Application of titanium dioxide in the coating industry
In all applications of pigment titanium dioxide, the amount of coating is the largest. Titanium dioxide is widely used in coatings, such as buildings, automobiles, ships, furniture, household appliances, coil coating, toys and daily necessities. In the coating industry, architectural coatings consume the most titanium dioxide, followed by coatings for automobiles, ships, railway vehicles and furniture. Because rutile titanium dioxide has better performance than anatase titanium dioxide, rutile titanium dioxide is selected as high weatherability coating for outdoor use of ships, bridges, automobiles, buildings and so on. At present, rutile titanium dioxide has exceeded that of titanium dioxide used in coatings. With the development of China's automobile industry and construction industry, the coating industry not only needs more titanium dioxide in quantity, but also has higher requirements for variety and quality.
Application of titanium dioxide in the papermaking industry
Titanium dioxide is mainly used as filler in the paper industry. Titanium dioxide for papermaking generally uses anatase titanium dioxide without surface treatment, which can play the role of fluorescent brightener and increase the whiteness of the paper. However, the laminated paper requires the use of rutile titanium dioxide with a surface treatment to meet the requirements of light resistance and heat resistance. Because titanium dioxide has a high refractive index and achromatic power, adding titanium dioxide to the pulp can make the paper have better whiteness, higher opacity, good gloss, high strength, thin and smooth, nonpenetration during printing, and lightweight.
Application of titanium dioxide in the ink industry
Titanium dioxide has the characteristics of good whiteness, small and uniform particle size, high refractive index, high coloring power and hiding power, good physical and chemical stability, light diffusion, light resistance, heat resistance, weather resistance and hydrophobicity, which make titania not only an indispensable white pigment in ink manufacturing, but also a necessary raw material for blending many intermediate color ink products. The ink containing titanium dioxide is durable, does not change color, has good surface wettability, and is easy to disperse. Titania used in the ink industry has rutile type and anatase type.
