为了研究聚合氯化铝对煤泥压滤的作用机理,采用激光粒度分析仪和X射线衍射仪(XRD)对煤泥水粒度分布和矿物组成成分进行测试分析煤泥性质,添加不同用量的聚合氯化铝来测煤泥表面的Zeta电位,进行加压过滤形成滤饼观察其内部结构。
In order to study the action mechanism of polyaluminum chloride on the pressure filtration of coal slime, the particle size distribution and mineral composition of slime water were analyzed by laser particle size analyzer and X-ray diffraction (XRD) to analyze the properties of slime and the addition of different dosage of PAC Aluminum to measure the surface of the slurry Zeta potential, pressure filtration to form a filter cake to observe its internal structure.
