Industrial lubricating oil development trend and filtration and purification equipment selection
Development trend of lubricating oil
With the development of lubricating oil compounding technology, base oil has accounted for 95% or even 98% of the finished lubricating oil, so the performance of base oil will greatly affect the performance of lubricating oil. The technical requirements of lubricating oil for base oil in the future mainly include the following 6 directions:
① Good stability of thermal oxidation. Prolonging the life of lubricating oil, prolonging the oil change period and reducing consumption are all outstanding requirements for the thermal oxidation stability of base oil. This is especially true for lubricants used in high-efficiency internal combustion engines that produce high temperatures, as well as for gear oils, hydraulic oils and general lubricants. According to experience, the oxidation rate of lubricating oil will double for every 10 degrees Celsius increase in temperature.
② Low volatility. Low volatility of base oil is required to prolong the service life of lubricating oil and ensure that the quality of lubricating oil does not change significantly during service. Environmental protection also limits the volatility of base oils. Therefore, the volatility of base oil is required to be further reduced.
③ High viscosity index. The requirements for lubricants to function fully over a wide range of temperatures while maintaining a roughly constant viscosity have increased and will continue to do so. The best way to achieve this requirement is to use a high viscosity index base oil instead of relying on viscosity index improvers, because the viscosity index improvers will make the oxidation stability of lubricating oil worse and form deposits.
④ Low sulfur or no sulfur. Sulfur in mineral base oils is a natural extreme pressure additive and antioxidant, but sulfur can interact with additive compounds and make it difficult to optimize additive formulations. In addition, sulfur has a negative effect on the removal of nitrogen oxides by catalytic converter, so it is not desirable to contain sulfur in the base oil.
(5) Low viscosity. Reducing viscosity helps improve internal combustion engine efficiency. In addition, it is necessary to reduce viscosity when lubricating oil is required to have better fluidity at low temperature.
⑥ Environment friendly. The precondition for the continued use of petroleum base oils in the 21st century is to further reduce the content of aromatic hydrocarbons, especially polycyclic aromatic hydrocarbons, and also to ensure that the processing or recycling of base oils will not cause special problems affecting human health.
For full-loss lubricants and lubricants used in environmentally sensitive areas, in addition to the requirement of non-toxicity in water and on the ground, biodegradability will also be put on the agenda, and more and more attention.
