(续1980年第二期)五、阳离子沥青乳液的制备1.沥青材料:前面己述阳离子沥青乳液不太受沥青的组份和针入度的影响。到目前在国内已试用胜利油田的沥青和渣油、兰炼的沥青和渣油、大庆油田的沥青等不同的油料制备了阳离子沥青乳液,配制效果良好。但这只是开端。我国沥青质量波动很大,乳化剂品种又少,今后在这方面还要做大量的工作。 (Continued 1980 second) Fifth, the preparation of cationic bitumen emulsion 1. Bitumen material: Cationic asphalt emulsion has been described earlier less affected by the composition and penetration of bitumen. Up till now, cationic asphalt emulsion has been prepared from asphalt and residue oil from Shengli Oilfield in China, bitumen and residue from Lan Lian, bitumen of Daqing Oilfield, etc., and the preparation effect is good. But this is just the beginning. Asphalt quality in our country fluctuates greatly, with fewer varieties of emulsifiers. In the future, a great deal of work needs to be done in this regard.
