Application
Titanium dioxide is an important inorganic chemical pigment, mainly composed of titanium dioxide. The production process of all ATR series titanium dioxide is using sulfuric acid method. It has important applications in industries such as coatings, inks, papermaking, plastics and rubber, chemical fibers, ceramics, etc.
Its advantages over other types of titanium dioxide include:
1. Higher refractive index: Rutile titanium dioxide has a higher refractive index, which means it provides better hiding power and opacity.
2. Better weather resistance: Rutile titanium dioxide is resistant to weathering, which means it retains its color and properties for a longer time when exposed to sunlight, moisture, and other environmental factors.
3. Higher brightness and whiteness: Rutile titanium dioxide has a bright and white appearance, making it ideal for applications where a high degree of whiteness is required, such as in paper and coatings.
4. Superior tinting strength: Rutile titanium dioxide has a high tinting strength, which means it can produce a greater color intensity when mixed with other pigments or dyes.
5. Good stability and compatibility: Rutile titanium dioxide is chemically stable and compatible with other materials, including polymers, resins, and solvents, making it easy to incorporate into various formulations and manufacturing processes.
Titanium dioxide is commonly used in a wide range of industries and applications. Some of its primary applications include:
1. Pigment: Titanium dioxide is widely used as a white pigment in paints, coatings, plastics, inks, and paper, due to its opacity, brightness, and whiteness.
2. Sunscreen: Titanium dioxide is used as a UV-absorbing agent in sunscreens and other personal care products, as it helps to protect the skin from harmful UV rays.
3. Food additive: Titanium dioxide is used as a food additive in some countries, where it is used as a whitening agent, and as a thickening or anti-caking agent in certain foods.
4. Coatings and surface treatments: Titanium dioxide is used to improve the scratch resistance, durability, and other properties of coatings and surface treatments in various industrial applications.
5. Catalyst: Titanium dioxide is used as a catalyst in the chemical and petrochemical industries, for example, in the production of hydrogen from water using sunlight as a sustainable energy source.
6. Medical: Titanium dioxide is used in certain medical implants, such as dental implants and joint replacements, as it is biocompatible and has a low risk of allergic reactions.
7. Water treatment: Titanium dioxide is used as a photocatalyst in water treatment applications, where it helps to remove harmful contaminants and pollutants from water.
