摘要
在惰性气氛中，利用差热分析仪研究了不同添加剂改质煤沥青筑路油中沥青质的热失重情况。试验表明，沥青质失重与温度的关系符合一级反应动力学。由活化能可推测出沥青质是由不同分子量组成的复杂混合物。
The thermal weight loss of asphaltine in the pitch road building oil modified with different additives is studied with derivative thermo - gravimetric analyzer in inert atmo- sphere. Test shows that the relationship between the weight loss of asphaltine and temperature conforms with one stage reaction kinetics. It can be inferred from activation energy that asphal- tine is a complicated mixture formed with different molecular weights.
