‌Graphite: A magical assistant for self-lubrication of copper sleeves/copper plates

In the field of mechanical manufacturing, Zhejiang Mingxu Machinery Manufacturing Co., Ltd. has won wide recognition in the industry with its more than ten years of professional experience in self-lubricating bearings, copper sleeves, wear-resistant plates, automotive guide sleeves and other copper alloy accessories. Behind this, graphite, a unique carbon material in nature, plays an irreplaceable role as a key lubricating material with its excellent physical and chemical properties.

‌1. The layered structure and self-lubricating mechanism of graphite‌
Graphite has a unique crystal structure, consisting of stacked layers of carbon atoms, with weak interlayer bonding, which makes it easy for graphite to slide along the layer when subjected to external force. This feature provides a solid foundation for the self-lubrication of Zhejiang Mingxu's copper alloy accessories. In accessories such as copper sleeves and wear-resistant plates, graphite particles are cleverly embedded in the friction interface to form an extremely thin lubricating film. This lubricating film not only reduces the friction coefficient, but also reduces the heat and wear generated by friction, thereby achieving the effect of self-lubrication and improving the service life and performance of accessories.

‌2. Adsorption of graphite and protection of friction surface‌
Graphite has good adsorption properties and can adsorb water and gas molecules. These molecules act as "lubricants" between graphite layers, further reducing the friction coefficient. At the same time, graphite can also adsorb impurities and wear particles on the surface of copper sleeves/copper plates to prevent them from damaging the friction surface. This adsorption not only protects the friction surface, but also extends the service life of copper sleeves/copper plates.

3. High temperature resistance and chemical stability of graphite‌
Graphite has excellent high temperature resistance and can maintain its lubrication properties even in high temperature environments. This is crucial for copper sleeves/copper plates that need to work under high temperature conditions. In addition, graphite also has good chemical stability and can resist corrosion from acids, alkalis and organic solvents. This chemical stability allows graphite to maintain its lubrication effect even in harsh working environments, providing reliable protection for copper sleeves/copper plates.

‌4. Synergistic effect of graphite and copper‌
Graphite and copper have good compatibility, which allows graphite to be evenly distributed in the copper sleeve/copper plate to form a stable lubrication system. At the same time, the addition of graphite also improves the mechanical properties and wear resistance of copper sleeves/copper plates, making them more stable and reliable when subjected to heavy loads and impacts. This synergistic effect makes graphite an indispensable part of the self-lubrication of Zhejiang Mingxu's copper alloy accessories, and also wins a good reputation for its products in the market.

In short, graphite plays an important role in the self-lubrication of Zhejiang Mingxu Machinery Manufacturing Co., Ltd.'s copper alloy accessories with its unique layered structure, adsorption, high temperature resistance and chemical stability, and synergy with copper. It not only reduces the friction coefficient and wear rate, but also protects the friction surface and extends the service life of the accessories.
