Core Functions of Barium Petroleum Sulfonate

1. High-efficiency anti-rust and anti-corrosion agentThis is the most core and widely used function of barium petroleum sulfonate. When added to lubricating oils, cutting fluids, or greases, it can adsorb firmly on the surface of metal components to form a dense, oil-soluble protective film. This film effectively isolates the metal from corrosive media such as moisture, oxygen, and acidic impurities generated during fuel combustion, preventing rusting of steel parts and corrosion of non-ferrous metals such as copper and aluminum. It is particularly suitable for protecting internal combustion engines, gearboxes, hydraulic systems, and metal processing workpieces during storage and operation.
2. Detergent and dispersant for lubricating oilsBarium petroleum sulfonate can act as an auxiliary detergent-dispersant in engine oils and industrial lubricants. It can disperse the oil sludge, carbon deposits, and metal wear particles generated during the operation of equipment into the lubricating oil system, preventing these harmful substances from depositing on the surface of key components such as piston rings, cylinder walls, and oil passages. This function helps maintain the cleanliness of the lubricating system, improves the circulation efficiency of the oil, and extends the service life of both the lubricant and the mechanical equipment.
3. Extreme pressure and anti-wear additiveWhen compounded with other extreme pressure agents such as sulfurized olefins or phosphorus-containing additives, barium petroleum sulfonate can enhance the anti-wear and load-bearing capacity of lubricating oils. It participates in the formation of a chemical reaction film on the friction surface under high-load conditions, reducing friction and wear between metal components, and preventing seizure or scuffing of moving parts such as gears and bearings. This makes it an important additive component in heavy-duty industrial gear oils and hydraulic oils.
4. Additive for metal processing fluidsIn metal cutting, stamping, and drawing fluids, barium petroleum sulfonate serves as a key anti-rust and lubricating additive. It provides both temporary anti-rust protection for workpieces and tools after processing, and auxiliary lubrication during the processing process, reducing the friction between the tool and the workpiece, improving the processing accuracy and surface quality of the workpiece, and extending the service life of the cutting tool.
