Titanium dioxide is chemically stable, generally does not react with other substances, and is mainly divided into plate titanium dioxide, anatase titanium dioxide, rutile titanium dioxide. Titanium dioxide has a high market demand and is used in all major fields. Including: coatings, paper, plastics, control, ink, medicine and other industries.
Uses of Titanium dioxide:
Titanium dioxide is widely used in coating, 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. Paint made with titanium dioxide, bright colors, high hiding power, strong coloring power, dosage savings, variety, the stability of the medium can play a protective role, and can enhance the mechanical strength of the paint film and adhesion, to prevent cracks, to prevent ultraviolet rays and moisture transmission, to 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, weather resistance of plastic products, so that the physical and chemical properties of plastic products have been improved, enhance the mechanical strength of the products, and extend the service life.
Paper industry is the third largest user of titanium dioxide, as a paper filler, mainly used in high-grade paper and thin paper. Adding titanium dioxide in paper can make the paper with good whiteness, good gloss, high strength, thin and smooth, no penetration in printing, and light quality. Paper titanium dioxide is generally used without surface treatment of acute titanium 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 and heat resistance.
Titanium dioxide is also an indispensable white pigment in high-grade 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 is rutile and anatase.
Textile and chemical fiber industry is another important application of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Since anatase is softer than rutile, anatase is generally used. Chemical fiber with titanium dioxide generally do not need surface treatment, but some special varieties in order to reduce the photochemical effect of titanium dioxide, to avoid fiber degradation in the role of titanium dioxide photocatalysis, the need for surface treatment.
Titanium dioxide is used in the rubber industry both as a colorant and as a reinforcing, anti-aging and filling agent. Titanium dioxide is added to white and colored rubber products, which are resistant to sunlight, no cracking, no discoloration, large stretching rate and acid and alkali resistance under sunlight irradiation. Titanium dioxide for rubber, mainly used in automobile tires and rubber shoes, rubber flooring, gloves, sports equipment, etc., generally titanium-acute type. But for automobile tire production, often adding a certain amount of rutile products to enhance the ozone and UV resistance.
Titanium dioxide made of enamel transparency, with small quality, strong impact resistance, good mechanical properties, bright colors, not easy to contaminate and so on. Titanium dioxide for food and medicine is very high purity, low heavy metal content, strong hiding power of titanium dioxide.
