山东胜利炼油厂以往采用轻度氧化法生产100号甲道路石油沥青,在全国不少城市的使用过程中,感到当前它在国产石油沥青中质量是较好的,但它的低温性能仍不够理想,北方修筑的路面,在严冬季节仍有裂纹出现。该厂为了进一步提高道路石油沥青的质量,更好地满足道路施工要求,1980年初改进了生产过程,采用在减压釜内提高真空度的直馏深拔新工艺,得到100号甲直馏道路石油沥青。它与过去生产的100号甲氧化
Shandong Shengli Refinery used mild oxidation method to produce No.100 asphalt road asphalt in the past, and in the process of using it in many cities throughout the country, it felt that it is better in domestic petroleum asphalt quality, but its low temperature performance is still not ideal Roads built in the north have cracks in the winter season. The plant in order to further improve the quality of road asphalt, to better meet the requirements of road construction, improved production process early 1980, the use of vacuum within the autoclave to increase the degree of vacuum straight draw deep drawing process, get 100 A straight road asphalt. It was produced in the past with No. 100 Methoxide
