and technology, vigorously carried out the technical transformation of the plant, and promoted the application of new processes, new technologies and new equipment. The overall equipment technology level of the industry has been rapidly improved. Large air swept mill replaces Raymond machine to crush ilmenite, vacuum crystallization tank replaces freezing crystallization tank for freezing, disk filter replaces centrifuge for ferrous separation, large acidolysis reactor with a volume of more than 100m3, large hydrolysis reactor, large rotary kiln, drying and utilization spray and flash equipment, etc. The use of a large number of new equipment and imported equipment has greatly improved the technical level of domestic titanium dioxide production equipment.
——The product quality has been greatly improved. In recent years, through independent development, introduction, digestion, absorption and re innovation and other means, enterprises in the titanium dioxide industry in China have greatly improved and developed the structure, quality and use of products produced in the whole industry. Special and special anatase titanium dioxide products have been continuously developed and mass produced. rutile titanium dioxide multi brand and multi-functional products have emerged, filling some gaps in the domestic titanium dioxide industry, Especially for the products produced by some large backbone production enterprises, the gap in quality and quantity with the world's advanced level is greatly narrowing, and some high-end products can completely replace imported products.
——The quantity and level of exports have improved. For a long time, the import volume of titanium dioxide in China was larger than the export volume, and until June 2010, the export volume was basically equal to the import volume. Due to the improvement of product quality, the number of the whole industry's exports to the international market is also increasing. In 2011, the import and export pattern of titanium dioxide in China changed substantially. On the basis of maintaining a stable import volume, the export volume rose all the way. The total export volume of titanium dioxide in the whole year reached 398000 tons, 174.2% of the import volume that year, making China a net exporter of titanium dioxide for the first time in history.
