In the field of lubricating oil, demulsifier is an important additive, its function is to prevent emulsification in lubricating oil.
A demulsifier is an additive that breaks up oil-water emulsions. In lubricating oil, demulsifiers use a certain principle of action to decompose the oil-water emulsion into two phases, namely the oil phase and the water phase, to facilitate oil-water separation.
In lubricants, the main application scenario of demulsifiers is in the lubrication system of mechanical equipment. For example, in a hydraulic system, oil and water can easily form an emulsion due to mechanical movement and fluid vibration. During the design process, the following aspects need to be considered:
Demulsifier activity: The most basic function of demulsifier is to destroy emulsion.
Compatibility: Demulsifiers should be compatible with the base oil as well as other additives to ensure proper operation of the lubrication system. In the future, the development trend of demulsifiers will be towards high efficiency, environmental protection and multi-functionality.
In addition, as people’s requirements for lubricating oil performance continue to increase, the development of multifunctional demulsifiers will also become an important research direction in the future.
