Breakthrough in large-scale titanium dioxide technology

August 11, the Ministry of scientific and technological achievements appraisal meeting held in Beijing, the Group of Luohe simexco shares of the company independently developed "30,000 tons / year chloride process titanium dioxide production engineering technology" for the identification of scientific and technological achievements
.
The appraisal committee believes that the project has overcome many technical and equipment problems in the production of titanium dioxide by the chloride process, broke through the long-term monopoly of foreign related technologies, formed a complete production line, and achieved continuous and stable production up to standards
.
The project technology has reached the domestic leading and international advanced level
.

Bi Sheng, chairman of the Appraisal Committee, director of the Titanium Dioxide Sub-center of the National Chemical Industry Productivity Promotion Center, and secretary-general of the Titanium Dioxide Industry Technology Innovation Strategic Alliance, said that the stable operation of the project indicates that China has mastered the internationally advanced production technology of titanium dioxide chloride.
, Will play an active role in demonstrating the domestic titanium dioxide enterprises
.
The project research has improved the technical equipment level and product quality of China's titanium dioxide industry.
It is of great significance to the supply-side structural reform, technology and product upgrading, energy conservation and environmental protection of the domestic titanium dioxide industry, and has broad prospects for promotion and application.

.

It is understood that the chlorination process has become the mainstream production process of the international titanium dioxide industry due to its short process flow, large production capacity, high product quality, and low pollution emissions, accounting for 63% to 65% of the global total production capacity (excluding China)
.
However, for a long time, the international chemical giants have a high degree of monopoly on the production technology of chlorinated titanium dioxide.
The use of advanced chlorination process to replace sulfuric acid process has become the unanimous voice of all parties, and has also become the main direction of the transformation and upgrading of the domestic titanium dioxide industry
.

　　According to reports, the project adopts boiling chlorination gas-phase oxidation technology, and has developed boiling chlorination technology, titanium tetrachloride purification technology, gas-phase oxidation technology, oxidation reactor and rock salt scar removal technology.
The process selection is reasonable and the technology is advanced.
16 technical patents, with domestic independent intellectual property rights
.

　　The product of the project has been tested and verified by national CMA titanium dioxide application testing third-party laboratories such as the National Coating Quality Supervision and Inspection Center, Zhenjiang Fanhua Testing Technology Co.
, Ltd.
and other testing institutions, peer manufacturers and some customers such as coatings, plastics, and paper, indicating the overall product The quality level is better than that of the domestic industry, and the main basic quality indicators and the main application performance in water-based and solvent-based coatings and PVC plastics have reached or even partly exceeded the quality standards of international first-class products
.
In particular, the product's quality indicators such as dispersion, hiding power, and whiteness completely meet or are slightly better than internationally renowned brand products, and the quality level is very stable
.

　　In addition, through the inspection of the Guangzhou Branch of the Swiss Standards Technical Service Company, the various harmful elements in the product, cadmium, lead, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers, all meet the limit value requirements of the EU RoHS directive.
It can completely replace imported high-end products in general-purpose applications
.

　　Li Maoen, chairman of Luohe Xingmao Titanium Industry Company, said that the company will continue to increase its investment in core technology research and development in the next step.
Scientific research units in the United Nations will tackle new technologies and new equipment for 100,000 tons/year chlorination titanium dioxide, and realize domestic chlorination as soon as possible.
The breakthrough of French titanium dioxide large-capacity equipment technology has raised the level of national industry
