SC9-4和棕榈油的比较分析研究

SC_9-4是以植物油为原料研制成功的一种高速冷轧工艺润滑油。经武钢高速冷轧机轧制性能鉴定,它的高速轧制性能优于棕榈油。我们使用高效液相色谱比较分析鉴定了SC_9-4和棕榈油的甘油三酯组成。分析结果:SC_9-4:的主要甘油三酯是POP(42.8％)和PPP(14.6％),而棕榈油的主要甘油三酯是POP(31.3％)、POO(20.1％)、PLP(12.2％)和PLO(11.6％)。我们初步探讨甘油三酯组成与轧制性能关系认为,SC_9-4的高速轧制性能优于棕榈油,可能是和SC_9-4含PPP、PPS和PSS的含量(18.8％)高于棕榈油(9.9％)有关。

A STUDY ON THE COMPARATIVE ANALYSIS OF SC_9-4 AND PALM OIL

SC9-4, a technical lubricating oil for high speed cold strip rolling, is made from vegetable oils. After the test in the high speed rolling mill of Wuhan lron and Steel Works, it was confirmed that SC9-4 was better than palm oil for high speed rolling. The triglyceride compositions of SC9-4 and palm oil were analysed by HPLC. The main triglycerides of SC9-4 were POP (42.8%) and PPP (14.6 %), while those of palm oil were POP (31.3%), POO (20.1%), PLP (12.2%) and PLO (11.6%). The relationship between triglyceride composition and the property of lubricating oil was discussed. The authors explained that the better property of SC9-4 was due to its higher content of saturated triglyceride (18.8%), whereas the content of saturated triglyceride of palm oil was 9.9%.
