Under high - temperature and high - load working conditions, high - viscosity dimethyl silicone oil (above 500cst) has many remarkable advantages, making it an ideal choice for such working conditions.

• Form a stable lubricating film: High - viscosity dimethyl silicone oil can form a thicker and more stable lubricating film on the metal surface. In a high - temperature environment, the viscosity of ordinary lubricating oil is likely to decrease, and the lubricating film becomes thinner, greatly reducing the lubrication effect. However, high - viscosity dimethyl silicone oil, by virtue of its own characteristics, can still maintain a relatively thick lubricating film even at high temperatures, effectively separating the metal surfaces and avoiding wear caused by direct contact, providing lasting and stable lubrication protection for equipment.
• Powerful load - bearing capacity: Facing high - load working conditions, the metal components of equipment bear huge pressure. High - viscosity dimethyl silicone oil has a stronger load - bearing capacity and can effectively disperse the pressure, preventing surface damage caused by excessive local pressure. For example, in the transmission systems of large - scale heavy - duty machinery, high - viscosity dimethyl silicone oil can form a tough lubricating layer on key parts such as gears and bearings, ensuring the stable operation of the equipment under high - load operation and reducing the probability of failures.
• Good thermal oxidation stability: High temperatures can accelerate the oxidation and deterioration of lubricating oil, reducing its lubrication performance. High - viscosity dimethyl silicone oil has excellent thermal oxidation stability. It is not easy to undergo oxidation reactions in a high - temperature environment, can maintain its physical and chemical properties for a long time, extend the oil change cycle, and reduce maintenance costs.
• Effectively buffer vibrations: During high - load operation, equipment often generates vibrations and impacts. High - viscosity dimethyl silicone oil has certain damping characteristics and can absorb and buffer these vibration and impact energies, reducing damage to equipment components, improving the operation stability of the equipment, and extending the overall service life of the equipment.

In summary, under high - temperature and high - load working conditions, high - viscosity dimethyl silicone oil provides reliable protection for the stable operation of equipment with its unique performance advantages and plays a key role in many industrial fields.
