Performance and preparation of titanium dioxide

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.

The performance of titanium dioxide

Titanium dioxide is a white solid powder with the chemical formula TiO2. It has high light reflectivity and chemical stability, and is widely used in various fields. Titanium dioxide is divided into rutile type and rutile type according to its molecular structure. The rutile type has high light reflectivity and photocatalytic activity, while the rutile type has good thermal and chemical stability.

Preparation of titanium dioxide

The preparation methods of titanium dioxide mainly include gas-phase method, liquid-phase method, and solid-phase method. Among them, gas-phase method is the most commonly used preparation method, which generates titanium dioxide by reacting titanium powder with oxygen at high temperature. The liquid phase method is to prepare titanium dioxide from titanium salt solution by hydrolysis, precipitation or sol gel method. The solid-phase rule is to mix titanium powder with an oxidant and heat it to produce titanium dioxide.

Application of titanium dioxide TiO2 powder

What are the application ranges of titanium dioxide TiO2 powder?

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.

7. Titanium dioxide is also widely used in cosmetics. Due to its non-toxic nature and superior performance over lead white, almost all powdered titanium dioxide can replace lead zinc white.

8. Just add 5% -8% titanium dioxide to achieve a permanent white color, making the aroma smoother, with strong adhesion, absorption, and coverage.

9. The titanium dioxide in watercolor paintings and frosts can reduce greasiness and transparency.

10. Titanium dioxide can also be used in many other spices, sunscreen, soap, white soap, and toothpaste.

When deposited as a thin film, the refractive index and color of titanium dioxide make it an excellent reflective optical coating for dielectric electron microscopy.

12. Certain grades of modified titanium based pigments are used in foam coatings, 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 can produce sparkling, rainbow, and/or pearl like effects.

13. Titanium dioxide is used as a pigment, sunscreen, and thickener in cosmetics and skincare products, as well as in sunscreen and anti UV pigments.

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 that can reduce the incidence of sunburn and minimize the impact of long-term use. Early photoaging, photocarcinogenesis, and immunosuppressive sunlight exposure. Excess semester. Sometimes, these UV protectants are used together with iron oxide pigments in sunscreen to enhance protection against visible light.
