The subway track system is a high-risk area where passengers are strictly prohibited from entering. Besides the high-speed running trains, the high voltage electricity present in between is also a fatal danger source. Some people who are not familiar with it may wonder, do the rails carry electricit
The mission of the pantograph is to maintain contact with the overhead contact line to supply power to high-speed trains. It presses against the contact line with a certain pressure to ensure the stability and continuity of power transmission. The contact surface of the pantograph is made of graphit
Graphite powder refers to the powder state of graphite material, with a particle size of 60 mesh to 2000 mesh. According to the source, it is divided into natural graphite powder and artificial graphite powder. Graphite powder has the characteristics of graphite material: high temperature resistance, corrosion resistance, good electrical conductivity, good lubrication, etc.
Specific uses include:
Graphite powder can be used as conductive materials, such as in the electrical industry to manufacture electrodes, brushes, carbon tubes, carbon rods, and TV picture tube coatings.
Graphite powder can be used as refractory materials, such as pressed silicon carbide graphite crucible, and steel ingot protective agent.
Graphite powder can be used as lubricants and wear-resistant materials in the machinery industry, such as brake pads.
Graphite powder can be used for mold release and metallurgical materials in metallurgical casting.
