摘　　要：借助燃烧法、显微镜法、溶解法、熔点法以及红外光谱法等5种定性鉴别方法,分别研究了常见7种高温过滤材料的特性。研究认为,根据常见聚酯纤维、聚酰亚胺纤维、芳纶1313、聚噁二唑纤维、聚苯硫醚纤维、玻璃纤维、聚四氟乙烯纤维的燃烧现象、显微镜形态、溶解性能、熔点以及红外吸收光谱特性,可以有效地对高温过滤材料进行定性鉴别。The characteristics of seven kinds of high temperature filtration materials were studied by means of five qualitative identification methods,such as combustion method,microscope method,dissolution method,melting point method and infrared spectroscopy.It is considered that the high temperature filtration materials can be qualitatively identified effectively according to combustion phenomenon,microscope morphology,solubility,melting point and infrared absorption spectrum characteristics of common polyester fiber,polyimide fiber,aramid 1313,aromatic polyoxadiazoles fibers,polyphenylene sulfide fiber,glass fiber and polytetrafluoroethylene fiber.
