Titanium dioxide: a new step on the road to a strong country

China's titanium dioxide industry started in Shanghai Huaheng Chemical Plant, which was born in 1956
.

Although it was 40 years later than the world's first titanium dioxide factory built in Norway, after 65 years of development, under the leadership of the party, China's titanium dioxide industry came from behind.

In 1957, the Tianjin Research Institute of Chemical Industry of the Ministry of Chemical Industry organized a systematic research and development of pigment-grade anatase titanium dioxide production technology.
In 1958, some non-pigment-grade small titanium dioxide factories were established in Tianjin, Jinan, Wuxi and other places
.

From 1962 to 1963, Tianjin Research Institute of Chemical Industry expanded the test results of pigment-grade anatase titanium dioxide, conducted industrial trial production in Shanghai Huaheng Chemical Plant and Tianjin Tong Biochemical Plant, and passed the appraisal jointly organized by the Ministry of Chemical Industry and Shanghai Chemical Industry Bureau.

By the mid-1980s, many small titanium dioxide factories were built across the country.
108 enterprises were mainly concentrated in Henan, Guangxi, Jiangsu and other provinces, and most of them were township enterprises
.

These enterprises are not only small in scale, but also backward in technology and equipment, poor product quality, and serious pollution from the "three wastes"

In order to restrict the rush of titanium dioxide enterprises that do not have the production conditions, the Ministry of Chemical Industry formulated a policy in 1988 to prohibit the establishment of titanium dioxide enterprises with an annual size of less than 3,500 tons, and implemented a titanium dioxide production license system in 1991
.

When formulating the "Seventh Five-Year Plan", the Ministry of Chemical Industry put forward the development policy of "simultaneous development of both sulfuric acid and chlorination processes, simultaneous development of basic construction and technological transformation, simultaneous development of technology introduction and domestic technology development".
The white powder factory began to be built, and the introduction of technology also began to proceed in an orderly manner
.

Among them, the 404 plant of the Ministry of Nuclear Industry introduced the titanium dioxide process and engineering technology of the Czech Polycolor Company, and built a 15,000-ton/year sulfuric acid titanium dioxide plant in 1993; Sichuan Chongqing Yugang Titanium Dioxide Co.
, Ltd.
introduced Polish Politz titanium dioxide Factory technology and equipment, a 15,000-ton/year titanium dioxide plant was built in 1995; in 1994, Liaoning Jinzhou Ferroalloy Plant built China’s first 15,000-ton/year chlorination titanium dioxide plant
.

The digestion and absorption of imported projects has played a role in promoting the technological progress and large-scale installations of China's titanium dioxide industry

　　The substantial development of China's titanium dioxide industry began in 1998
.

According to Bi Sheng, director of the Titanium Dioxide Sub-center of the National Chemical Productivity Promotion Center and Secretary-General of the Titanium Dioxide Industry Technology Innovation Strategic Alliance, before the 1990s, there was no 10,000-ton titanium dioxide manufacturer in China.

　　Up to now, there are 12 large-scale enterprises in the national titanium dioxide industry with an annual output of 100,000 tons or more, followed by Lomon Baili, Panzhihua Vanadium Titanium, China Nuclear Titanium Dioxide, China National Chemical Corporation, Shandong Dongjia Group, and Jinpu Titanium Industry , Shandong Jinhai Titanium, Ningbo Xinfu, Shandong Daun Titanium, Guangxi Jinmao Titanium, Yunnan (Panzhihua) Dahutong and Panzhihua Titanium (Group)
.

At this stage, there are nearly 10 large-scale expansion projects under construction, with a total annual production capacity of about 1.

　　After more than 20 years of rapid development, China's titanium dioxide industry has also made great progress in terms of technology, product quality and industrial chain extension
.

　　In terms of new technologies and equipment, the acid hydrolysis tail gas treatment technology developed by Wuhan Fangyuan in recent years, the acid hydrolysis tail gas recovery and comprehensive utilization technology of Hubei Shengrong Environmental Protection and Energy Technology Co.
, Ltd.
, and the multi-effect titanium liquid concentration technology of Nantong Sansheng And equipment, Nanjing Huadian Energy Conservation and Environmental Protection Co.
, Ltd.
's rotary kiln exhaust waste heat utilization technology, Zhongyi Luyuan’s MVR low-temperature concentration technology, Guangdong Huiyun’s red gypsum high-pressure filter press dehydration equipment, sulfur, titanium, iron, and calcium co-production technology and The continuous acid hydrolysis technology has played a demonstrative role for the technological progress of China's titanium dioxide industry
.

　　In terms of industrial chain development, enterprises will gradually create conditions to take the road of co-production based on their own conditions and the characteristics of the surrounding environment, so as to realize the reduction and recycling development of resources
.

A large number of key enterprises such as Sichuan Dragon Mang, Shandong Dongjia, Shandong Daun, Qianjiang Fangyuan, Jiangxi Tianguang, etc.

　　The quality improvement of titanium dioxide products is also gradually accelerating
.

The quality of coatings and plastic special sulfuric acid rutile titanium dioxide of a large number of companies such as Lomon Baililian, Shandong Dongjia, Panzhihua Vanadium Titanium, Qianjiang Fangyuan has reached or approached the international first-line product level, and has been recognized by the high-end market, making China A new step has been taken on the road of titanium dioxide power
