China Manufacturer +80 Mesh +100 Mesh High Carbon 98% Natural
Expanded Graphite Used in Machinery
Can be expanded graphite sheet expansion characteristics different
from other kinds of expansion agent, heated to a certain
temperature, due to absorption in interlayer matrix compound
decomposition, began to swell, expansible graphite as starting
expansion temperature, expansion completely in 1000 °C, the maximum volume. Inflation can reach above 200 times -300 times of the initial volume. After expansion of graphite is called expanded graphite or
graphite worms, the original scaly into low density worm-like,
formed a very good insulation blanket. Expanded graphite is a
carbon source in the inflation system, and thermal barrier, can
effective heat insulation, with in the fire heat release rate is
low, the quality loss is small, the characteristics of the produced
less smoke.
Expanded graphite is a kind of good performance of the adsorbent,
especially it has a porous structure, has strong adsorption
capacity for organic compounds, expanded graphite can be 1 g 80 g
of oil adsorption, thus expanded graphite was designed to all kinds
of industrial oil and industrial oil absorbents.
Expanded graphite extremely easy adsorption of oils, organic
molecules and hydrophobic substances, used for water environmental
treatment has irreplaceable effect to other substances. When it is
used for the surface oil removal in granular form, according to the
size of the water in oil area and the type of the oil, its dosage
is 1 ~ lo % / rn, adsorption time in 15 rain to several hours.
Compared with other sorbents, expanded graphite has many
advantages. If use activated carbon for water oil removal, it will
sink after adsorption of oil, the adsorption quantity is too small,
and not easy to recycle; And some adsorbent, such as cotton, hay,
polypropylene fiber, perlite, vermiculite and so on, they are on
the oil absorption of the water absorption at the same time, it
brings to the post-processing difficult; Expanded graphite on oil
adsorption quantity is large, floating in the water after oil
absorption, easy to catch recycling, recycling processing is
simple, can use extrusion, centrifugal separation, vibration,
solvent cleaning, burning and heating extraction method, and no
second pollution formed.
Features:
1) strong pressure resistance, flexibility, plasticity and self
lubrication;
2) of high and low temperature resistance, corrosion resistance,
resistance to radiation characteristics;
3) Strong seismic characteristics;
4) strong conductivity;
5) Strong anti-aging properties, resistance to distortion;
6) Can resist all kinds of metal melting and infiltration;
