中文摘要:
      为解决纳米 ATO 在水中的分散问题,通过沉降实验和测定 Zeta 电位,考查了 pH 值、分散剂及其用量、研磨时间等对纳米 ATO 浆料分散稳定性的影响,得出了最佳分散条件:采用高分子型分散剂 Tech-6300 ,pH值 8 ~ 9 ,研磨时间为 12 h。 对最佳分散条件制备的 ATO 水性浆料进行粒径检测和透射电镜观察,结果表明,ATO水性浆料的粒径在 100 nm 以内,达到了纳米级别,分散稳定性较好。
英文摘要:
      To solve the problem of Nano ATO dispersion in water, measured by sedimentation experiments and Zeta potential, the influence of parameters such as pH values, different type and content of dispersants, and different milling time on stability of ATO dispersion was discussed, and the optimum dispersion conditions: using polymeric dispersant Tech-6300 , at pH = 8 ~ 9 , and the milling time of 12 hours. By laser particle size analysis and transmission electron microscopy ( TEM) experiment , the results indicated that, the ATO water-based slurry prepare by optimum dispersion conditions had good dispersion stability, and its particle size was less than 100 nm, reaching the nanometer level .
