Abstract

Abstract

The influences of coating methods of NaAlO₂-H₂SO₄ parallel flow,NaAlO₂-Al₂(SO₄)₃ parallel flow and NaAlO₂-Al₂(SO₄)₃ series flow on the pigment properties of TiO₂ were investigated with sand milling slurries of TiO₂ respectively treated by zinc and aluminum salt as raw material.The results indicate that the properties of TiO₂ including brightness,achromic ability and whiteness are not much affected by the coating methods mentioned above,and products with less byproducts,higher resistivity and lower oil absorption under the same washing conditions can be obtained by NaAlO₂-Al₂(SO₄)₃ series flow process in comparison to the NaAlO₂-H₂SO₄ parallel flow process.Obvious effects are achieved by the industrial application of NaAlO₂-Al₂(SO₄)₃ series flow process.
