以六偏磷酸钠为分散剂，采用液相沉积法在金红石型钛白粉表面进行了 ZrO 2的包膜，研究了六偏磷酸钠添加量对包膜的影响.通过 zeta 电位分析仪、透射电子显微镜等，对分散后的浆液和包膜后的样品结构和性能进行了表征.结果表明，当六偏磷酸钠添加量为钛白粉质量的1．0％时，包膜质量最好.
Taking SHMP as the dispersing agent,we've used the method of liquid deposition to coat the ZrO 2 on the surface of the rutile titanium dioxide and studied the influence of adding quantity of SHMP on envelope.The structure and performance of the dispersion of the slurry and samples being coated have also been characterized by zeta-potential-analyzer,TEM etc.The results show that the best coating could be got when the quantity of SHMP being added was 1.0% of that of titanium dioxide.
