The reporter learned from the recent training class for the third national titanium dioxide production technology held in Jiujiang, Jiangxi Province that the technological level of China's titanium dioxide industry has been continuously improved in recent years. China has become the most vigorously developing country in the world in the titanium dioxide industry, and it is only The second largest titanium dioxide producer in the world after the United States.
It is reported that in 2006, of the total 860,000 tons of titanium dioxide in the country, rutile products exceeded 300,000 tons for the first time, an increase of 80,000 tons over the previous two years. In addition to the improvement of product grades, China's titanium dioxide industry is also worthy of advancement in terms of technological progress: in terms of production technology, autogenous seed atmospheric pressure hydrolysis technology, external seed crystal atmospheric hydrolysis technology and external seed micro-pressure hydrolysis technology have been It has become a more advanced hydrolysis process in the industry; conventional surface treatment agents represented by aluminum and silicon, together with a new surface treatment agent represented by zirconium, have been treated with dense envelopes instead of loose porous envelopes for surface treatment to develop high weather resistance. Rutile products have added new technological approaches; the application of some new organic materials to the surface coating of titanium dioxide can improve the dispersion performance of the product.
At present, the internationally advanced technology and equipment technology has basically been popularized and applied in China's titanium dioxide industry. Some domestic product quality indicators have reached the international advanced level, and the industry has thus created a brand product with stable quality and good market effects.
