Why Is Graphite So Special And Sensible In Our Daily Life?

Perhaps you've seen Isostatic Graphite or Artificial Graphite. You believe both of them are special and incredible. Then let us know more about graphite.

As a few of us know, graphite is with its unique nature. Isostatic Graphite is really a great instance. In other words, graphite has special structure as a result it has its special function.

Firstly,graphite is with high temperature resistance. Usually speaking, graphite‘s melting point may be as much as 3 thousand, nine hundred degrees. At the same time, its boiling point may be up to 4 thousand, two hundred and twenty five degrees. Even the ultra higher temperature arc ignition, weight loss of graphite continues to be very little. What‘s much more, its coefficient of thermal expansion is also very little. In contrast, the graphite strength increases with the increasing temperature. By the way, when the temperature of graphite is two thousand, the graphite intensity can be doubled.

Secondly, graphite is using the function of conductivity. To be specific, graphite is with one hundred times higher conductivity than that of general nonmetal ore. As a matter of reality, it‘s thermal conductivity can be over that of steel, iron, lead as well as other metal supplies. But on the other hand, its thermal conductivity decreases with the increase of temperature. Even in high temperature, graphite may be as insulator. Graphite can conduct electricity because each carbon atom in graphite forms 3 covalent bonds with other carbon atoms. What‘s much more, each carbon atom still retains one free electrons to charge.

Thirdly, grahite is with good lubrication. To be particular, its lubrication performance depends upon the size of graphite flake. In other words, the bigger the flake or Graphite Block is, the smaller sized the friction coefficient will be, and also the better the lubrication overall performance will be.

Fourthly, graphite is with good chemical stability. Graphite has good chemical stability at room temperature. Consequently, it is with acid, alkali and corrosion resistance to organic solvents.

Now, let us discuss 1 application of graphite.

Graphite can be utilized as put on resistant lubricating material. Usually speaking, graphite, within the mechanical industry, is frequently used as lubricant. As all of us know, the lubricating oil can not be used in the condition of higher speed, high temperature and high pressure. But in contrast, graphite‘s wear-resistant material may be utilized in the temperature of two hundred to two thousand degrees and with out lubricating oil.

As for many devices that transport the corrosive medium, Graphite Heater is extensively used for creating piston cup, sealing ring and bearings. That's simply because once they run, there is no have to add lubricant.
