摘要 研究了添加对甲苯磺酸对沥青不熔化处理的影响 ,试验发现对甲苯磺酸的加入促进了沥青的分解以及沥青与氧的结合 ,加速了沥青不熔化的过程。不熔化处理后的沥青在炭化时表现出明显不同的特点。 The influence of the pitch additive on the infusibility and carbonization is investigated in this paper.The results show that the pitch crack and the reaction between pitch and oxygen are enhanced.It is also found that the velocity of pitch stabilization process is increased.The stabilized pitch exhibites different carbonization features.
