The first nationwide boiling chlorination process titanium dioxide production technology conference and the Luohe Xingmao titanium industry chlorination titanium dioxide engineering technology review meeting were held last week in Luohe City, Henan Province. A number of titanium dioxide experts discussed and evaluated the production technology of the boiling chlorination process titanium dioxide of Luohe Xingmao Titanium Industry Co., Ltd. The expert group believes that the company has completely mastered the chlorinated titanium dioxide production process technology system, has independent independent intellectual property rights, and the product quality has reached the advanced level of similar products at home and abroad, and is basically stable. The project has reached the leading domestic and international advanced level. According to Li Maoen, chairman of Xingmao Titanium Industry Co., Ltd., the chlorination process titanium dioxide production project has a total construction scale of 200,000 tons/year, the first-phase construction scale is 60,000 tons/year, and actual investment funds are 750 million yuan. Products by the National Coatings Quality Supervision and Inspection Center testing, whiteness, hue, achromatic power, hiding power, paint film performance, paint film gloss, dispersion and other indicators have reached the international advanced quality standards of similar products. At present, the project is transferred to the normal production stage, and the production system operation and product quality are stable. It is understood that the primary particle size of titanium dioxide is one of the key factors that determine its performance. At present, there is no titanium dioxide product with comparable particle size and particle size distribution that can be compared with similar products in the world. According to the analysis and analysis of the authoritative testing organizations of titanium dioxide products, Luohe Xingmao Titanium can produce products with excellent primary particle size in the current titanium dioxide industry in China. It has the potential for product quality to fully meet or even exceed the potential for the import of chlorinated titanium dioxide. Product impurities The elements of the composition were commissioned by the international authority of the Swiss General Survey (SGS). All tests were in line with the relevant professional limits of the European Union. Heavy metal elements were not detected. Li Maoen told the China Chemical Daily that the first phase of the project entered the phase of comprehensive construction in March 2012. The first production line construction was completed in August 2013, and trial production began in September 2013. By September 2014, the pilot production of the project realized the entire process. Continuous continuous full-load operation for 99 hours. The continuous and stable operation of the completion and production of the project indicates that the Luohe Xingmao Titanium Industry has completely mastered the construction and production technology of the titanium chloride chlorite project; the successful long-term operation of the project not only broke the domestic technical bottleneck, but also cultivated a number of outstanding Technical talents. The company also has the basic conditions for further enlargement and strengthening. Xingmao Titanium will keep an eye on the forefront of the world's science and technology, establish a strong technical R&D team, and build a world-class chlorination process titanium dioxide project. The National Titanium Dioxide Expert Group stated that the project was completed by the enterprise on its own strength, and achieved continuous operation success from project construction to trial production, and transferred to normal and stable production. It has reasonable technology, advanced technology, stable operation, and safety and reliability. Features. The success of the trial production of this project marked a major breakthrough in the production technology of chlorinated titanium dioxide representing the upgrading of China's titanium dioxide industry and the adjustment of industrial structure, which is conducive to breaking the blockade and monopoly of foreign technologies. News link Titanium dioxide is the third largest inorganic chemical product in the world, which is next only to synthetic ammonia and phosphoric acid. It is widely used in coatings, plastics, paper, chemical fiber, ink and other fields. Asia is the main demand area for titanium dioxide worldwide, and the titanium dioxide industry is showing rapid growth. In 2013, the actual production of titanium dioxide in China exceeded 2 million tons for the first time, reaching 2.155 million tons, an increase of 14%, accounting for about one-third of the global total. It has exceeded the United States for several years in a row, and is the world’s largest producer of titanium dioxide. And consumer countries. Industry experts predict that the annual demand for titanium dioxide in China will maintain an increase of 10% to 15%, and with the acceleration of domestic urbanization, the growth trend will be even stronger. From the point of view of production technology, the world's titanium dioxide production mainly has two kinds of sulfuric acid and chlorination technologies. Among them, the chlorinated titanium dioxide production technology has developed rapidly due to its remarkable advantages such as short process flow, large production capacity, high product quality, and low pollution emission, and it is a very mature advanced technology in the world. Since the 1980s, foreign The new titanium dioxide production line adopts this process as the mainstream production line. At present, about 60% of titanium dioxide production worldwide is produced using the chlorination process. For a long time, foreign chemical giants have imposed a high degree of blockade and monopolization on the chlorination of titanium dioxide production technology. The current domestic design capacity of sulfuric acid titanium dioxide has reached an annual output of 2.8 million tons or more, of which about 2 million tons of capacity was built in the past decade, And distributed in dozens of manufacturers. The enterprises are mostly small and medium-sized enterprises, the industry concentration is obviously too low, the products are mainly low-end, and the homogenization competition is fierce. The demand for high-end products still depends on imports, and the annual import volume is about 200,000 tons. expert's point Promote chlorination, technology is the key Due to the advantages of short process flow, large production capacity, high degree of automation, good product quality, low secondary waste discharge, and clean production, the chlorination process has become the main trend of global titanium dioxide process development. Except for China, none of the new titanium dioxide plants in the world since the 1980s used the sulfuric acid method, and the original sulfuric acid plant was gradually eliminated due to environmental and economic reasons. In the United States, the world's largest producer of titanium dioxide, the sulfuric acid plant was closed in the 1990s, and the world’s largest manufacturer of titanium dioxide, DuPont, produced nearly 1.2 million tons of annual production capacity, all of which are chlorinated processes. The production capacity has reached 450,000 tons/year. In China, there is a world of difference. The total national capacity of titanium dioxide was less than 200,000 tons/year in 1998. After more than ten years of rapid development, the total production capacity has surpassed that of the United States in 2012 and it has become the new world's first. In 2013, the total production capacity of titanium dioxide in China has reached 2.8 million tons/year. Only the Jinzhou Titanium industry, which normally produces chlorination process technology, has only less than 1.1% of the national total production capacity and actual output. The chlorination titanium dioxide production process represents the direction of the domestic titanium dioxide industry upgrade. Although China has listed chlorination as an encouragement category in the “Guidance Catalogue for Industrial Structure Adjustment†since 2005, the situation has been so bleak in the past 10 years that the development of chlorination titanium dioxide industry has been very difficult. Due to foreign monopolies, the lack of core technologies is the primary issue for the development of chlorination titanium dioxide projects in China. Chlorination titanium raw materials chlorination process, there are two kinds of molten salt process and boiling process. At present, only the Jinzhou titanium industry in the global chlorination titanium dioxide plant uses molten salt chlorination and subsequent oxidation to make titanium dioxide. Although molten salt chlorination has some advantages, it is more difficult to overcome. The chlorination by boiling has become the mainstream process in the production of titanium dioxide in the chlorination process in the world today. At present, the domestic boiling chlorination process titanium dioxide plant in trial production includes Jinzhou Titanium Industry 30,000 tons/year, Yunnan Xinli 60,000 tons/year and Luohe Xingmao's 60,000 tons/year first-phase project, followed up. Henan Lili 60,000 tons/year project. Among them, the Luohe Xingmao titanium industry has developed rapidly, and it has now entered the scale of normal production. This will play a positive role in the development of domestic chlorination titanium dioxide industry. Ningbo DOKEE Medical Technology Co., Ltd. , https://www.dokeemedical.com
