How does a lubricating oil emulsifier differ from emulsifiers for food, cosmetics, or other industries?
The core difference lies in the adaptation to material characteristics and application requirements, mainly reflected in three aspects: material compatibility: lubricating oil emulsifiers are usually made of wear-resistant, corrosion-resistant materials (e.g., 316L stainless steel, tungsten carbide coatings) to withstand the wear of lubricating oil impurities (e.g., metal particles) and the erosion of additives (e.g., antioxidants, rust inhibitors), while food/cosmetic emulsifiers prioritize food-grade materials with no toxic residues. Shear force design: lubricating oil has high viscosity (usually 10-1000 mPa·s at 40℃) and high interfacial tension with water, so lubricating oil emulsifiers need to generate higher shear force (50000-150000 s⁻¹) to break down oil droplets, while emulsifiers for low-viscosity materials (e.g., food sauces, cosmetic lotions) have lower shear force ranges. Safety and hygiene standards: lubricating oil emulsifiers focus on equipment tightness and anti-leakage to avoid environmental pollution and equipment damage caused by lubricating oil leakage, while food/cosmetic emulsifiers must comply with GMP, FDA and other hygiene standards to ensure product safety. In addition, lubricating oil emulsifiers often integrate functions such as heating, cooling, and impurity filtration to adapt to the processing requirements of lubricating oil additives.
