There is no doubt that Graphite Crucible could
be created by Graphite Producer. But to begin with, graphite producer must know
how to purify the grahite. If you are interested in it, why not join me to
discuss it right here right now? You'll be able to know more than before.
That's for certain.
As some of us know, within the approach of
chemical purification, the concentration of NaOH is about fifty percent of we
mix the graphite and NaOH with the proportion of 1:0.eight. That is to say if
we have to make a single ton high Carbon Graphite, we
need to consume NaOH about 0.four ton. Simultaneously, the addition of HCl is
about thirty % of graphite. What?¡¥s a lot more, the fuel coal must be about
0.6 ton to o.7 ton.
Determined by the above motives, the
chemical purification for graphite need a greater expense. As a way to resolve
the above issues, we have to create new technology of high Carbon Graphite purification. To become
distinct, we can use centrifugal washing as an alternative to V sort washing
tank. What?¡¥s more, we are able to do treatement to wastewater and attain
recycling. Utilizing this new technologies, the material expense could be
decreased about fifty %. And simultaneously, we are able to save water about
fifty percent. What?¡¥s far more, the increasing on the yield might be up to
ten percent. Essentially the most important issue is the fact that we can also
reduce the pollution in the waste water towards the environment.
Simultaneously, the carbon content material of graphite can be greater than
ninety nine % and also the recovery rate can be ninety two point eight %.
Now let us talk about physical
purification, which can be also named high-temperature purification. As a
matter of truth, physical purification makes great use of graphite?¡¥s
high-temperature resistance nature. To become specific, we must place the
graphite in the furnace (which might be referred to as Graphite Heater) and
make the graphite isolate with air. Soon after that, we need to heat the air
for the temperature of two thousand and five hundred degrees Celsius. Within
this way, we can make the ash (ie impurities) volatile. As a result, we are
able to enhance the grade of concentrated ore. In other words, High Purity Graphite
with purity of ninety nine point nine % can be obtained from high temperature.
That's why Graphite Heaters
belong to very crucial equipments to acquire High Purity Graphite.
