Titanium dioxide is also called titanium dioxide, and its chemical formula is: TiO2, which is chemically stable and does not react with most substances under normal conditions. Titanium dioxide is widely used.
1. Titanium dioxide is applied in cosmetics
Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic, it is far superior to lead white. Almost all kinds of powders use titanium dioxide instead of lead white and zinc white. Only 5%-8% of titanium dioxide is added to the powder to obtain a permanent white color, which makes the fragrance more slippery, with adhesion, absorption and hiding power. Titanium dioxide in gouache and cold cream can reduce the feeling of greasy and transparent. Titanium dioxide is also used in various other fragrances, sunscreens, soaps, white soaps and toothpastes.
Cosmetic grade titanium dioxide is classified into oily and aqueous titanium dioxide. Because of its stable chemical properties, high refractive index, high opacity, high hiding power, good whiteness and no toxicity, it is widely used in the field of cosmetics, and it has the effect of beauty and whitening.
2. Titanium dioxide application in coatings
Titanium dioxide for coatings is divided into two types: anatase and rutile. The structures of anatase titanium white and rutile titanium white are used in different places. Anatase titanium dioxide is used for interior wall coatings because it is easy to be pulverized, and rutile is often used for exterior wall coatings because of its resistance to aging. They all have a stable crystal lattice and are important white pigments and porcelain glazes. They have superior whiteness, tinting strength, hiding power, weather resistance, heat resistance, and chemical stability compared with other white pigments, especially no toxicity. .
3. Titanium dioxide screening
Screening mesh: 40-325 mesh or even finer;
Material characteristics: white crystal or white crystalline powder, easy to block the net, easy to absorb moisture.
4. Solution and advantage analysis
Since the choice of vibrating screen should contain many factors such as: particle size structure, specific gravity, water content, viscosity, temperature, disposal amount, etc., titanium dioxide white powder can choose the following models:
1. Rotating vibrating screen (low output and high precision)
2. linear vibrating sieve (Capacity is not as accurate as the vibrating screen)
3. Ultrasonic vibrating screen
