Titanium dioxide industry opens the "Chinese era"

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 has nearly quadrupled and the beautiful landscape of the “Global Titanium Industry in China” has formed. Not only titanium dioxide production capacity and output have leapt to the top in the world, becoming the world's largest producer and consumer of titanium dioxide, and the entire titanium dioxide industry has made great progress in terms of production technology, product quality, and export structure.

The proportion in the world has increased dramatically. In recent years, the production capacity and output of titanium dioxide in China have grown rapidly, becoming the world's largest producer and output of titanium dioxide. Titanium dioxide production capacity was only 340,000 tons in 2000. It increased to 2.43 million tons in 2011, an increase of 7 times. The proportion of global production capacity jumped from 6.7% to over 20%; the production of titanium dioxide was only 290,000 tons in 2000. It will grow to 1.755 million tons by 2011, an increase of nearly 6 times. The growth rate is much higher than the world average. In particular, the growth rate of rutile products is even faster. From the annual output of 2.73 tons in 2000 to 1.176 million tons in 2011, the proportion of total titanium dioxide production has increased dramatically from 9.41%. To 67% or more, it is just 2/3 of the total production of titanium dioxide in the industry, and it is further close to the international 85% to 90% ratio.

The scale of the company and the degree of industry concentration have increased significantly. By the end of 2011, there were 40 TiO2 production enterprises in China with a production capacity of 10,000 tons/year or above, 8 medium-sized companies with 50,000 tons/year or more, and 3 large-scale enterprises with 100,000 tons/year or more. The number of titanium dioxide production enterprises has shrunk from 70 in 2000 to more than 40 in 2011.

The overall technical level of the industry has improved. Jinzhou Ferroalloy Group Titanium Dioxide Chlorination Plant has achieved continuous and stable production through continuous research for many years, becoming the first large-scale titanium dioxide production enterprise with independent intellectual property rights in China. In the sulfuric acid process titanium dioxide production process, the large-scale titanium slag to replace the ilmenite production process optimization and adjustment, the use of large-scale acid hydrolysis reactor and the pre-mixed acid hydrolysis process, the vacuum crystallization technology instead of popularization, large-scale hydrolysis The extensive application of reactors and operating technologies has improved the production technology and product quality of China's titanium dioxide industry as a whole.

The level of industry equipment continues to increase. Titanium Dioxide Industry has been increasing its investment in science and technology while continuing to increase the size of its devices. It has vigorously carried out technological transformations of the devices and promoted the use of new processes, technologies, and new equipment. The industry's overall equipment technology level has been rapidly improved. Large-scale wind-swept grinding machine replaces Raymond machine to disintegrate ilmenite, vacuum crystallization tank instead of frozen crystallization tank for freezing, disc filter instead of centrifuge for ferrous separation, large-scale acid hydrolysis reactor with volume over 100m3, large-scale hydrolysis Reactors, large rotary kiln, drying and spray and flash equipment, etc. The introduction of a large number of new equipment and imported equipment has greatly improved the technical level of domestic titanium dioxide production equipment.

Product quality has been greatly improved. In recent years, various enterprises in China's titanium dioxide industry have developed and introduced, digested, and re-innovated through various means. The products produced by the industry have been greatly improved in terms of structure, quality, and use. Special and special The anatase titanium dioxide products are continuously developed and mass-produced, and the multi-brand and multi-functional products of rutile titanium dioxide have come out one after another, filling some gaps in the domestic titanium dioxide industry, especially those produced by some large-scale backbone enterprises. The gap between quality and quantity and the advanced level in the world is greatly reduced, and some high-end products can completely replace imported products.

The number and level of exports have increased. All along, China’s imports of titanium dioxide exceeded exports, until June 2010 exports and imports were basically the same. Due to the improvement of product quality, the number of export-oriented international markets in the industry has also been increasing. In 2011, the import and export structure of titanium dioxide in China has undergone a fundamental change. On the basis of stable import volume, export volume has risen steadily throughout the year. The total amount of white powder exported reached 398,000 tons, which was 174.2% of the import volume of the year, making China a net exporter of titanium dioxide for the first time in history.

The adoption of strengthened Four-Layer steel belt protect the TBR Tire body from puncture, abrasion, explosion and distortion; with high rubber content; detailed in workmanship; special design of the strengthened bead toe without distortion and deformation, reduces the damage possibility in order to ensure good security and doubles the mileage.
