SV261与RHY615性能比较及SV261在不同基础油配方中的应用

The Performance Comparison of VIIs SV261 and RHY615 and the Application of SV261 in Different Base Oil Formulations

通过两种不同种类的黏度指数改进剂SV261与RHY615的性能比较,得出SV261具有更强的增稠能力、更优的低温性能及高温剪切安定性。采用SV261生产油品可灵活选用基础油,可增加重组分基础油比例降低挥发度,可提高产品的燃油经济性。合理的使用SV261可有效地优化配方,降低成本。

By comparing the performances of Vlls SV261and RHY615, a conclusion was obtained that SV261 has stronger thickening ability, better low temperature performance and high temperature shear stability. When SV261 is employed in products production, it can bring the flexible selection of base oil, the increase of the proportion of heavy constituent base oil in order to decrease the volatility and the increase of the fuel economy of products. Reasonable usage of SV261 can ef- fectively optimize the formulation and lower the cost.
