1) Physical and chemical properties
The physical and chemical properties of the lubricant is the lubricant must have the performance, these properties are indispensable. If the lubricant does not have these properties, it can not play a lubricating effect.
The physical and chemical properties of the lubricant is to determine the basis of its performance, and is determined by its molecular composition. Therefore. To determine whether a lubricant is in line with the use of a certain mechanical requirements, clover first must be tested for its physical and chemical properties. In a variety of lubricants in the standard is mainly on the physical and chemical properties of the requirements of the test, the physical and chemical properties of lubricants have been basically standardized test methods, and basically can be common with each other. As the physical and chemical properties of lubricants on the choice and use of lubricants have a great impact, so we have to introduce the physical and chemical properties of lubricants in detail.
Usually we divide the physical and chemical properties of lubricants into three categories
a: the physical properties of lubricants
b: chemical properties of lubricants
c: the use of lubricants performance
1) Physical properties of lubricants
Including viscosity, viscosity index, density, refractive index, color, relative molecular mass, water absorption, surface tension, anti-foaming, air release, anti-emulsification, mechanical impurities, compression and so on.
