研究了3种分散剂对钛白粉的分散性能,结果表明硅酸钠、六偏磷酸钠和 DA1705都有分散效果,且DA1705的分散效果最好。并从表面电位方面分析了分散机理,3种分撒及都是通过水解成离子状态,吸附在颗粒表面,使颗粒表面带电,增加了彼此的排斥力,阻止了颗粒之间的团聚。

The paper describes the effect of three kinds of dispersants dispersion on titanium oxide.The results shows that the three dispersants (sodium silicate,sodium hexametaphosphate and DA1705)all have dispersion effect,among which DA1705 is best.The paper analyzes dispersion mechanism from surface potential.Because three dispersants are hydrolyzed into ionic condition and adsorb to particle surface, it makes particle surface charged and increases repulsive force then prevent agglomeration between each other.
