Uses of rutile titanium dioxide
Titanium dioxide is considered the world's best white pigment, widely used in coatings, plastics, papermaking, printing inks, chemical fibers, rubber, cosmetics and other industries.
Titanium dioxide is considered the best white pigment in the world, widely used in coatings, plastics, papermaking, printing inks, chemical fibers, rubber, cosmetics and other industries.
Titanium dioxide (titanium dioxide) is chemically stable and does not react with most substances under normal conditions. In nature, titanium dioxide has three crystal forms: brookite, anatase, and rutile. Brookite is an unstable crystal form with no industrial value. Anatase (Anatase), abbreviated as A-type, and rutile (Rutile), abbreviated as R-type, both have stable lattices and are important white pigments and porcelain glazes. Compared with other white pigments, they have superior whiteness, tinting strength, hiding power, weather resistance, heat resistance, and chemical stability, especially non-toxicity.
Titanium dioxide is widely used in coatings, plastics, rubber, inks, paper, chemical fibers, ceramics, daily chemicals, medicine, food and other industries.
The coatings industry is the largest consumer of titanium dioxide, especially rutile titanium dioxide, most of which is consumed by the coatings industry. Coatings made with titanium dioxide have bright colors, high hiding power, strong tinting strength, low consumption, and a wide variety of types. They can protect the medium, enhance the mechanical strength and adhesion of the paint film, prevent cracking, prevent ultraviolet light and water penetration, and prolong 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 products, and extend their service life.
The papermaking 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 paper can make the paper have better whiteness, good gloss, high strength, thin and smooth, non-penetrating during printing, and light weight. Generally, untreated anatase titanium dioxide is used for papermaking, which can act as an optical brightener to increase the whiteness of the 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 high-grade inks. Inks containing titanium dioxide are durable and do not change color, have good surface wettability, and are easy to disperse. The titanium dioxide used in the ink industry includes both rutile and anatase types.
The textile and chemical fiber industry is another important application area for titanium dioxide. Titanium dioxide for chemical fibers is mainly used as a matting agent. Because anatase is softer than rutile, anatase is generally used. Titanium dioxide for chemical fibers generally does not require surface treatment, but for some special varieties, in order to reduce the photochemical effect of titanium dioxide and avoid the degradation of fibers due to the photocatalytic effect of titanium dioxide, surface treatment is required.
