What are the key performance indicators of lubricating oil emulsifiers?
The key performance indicators that determine the emulsification effect and application value include: maximum shear rate: the core indicator of emulsification capacity, usually 50000-150000 s⁻¹, which directly affects the fineness of oil-water droplets and the stability of the emulsion. Viscosity adaptation range: the range of lubricating oil viscosity that the equipment can handle, usually 10-1000 mPa·s (40℃), and high-viscosity lubricating oils require emulsifiers with higher torque.Emulsion particle size control accuracy: the ability to control the average particle size of the emulsion, usually 0.1μm-10μm, and the particle size distribution should be uniform (polydispersity index PDI ≤ 0.2). Temperature control range: since lubricating oil viscosity is sensitive to temperature, the equipment usually has a temperature control function of 20-80℃ to adjust the viscosity of the oil phase and improve emulsification efficiency. Continuous operation stability: the ability to operate continuously for a long time (8-24 hours) without performance degradation, which is crucial for industrial mass production. Material compatibility: compatibility with various lubricating oil additives (e.g., emulsifiers, rust inhibitors, antioxidants) without affecting the emulsification effect or chemical properties of the additives.
