Abstract:

Aiming at the current lack of systematic and perfect analysis and testing standards for high-temperature resistant fibers at home and abroad, the problem of unrealistic mixing ratio of high-temperature resistant fibers in the filter media market and the uneven quality of products, a summary was made based on the research results and progress of the analysis and testing of existing high-temperature composite filter media fibers. This paper introduced the high temperature filter media industry commonly used organic fibers, inorganic fibers and their physical and chemical characteristics, focusing on an overview of conventional detection methods such as chemical dissolution method, combustion method, modern testing techniques such as infrared method, thermogravimetric method, differential thermal method, polarized light method, and the use of multi-instrument combined use of technology in the composite filter media fibers quantitative and qualitative analysis of the current status of the test. Combined with the pros and cons of the measured method of high-temperature resistant fibers, the future development trend of analysis and testing was proposed. It was believed that since the conventional combustion method was subject to subjective influence and dissolution method polluted the environment, the future analysis and testing of high temperature composite filter media fibers should take into account the modern testing technology to explore a variety of methods and combination of different technologies, and should be accelerated in the future to improve the quantitative analysis and testing standards of high temperature fibers.

Key words: high-temperature resistant fibers, composite filter material, qualitative analysis, quantitative analysis, fiber detection

摘要：

针对目前国内外缺乏系统完善的耐高温纤维分析检测标准、滤料市场中耐高温纤维混用比例不实、产品质量良莠不齐的问题，基于现有高温复合滤料纤维分析检测的研究成果及进展进行总结。介绍了高温滤料行业中常用的有机纤维、无机纤维及其物化特点，重点综述了常规检测法如化学溶解法、燃烧法，现代测试技术如红外法、热重法、差热法、偏振光法以及多仪器联动组合使用技术在复合滤料纤维定量定性分析检测的测试现状，并结合实测方法应用的优劣势，展望了耐高温纤维未来分析检测的发展趋势。由于常规燃烧法受主观影响、溶解法污染环境，未来高温复合滤料纤维的分析检测应考虑现代测试技术并探索多种方法、不同技术的组合使用，今后应加快完善耐高温纤维的定量分析检测标准。
