Important index granularity of titanium dioxide powder

- Jun 26, 2017 -

The particle size distribution of titanium dioxide is a comprehensive index, which seriously affects the performance of titanium dioxide pigments and the application performance of the products, so the discussion of the covering force and dispersion can be analyzed directly from the particle size distribution.

The factors affecting the particle size distribution of titanium dioxide powder are more complex, first, the size of the original particle size, the original particle diameter is controlled and regulated by the hydrolysis process conditions, and then the calcination temperature, the acid in the calcination process, particles undergo a crystalline transformation period and growth period, control the appropriate temperature, so that the growth of particles in a certain range; Finally, the product is crushed, usually to Raymond Mill's transformation and analyzer speed adjustment, control of crushing quality, but also can use other crushing equipment, such as: Universal grinding , Airflow Pulverizer and hammer mill.
