What is titanium dioxide?

Titanium dioxide is a natural mineral extracted, processed, or refined from the Earth, and added to various foods and other consumer goods. White is used to enhance the color and luster of certain foods, and is also crucial for food safety applications. It is ground into very fine powder during the processing. Titanium dioxide is safe, and the FDA provides strict guidance on its usage in food. The amount of food grade titanium dioxide is extremely low; The FDA stipulates that the content of titanium dioxide in food shall not exceed 1%. There is currently no indication of health risks associated with dietary intake at this level.

Overview of titanium dioxide TiO2 powder

Titanium dioxide, also known as TiO2 powder, is an important inorganic chemical pigment, mainly composed of titanium dioxide. There are two production processes for titanium dioxide: sulfuric acid method and chloride method. Widely used in industries such as coatings, printing inks, papermaking, plastic rubber, chemical fibers, ceramics, etc.

Among commonly used white pigments, titanium dioxide has the smallest relative density, while among white pigments of the same quality, titanium dioxide has the largest surface area and pigment volume. Titanium dioxide has very stable chemical properties and is an acidic zwitterionic oxide. At room temperature, it hardly reacts with other elements and compounds. Invalid for oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, and sulfur dioxide. Insoluble in water, fats, dilute acids, and inorganic acids and bases, only soluble in hydrofluoric acid.. But under the action of light, titanium dioxide can undergo continuous redox reactions and has photochemical activity. Under the action of ultraviolet rutile type titanium dioxide, this photochemical activity is particularly evident.

Titanium dioxide has two types of structures: rutile type (Rutile type R type) and anatase type (A type). The crystal structure of rutile is dense, relatively stable, and has low optical rotation, therefore it has good weather resistance, high covering power, and extinction. Titanium dioxide has semiconductor properties, its conductivity increases rapidly with increasing temperature, and it is also very sensitive to hypoxia. The dielectric constant and semiconductor properties of rutile type TiO2 are very important for the electronic industry and can be used in the production of electronic components, such as ceramic capacitors.

According to the Mos hardness level of 10, the rutile type TiO2 is 6-6.5, and the rutile type TiO2 is 5.5-6.0. Therefore, rutile is used in the chemical fiber felt to avoid wear of the spinneret holes. Although titanium dioxide has hydrophilicity, its moisture absorption is not very strong, and the rutile type is smaller than the rutile type. The hygroscopicity of titanium dioxide is related to its surface area. Although it has a large surface area and high hygroscopicity, it is also related to surface treatment and performance.

Application of titanium dioxide TiO2 powder

The most important applications of titanium dioxide are paint, varnish, paper, and plastics, which account for approximately 80% of the world's titanium dioxide consumption. Other pigment applications, such as printing ink, fiber, rubber, cosmetics, and food, account for an additional 8%. The rest are used for other applications, such as industrial pure titanium, glass and glass ceramics, electroceramics, metallic copper, catalysts, electroconductors, 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 powder sunscreen. It is used as a pigment to provide whiteness and opacity for products such as paints, coatings, plastics, paper, inks, food, pharmaceuticals (such as tablets and tablets), and most toothpaste. In painting, it is usually abbreviated as "lively white", "complete white", "whitest white" or other similar terms.

3. Titanium dioxide is used as colorant in rubber industry, and also has the functions of reinforcement, anti-aging and filling.

4. Titanium dioxide is added to white and colored rubber products, which are resistant to sunlight, do not crack, do not change color, have a high tensile strength, and are acid and alkali resistant.

5. Titanium dioxide for rubber is mainly used in automotive tires, rubber shoes, rubber flooring, gloves, sports equipment, etc. It is generally of the sharp titanium type.

6. In the production of automotive tires, a certain amount of rutile titanium dioxide products are often added to enhance their resistance to ozone and ultraviolet radiation.
