Anatase titanium dioxide is the type of titanium dioxide mainly produced in China. One of the commonly used titanium dioxide is rutile titanium dioxide, but most of it is imported from abroad. Anatase titanium dioxide is mainly used in the coatings industry. Let's take a look at the manufacturing methods and uses of anatase titanium dioxide.
Anatase titanium dioxide production method:
According to the manufacturing process of titanium dioxide, there are currently sulfuric acid method and chlorination method, and both methods can produce type A and type R titanium dioxide. The sulfuric acid method started in 1931, and the chlorination method [2] began to produce type A in 1975. The oxidation step in the chloride method controls the particle size distribution and crystal structure, so that it can produce high hiding power and base color blue, high coloring. Strength of titanium dioxide. At present, the domestic anatase titanium dioxide is only produced by the sulfuric acid process, and the chlorination process is only used for the manufacture of some rutile titanium dioxide.
Anatase titanium dioxide use:
Widely used in coatings, plastics, paper, printing inks, rubber, cosmetics and other industries, textile and chemical fiber industry is another important application area of ​​anatase titanium dioxide. Non-coating titanium dioxide is also subdivided into enamel grade titanium dioxide, ceramic grade titanium dioxide, electronic ceramic grade titanium dioxide, electrode grade titanium dioxide, alloy grade titanium dioxide, glass grade titanium dioxide and other varieties.
