1) n-alkylbenzenes
正构烷基苯
2) long-chain alkylbenzene
苯基长链正构烷烃
3) hydrocarbon in different state
正构烷基酮
4) p-alkyl benzoic acid
对-正烷基苯甲酸
5) n-alkane stock oil
正构烷烃基础油
1.
The results show that load-carrying capacity of n-alkane stock oil is higher than that of hydrotreating stock oil,the load-carrying capacity of hydrotreating s.
实验结果表明,在同类基础油中,正构烷烃基础油的油膜承载能力比加氢基础油的高;在加氢基础油中,随着链烷烃减少,环烷烃增加,基础油的油膜强度降低;但加入润滑添加剂后,含有环烷烃的加氢轧制油的摩擦性能比正构烷烃轧制油的摩擦性能更好,这表明与正构烷烃基础油相比,加氢基础油与润滑添加剂有更好的协同效应。
6) n-alkylphenol
正构长链烷基酚
