The hottest titanium dioxide industry opens the Ch

  • Detail

Since the beginning of the 21st century, China's titanium dioxide industry has entered a period of rapid integration and all-round development. The annual consumption of titanium dioxide in inland China has nearly quadrupled, forming a beautiful landscape of "China's era of global titanium dioxide industry". Not only has the production capacity and output of titanium dioxide jumped to the first in the world, becoming the largest production and consumption country of titanium dioxide in the world, but also the whole titanium dioxide industry has made great progress in production technology, product quality, export pattern and so on

-- its proportion in the world has increased significantly. 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. Titanium dioxide production capacity, only 340000 tons in 2000, increased to 2.43 million tons in 2011, an increase of 7 times, accounting for more than 20% of the global production capacity from 6.7%; The output of titanium dioxide was only 290000 tons in 2000, and increased to 1755000 tons in 2011, an increase of nearly 6 times. The growth rate is much higher than the world average, especially the rutile products, which 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%, accounting for 2/3 of the total output of titanium dioxide in the whole industry, further approaching the international proportion range of 85% - 90%

-- the enterprise scale and industry concentration have increased significantly. By the end of 2011, there were 40 titanium dioxide production enterprises with an output of more than 10000 tons/year, 8 medium-sized enterprises with an output of more than 50000 tons/year, and 3 large-scale enterprises with an output of more than 100000 tons/year. The number of titanium dioxide production enterprises decreased from 70 in 2000 to more than 40 in 2011

-- the overall technical level of the industry has been improved. Through years of continuous research, the chlorination titanium dioxide plant of Jinzhou Ferroalloy Group has finally achieved continuous and stable production, and has become the first large-scale chlorination titanium dioxide production enterprise with independent intellectual property rights in China. In the production process of titanium dioxide by sulfuric acid method, 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 China's titanium dioxide industry as a whole

-- the equipment level of the industry continues to improve. While the titanium dioxide industry is moving towards large-scale devices, it continues to increase investment in science and technology, vigorously carry out the technical transformation of devices, and promote the application of new processes, new technologies, and new equipment. The overall equipment and technology level of the industry has been rapidly improved. The large-scale wind swept mill replaces Raymond machine to crush ilmenite, the vacuum crystallization tank replaces the freezing crystallization tank for freezing, that is, from the main production of gasoline and diesel oil to the main hope to help everyone. We need to provide raw materials for ethylene/aromatics, the disk filter replaces the centrifuge for ferrous separation, large acidolysis reactors with a volume of more than 100m3, large hydrolysis reactors, large rotary kilns, drying and utilization spray and flash equipment, etc. A large number of new equipment and imported equipment have been put into use, which 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 and introduction, digestion, absorption and re innovation, enterprises in China's titanium dioxide industry have greatly improved and developed the products produced in the whole industry in terms of structure, quality and use of moving samples to ensure that the temperature of samples is within the allowable temperature range. Special and special anatase titanium dioxide products have been continuously developed and mass produced, and rutile titanium dioxide is multi brand The advent of multi-functional products has filled some gaps in the domestic titanium dioxide industry, especially the products produced by some large backbone production enterprises. The gap with the world's advanced level in quality and quantity is greatly narrowed, and some high-end products can completely replace imported products

-- the number and level of exports have been improved. For a long time, the import volume of titanium dioxide in China has been greater than the export volume. Until June, 2010, the export volume and import volume were basically the same. Due to the improvement of product quality, the number of exports of the whole industry 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 of that year, making China a net exporter of titanium dioxide for the first time in history
