| 摘 要： | 采用热重／差热分析、核磁共振、热台显微镜在位观察等方法，对太钢改质沥青和北京焦化厂中温煤沥青的软化点、元素组成、结构、组成、粘度进行了分析，以评价其作为浸渍沥青的性能。结果表明：太钢改质沥青比北京焦化厂中温煤沥青的吡啶不溶物含量高，芳香度低，高温流动性略好，产碳率也高。

| Abstract: | s: The analysis of softening point,elements,structure,consists,rheology of two kinds of pitch was investigated,by thermogravimetric/differential thermogravimetric(TG/DTG)and differential thermal analysis(DTA),nuclear magnetic resonance(NMR)and the reaction properties observed at hot stage optical microscope.The results show that the modified coal tar pitch from Taiyuan Iron and Steel Plant has more PI parts,higher carbon yield,lower viscosity and aromatic index than the middle softening point pitch from Beijing coke-oven plant. |
