摘要
通过对比试验确定沥青低含量喹啉不溶物试验方法,确定了过滤用古氏坩埚的孔径范围及相应的型号,讨论了助滤剂对测试结果的影响及试验方法的测定原理,规定了测试条件及精密度。
On the basis of the comparative experiments, the method for measuring the content of QI in coal tar pitch is established. The suitable type and the aperture size range of the Gushi crucible for filtering are tested and discussed. The influence of adding filter aid on the test results is evaluated. The principles involved in the test method as well as the test parameters and the precision are also presented.
