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.
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 ...
Synthetic oleamide has a variety of industrial uses, including as a lubricant. [16] Oleamide was found to be leaching out of polypropylene plastics in laboratory experiments, affecting experimental results. [17] Since polypropylene is used in a wide number of food containers such as those for yogurt, the problem is being studied. [18]
Fun fact: K-Y Jelly, one of the most popular lubricant brands on the market, was created in 1904 and used not for sex, but as a surgical aid. When people did catch on that this jelly could be used ...
Grease (lubricant), a type of industrial lubricant; Grease, any petroleum or fat (including cooking fat) that is a soft solid at room temperature Brown grease, waste vegetable oil, animal fat, grease, etc. that is recovered from a grease trap; Yellow grease, in rendering, used frying oils, or lower-quality grades of tallow
