Yuan Lei's Little Knowledge | Application Fields of Titanium Dioxide

Titanium dioxide scientific name for titanium dioxide (Titanium Dioxide), it is a dye and pigment, its molecular formula for TiO2, molecular weight of 79.8658.

Titanium dioxide is the most important white pigment, with high refractive index, good chemical stability, weather resistance, whiteness, high achromatic power and hiding power, and non-toxic harmless, no stimulation to the human body, widely used in coatings, plastics, paper, printing ink, medicine, fiber, cosmetics and other fields.

Application areas

[Coating]]:Coatings are viscous suspensions composed of binders, pigments, solvents and additives. Titanium dioxide is used as a pigment in paints. The pigment has the ability to cover and decorate, so as to achieve the function of decorative beauty. At the same time, the pigment can also enhance the mechanical strength and adhesion of the coating film, which can extend the service life of the coating film.

[Plastic]]:The plastics industry is the second largest user of titanium dioxide, and the consumption of titanium dioxide in the plastic field usually accounts for 20% of the consumption of titanium dioxide applications. The application of titanium dioxide in plastic products, in addition to the use of its high hiding power, high achromatic power and other pigment properties, it can improve the heat resistance, light resistance, weather resistance of plastic products, so that plastic products from the invasion of ultraviolet light, improve the mechanical and electrical properties of plastic products.

【Paper]: As a paper filler, mainly used in fine paper and thin paper. Adding titanium dioxide to the paper can make the paper have good whiteness, good gloss, high strength, thin and smooth, non-penetrating when printing, and light in quality. Paper with titanium dioxide is generally used without surface treatment of anatase titanium dioxide, can play the role of fluorescent whitening agent, 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.

ink]：White powder is also an indispensable white pigment in advanced ink. The ink containing titanium dioxide is durable and does not change color, the surface wettability is good, and it is easy to disperse. The titanium dioxide used in the ink industry has rutile type and anatase type.

[Ceramic]]:The ceramic industry is also an important application field of titanium dioxide. Ceramic grade titanium dioxide has high purity, uniform particle size, high refractive index, excellent high temperature resistance, and the characteristics of maintaining no ash for 1 hour at 1200 ℃. High opacity, thin coating, light weight, widely used in ceramics, construction, decoration and other materials.
