摘　　要：为了研究不同检测方法对沥青基防水卷材用基层处理剂灰分含量测试结果的影响,从处理方法、灼烧时间、坩埚容量3个方面进行了对比分析。结果表明,样品在灼烧前的处理方法对灰分含量的测试结果几乎没有影响,但无处理的样品可以缩短测试时间,有效提高工作效率;相同的灼烧时间下,随着坩埚容量的增大,灰分含量逐渐减少,且当坩埚容量超过100 mL时,相同灼烧时间下的样品灰分基本保持不变;对于同一大小的坩埚,随着灼烧时间的延长,灰分含量逐渐降低,样品灰化越充分。In order to study the influence of different testing methods on the ash content of primer of substrate used for asphalt waterproofing sheet,the influencing factors on ash content are compared and discussed,including treatment method,burning time and crucible capacity.The results show that treatment methods of samples before burning have no influence on ash content,but the sample without treatment can shorten testing time and improve work efficiency effectively;under the same burning time,the ash content decreases with the increasing of crucible capacity,and when the crucible capacity is more than 100 mL,the ash content of samples remains unchanged at the same burning time;for the same crucible,the longer the burning time,the lower the ash content,and the more fully ashing of the sample.
