Inflation can reach above 200 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
