Chloride process titanium dioxide Development Analysis

At present,the domestic titanium dioxide factory showing a low excess capacity.The majority of the plant has an annual capacity of less than 50,000 tons, annual production capacity of thousands of the country only three.Especially in contrast with the imports of titanium dioxide quality aspects,basic non-dominant.

Foreign titanium dioxide experienced more than a hundred years of development,there are DuPont,the U.S. Millennium Ventnor has a leading position in the global factory,while domestic decades of development,the national small factories hundreds of mixed quality,the continuous development of the process of the titanium dioxide industry,the demise of the part of the small factory,2012, titanium dioxide industry in the country,small businesses have closed due to environmental and other factors in the basic production of 6 to 7,the existing normal production process type scale more than 49.

In domestic and foreign titanium dioxide contrast Production gap exists abroad,mostly chlorination,while the domestic scale and can be produced by chlorination plant as long as the Jinzhou Titanium Industry Development of a chlorination become a focus of domestic concern,and now a number of national factories try to chlorination.Only in 2012,Henan Billions will buy American PPG and Germany chlorination of titanium Kang,before titanium Kang,buyer Yunnan Xinli, after two years of development,can take advantage of late envelope technology, conduct sulfuric acid method rutile crude processing,full chlorination production, perhaps in the near future,at the same time,the Luohe simexco chlorination factory has been built,the staff is stationed.Not only sulfate process titanium dioxide plant innovative attempt to chlorination,Jinzhou Titanium is also constantly improve themselves,to expand production capacity production,enhance product quality.

National Chemical Industry Productivity Center titanium dioxide sub-director of the Center for Bi Sheng pointed out that the current around the chloride process titanium dioxide in the construction and implementation of the project a total of six. According to China National Coatings Industry Association branch chairman of the titanium dioxide industry,Xie Xiangyun expected that by 2015,a total of titanium dioxide production capacity will increase to 3.4 million tons,of which the chloride process titanium dioxide production capacity will reach 30 million metric tons.

Short process of chlorination device,the 'three wastes' emissions,small footprint,good quality products at home and abroad are willing to develop the technology.But China the domestic catch on the development of the chlorination process at the same time,we have to ask the short term really in the country developed it?

Since the violations in February 2012,the domestic production of titanium dioxide chloride process technology has become a more sensitive topic,for pre-technology research,as well as the actual production of the chloride process titanium dioxide,there is doubt.February 2012 late Ventnor (Tronox) CEO Tom?titanium dioxide Enterprise recently by the case of titanium dioxide intellectual property theft, Casey said,the construction chloride process titanium dioxide facilities more difficult. He said that the construction chlorination equipment require complex technology and involves the issue of intellectual property rights,and thus,over the past few years,China has not yet constructed a new chloride process titanium dioxide plant. DuPont titanium dioxide intellectual property theft case with Chinese factories,it also shows that China's considerable interest in this technology,but still significantly less than its own built confidence.

Chlorination production late simply understood rinsing,grinding,drying,coated for domestic sulfuric acid method factory basic difficulties,technical difficulty,and previous experience in domestic factories can be overcome,but the production of pre-chlorinated part,is not optimistic.To DuPont,for example,its success point is,can take advantage of the low-quality titanium concentrates to produce high quality titanium dioxide,the key lies in the part of the pre-production of chlorinated.

To gain more market share,the chloride process titanium dioxide production in the future is bound to an increasingly popular topic,walked the streets of foreign titanium dioxide hundred years development,domestic have once again set foot after experiencing difficulties,hope You can see the early local new chloride process titanium dioxide.
