加氢基础油对极压抗磨剂及金属钝化剂感受性的研究

STUDY ON RECEPTIVITY OF HYDRO-TREATED BASE OILS TO EP ADDITIVES AND METAL DEACTIVATORS

加氢基础油具有许多溶剂基础油不可比拟的优点,但由于加氢基础油的组成与溶剂精制基础油的组成差别较大,通过加氢基础油对极压抗磨剂、金属钝化剂等添加剂感受性的研究,结果表明,加氢基础油对极压抗磨剂的感受性优于溶剂基础油,对金属钝化剂的感受性逊于溶剂基础油。

Hydro-treated base oils have many unmatched merits over solvent-treated base oils. Due to the great difference in composition between these two kinds of base oils, the receptivity of hydro-treated base oils to extreme pressure additives and metal deactivators was investigated. The results showed that hydro-treated base oils have better receptivity to extreme pressure additives than solvent-treated base oils, but they are inferior to solvent-treated base oils in the receptivity to the metal deactivators.
