TiO2 Powder
TiO2 Powder Titanium dioxide powder (TiO2 powder CAS is an important inorganic chemical pigment powder, the main component of titanium dioxide. White powder, strong hiding power, good dispersion, narrow ion distribution, dry powder fluidity, TiO2 titanium dioxide has superior weather resistance and gloss, titanium dioxide powder production process has sulfuric acid method and chlorination method two process routes. Titanium dioxide pigment has important uses in coating, ink, paper making, plastic and rubber, chemical fiber, ceramics and other industries. Physical properties: Appearance and color: Titanium dioxide is usually a white powder with extremely high whiteness. It is the whitest of all white pigments and can give the product a good appearance and color. Particle size: The particle size and distribution have a significant impact on its performance. The appropriate particle size can make titanium dioxide have good hiding power and dispersibility. The average particle size is generally between 0.2-0.4μm. Oil absorption: refers to the mass of oil required for 100g of titanium dioxide to be completely wetted by oil. Low oil absorption is conducive to its use in coatings, plastics and other systems, reducing the amount of base material. The oil absorption of titanium dioxide rutile is generally 18-20g/100g, and the density of titanium dioxide anatase is about 18-24g/100g. Chemical properties: Chemical stability: Titanium dioxide has relatively stable chemical properties. At room temperature and pressure, it hardly reacts chemically with other substances. It has good acid and alkali resistance and can maintain a stable chemical structure and performance in general acid and alkali environments. Photochemical activity: Anatase titanium dioxide has certain photochemical activity under ultraviolet irradiation, and can produce free radicals, which may cause the degradation of organic matter around it. This feature needs to be controlled in some applications, but it has certain application value in the field of photocatalysis. Thermal stability: Rutile titanium dioxide has high thermal stability and can maintain the stability of its crystal structure and performance at high temperatures, which is suitable for some high-temperature processing applications. Handling and storage (safety related): Handling safety During production and use, it is necessary to prevent the formation of titanium dioxide dust, because long-term inhalation of titanium dioxide dust may have a certain impact on the respiratory system. Operators should wear personal protective equipment such as protective masks, protective glasses and gloves. If the skin comes into contact with titanium dioxide, rinse with plenty of water; if it accidentally enters the eyes, rinse immediately with plenty of running water and seek medical attention in time. Storage safety Titanium dioxide should be stored in a dry, well-ventilated warehouse to avoid moisture, because moisture may cause it to agglomerate and affect its performance. Keep away from fire and heat sources, and store separately from flammable, explosive items and other chemicals. Be careful when handling to prevent damage to the packaging. Safety of use When using titanium dioxide for production and processing, follow the relevant operating procedures and safety standards to ensure that it is used under appropriate conditions to give full play to its performance and ensure the safety of operators.
