摘要
首先简述石墨在水中的分散机理,然后综述了评价水系浆料中鳞片石墨分散效果的常用方法(包括沉降法、光学法、流变法、Zeta电位测量法、测量浇注料流动值法以及显微镜法等)的原理及优缺点。由于这些方法大多仅适用于微细鳞片石墨,因此,亟需确定大鳞片石墨的分散效果评价方法。
The dispersion mechanism of graphite in water was reviewed firstly, and then the principles, advantages and disadvantages of conventional methods for evaluating dispersion effect of flake graphite in water slurry system,including sedimentation method, optical method, rheological method, Zeta potential measurement method,flow value measurement method of castables and microscope method,were summarized. A new method for evaluating dispersion effect of large flake graphite was urgently demanded, as most methods mentioned above were applied only to ultrafine flake graphite.
