At present, the Group has more than 1200 valid patents, including 2 international valid patents. It has won more than 30 provincial and ministerial achievement evaluations, 1 Chinese patent award, and more than 30 scientific and technological progress awards at and above the provincial and ministerial level, including 4 first-class prizes and 10 second-class prizes. Presided over or participated in the compilation of more than 50 standards, including nearly 30 national standards. The company pioneered three green clean manufacturing technologies: sulfur-chlorine coupling, pyrite-titanium co-production and titanium-lithium coupling, breaking through the three "neck" technologies of upgrading chlorinated raw materials, large-scale boiling chlorination and preparation of rotor-grade sponge titanium for aviation.

The research and development of large-scale boiling chlorination technology has achieved four major innovative breakthroughs and reached international advanced. In view of the industry problems hindering the development of China's chlorinated titanium dioxide, such as the lack of high-quality titanium raw materials, the lack of core technology and equipment, the lack of high-end special titanium dioxide coating technology, and the difficult treatment of chlorinated waste, the complete set of technology development and industrialization projects for the manufacture and resource utilization of boiling chlorinated titanium dioxide developed by Longbai Group have successfully achieved four major technological innovation breakthroughs: the invention of titanium enrichment technology for multi-component and complex titanium concentrate. To solve the difficult problem in the preparation of low-cost boiling chlorination furnace material, and to ensure the safe and reliable supply of chlorination raw materials in China's titanium industry. Break through the key technologies of boiling chlorination and oxidation, independently design the first large-scale boiling chlorination furnace in China, take the lead in realizing the continuous and stable production of titanium dioxide by boiling chlorination, develop the graded dispersion of titanium dioxide base material and a series of high-end special titanium dioxide coating control technology, overcome the difficult problem of controlling the particle size and dispersion of titanium dioxide base material, and realize the import substitution of a series of high-end titanium dioxide. Develop the resource utilization technology of chlorination waste, improve the comprehensive utilization rate of titanium, carbon, vanadium, scandium, chlorine and other resources, and promote clean production in chlorination titanium dioxide industry.

The largest chlorination titanium dioxide production base in the country.

At present, the innovative achievements of the project have been transformed into new quality productive forces to promote the green development of enterprises. In recent years, the Group has invested hundreds of millions of yuan to build China's largest 450000 tons / year titanium-rich material, the world's largest 660000 tons / year high-end titanium dioxide production line and supporting chlorine-containing waste residue comprehensive utilization production system. The achievement is highly innovative, the overall technology has reached the international advanced level, and the main performance indicators of some products have reached the international leading level. This innovative technological achievement thoroughly solves the bottleneck of efficient and continuous production of domestic chlorinated titanium dioxide base material, and lays a solid foundation for the continuous production of high quality titanium dioxide.

Change the development pattern of titanium dioxide by chlorination process in China

Realize the green transformation and upgrading of titanium dioxide industry

The large-scale boiling chlorination project of Longbai Group has independent intellectual property rights, and the chlorination process titanium dioxide and its supporting production line run smoothly. At present, the group has two major chlorination production bases, Henan Bailian New Materials Company and Yunnan Lufeng Titanium Industry, and has a mature operation of multi-line production. The production capacity of chlorinated titanium dioxide has reached 660000 tons per year, and has rapidly developed into the world's number one titanium dioxide supplier with remarkable economic, social and environmental benefits. Compared with the traditional sulfuric acid method, the chlorination technology is more green and environmentally friendly, and its waste residue heap stock is more than 90% less than the sulfuric acid method, comprehensive energy saving is 30%, water saving is 50%, and the benefit is considerable.

Longbai Group takes the lead in the construction of Henan Titanium material Industry Innovation Center, carries out the research and development of strategic, forward-looking and key technologies and products with independent intellectual property rights, and strengthens the research on "choke neck" technology and key core technology. drive the transformation and upgrading of the industry.
