Titanium dioxide is chemically stable, generally does not react with other substances. It contains plate titanium dioxide, anatase titanium dioxide and rutile titanium dioxide. It has a high market demand and wild application in all major fields, including coatings, paper, plastics, prevention and control, ink, medicine and other industries. Below is a detailed description for you.
Applications of titanium dioxide:
Titanium dioxide has a wide application in coating, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, medicine, food and other industries.
1. Coating Industry
Coating industry is the largest consumer of titanium dioxide, especially rutile titanium dioxide, most of which is consumed by the coating industry. The paint made of titanium dioxide has bright color, high hiding power, strong coloring power, low and many varieties, which can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film, prevent cracks, prevent ultraviolet light and water penetration, and extend the life of the paint film.
2. Plastics Industry
Paper 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 the service life.
3. Paper Industry
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 anatasegrade 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 grade titanium dioxide to meet the requirements of light and heat resistance.
4. Ink Industry
Titanium dioxide is also an indispensable white pigment in advanced 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 has rutile type and anatase type.
5. Textile & Fiber Industry
The textile and chemical fiber industries are another important application area for titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Anatase titanium dioxide is generally used because anatase type is softer than rutile type. Titanium dioxide for chemical fiber generally does not need surface treatment, but some special varieties need surface treatment in order to reduce the photochemical effect of titanium dioxide and avoid the degradation of the fiber in the photocatalysis of titanium dioxide.
6. Rubber Industry
Titanium dioxide has a wide application in the rubber industry both as a colorant and as a reinforcing, anti-aging and filling agent. It is added to white and colored rubber products, which are resistant to sunlight, with 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 anatase grade titanium dioxide. But for the production of automobile tires, people often add a certain amount of rutile products to enhance the ozone and ultraviolet resistance.
7. Cosmetics Industry
Titanium dioxide also has an increasingly wide application in cosmetics. Because titanium dioxide is non-toxic, far superior to lead whiteand zinc white, almost all kinds of perfume powder use titanium dioxide to replace lead white and zinc white. Perfume powder only need to add 5% -8% of the titanium dioxide can get permanent white, and the perfume become more slippery with adhesion, absorption and covering power. In watercolour and cold cream, titanium dioxide can weaken the greasy and transparent feeling. In addition, titanium dioxide can also be used in various other fragrances, sunscreen, soap flakes, white soap and toothpaste, etc.
8. Other Industry
Moreover, the glaze made of titanium dioxide has strong transparency, small quality, strong impact resistance, good mechanical properties, bright color, and is not easy to be polluted. And the titanium dioxide for food and medicine has high purity, low heavy metal content and strong hiding power.
