Mineral oil and synthetic oil exactly what's different?
Various USES of lubricating oil, is by the viscosity of base oil of different levels with different proportions of several kinds of additive modulation and become. Mineral oil and synthetic oil the main difference is that different base oil. Mineral base oil is oil refining process, the fractionation out useful light material, such as aviation fuel, gasoline, etc), the left bottom of residual oil and refined.Nature, for its part, is to use less components of crude oil, crude oil contain a mixture of thousands of different molecules, even fine refining technology, also can't to bad content, impurity removal. In contrast, the synthetic oil base oil, gas from crude oil in the gas or gas dispersed ethylene, propylene, then through polymerization, catalysis, such as the chemical reaction of heavy and complicated is refined into large molecules composed of base oil.In essence, it is used in the crude oil better ingredients, chemical reaction and through the people under the control of the desired molecular form, its molecular order, natural ability to resist external variables is very strong, so synthetic oil quality is good, the thermal stability, oxidation reaction, strong ability to resist the viscosity changes of natural than mineral oil.In addition to the above, mineral oil in the distillation process could not be will contain impurities removed completely, so the high pour point, not suitable for frigid zone. And synthetic oil because do not contain impurities, the pour point of below 50 ℃ below zero. Such as aircraft, spacecraft, submarine meet climate temperature difference, is to use synthetic oil.
