摘要
确定了氧化温度为240～280℃时三种原料渣油氧化制备10号沥青的工艺参数,试验表明,渣油软化点低时可以通过增加通风速度、缩短氧化时间生产出合格的10号建筑沥青。
The processing parameters of the oxidated asphalt produced from three kind of vacuum residue under the oxidation temperature of 240-280℃ were ascertained. If the softening point of these residuums was low. The construction asphalt number 10 up-to-standard can be produced by increasing ventilation velocity and shortening the oxidation time.
