摘要
采用中温沥青、改质沥青、浸渍沥青3种沥青试样,经过两种不同温度曲线炭化后,利用偏光显微镜、扫描电镜分析煤沥青炭化后的显微结构特征。结果表明,3种沥青炭化后的显微结构有所区别,不同的温度曲线对沥青炭化后的显微结构有一定影响。
Three pitch samples including medium pitch, modified pitch and impregnated pitch were carbonized with different temperature-rising programmes. The microstructure of carbonized pitches were characterized by polarized light microscope and scanning electron microscope. The results showed that the microstractures of three pitches are different, and the carbonization temperature has effects on the microstructure of carbonized pitches to some extent.
