Titanium dioxide has the function of sunscreen. Isn't it going to be very popular in the beauty industry and will be strongly pursued by beauty lovers?

After all, women must be the biggest audience.

Why is it that in daily life, there is no news that someone has hoarded tons of titanium dioxide and left it at home for standby?

In fact, the "sun protection" function of titanium dioxide is not equivalent to the "sun protection" mentioned in our daily life but refers to the "sun protection" measures taken to protect the "white" function of titanium dioxide. If titanium dioxide is exposed to ultraviolet light for a long time, it will catalyze the free radical oxidation and decomposition of the organic matrix on its surface, resulting in yellowing, loss of light, chalking and other phenomena of the organic matrix, which will seriously affect the service performance of the organic matrix in titanium dioxide and shorten its service life. It can be popularly understood as the skin "oxidation" said by beauty bloggers. Since we know that we should help our skin resist the invasion of ultraviolet rays, titanium dioxide manufacturers also know that we should do a good job in "sunscreen" for titanium dioxide.

In order to reduce the catalytic effect of titanium dioxide surface and improve the dispersion of titanium dioxide in the organic matrix, the manufacturer will generally cover the surface of titanium dioxide, to broaden the application channel of titanium dioxide in the market.

What kind of coating treatment does the manufacturer usually do for titanium dioxide? The most common are the followings

- Alumina coating

- Silica coating

- Zirconia coating

What are the differences between them, and what impact do they have on titanium dioxide?
