Study on the Salt Treatment Technology of the Titanium White by Aluminum Sulfate
-
摘要: 研究了硫酸铝作为钛白粉的盐处理剂对钛白初品的作用规律,主要包括硫酸铝对钛白初品金红石晶型转化率、消色力、白度、粒子形貌等方面的影响。试验表明:硫酸铝是金红石晶型转化抑制剂,铝盐在钛白粉中含量在0.08%~0.28%范围内对钛白初品消色力几乎无影响。当钛白初品中铝盐含量在0.05%~0.10%范围内,钛白初品白度值随着含铝量的增加而增长,当铝盐含量在0.10%~0.50%范围内,钛白初品白度值随着铝盐含量增加反而不断降低。研究显示硫酸铝的加入有利于钛白初品粒子按四方晶系生长。Abstract: The effect of aluminum sulfate as salt treatment agent on the properties of titanium dioxide initial products,mainly including the rutile conversion rate,achromatic energy,whiteness and particle morphology,was studied. The results show that aluminum sulfate is inhibitor of rutile transformation and has almost no effect on achromatic energy of titanium dioxide initial products with content of 0.08%~0.28%. The whiteness value of titanium dioxide initial products increases with increasing aluminum salt content in the range of 0.05%~0.10%,while it continuously decreases with increasing aluminum salt content in the range of 0.10%~0.50%. It is also found that addition of aluminum sulfate favors the growth of tetragonal system particles for titanium dioxide.
