Abstract

Abstract

Based on the production data of a certain titanium dioxide factory, the influence of the sedimentation height of metatitanic acid on its particle size distribution and titanium dioxide pigment properties was statistically analyzed. The results show that with the increase of sedimentation height, the D₅₀ of metatitanate shows an increasing trend, while the Tcs and Scx of titanium dioxide pigment show a decreasing trend, and the average particle size shows an increasing trend. Controlling the sedimentation height of titanium dioxide below 130 mm can obtain titanium dioxide with better pigment properties. The experimental results show that the TiO₂ concentration, F value, seed addition, and first boiling holding time of titanium liquid all have a significant impact on the sedimentation height and D₅₀ of metatitanic acid. As the concentration of TiO₂ increases, the sedimentation height and D₅₀ of metatitanic acid show a decreasing trend. As the F value increases, the sedimentation height of metatitanic acid and D₅₀ show an increasing trend. With the increase of seed addition, the sedimentation height of metatitanic acid shows a decreasing trend. With the extension of the first boiling insulation time, the sedimentation height of metatitanic acid shows a trend of first increasing and then decreasing.
