Ten Uses Of Titanium Dioxide Detailed Explanation

Titanium dioxide is a kind of inorganic substance, chemical formula TiO₂, white solid or powdered amphoteric oxide, molecular weight 79.9, with non-toxic, the best opacity, the best whiteness and brightness, is considered to be the world's best performance of a white pigment. Titanium dioxide is also very widely used in our lives, follow the small series together to have a look.
Coating industry
Coatings are the most used in all applications of titanium white pigments. Paint is a kind of viscous suspension composed of base material, pigment, filler, solvent and auxiliaries. It can not only cover and decorate, but also improve the physical and chemical properties of the paint film, enhance chemical stability, to increase the hiding power, achromatic power, corrosion resistance, light resistance, weather resistance, enhance the mechanical strength and adhesion of the paint film, prevent cracking, prevent the passage of ultraviolet light and water penetration, so as to extend the life of the paint film.
Plastics industry
The plastics industry is the second largest user of titanium dioxide, and in order to make plastics have beautiful colors, a certain amount of color is often added to plastics. The addition of titanium dioxide in the processing process is easy to color and disperse, and does not react chemically with other components in the plastic. And improve the heat resistance, light resistance, weather resistance of plastic products, improve the physical and chemical properties of plastic products, enhance the mechanical strength of products, extend the service life.
Fiber industry
Titanium dioxide is mainly used as a matting agent in the chemical fiber industry, with high refractive index, strong coloring power, large hiding power, good dispersion, high whiteness, fine and uniform particles, good chemical stability, not easy to change, does not affect the tension and dyeing of the fiber, and good light resistance and weather resistance, is an excellent matting agent.
Paper industry
Titanium dioxide is mainly used as a filler in the paper industry, because it has refractive index and achromatic power, so the addition of titanium dioxide in the pulp can make the paper good whiteness, high transparency, good gloss, high strength, thin and smooth, impenetrable, light weight.
Rubber industry
In the rubber industry, titanium dioxide can be used as a colorant, but also as a filler, anti-aging, acid and alkali resistance, reinforcement. Titanium dioxide is added to white and light rubber products, so that the products have the characteristics of slow aging, high strength, no cracking, no fading, good ductility, acid and alkali resistance. Mainly used in automobile tires and rubber shoes, rubber floor, gloves, sports equipment and other rubber products.
Cosmetics industry
Because titanium dioxide can reflect and scatter ultraviolet light, stable chemical properties, non-toxic, good dispersion, smooth, strong adhesion to the skin, soft and uniform texture, fine particles, narrow particle size distribution, high whiteness, high achromism and hiding ability, is an important white raw material in the cosmetics industry.
Food, medical industry
The use of opaque titanium dioxide can improve the decorative effect of food and drugs. In addition to excellent pigment properties, titanium dioxide for food and medicine has very strict requirements for purity and harmful impurity content.
Electronics industry
In the electronics industry, titanium dioxide is one of the important raw materials for the manufacture of capacitors, piezoelectric ceramics, transparent electro-optical ceramics and other electronic components. Because titanium dioxide for electronic ceramics requires fine particles, large specific surface area, good resistance to reduction, high dielectric constant and resistance, high purity, and less impurities, it is generally used in capacitors or reagents in the electronics industry.
Wastewater treatment
As a durable photocatalyst, titanium dioxide has been used to treat dye wastewater, pesticide wastewater, surfactant wastewater, oil-containing wastewater, papermaking wastewater and so on. Used for a variety of environmental treatment problems, such as antibacterial, deodorization, heavy metal ion treatment, waste gas treatment, air purification, catalytic decomposition of water, etc.
Solar cell
Nanometer titanium dioxide is widely used in dye sensitization, quantum dots and perovskite solar cells because of its suitable band gap, good photochemical stability and simple production process.
