Overview: titanium dioxide naturally exists in titanium ores such as titanium ore and rutile. Its molecular structure makes it have high brightness and covering, but it must be chemically extracted and purified first. Compared with the old sulfuric acid process, the titanium dioxide production process by chlorination method can not only produce high-quality pigment products, but also reduce environmental emissions and energy consumption. At present, it has become the preferred technology in the world. Titanium dioxide (or TiO2) is the most widely used white pigment in industry, which is used in architectural, industrial and automotive coatings; Plastics for furniture, electrical appliances, plastic belts and plastic boxes; High grade magazines, brochures and paper with film, as well as special products such as ink, rubber, leather and elastomer.
Chemical properties: white powder.
Uses 1. Used in paint, ink, plastic, rubber, papermaking, chemical fiber and other industries.
Use 2. Edible white pigment; Compatibilizer. Silica and / or alumina are commonly used as dispersant additives.
Use 3. As food colorant
Use 4. White inorganic pigment. It is one of the most powerful white pigments with excellent hiding power and color fastness. It is suitable for opaque white products. Rutile type is especially suitable for outdoor plastic products, which can give products good light stability. Anatase is mainly used for indoor products, but it has a slight blue light, high whiteness, large hiding power, strong coloring power and good dispersion. Titanium dioxide is widely used as the pigment of paint, paper, rubber, plastic, enamel, glass, cosmetics, ink, watercolor and oil color. It can also be used in the manufacture of metallurgy, radio, ceramics and welding electrodes. In recent years, it has been found that nano-sized titanium dioxide has some special uses, such as sunscreen cosmetics, wood protection, food packaging materials, agricultural plastic films, natural and man-made fibers, transparent external durable topcoats and effect pigments, as well as additives for high-efficiency photocatalysts, adsorbents and solid lubricants.
Application 5. Used in paint, plastic, rubber and other industries
Purpose 6
1. Uniform particle size and good dispersion;
2. It basically has no scattering effect on incident visible light, has strong ultraviolet shielding ability and excellent transparency, and has been widely used in cosmetics, coatings, paints and other products as a new material;
3. used in plastic, rubber and functional fiber products, it can improve the anti-aging ability, anti powdering ability, weatherability and product strength of products, while maintaining the color luster of products and prolonging the service life of products.
4. applied to ink, coating and textile, it can improve adhesion, anti-aging and scrubbing properties. 5. It is lipophilic and can be well dispersed in organic solvents and plastic resins;
6. Used in paper industry to improve printability and impermeability;
7. It can also be applied to metallurgical and aerospace industries.
