| 中文摘要: |
| 介绍不溶性硫黄（IS）的热稳定性和分散性及其评价方法，总结不同评价方法的差异。IS热稳定性分析以恒温油浴过滤法为主，结果受测试用矿物油、设备以及操作因素等的影响较大，开发在更大程度上利用仪器测试的方法是IS热稳定性分析的发展方向。IS分散性测定目前尚没有统一的标准，研究制定科学有效的分散性测试标准是IS生产企业和轮胎企业共同的需要和任务。 |
| 英文摘要: |
| This paper discussed the thermal stability and dispersion of insoluble sulfur (IS)，and summarized the difference between testing and evaluation methods.The main evaluation method of IS thermal stability was filtration using the constant temperature oil bath，but the test results were heavily impacted by the mineral oil，equipment variables and operation factors.Therefore，there was need to develop a new method which had smaller variation.For the dispersion of IS，currently there was no standard test method，and establishment of a standard test method would need collective efforts from IS manufacturers and tire companies. |
