Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method. It has important applications in coatings, inks, papermaking, plastics and rubber, chemical fiber, ceramics and other industries.

  Titanium dioxide is considered to be the best white pigment in the world. It is widely used in coatings, plastics, papermaking, printing inks, chemical fiber, rubber, cosmetics and other industries.
  Titanium dioxide (titanium dioxide) is chemically stable and does not react with most substances under normal circumstances. In nature, titanium dioxide has three crystals: brookite, anatase and rutile. The brookite type is an unstable crystal type and has no industrial use value. Anatase is abbreviated as A type, and Rutile is abbreviated as R type. Both have a stable crystal lattice and are important white pigments and porcelain glazes. Compared with other white pigments, it has superior whiteness, tinting power, hiding power, weather resistance, heat resistance, and chemical stability, especially non-toxic.
  Titanium dioxide is widely used in coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, medicine, food and other industries.
  The coating industry is the largest user of titanium dioxide, especially rutile titanium dioxide, most of which is consumed by the coating industry. The paint made of titanium dioxide has bright colors, high hiding power, strong tinting power, low dosage, and many varieties. It can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film to prevent cracks. Prevent the penetration of ultraviolet rays and moisture, and extend the life of the paint film.
  The plastics industry is the second largest user. 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 the products, and extend the service life.
  The paper industry is the third largest user of titanium dioxide. As a paper filler, it is mainly used in high-grade paper and thin paper. Adding titanium dioxide to the paper can make the paper have better whiteness, good gloss, high strength, thin and smooth, no penetration during printing, and light weight. Titanium dioxide for papermaking generally uses anatase titanium dioxide without surface treatment, which can act as a fluorescent whitening agent and increase the whiteness of paper. However, laminated paper requires the use of surface-treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
  Titanium dioxide is also an indispensable white pigment in advanced inks. The ink containing titanium dioxide is durable and does not change color, has good surface wettability and is easy to disperse. The titanium dioxide used in the ink industry has rutile type and anatase type.
  The textile and chemical fiber industry is another important application field of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Since the anatase type is softer than the gold red type, the anatase type is generally used. Titanium dioxide for chemical fiber generally does not require surface treatment, but in order to reduce the photochemical effect of titanium dioxide and prevent the fiber from degrading under the action of titanium dioxide photocatalysis, surface treatment is required for some special varieties.
  The enamel industry is an important application field of titanium dioxide. The enamel grade titanium dioxide has high purity, good whiteness, fresh color, uniform particle size, strong refractive index and high color reducing power, and has strong turbidity and Opacity, make the coating thin, smooth and strong acid resistance after enamelling. It can be evenly mixed with other materials in the enamel manufacturing process, does not agglomerate, and is easy to melt.
  The ceramic industry is also an important application field of titanium dioxide. Ceramic grade titanium dioxide has the characteristics of high purity, uniform particle size, high refractive index, excellent high temperature resistance, and no ash when kept at a high temperature of 1200°C for 1 hour. High opacity, thin coating, light weight, widely used in ceramics, construction, decoration and other materials.
