优质页岩陶粒滤料的制备与基本性能研究

Study on preparation and performances of shale ceramsite filter

以天然页岩为原料,分别采用破碎法和成球法制成滤料生料,经焙烧,膨胀,制备了陶粒滤料。对这2种方法制备的陶粒滤料的孔隙率、孔径和酸碱可溶率等指标进行了分析比较。结果表明,2种方法均可制备出性能优异的陶粒滤料。陶粒滤料的制备方法对其性能影响不大,而焙烧程序对陶粒滤料的性能有较大影响。实际生产时,可根据页岩特性、生产成本等确定陶粒滤料的制备方法。

The natural shale was made into good performance ceramsite filter by ball making,and breaking processes. The porosity, pore diameter and solubility of ceramsite filter made by these two methods were analyzed and compared. The results showed that the good performance ceramsite filter can be made by the two processing methods, the processing method had a less effect on the performance, but the sinter schedule had an great effect on it. The processing method was selected by the characteristics of natural shale and production cost in the manufacture.
