Titanium dioxide is an important fine chemical raw material, the chemical composition of titanium dioxide, which is a white inorganic pigment with a wide range of applications and a large market demand.
Titanium dioxide is an important fine chemical raw material, the chemical composition of titanium dioxide, which is widely used in a wide range of applications. It is a major application field of white inorganic pigment titanium dioxide: coatings, plastics, inks, papermaking, of which coatings account for 60%. %, plastics accounted for 20%, papermaking accounted for 14%, and other (including cosmetics, chemical fiber, electronics, ceramics, enamel, welding rods, alloys, glass, etc.) accounted for 6%.
Titanium dioxide products are divided into two categories: one is rutile titanium dioxide, which is light-resistant and weather-resistant, and is mostly used for the production of outdoor coatings and products; the other is anatase titanium dioxide, which is lighter than rutile. For the production of interior coatings and products. Titanium dioxide is widely used in coatings, plastics, paper, ink, pharmaceuticals, fiber, cosmetics and other fields for its excellent performance.
The coatings industry is the largest user of titanium dioxide, especially rutile titanium dioxide, which is mostly consumed by the coatings industry. The coating made of titanium dioxide has bright color, high hiding power, strong coloring power, low dosage and variety, can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the film to prevent cracks. Prevents the passage of UV rays and moisture and prolongs the life of the 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 prolong 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 gloss, high strength, thin and smooth, no penetration during printing, and light weight. Titanium dioxide for papermaking generally uses an anatase-type titanium dioxide which has not been surface-treated, and can function as a fluorescent whitening agent to increase the whiteness of the paper. However, laminated paper requires the use of surface treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
Titanium dioxide is used as a coloring agent in the rubber industry, but also has reinforcing, anti-aging and filling effects. Titanium dioxide is added to white and colored rubber products. It is resistant to sunlight, sun cracking, no discoloration, high elongation and acid and alkali resistance under sunlight. Titanium dioxide for rubber, mainly used in automobile tires and rubber shoes, rubber flooring, gloves, sports equipment, etc., generally based on anatase. However, for the production of automobile tires, a certain amount of rutile type product is often added to enhance the anti-ozone and anti-ultraviolet ability.
Titanium dioxide is also an indispensable white pigment in advanced inks. The ink containing titanium dioxide is durable, does not change color, has good surface wettability, and is easy to disperse. Titanium dioxide used in the ink industry has a rutile type and an anatase type.
