Facing the Rising Price of Titanium Dioxide, Where Should We Go?
Due to the Environmental Protection Actions taken by Chinese government, the price of titanium dioxide will increase constantly in the future.
The world's three largest titanium dioxide tycoon announced the rising price together
I believed that the two news above has been spread in the industry.
So how do we go out the awkward situation?
Recently, a good news was spread that titanium dioxide can be replaced by silica powderaccording to some industry.
It is shown that the maximum can be replaced by 20% !
What is silica powder ?
Silica powder is made from natural quartz (SiO2) or fused silica (an amorphous SiO2 which is melted by high temperature and cooled ), processed by crushing, ball milling (or vibration, airflow grinding), flotation, pickling and purification, high purity water treatment and so on.
Why can silica powder replace titanium dioxide?
Silica powder is non-toxic, tasteless and pollution-free. It has the characteristics of low impurity, high fineness, high hardness, strong coloring power, high resistivity, acid and alkali resistance and so on.
It has the advantages of good dispersibility, suspension, thixotropy.
It also can improve the storage stability and antidripping of paint and coating under construction. At the same time, it greatly reduces the amount of Modified Bentonites. That means the powder not only improves the performance of paint and coatings, but also reduces the comprehensive cost. For example, adding silica powder in high temperature coating (ceramic coating) can not only play a role of filling and compatibilization, but also improve the hardness of paint film, enhance paint resistance, scratch resistance and corrosion resistance, and also has the performance of auxiliary extinction.
Compared with the properties of coating grade titanium dioxide and coating grade silica powder, there are many similar characteristics. Therefore, it is feasible to replace titanium dioxide with silica powder.
After all, comparing to the increased price of titanium dioxide, silica powder cost is much more lower.
