The main use of titanium dioxide (titanium dioxide)

Titanium dioxide is a white pigment whose main component is titanium dioxide. Therefore, the use of titanium dioxide is mainly discussed through the use of titanium dioxide. Titanium dioxide is a substance with excellent thermal stability and is an acidic amphoteric oxide. But it has photochemical activity. It is not very hygroscopic and has three crystal forms in nature: rutile, anatase and titanium.

What are the uses of titanium dioxide, and what is the main purpose of titanium dioxide?

1. Coating: The coating is a viscous suspension composed of a binder, a pigment, a solvent and an auxiliary agent. Titanium dioxide is used as a pigment in coatings. The pigment has the function of covering and decorating to achieve the decorative appearance. At the same time, the pigment can enhance the mechanical strength and adhesion of the film and prolong the service life of the film.

2, plastic: titanium dioxide in the application of plastic products, in addition to its high hiding power, high achromatic power and its pigment properties, it can also improve the heat resistance, light resistance, weather resistance of plastic products, so that plastic products are free Infected by UV light to improve the mechanical and electrical properties of plastic products.

3. Ink: The white pigments used in the ink manufacturing industry are mainly titanium white powder and zinc white. Among them, titanium dioxide not only has good physical and chemical stability, but also has good resistance to various kinds of materials, and has lower prices than other ink materials.

4, paper: paper using titanium dioxide, whiteness, high strength, shiny, thin and smooth, does not penetrate during printing, under the same conditions, opacity is 10 times higher than calcium carbonate, talcum powder, weight can also be reduced 15%~30%. Therefore, decorative paper, Bible paper and banknotes must use titanium dioxide.

5. Rubber: Titanium dioxide is used as a coloring agent in the rubber industry, and has the functions of reinforcing, anti-aging and filling. Mainly used in automobile tires and rubber shoes, rubber flooring, gloves, sports equipment, etc., generally based on anatase.

6, cosmetics: titanium dioxide is non-toxic, almost all kinds of powder used to replace lead white and zinc white. Titanium dioxide in gouache and cold cream can reduce the feeling of greasy and transparent. Titanium dioxide is also used in various other fragrances, sunscreens, soaps, white soaps and toothpastes.
