Perhaps you have seen Isostatic Graphite or Artificial Graphite. You think both of
them are special and amazing. 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 unique structure consequently it has its
unique function.
Firstly,graphite is with high temperature
resistance. Usually speaking, graphite‘s melting point may be up to three
thousand, nine hundred degrees. At the same time, its boiling point can be as
much as 4 thousand, two hundred and twenty 5 degrees. Even the ultra higher
temperature arc ignition, weight reduction of graphite continues to be very
little. What‘s much more, its coefficient of thermal expansion can also be
extremely small. In contrast, the graphite strength increases using the growing
temperature. By the way, when the temperature of graphite is two thousand, the graphite
intensity may be doubled.
Secondly, graphite is with the feature of
conductivity. To become particular, graphite is with one hundred times greater
conductivity than that of common nonmetal ore. As a matter of fact, it‘s
thermal conductivity can be over that of steel, iron, lead as well as other
metal materials. But around the other hand, its thermal conductivity decreases
using the increase of temperature. Even in higher temperature, graphite can be
as insulator. Graphite can conduct electrical energy because every carbon atom
in graphite forms three covalent bonds with other carbon atoms. What‘s much
more, every carbon atom nonetheless retains 1 totally free electrons to charge.
Thirdly, grahite is with good lubrication. To be
specific, its lubrication performance depends upon the size of graphite flake.
In other words, the larger the flake or Graphite Block is, the smaller sized
the friction coefficient will probably be, and also the better the lubrication
performance will probably be.
Fourthly, graphite is with good chemical
stability. Graphite has great chemical stability at space temperature.
Consequently, it's with acid, alkali and corrosion resistance to organic solvents.
Now, let us talk about 1 application of graphite.
Graphite may be utilized as put on resistant
lubricating material. Usually speaking, graphite, in the mechanical business,
is often used as lubricant. As all of us know, the lubricating oil can not be
used within the condition of high speed, higher temperature and high stress.
But in contrast, graphite‘s wear-resistant material can 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's simply because when
they run, there's no need to add lubricant.
