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...

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی بیان شده اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...
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 ...
متن کاملEffects of High–oil Corn and Soybean Oil Additives
Aerial dust originating from feed is a major contributor to poor air quality in swine confinement buildings. Studies have shown that addition of fats and oils to swine feed reduces its dustiness. The objective of this study was to evaluate the effectiveness of several high–oil corn (HOC) varieties on reducing aerodynamic dust segregation (ADS) as compared with conventional or normal corn (NC) a...
