摘要
旨在探索一种用煤灰作助滤剂的方法,从理论上分析了助滤原理,并用大量试验来证实煤灰作助滤剂 的可行性。结果表明:用煤灰作助滤剂,测定煤沥青的喹啉不溶分的过程中,可显著提高过滤速度,所得数据 准确度高。
This paper is expeored to study a way that make use of fly ash filter-aid. The mechanism of filter-aid is analyzed on theory,and a lot of tests are done to verify the feasibility of fly ash filter-aid. The result shows:during determination of coal tar pitch quinoline insoluble,fly ash acting as filter-aid can significantly improve the filter speed and the obtained datas have high precision and accuracy.
