摘　　要：以聚乙烯(PE)粒料、管材、管件(PE100、PE80)和炭黑母料[PE、聚丙烯(PP)]为研究对象,利用传统马弗炉法、管式电炉法、热重分析法及微波马弗炉法测定不同样品中的炭黑含量,并对其测定结果进行分析,探究了4种方法对PE中炭黑含量的测量准确性。结果表明,采用热重分析法测定PE塑料中的炭黑含量时,检测结果具有较高的准确率和良好的重复性。Taking polyethylene(PE)pellets,pipes,fittings,and carbon black masterbatch(PE,polypropylene)as research objects,the carbon black contents in different samples were determined by using traditional muffle furnace,tubular electric furnace,thermogravimetric,and microwave muffle furnace methods.The measurement results were analyzed,and the accuracy of these four methods for measuring carbon black content in polyethylene was investigated.The results indicated that thermogravimetric method had a high accuracy and good repeatability.
