Performance of Viscosity Index Improver
Viscosity index improver is a kind of oil soluble polymer compound, which is generally rubber like or solid at room temperature. It is the main additive used to prepare multi-stage internal combustion engine oil, hydraulic oil and Gear Oil. Adding viscosity index improver to lubricating oil can obtain multi-stage oil with good starting performance at low temperature and proper viscosity at high temperature, improve lubricating oil performance and improve lubricating oil grade Second, extend the service life of lubricating oil, and make the oil universal in all seasons.
The reasons why VII viscosity index improvers are paid attention to are as follows:
1.Improve the viscosity and temperature properties of oil products: The internal combustion engine oil, gear oil and hydraulic oil prepared with VII have good low-temperature starting and high-temperature lubricity, can meet the requirements of multi viscosity level at the same time, and can be used in all seasons.
2.Save fuel
Compared with single-stage oil, multi-stage oil can reduce the oil consumption of lubricating oil and fuel oil.
3.Reduce wear Because the viscosity temperature performance of multi-stage oil is smooth, and the change range of viscosity with temperature is smaller than that of single-stage oil, enough viscosity can be maintained at high temperature to ensure the lubrication of moving parts, thus reducing wear; the viscosity at low temperature is smaller .than that of single-stage oil, making it easy to start, thus saving dynamic force.
4.Simplified oil products
It can realize the generalization of oil products. For example, the universal towing oil can be used as the engine oil, gear oil, transmission oil and brake oil of tractor at the same time.
The performance of viscosity index improver mainly includes: shear stability, viscosity increasing ability, low temperature performance, etc. viscosity has decisive significance for lubrication. The high temperature viscosity of multi-stage oil is to measure the kinematic viscosity at 100 ℃ by capillary viscometer with low shear rate.
