摘    要:对胶粉在沥青中脱硫降解后的溶解度测试法进行比较研究。认为离心法与抽提法两种皆可用,但离心法对抽提法有正误差。提高温度会使沥青与橡胶之间的传质增加,溶解量增大。增加胶粉加入量会提高沥青的粘度,使体系内部之间的传质下降,以百分比计的橡胶的表观溶解度下降,但橡胶的绝对溶解量仍会增加。

关 键 词:废胶粉  溶解度  传质  加入量  橡胶  抽提法  沥青  增加  下降  内部

Abstract:The methods for determination of solubility of crumb rubber after desulphurization and degradation in bitumen are compared. The result shows both centrifugal and extraction methods are working and the former has positive error towards the latter. When temperature up the mass transfer between bitumen and rubber increases and so does rubber dissolved. Adding more crumb rubber will increase viscosity of bitumen and decrease mass transfer in the system and apparent solubility of rubber calculated in percentage but rubber dissolved is still increased.
Keywords:crumb rubber  bitumen  modified bitumen  solubility
