Formation of sediment in used industrial oil. Effect of temperature and solvent
Precipitation of sediment caused by external factors-temperature and solvent-is due to the spin nature of the contaminants formed during use of the oil. These paramagnetic contaminants also lead to aging of oils. Their total elimination restores the properties of used oil to the level of the base oil, but requires sufficient energy effects.
