Titanium dioxide is also increasingly widely used in cosmetics. Due to the non-toxic nature of titanium dioxide, which is far superior to lead white, almost all types of fragrance powders use titanium dioxide instead of lead white and zinc white. Simply add 5% -8% titanium dioxide to the fragrance powder to obtain a permanent white color, making the fragrance smoother, with adhesion, absorption, and covering power. Titanium dioxide powder can reduce the feeling of greasy and transparent in water powder and cold cream. Titanium dioxide can also be used in various other spices, sunscreen, soap, white soap, and toothpaste. Porcelain glazes made from titanium dioxide have strong transparency, low quality, strong impact resistance, good mechanical properties, bright colors, and are not easily contaminated. Titanium dioxide used in food and medicine is a type of titanium dioxide with high purity, low heavy metal content, and strong covering power. Widely used in industries such as coatings, plastics, papermaking, printing inks, chemical fibers, rubber, cosmetics, etc.
Titanium dioxide has stable chemical properties and generally does not react with most substances. In nature, titanium dioxide has three kinds of crystals: plate titanium, anatase and Rutile. The plate titanium type is an unstable crystal type, which has no industrial use value. Anatase is referred to as type A, and rutile is referred to as type R. Both have stable lattice, and are important white pigments and porcelain glazes. Compared with other white pigments, it has superior whiteness, coloring power, hiding power, weather resistance, heat resistance, and chemical stability, especially no toxicity.
Titanium dioxide is widely used in industries such as coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, pharmaceuticals, food, etc.
The coating industry is a major user of titanium dioxide, especially Rutile titanium dioxide, which is mostly consumed by the coating industry. Coatings made of titanium dioxide have bright colors, high covering power, strong coloring power, low dosage, and a wide variety. They can protect the stability of the medium, enhance the mechanical strength and adhesion of the paint film, prevent cracks, prevent UV and water penetration, and extend the lifespan of the paint film.
The plastic 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 their physical and chemical properties, enhance their mechanical strength, and extend their service life.
The paper industry is the third largest user of titanium dioxide powder, mainly used as a paper filler in high-end and thin paper. Adding titanium dioxide to the paper can make it have good whiteness, good luster, high strength, thin and smooth, non penetrating during printing, and light weight. Titanium dioxide for paper making generally uses anatase titanium dioxide without surface treatment, which can act as a Optical brightener and increase the whiteness of paper. However, the laminated paper requires the use of Rutile titanium dioxide with surface treatment to meet the requirements of light resistance and heat resistance.
Titanium dioxide is also an indispensable white pigment in advanced ink. Ink containing titanium dioxide is durable and does not change color, has good surface wettability, and is easy to disperse. Titanium dioxide used in the ink industry includes Rutile and anatase.
The textile and chemical fiber industries are another important application field of titanium dioxide. Titanium dioxide used in chemical fibers is mainly used as a matting agent. Due to the fact that the anatase type is softer than the gold red type, the anatase type is generally used. Titanium dioxide powder for chemical fiber generally does not require surface treatment, but some special varieties require surface treatment to reduce the photochemical effect of titanium dioxide and avoid fiber degradation under the photocatalytic effect of titanium dioxide.
