In addition to industrial applications, lubricants are used for many other purposes. Other uses include cooking ( oils and fats in use in frying pans and baking to prevent food sticking), to reduce rusting and friction in machinery , through the use of motor oil and grease , bioapplications on humans (e.g., lubricants for artificial joints ...
Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives , detergents, dispersants , and, for multi-grade oils, viscosity index improvers .
A bottle of glycerin purchased at a pharmacy Personal lubricants commonly contain glycerol Glycerol is an ingredient in products such as hair gel Glycerol suppositories used as laxatives. Glycerol is used in medical, pharmaceutical and personal care preparations, often as a means of improving smoothness, providing lubrication, and as a humectant.
A sample of synthetic motor oil. Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil, but can also be synthesized from other raw materials.
K-Y Jelly was initially used as a surgical lubricant before it gained popularity as a personal lubricant. [citation needed] Lignocaine gel containing the local anaesthetic lignocaine is a prime example of a non-irritating substances used as surgical lubricant [citation needed] Medicinal castor oil was the original vegetable-based surgical ...
"The industrial lubricant market is entering a new phase of growth, driven by the convergence of technological innovation, sustainability initiatives, and the expansion of industrial activities. With the increasing focus on reducing energy consumption and operational costs, we expect the demand for high-performance and eco-friendly lubricants ...
Hanouneh cautions, however, that it is important to address the underlying cause of constipation rather than rely on laxatives, which can lead to dependency and cause the body to become less able ...
Due to the strong coupling between lubricant hydrodynamic action and the elastic deformation in contacting solids, this regime of lubrication is an example of Fluid-structure interaction. [4] The classical elastohydrodynamic theory considers Reynolds equation and the elastic deflection equation to solve for the pressure and deformation in this ...
