Lubricating Oil Additives
1.1 Lubrication (Rizvi, 2009) The principle of supporting a sliding load on a friction reducing film is known as lubrication (Ludema, 1996). The substance of which the film is composed is a lubricant, and to apply it is to lubricate. These are not new concepts, nor, in their essence, particularly involved ones. Farmers lubricated the axles of their ox carts with animal fat centuries ago. But mo...
متن کاملSeparation & Identification of Organic Compounds in Lubricating Oil Additives Using TLC &GC-MS
Thin layer chromatography (TLC) and Gas Chromatography-Mass Spectrometry (GC-MS) techniques are proposed for qualitative analysis of lubricating oil additives (Hitec 2915). The additives were dissolved in heptanes, extracted with mixed solvents heptane: acetonitrile (3:2) and spotted on TLC paper. The best combination solvents as developer for TLC analysis were carbon tetrachloride: heptanes (9...
متن کاملDielectric behavior of electroactive fluorinate-based terpolymers
The dielectric and ferroelectric properties of the poly~vinylidene fluoride–trifluoroethylene– chlorotrifluoroethylene! terpolymers are studied in the temperature range 160–380 K. More attention was given to the dielectric loss in the dielectric spectra and the following results were obtained: ~1! there are two dielectric polarization mechanisms, modes A and B, contributing to the majority of t...

15 صفحه اولLubricating Oil Pollution Detection Sensor Design
Metal abrasive particle content in lubricating oil is an important index to judge the degree of deterioration of lubricating oil. Established a spiral electrode capacitance sensor by the finite element software ANSYS, the simulation result shows that the sensor is sensitive to the content of metal abrasive particle in lubricating oil, not affect by the metal abrasive particle itself. According ...
