Influences of Coating Methods on Properties of Titanium Dioxide

摘要: 分别以锌盐系钛白砂磨后浆料和铝盐系钛白砂磨后浆料为原料,考察了偏铝酸钠-硫酸并流包膜工艺、偏铝酸钠-硫酸铝并流工艺和偏铝酸钠-硫酸铝串流包覆工艺对钛白颜料性能的影响。试验结果表明:三种氧化铝包膜工艺对产品的Jasn (亮度)、消色力、白度等颜料性能影响不大。相比偏铝酸钠-硫酸并流包膜工艺,采用偏铝酸钠-硫酸铝串流工艺产生的副产物少,相同洗涤条件下可得到电阻率高、吸油量较低的钛白产品,在工业生产应用中具有明显效果。

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.
