Industrial application of titanium dioxide


titanium dioxide is an important white pigment and porcelain glaze. Used in paints, inks, plastics, rubber, paper, chemical fiber, watercolor paints and other industries.


titanium dioxide is the whitest thing in the world, and 1 gram of titanium dioxide can coat more than 450 square centimeters of snow. It is five times whiter than the commonly used white pigment, zinc white, so it is the best pigment for white paint. Titanium dioxide used as a pigment in the world, from more than a few hundred thousand tons a year. Titanium dioxide can be added to paper to make the paper white and opaque, and the effect is 10 times larger than other materials. Therefore, titanium dioxide is added to banknote paper and art paper.


In order to lighten the color of the plastic and make the rayon soft, it is sometimes necessary to add titanium dioxide.

In the rubber industry, titanium dioxide is also used as a filler for white rubber.


The photochemical properties of semiconductor titanium dioxide have made it useful in many applications such as the purification of air, water and fluids. Photocatalysts doped with carbon or other heteroatoms can also be used in sealed spaces or regions with scattering sources.


When used in paints on buildings, pedestrian slabs, concrete walls or roof tiles, they can significantly increase the decomposition of pollutants such as nitrogen oxides, aromatics and aldehydes in the air.


It is also widely used in the production of sunscreens, non-toxic and harmless to the human body.


Ultrafine titanium dioxide has excellent UV shielding and transparency.


It is widely used in cosmetics, wood protection, food packaging plastics, durable household films, rayon and natural fibers, and clear coatings.


The special optical effect in metallic flash paints has made it a priority and application in premium car paints.
