Titanium dioxide is an important inorganic chemical pigment, and its main component is titanium dioxide. There are two production processes of titanium dioxide: sulfuric acid method and chlorination method, which have important applications in coatings, inks, paper making, plastics and rubber, chemical fiber, ceramics and other industries.
Titanium dioxide is considered as a kind of white pigment with the best performance in the world, which is widely used in industries such as coatings, plastics, paper making, printing ink, chemical fiber, rubber and cosmetics.
The coating industry is the main use of titanium dioxide, especially rutile titanium dioxide, which is mostly consumed by the coating industry. The paint made of titanium dioxide has bright colors, high hiding power and strong coloring power, which can protect the stability of media, enhance the mechanical strength and adhesion of paint film, prevent cracks, prevent ultraviolet rays and moisture from penetrating, and prolong the life of paint film.
The plastics industry is the second largest application. Adding titanium dioxide to plastics can improve the heat resistance, light resistance and weather resistance of plastic products, improve the physical and chemical properties of plastic products, enhance the mechanical strength of products and prolong their service life.
Paper industry is the third largest user of titanium dioxide. Adding titanium dioxide to paper can make paper have better whiteness, good luster, high strength, thin and smooth, non-penetrating when printing and light weight.
Titanium dioxide is also an indispensable white pigment in advanced inks. The ink containing titanium dioxide is durable, non-discoloring, good in surface wettability and easy to disperse.
Textile and chemical fiber industry is another important application field of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as matting agent.
Ceramic industry is also an important application field of titanium dioxide. Ceramic titanium dioxide has high purity, uniform particle size, high refractive index and excellent high temperature resistance. High opacity, thin coating and light weight are widely used in ceramics, architecture, decoration and other materials.
