Study and application of soft pitch-oxy/fuel burner system for melting;
软沥青—氧燃助熔系统的研究与应用
Refined soft pitch was obtained from the distillation of high temperature coal tar at 280 oC,extraction with solvent and then settlement,which was carbonized at 500 oC for 4h to afford the distillate.
以高温煤焦油为原料,蒸馏至280℃得软沥青,再经溶剂萃取沉降分离得煤焦油精制软沥青,在恒温500℃炭化4 h得馏出物。
In order to study the interaction among SBS,asphalt and maltenes,the microstructure of polymer phase in asphalt is gotten by fluorescence optical microscopy.
为了研究苯乙烯 -丁二烯嵌段共聚物 (SBS)与沥青、软沥青质的相互作用及其过程 ,采用荧光显微照相技术获得聚合物相在沥青中的显微结构 ,发现SBS在沥青中的溶胀、分散是一个动态平衡的过程 ,沥青质及聚合物都需要足够的软沥青质来维持其在沥青中的稳定 ;SBS改性沥青具有热溶胀冷析出的特点 ,SBS相的形态结构受降温速率的影响 ,改性沥青中的软沥青质在常温存贮过程中会从SBS相中部分析出 ,造成聚合物相的面积百分率减少 ,软化点下降 ,存贮稳定性下降 。
