【摘要】 本文在实验的基础上研究了国产ＳＸ８２１硅藻土助滤剂的湿性能。研究结果表明ＳＸ８２１硅藻土助滤剂具有一定的可压缩性；过滤过程的阻力具有较明显的时效性。本文分析了硅藻土粉体的结构特性和堆积特性，对硅藻土助滤剂这种湿性能进行了论证与探讨。更多还原

【Abstract】 In this paper,experimental results of the moist performance of the SX-82 1 diatomaceous-earth filtration is reported. It shows that the diatomaceous-earth-filtration-aid is somewhat compressible and the resistance in the process of filtering is time -dependent.The structur-al characteristica and the heap perfomance of the diatomaceous-earth power are detailed.更多还原
