Overview of titanium oxide TiO2 powder:
Titanium oxide TiO2 powder, also called titanium dioxide, is an important inorganic chemical pigment, mainly composed of titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method. It is widely used in coatings, printing inks, papermaking, plastics and rubber, chemical fiber, ceramics, and other industries.
Among the commonly used white pigments, titanium dioxide has the smallest relative density, and among white pigments of the same quality, titanium dioxide has the largest surface area and the largest pigment volume. Titanium dioxide has very stable chemical properties and is an acidic amphoteric oxide. At room temperature, it hardly reacts with other elements and compounds. It is ineffective against oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, and sulfur dioxide. It is insoluble in water, fat, dilute acid, and inorganic acid, alkali, and only soluble in hydrofluoric acid. . But under the action of light, titanium dioxide can undergo continuous REDOX reaction and has photochemical activity. Under the action of ultraviolet anatase titanium dioxide, this photochemical activity is particularly obvious.
Titanium dioxide has two structures: rutile (rutile R type) and anatase (A type). The rutile crystal structure is compact, relatively stable, and has low optical activity, so it has good weather resistance, high hiding power, and color matting. Titanium dioxide has semiconductor properties, its conductivity increases rapidly with temperature, and it is also very sensitive to hypoxia. The dielectric constant and semiconductor properties of rutile TiO2 are very important to the electronics industry and can be used to produce electronic components, such as ceramic capacitors.
According to the Mos hardness level of 10 points, rutile TiO2 is 6 to 6.5, and anatase TiO2 is 5.5 to 6.0. Therefore, in chemical fiber matting, anatase is used to avoid abrasion of the spinneret holes. Although titanium dioxide is hydrophilic, its hygroscopicity is not too strong, and the rutile type is smaller than the anatase type. The hygroscopicity of titanium dioxide has a certain relationship with its surface area, large surface area, and high hygroscopicity, but it is also related to surface treatment and performance.
Application of titanium oxide TiO2 powder:
What is the scope of application of titanium dioxide TiO2 powder?
The most important applications of titanium dioxide are paints, varnishes and paper, and plastics, which account for about 80% of the world's consumption of titanium dioxide. Other pigment applications, such as printing inks, fibers, rubber, cosmetics, and food, account for another 8%. The rest is used for other applications, such as industrial pure titanium, glass and glass ceramics, electroceramics, metallic copper, catalysts, electrical conductors, and chemical intermediates.
1. Titanium dioxide has become the most widely used white pigment due to its brightness and high refractive index.
2. Titanium dioxide is also an effective sunscreen in powder form. It is used as a pigment to provide whiteness and opacity to products such as paints, coatings, plastics, paper, inks, foods, medicines (such as tablets and tablets), and most toothpaste. In painting, it is usually abbreviated as "lively white", "completely white", "whitest white" or other similar terms.
3. Titanium dioxide is used as a coloring agent in the rubber industry, and it also has the functions of reinforcement, anti-aging, and filling.
4. Adding titanium dioxide to white and colored rubber products, in the sun, it is resistant to sunlight, does not crack, does not change color, stretch magnification and acid and alkali resistance.
5. Titanium dioxide for rubber is mainly used in car tires, rubber shoes, rubber floors, gloves, sports equipment, etc., generally anatase type.
6. For the production of automobile tires, a certain amount of rutile titanium dioxide products are often added to enhance the ability to resist ozone and ultraviolet rays.
7. Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic and far superior to lead white, almost all powdered titanium dioxide can replace lead and zinc white.
8. Only 5%-8% of titanium dioxide powder can be added to the permanent white color to make the fragrance smoother, strong in adhesion, absorption, and covering power.
9. Titanium dioxide in gouache and cold cream can reduce greasiness and transparency.
10. Titanium dioxide can also be used in many other spices, sunscreens, soaps, white soaps, and toothpaste.
11. When deposited as a thin film, the refractive index and color of titanium dioxide make it an excellent reflective optical coating for dielectric mirrors.
12. Certain grades of modified titanium-based pigments are used in foam paints, plastics, topcoats and cosmetics-the particles of these artificial pigments have two or more layers of different oxides (usually titanium dioxide, iron oxide, or oxide). Aluminum), which can produce flash, iridescent, and/or pearlescent effects.
13. Titanium dioxide is used as a pigment, sunscreen, and thickener in cosmetics and skincare products in sunscreens and UV protection pigments.
14. As a sunscreen, it uses ultra-fine TiO2, which is known for its combination with ultra-fine zinc oxide. It is considered an effective sunscreen, which can reduce the incidence of sunburn and minimize the effects associated with long-term use. Early photoaging, photocarcinogenesis, and immunosuppressive sun exposure. Excess semester. Sometimes these UV protectors are used in sunscreens with iron oxide pigments to enhance the protection of visible light.
