The results indicated that ovcrbased calcium petroleum sulfonates containing calcite formed thicker calcium carbonate film on rubbing surface than that containing amorphous calcium carbonate, which was a main reason that the former had better extreme pressure performance than latter.
本文采用X-射线光电子能谱(XPS)仪,对FALEX试验后的摩擦表面进行分析测试,结果表明, 方解石型高碱石油磺酸钙能在摩擦表面形成较厚的含碳酸钙保护膜,无定形型高碱石油磺酸钙在摩擦表面形成较薄的含碳酸钙保护膜,这是二者极压性能差别较大的主要原因。
The paper describes the process of experiment and damage and analyzes the experimental result,with which the compression resistance of slender high co.
描述试验及破坏过程并对试验结果进行分析,得出黄河淤泥多孔砖中长柱的抗压性能,结果表明其与实心黏土砖同类构件受力破坏规律相同,在开裂荷载、承载力等方面优于实心黏土砖。
Emulsion liquid has higher P b value than emulsion oil,and emulsion concentration has little influence on extreme pressure property in the range of concentration of 20g/L～100g/L.
对含有不同极压剂、不同极压剂浓度和不同类型（如阳离子、非离子等）的轧制乳化液进行了极压性能的研究；探讨了含硫乳化液在极压状态单分子反应层生成的速率，乳化液比乳化油有较高的Ｐｂ极压值；在２０ｇ／Ｌ～１００ｇ／Ｌ范围，乳化液浓度对极压性能影响甚微。
Based on the friction tests, effects of the oil - soluble rare earth additive on extreme pressure property of the oil carboxylic - acid copper additive and zinc dialkyldithiophosphate (T202) have been analysed.
通过磨擦试验,研究了稀土添加剂对油溶性羧酸铜与二烷基二硫代磷酸锌(T202)极压性能的影响,结果表明:油溶性羧酸铜对T202的极压性能有显著影响,T202与较高剂量铜剂复合后最大无卡咬负荷明显降低;稀土添加剂与铜剂、T202以适当比例复合,有利于极压性能提高。
