Poly(methyl methacrylate) lubricant additives have extensive and significant applications in numerous fields. Here is a detailed introduction:
Automobile industry
Engine oil: In automotive engine oil, polymethyl methacrylate plays a crucial role as a viscosity index improver. It enables the engine oil to maintain good fluidity at low temperatures, ensuring that the engine oil can quickly reach various components when starting in cold weather, achieving rapid lubrication and reducing wear during the startup phase. Under the high-temperature conditions generated during normal engine operation, it can also maintain an appropriate oil film strength, ensuring stable lubrication between moving parts and helping to extend the engine's service life and enhance the overall performance of the engine.
Automatic transmission fluid: In automatic transmission fluid, polymethyl methacrylate can significantly improve its low-temperature fluidity, enabling the transmission to smoothly shift gears even in low-temperature environments and avoiding problems such as gear shifting delays. At the same time, it helps maintain the appropriate viscosity of the transmission fluid at different working temperatures, ensuring the normal operation of the hydraulic control system inside the transmission and the gears and other components, enhancing the smoothness of gear shifting and the overall efficiency of the transmission.
Industrial sector
Gear Oil: Among various types of gear oils used in industrial gear transmission devices, the addition of polymethyl methacrylate can enhance the anti-wear performance of the gear oil. By reducing the friction coefficient of the gears during meshing, it effectively reduces the wear of the gears, lowers energy loss, and improves the efficiency of gear transmission. Moreover, it can also enhance the carrying capacity of the gear oil, enabling it to adapt to higher loads and rotational speeds, ensuring the stable and reliable operation of the gear transmission system. It is commonly used in gearboxes of various industrial fields such as mining machinery, metallurgical equipment, wind power generation, etc.
Hydraulic oil: As an additive for hydraulic oil, polymethyl methacrylate helps to optimize the viscosity-temperature performance of the hydraulic oil, ensuring that the hydraulic oil maintains a relatively stable viscosity under different working temperature conditions. This enables more precise pressure transmission and more sensitive operation in the hydraulic system, effectively preventing system failures caused by excessive or insufficient viscosity of the hydraulic oil due to temperature changes. It is widely used in equipment such as construction machinery and injection molding machines that rely on hydraulic systems for operation.
Aerospace field
Aircraft engine lubricating oil: The working environment of aircraft engines is extremely harsh, and the performance requirements for lubricating oil are extremely high. Poly(methyl methacrylate) can optimize the low-temperature starting performance and high-temperature stability of aircraft engine lubricating oil, enabling it to maintain good lubrication and heat dissipation effects throughout the low-temperature conditions in the air and during frequent temperature changes such as takeoff and landing. This provides a strong guarantee for the reliable operation of the aircraft engine and plays a crucial role in ensuring flight safety.
Marine sector
Marine engine oil: Marine engines usually operate under high-load conditions for long periods of time, and the operating environment is complex and changeable. They also face many unfavorable factors such as seawater corrosion. Poly(methyl methacrylate) additives help marine engine oil better adapt to temperature changes, reduce the wear of engine components, and at the same time, can improve the oil's anti-emulsification performance, avoiding the emulsification of the oil due to the introduction of impurities such as seawater, which would result in the loss of lubrication effect and ensure the reliable operation of the marine engine. This is of great significance for the normal navigation of ocean-going vessels and ships engaged in offshore operations.
