加压碳化提高了沥青的产碳量,压力影响沥青中间相的形成过程,改变了碳化机理和碳的微观结构,同时,也改变了性能。高压沥青浸渍-碳化过程已有许多研究,并应用于碳-碳复合材料制造工艺。 本文研究了鞍山中硬煤沥青在600℃温度
Pressurized carbonation increases the carbon production of the bitumen, the pressure affects the formation of the bitumen mesophase, changes the carbonization mechanism and the microstructure of carbon, and at the same time, changes the properties. Many studies have been conducted on the impregnation-carbonization of high-pressure bitumen and applied to the carbon-carbon composite manufacturing process. This paper studies the Anshan medium hard coal pitch at 600 ℃ temperature
