The roles of PTFE micropowder in lubricating oils and greases primarily include enhancing lubrication performance, improving wear resistance, increasing oil film strength and load-bearing capacity, as well as exhibiting excellent high-temperature resistance and chemical corrosion resistance.
When added as an additive to lubricating oils and greases, PTFE micropowder can significantly improve the high-pressure and high-temperature lubrication properties of the materials. Even in cases where the base oil is lost, it can still function as a dry lubricant and self-lubricant. Additionally, PTFE micropowder can increase the viscosity of the oil. Typically, the addition amount ranges from 5% to 30% (by weight), depending on the viscosity of the base oil, the desired consistency of the lubricant, and the application area.
The specific application effects of PTFE micropowder in lubricating oils and greases include:
Enhancing Lubrication Performance: PTFE micropowder provides stable lubrication under high-temperature and high-pressure conditions, maintaining the soft consistency of the grease even in extreme environments.
Improving Wear Resistance: PTFE micropowder significantly enhances the wear resistance of lubricants, thereby extending their service life.
Increasing Oil Film Strength and Load-Bearing Capacity: PTFE micropowder generates a high-concentration lubricating protective layer, enhancing the strength and load-bearing capacity of the oil film, making it suitable for use in heavy-load equipment.
High-Temperature and Chemical Corrosion Resistance: PTFE micropowder possesses excellent high-temperature resistance (ranging from -300℃ to 340℃) and can resist acid and alkali chemical corrosion, making it suitable for use in high-temperature environments.
These characteristics make PTFE micropowder widely applicable in high-temperature and heavy-load equipment such as ball bearings, wear-resistant bearings, high-temperature furnaces, and automatic welding equipment.
The recommended addition ratio of PTFE micropowder in lubricating oils and greases typically ranges from approximately 5% to 30% (by weight). However, please adhere to actual application requirements.
