超细加工提高龙岩高岭土可塑性研究

Research for Increase of Longyan Kaolin Plasticity by Ultrafine Processing

以45μm高岭土为原料,通过超细加工提高其-2μm含量,得到陶瓷用60级、70级超级高岭土产品,其可塑性指数分别为0.781、0.878,较45μm高岭土可塑性指数0.658分别提高18.7%、33.4%。

Taking Longyan 45 μmkaolin as raw materials, increase the -2 μm content by ultrafine processing. The kaolin products with -2 μmcontent of60%-70% and 70%--80% can be obtained, the plasticity of which increase by 18.7% and 33.4%, respectively compared with 0.658 of 45μmkaolin.
