CAS 7782-42-5 Foundry Carbon Graphite Chemistry Black Solid C24X12
Graphite is a crystalline form of carbon black, iron to dark gray.
Soft, creamy feel, conductive. Chemically inactive, corrosion
resistance, acid and alkali, etc. is not easy. To strengthen the
heat reaction in air or oxygen, combustible and generate carbon
dioxide. Strong oxidizing agent will be oxidized into it organic
acid. Used as anti friction agent and lubricating material, making
crucible, electrode, battery, pencil. High purity graphite in
nuclear reactor for neutron moderator. Often referred to as carbon
or graphite, because the former is mistaken for the lead.
YIXING SUNRISE COMMERCE CO.,LTD is the lead manufacturer and
exporter to have volume production of Triacetin series,which is
widely used in tobacco,food packing
material,foundry,medical,field,etc.We also provide other products
like PC(Propylene Carbonate),EGDA(Ethylene Glycol Diacetate),
FA(Furfuryl alcohol),which widely used in foundry industry.
Also,we have a series of products widely used as solvent in coating
and paints&ink industry,like IPAC(Iso-propyl
acetate),NPAC(N-propyl acetate),and SBAC(Sec butyl acetate)...
Our main market is in Europe,Japan,Korea,Australia,South Asia,etc.
with great capacity and quality of products we won customers' trust
and we aim at providing quality and products and better services on
a global basis.
1, For refractory material: graphite and its products with high
temperature properties, high strength, in the metallurgical
industry is mainly used to manufacture steel commonly used in
graphite crucible, graphite as the protective agent of steel ingot,
metallurgical furnace lining.
2, As a conductive material: used for manufacturing the electrode
in electrical industrial brushes, carbon, carbon nanotubes, anode,
mercury is converter graphite gasket, telephone parts, TV tube
3, For wear resistant lubricating material: graphite is often used
as a lubricant in the mechanical industry.
4,Graphite has good chemical stability, widely used in
petrochemical, wet metallurgy, acid and alkali production,
synthetic fiber, paper and other industrial sectors, can save a lot
of metal materials.
5, For casting, casting, molding and high-temperature metallurgical
material: Graphite due to thermal expansion coefficient is small,
and the capability of cold and hot change, can be used as a mold of
the glass, the use of graphite after black metal castings get
precise size, smooth surface, high rate of finished products, can
be used without processing or minor processing, thus saving a lot
6, For the atomic energy industry and national defense industry:
graphite has a good neutron moderator in the atomic reactor,
uranium graphite reactor is a more application of an atomic
7, Graphite can prevent boiler fouling, the unit test showed that,
in the graphite powder by adding a certain amount of water (about
4~5 grams per ton of water) to prevent the boiler scaling on the
surface of graphite. In addition to a metal chimney, roof, bridge,
pipeline can rust.
8, Graphite can be used as a pencil core, pigment, polishing agent,
graphite after special processing, can make a variety of special
materials for the relevant industrial sector.
9, Electrode: the advantage of the graphite electrode is the
processing speed is faster, the weight is lighter, the discharge
consumption is smaller, the material cost is lower, there is no
burr; and graphite is easier to grind and polish.
