titanium dioxide (titanium dioxide) is an important inorganic chemical pigment, the main component of titanium dioxide. The production process of titanium dioxide has two kinds of process routes: sulfuric acid method and chlorination method. It has important applications in coating, ink, paper making, plastic and rubber, chemical fiber, ceramics and other industries.

Avoid dust, sweep it up carefully, place it in a bag and transfer it to a safe place. If a large amount of leakage, with plastic sheet, canvas cover. Collect and recycle or transport to waste disposal site for disposal.
Application
The main application areas of titanium dioxide: coatings, plastics, ink, paper, of which coatings accounted for 60%, plastics accounted for 20%, paper accounted for 14%, other (including cosmetics, chemical fiber, electronics, ceramics, enamel, welding rod, alloy, glass and other fields) accounted for 6%.
Titanium dioxide in the rubber industry as a colorant, but also has a reinforcing, anti-aging, filling role. Titanium dioxide is added to white and colored rubber products, under sunlight, sun resistance, no cracking, no discoloration, large elongation and acid and alkali resistance. Rubber titanium dioxide, mainly used in automobile tires and rubber shoes, rubber floors, gloves, sports equipment, generally based on anatase. However, for the production of automobile tires, a certain amount of rutile type products are often added to enhance the anti-ozone and anti-ultraviolet ability.
Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic and far superior to lead white, almost all kinds of fragrance powders use titanium dioxide to replace lead white and zinc white. Only 5%-8% titanium dioxide can be added to the powder to get permanent white, so that the spice is more slippery, with adhesion, absorption and hiding power. Titanium dioxide in gouache and cold cream can reduce the feeling of greasy and transparent. Titanium dioxide can also be used in various other spices, sunscreens, saponins, white soaps and toothpastes.
First, cosmetic grade titanium dioxide is divided into oily and water-based titanium dioxide. Due to its stable chemical properties, high refractive index, high opacity, high hiding power, good whiteness, and non-toxic, it is widely used in the field of cosmetics, beauty whitening effect. [1] Performance characteristics: high whiteness, strong hiding power.
Hydrophilic, lipophilic products It overcomes the general titanium dioxide in the respective dispersion system is not easy to disperse, easy to precipitate and other defects, significantly improve its dispersion and precipitation resistance, make your product more stable and satisfactory.
Strong weather resistance.
Good compatibility with other raw materials of cosmetics.
[2] Uses titanium dioxide is considered to be the world's best performance of a white pigment, widely used in coatings, plastics, paper, printing ink, chemical fiber, rubber, cosmetics and other industries.
Titanium dioxide (titanium dioxide) is chemically stable and does not react with most substances under normal circumstances. There are three types of titanium dioxide crystals in nature: plate titanium, anatase and rutile. Plate titanium is an unstable crystal, no industrial use value, Anatase (Anatase) referred to as type A, and Rutile (Rutile) referred to as type R, all have a stable lattice, is an important white pigment and porcelain glaze, and other white pigments have superior whiteness, coloring power, covering power, weather resistance, heat resistance, and chemical stability. Especially not toxic.
Titanium dioxide is widely used in coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemical, medicine, food and other industries.
The paint industry is the largest user of titanium dioxide, especially rutile titanium dioxide, most of which is consumed by the paint industry. The paint made of titanium dioxide has bright color, high hiding power, strong coloring power, provincial amount, 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.
The plastics 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.
The 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 to the paper can make the paper have better whiteness, good luster, high strength, thin and smooth, not penetrate when printing, and light weight. Titanium dioxide for paper making generally uses anatase titanium dioxide without surface treatment, which can play the role of fluorescent whitening agent and 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 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.
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 is generally used because anatase is softer than gold red. Titanium dioxide for chemical fiber generally does not need surface treatment, but some special varieties need surface treatment in order to reduce the photochemical action of titanium dioxide and avoid the degradation of the fiber in the photocatalysis of titanium dioxide.
Enamel industry is an important application field of titanium dioxide, enamel grade titanium dioxide has high purity, good whiteness, fresh color, uniform particle size, strong refractive index and high achromatosity, with strong opacidity and opacity, so that the coating after enamelling is thin, smooth and strong acid resistance, in the enamel manufacturing process can be mixed evenly with other materials, no caking, easy melting and other advantages.
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, at 1200℃ high temperature conditions to maintain 1 hour unchanged ash characteristics. High opacity, thin coating, light weight, widely used in ceramics, architecture, decoration and other materials.
