Web27 dec. 2024 · $\begingroup$ Usually, no chemistry is involved. (Some) plastics may (partly) dissolve or swell in contact with organic solvents and also grease. This alters material properties, such as mechanical strenghth, optical appearance etc. This does not occur for all combinations of plastics and grease. $\endgroup$ – Grease is a solid or semisolid lubricant formed as a dispersion of thickening agents in a liquid lubricant. Grease generally consists of a soap emulsified with mineral or vegetable oil. A common feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops … Meer weergeven A true grease consists of an oil and/or other fluid lubricant that is mixed with a thickener, typically a soap, to form a solid or semisolid. Greases are usually shear-thinning or pseudo-plastic fluids, which means that the Meer weergeven Jointly developed by ASTM International, the National Lubricating Grease Institute (NLGI) and SAE International, standard ASTM D4950 “standard classification and specification for automotive service greases” was first published in 1989 by ASTM … Meer weergeven • Bearing (mechanical) • Lubrication • Lubrication theory Meer weergeven Grease from the early Egyptian or Roman eras is thought to have been prepared by combining lime with olive oil.
