Nano-titanium dioxide is a white loose powder with strong UV shielding effect, good dispersion and weather resistance. It can be used in cosmetics, functional fibers, plastics, coatings, paints and other fields, as ultraviolet shielding agent, to prevent ultraviolet damage. It can also be used in high-grade automotive topcoat with angular heterochromic effect.
There are two main crystalline forms of nano-titanium dioxide: anatase and rutile. Rutile titanium dioxide is more stable and dense than anatase titanium dioxide. It has higher hardness, density, dielectric constant and refractive index, and its covering power and coloring power are also higher. The reflectance of anatase titanium dioxide in visible short wave region is higher than rutile titanium dioxide with blue hue, and the absorption ability of ultraviolet rays is lower than rutile type, and the photocatalytic activity is higher than rutile type. Under certain conditions, anatase titanium dioxide can be converted into rutile titanium dioxide.
Nanometer titanium dioxide, also known as titanium dioxide. The diameter of the product is less than 100 nanometers, and the appearance of the product is white loose powder. It can be used in cosmetics, functional fibers, plastics, inks, coatings, paints, fine ceramics and other fields.
In view of the above functions, nano-titanium dioxide has very broad prospects. The research and utilization of it will bring great changes to people's lives.
