Titanium dioxide can form several different shapes, which have different properties. Some shapes can be converted to nanomaterials. Micronized TiO2 (also called “nano” or “nanoparticles”) was introduced in the early 1990s. Nanotechnology and micronization both refer to the practice of creating very small particles sizes of a given material. “Nanoparticles” usually refers to particles smaller than 100 nanometers; a nanometer is 1/1 billionth of a meter. At these small sizes, and at low concentrations, titanium dioxide appears transparent, allowing for effective sunscreens that do not appear white.
It offers several advantages in various applications. Its excellent opacity and brightness make it a popular choice in the production of paints, coatings, and printing inks, providing a cost-effective alternative to titanium dioxide. Lithopone's chemical stability enhances its durability in outdoor environments, making it suitable for outdoor coatings. Additionally, its low reactivity and compatibility with other pigments contribute to its versatility. Beyond coatings, lithopone finds utility in plastics, rubber, and paper industries. Overall, its multifaceted advantages and broad applications underscore this compound's significance in diverse industrial sectors.
Below 10% substitution, 1 kg of TiO2 should be replaced by 1 kg of Lithopone 30%.
Overwhelmingly, research that’s relevant to human eating patterns shows us that E171 is safe when ingested normally through foods and drugs (1,2).
One of the key challenges facing TiO2 industry suppliers is the fluctuation of raw material prices. The production of TiO2 requires raw materials such as ilmenite or rutile, which are subject to market price volatility. Suppliers must carefully monitor these fluctuations and adjust their production processes accordingly to ensure profitability.
As a food additive, titanium dioxide and its nanoparticles in particular have been associated with DNA damage and cell mutations, which in turn, have potential to cause cancer. When used as a food coloring, it is known as E171.
- Needle Roller Bearings: Needle roller bearings feature cylindrical rollers with a much smaller diameter-to-length ratio compared to cylindrical rollers. This design allows for a higher load-carrying capacity in a compact space, making needle roller bearings suitable for applications with limited radial space.
For example, in automotive engines, these bearings help to reduce friction and heat generation, leading to improved fuel efficiency and reduced emissions For example, in automotive engines, these bearings help to reduce friction and heat generation, leading to improved fuel efficiency and reduced emissions6002 ball bearing.In summary, the key difference between spherical roller bearings and cylindrical roller bearings lies in their design, load-carrying capabilities, and suitability for specific applications. Each type of bearing is tailored to meet distinct operational requirements and environmental conditions in diverse industrial applications.
