Effects of Initial Feed Speed of 1 Min on Rutile White Pigment Production via Short Sulfate Process

Abstract:

Hydrolysis is one of the crucial steps in the product of titanium white pigment via sulfate process, and determines quality of the final products. Feed Speed have important effect to the quality and the numbers of seeds of early hydrolyzing. Using low concentration TiOSO₄ as raw materials, fine rutile white titanium pigment was prepared by optimizing the key parameters of the hydrolysis process via the achromatic force and the level of whiteness of the samples. The samples were characterized by SEM, particle size distribution and pigment properties test. Resultes have shown that the feeding speed of 1 min is 1.1times to the speed after 1 min. In this conditions, the obtained titanium white pigment showed better pigment performance.
