摘　　要：采用GB 13021《聚乙烯管材和管体炭黑含量测定(热失重法)》和热重分析仪法两种方法测定了聚乙烯中炭黑含量。对两种方法的测定结果进行了比较,结果表明,两种方法均有良好的重复性和准确度,测定结果基本一致,采用不同方法得到的测定结果间可以相互参考。The carbon black content in PE was determined by two methods of GB 13021 and thermogravimetry. The determination results of both methods were compared. The result showed that two methods both had good repeatability and accuracy. The test results derived from different methods were consistent and could be compared with each other.
