Research and application of high temperature nano graphite filler

High-Temperature Nano-Graphite Gland Packing is a high-performance sealing material that is mixed with nanoscale graphite powder and other auxiliary materials and processed through a special process. Due to its excellent thermal stability, lubricity and chemical resistance, it exhibits excellent sealing effects in many high temperature environments. The special structure of nanographite gives it better performance than traditional graphite, allowing it to maintain efficient sealing performance under high temperature, low friction, and long-term operation conditions.

Characteristics of high temperature nano graphite filler
High-temperature nanographite filler has the following significant characteristics:

Excellent high temperature resistance: Nanographite materials can withstand extremely high temperatures up to 3000°C, and can maintain the stability of their physical and chemical properties in high temperature environments.
Low friction coefficient: Nanoscale graphite particles can effectively reduce the friction coefficient, thereby reducing equipment wear and energy consumption.
Excellent chemical stability: Graphite itself has excellent acid resistance, alkali resistance and corrosion resistance, and can adapt to harsh chemical environments.
High strength and sealing: The structure of nanographite filler enables it to maintain good sealing performance under high pressure and high temperature, preventing liquid or gas leakage.

Research progress of high-temperature nanographite fillers
In recent years, with the development of nanotechnology, new breakthroughs have been made in the preparation process and application research of nanographite. Researchers continue to improve nanographite's performance in high-temperature environments by adjusting its particle size, surface treatment and composite material selection. The following are several key research developments:

Optimization of nanographite particles: By controlling the particle size and surface morphology of graphite particles, its ability to combine with other materials can be significantly improved, and its sealing performance and high temperature resistance can be enhanced.
Composite of nanographite and other materials: For example, the composite of nanographite and corrosion-resistant materials such as polytetrafluoroethylene (PTFE) can further improve the compressive strength and chemical corrosion resistance of graphite fillers.
Self-lubricating properties: The self-lubricating properties of nanographite enable it to reduce friction during the sealing process and extend the service life of the equipment. It is especially suitable for high-temperature and high-speed working environments.
