"Under the government's favorable policy of encouraging the development of the chlorination process and limiting the sulfuric acid process, there has been no substantial breakthrough in the development of the chlorination process titanium white process in the past decade or more." Bi Sheng, Director, National Titanium Dioxide Center for Chemical Productivity Promotion Center In an interview this week, he said that the appearance of this situation has both the obstacles to the monopoly of foreign companies and the factors that are difficult to develop independently. "Overall, long development and dispersal of power are the main reasons for this passive situation."
Bi Sheng told reporters that since the 1960s and 70s of last century, China began to research and develop chlorination technology in Xiamen and Tianjin, but there has been no substantial breakthrough. Until the 1990s, Liaoning Jinzhou Titanium Industry Co., Ltd. built a 15,000 tons/year chlorination plant through technical consultation and joint design. After more than a decade of technological research and improvement, the quality of chlorinated products has improved significantly compared to the previous year. However, the core oxidation technology and equipment materials still face constraints, and there are still some gaps with foreign large companies.
In addition to Jinzhou Titanium Industry, East China University of Science and Technology, Chinese Academy of Sciences Institute of Process, Panzhihua Iron and Steel Research Institute and other units have also done a lot of research work in the development of chlorination titanium dioxide technology, but have not yet seen the report of industrial production. Bi Sheng pointed out: "Unfortunately, independent technological development is not effective, and foreign advanced technology is difficult to introduce, China's titanium dioxide industry is facing greater difficulties in transitioning to the chlorination process. At present, domestic companies use favorable national policies to plan chlorination. In law projects, we should be prepared for the technical constraints and difficulties in the operation process."
Bi Sheng believes that based on the actual development of the titanium dioxide industry, the most effective way to promote the chlorination process in China should be the gradual improvement of technology and scale on the basis of the Jinzhou titanium industry. In the near future, efforts will be made to achieve a leap from 15,000 tons/year to 30,000 tons/year to 60,000 tons/year or even more. In this process, we should continuously improve product quality, improve surface treatment technology, narrow the gap with foreign advanced level, and strive to enter the high-end market, while achieving better economic benefits.
“The chlorination process titanium dioxide is a highly technically-intensive industry. All scientific innovation and technological advancement must be verified through the final industrial production practice.†He said that for the titanium dioxide industry in China, the chlorination process is undoubtedly an industry. The main direction of future development, but this process is difficult to achieve overnight. In the next 5 to 10 years, the domestic titanium dioxide industry will no longer be dominated by the sulfuric acid method, but the overall situation will be the sulfuric acid method and the chlorination method.
