| 摘 要： | 对2种高岭土(MMO1和Premium)的流变性进行了研究,探讨了固含量、分散剂用量以及pH值对颜料分散液高剪切黏度的影响。结果表明,MMO1的最佳分散剂用量为0.15%,Premium的最佳分散剂用量为0.10%;要获得较好的高剪切特性,MMO1分散液pH值应调至8.0以上,但不应太高,Premium分散液pH值也应调至8.6左右较好。MMO1的固含量控制在68%左右较合适。而Premium固含量对高剪切黏度的影响较MMO1的明显,其分散液固含量一般控制在69%~70%。

| Abstract: | The rheological properties of two types of clay were studied in the lab,the effects of solid content, dosage of dispersant and pH on low shear rate viscosity and high shear rate viscosity of the slurries were investigated. The results showed that the optimum addition of dispersant for MMO1 is 0.15%(wt%), while for Premium is 0.08% . In order to get better high shear rate property, the pH of the slurry containing MMO1 should maintain over 8.0, and the pH of Premium slurry should be about 8.6. The solid content of the slurry containing MMO1 is better to control at 68%, and for the slurry containing Premium is 69%~70% . |
