均匀设计在优化钛白粉无机包膜工艺中的应用

Application of the uniform design in the optimizing technology of the titanium dioxide inorganic coated

采用溶胶-凝胶法,研究了金红石型钛白粉锆硅铝三元无机包膜的新工艺。通过均匀实验设计,系统研究了各因素对金红石型钛白粉三元无机包膜性能的影响,采用Nano-ZS、傅里叶红外光谱仪(FT-IR)、扫描电镜(SEM)、透射电镜(TEM)、能谱(EDS)等测试手段,考察金红石型钛白粉三元无机包膜的包膜效果。金红石型钛白粉三元无机包膜工艺的优化配方为:分散剂为0.20%,Zr含量为0.6%,Si含量为3.0%,Al含量为1.6%,转速为340r/min。

This paper researched the new technology of the rutile titanium dioxide ternary inorganic coated by sol-gel method. The regression equation and the optimum conditions are founded by uniform design and the systemetical research of various factors on the properties of the rutile titanium dioxide ternary inorganic coated. Effect of the rutile titanium dioxide ternary inorganic coated were characterized by nano-ZS, Fourier infrared spectroscopic analysis （FT-IR）, scanning electron microscopy （SEM）, transmission electron microscopy（TEM）. The optimized formula of preparing the rutile titanium dioxide ternary inorganic coated was that the dispersant of 0.20 %, the ZrO2 content of 0.6%, the SiO2 content of 3.0%, the A12Oa content of 1.6%, the rotate speed of 340r/min.
