The high and low temperature resistance of dry film lubricant first provides stable protection for the operation of equipment in extremely high temperature environments. In industrial scenarios such as metallurgy and casting, equipment is often in a high temperature environment of several hundred degrees Celsius. Traditional lubricants are easily oxidized and decomposed due to high temperature, losing their lubricating effect, resulting in increased wear of components. However, dry film lubricant can maintain chemical stability at high temperatures. The solid lubricating film formed by it will not melt or volatilize due to temperature increase, and it will continue to provide isolation protection for the surface of components, reduce the friction coefficient, and ensure that key components such as gears and bearings can still operate smoothly under high temperature conditions, avoiding equipment failures caused by lubrication failure.
In extremely low temperature environments, this temperature resistance also plays an important role. For example, in cold chain logistics and polar scientific research equipment, the temperature may be as low as tens of degrees below zero Celsius. Traditional liquid lubricants will increase their viscosity suddenly due to low temperatures, or even solidify, resulting in difficulty in starting the equipment and increased operating resistance. Dry film lubricant will not undergo significant changes in physical state at low temperatures, and its lubricating film still has good toughness and adhesion, which can effectively reduce the friction resistance of components in low temperature environments, ensure the flexibility of equipment during low temperature startup and operation, and reduce energy loss and mechanical damage caused by poor lubrication.
High and low temperature resistance can also significantly improve the reliability of equipment in environments with drastic temperature fluctuations. Some outdoor equipment or industrial assembly lines may experience large temperature changes from high temperature during the day to low temperature at night. Traditional lubricants are prone to stratification and loss under the action of temperature alternation, and the lubrication effect is unstable. With its excellent temperature resistance, dry film lubricant can still maintain the integrity and uniformity of the lubricating film when the temperature fluctuates repeatedly, and will not fall off or crack due to thermal expansion and contraction, ensuring that the equipment is always in a good lubrication state in complex temperature changes, and reducing the equipment failure rate caused by temperature fluctuations.
For extreme environment equipment involving safe production, the high and low temperature resistance of dry film lubricant is the key to ensuring safe operation. In the fields of petrochemicals, aerospace, etc., the equipment operating environment is not only extremely hot, but also may contain flammable and explosive dangerous substances. If traditional lubricants evaporate or leak due to high temperature, they may cause safety accidents such as fire and explosion. However, dry film lubricant has no obvious volatiles at high and low temperatures, and will not drip due to temperature changes. It reduces the safety hazards caused by lubricating materials from the source and provides a safety barrier for production operations in extreme environments.
This high and low temperature resistance can also effectively extend the service life of the equipment. In extreme temperature environments, the thermal expansion and contraction of components will aggravate wear. If lubrication is not in place, it will accelerate the aging and failure of components. The continuous and effective lubrication of dry film lubricant at high and low temperatures can reduce the hard friction between components, reduce abnormal wear caused by temperature changes, and delay the fatigue aging rate of components. At the same time, the lubricating film formed by it can also isolate impurities such as moisture and dust, provide additional protection for metal surfaces in extreme environments, reduce corrosion, rust and other problems, thereby extending the overall service life of the equipment and reducing the frequency of equipment replacement and maintenance.
The high and low temperature resistance of dry film lubricant has broadened its application scope in special industry scenarios. For example, in the field of aerospace, when a spacecraft flies in the atmosphere, it will generate high temperature due to air friction, and after entering space, it will be in an extremely low temperature environment. Dry film lubricant can adapt to this extreme temperature difference and provide stable lubrication for the mechanical parts of the spacecraft; in geological exploration, equipment deep underground in high-temperature strata or polar ice layers can also rely on its high and low temperature resistance to maintain normal operation, which enables dry film lubricant to meet the stringent needs of more special industries and expand the application boundaries of lubricating materials.
In addition, high and low temperature resistance can also reduce the maintenance cost of equipment in extreme environments. Traditional lubricants need to be replaced frequently to ensure the lubrication effect at extreme temperatures, which not only increases the consumption of lubricants, but also requires downtime for maintenance operations, affecting production progress. However, dry film lubricant, with its high and low temperature resistance, greatly extends the lubrication life in extreme environments, significantly shortens the replacement cycle, and reduces the number of maintenance times and lubricant usage. At the same time, its stable lubrication effect reduces the wear rate of components and the need for spare parts replacement, thereby reducing the operating and maintenance costs of equipment in extreme environments from multiple dimensions and improving the economic benefits of the enterprise.
