| 中文摘要: |
| 探索炭黑粒径分布与炭黑品种之间的关系，建立通过炭黑粒径分布鉴别炭黑品种的方法。通过热裂解法回收硫化胶中的炭黑，将回收的炭黑加入分散剂制成悬浊液，利用纳米激光粒度分布仪进行粒径分布测试。结果表明，不同品种炭黑粒径分布的峰值和标准偏差不同，同种炭黑粒径分布的峰值和标准偏差在一个较小的范围内波动，这是硫化胶中未知炭黑品种鉴别的依据。本方法适用于单一炭黑品种硫化胶分析，不适用于并用炭黑及炭黑N774硫化胶分析。 |
| 英文摘要: |
| The relationship between particle size distribution and carbon black type was established and the test method to determine the carbon black type in vulcanized compound was obtained by particle size distribution analysis.The carbon black in the vulcanized compound was recovered by pyrolysis and its particle size distribution was measured by laser diffraction nano-particle size analyzer.The results showed that peak value and standard deviation of different type of carbon black were different and the peak value and standard deviation fluctuated within a small range for the same type of carbon black.Thus the unknown carbon black could be identified by measuring its particle size distribution.This identification method was suitable for analysis of carbon black in the vulcanized compound filled with only one type of carbon black and it could not be applied to blended carbon black and carbon black N774. |
