Maybe you have noticed Isostatic Graphite or Artificial Graphite. You think both of
them are unique and incredible. Then let us know more about graphite.
As some of us know, graphite is with its unique
nature. Isostatic Graphite is a great example.
In other words, graphite has unique structure as a result it has its special
function.
Firstly,graphite is with high temperature
resistance. Generally speaking, graphite‘s melting point can be up to 3
thousand, nine hundred degrees. At the same time, its boiling point can be up
to 4 thousand, two hundred and twenty 5 degrees. Even the ultra high
temperature arc ignition, weight reduction of graphite continues to be
extremely small. What‘s much more, its coefficient of thermal expansion is also
very small. In contrast, the graphite strength increases using 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 become specific, graphite is with 1 hundred occasions greater
conductivity than that of general nonmetal ore. As a matter of reality, it‘s
thermal conductivity can be more than that of steel, iron, lead as well as
other metal supplies. But around the other hand, its thermal conductivity
decreases using the increase of temperature. Even in high temperature, graphite
may be as insulator. Graphite can conduct electrical energy because every
carbon atom in graphite forms three covalent bonds with other carbon atoms.
What‘s more, each carbon atom still retains one free electrons to charge.
Thirdly, grahite is with great lubrication. To be
particular, its lubrication overall 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
performance will be.
Fourthly, graphite is with great chemical
stability. Graphite has good chemical stability at room temperature. As a
result, it is with acid, alkali and corrosion resistance to organic solvents.
Now, let us discuss 1 application of graphite.
Graphite can be utilized as wear resistant
lubricating material. Usually speaking, graphite, in the mechanical business,
is frequently used as lubricant. As all of us know, the lubricating oil can not
be utilized in the condition of higher speed, higher temperature and higher pressure.
But in contrast, graphite‘s wear-resistant material may be used in the
temperature of two hundred to two thousand degrees and without lubricating oil.
As for a lot of devices that transport the
corrosive medium, Graphite Heater is widely used
for creating piston cup, sealing ring and bearings. That is because once they
run, there's no need to add lubricant.
