Although the density of carbon fiber is lower than that of aluminum, its strength is higher than that of steel. Carbon fiber is not only the inherent "hard" characteristic of carbon materials, but also the machinability of textile fiber. A carbon fiber woven graphite felt has good conductivity, mechanical properties, electrochemical reaction activity, acid resistance, corrosion resistance and oxidation resistance, is a good electrode material, compared with metal, graphite powder and various electrode materials, more suitable for the electrode storage battery. At present, the domestic production of graphite felt is mainly used to make thermal insulation material, and its conductivity and electrochemical activity can not meet the requirements of the use of battery electrode materials, therefore, the need for carbon…
The high thermal conductivity graphite sheet has good thermal conductivity of 800-1900W/MK, it is perfect heat conduction material , it’s made from the new film materials after 3500 degrees Celsius high temperature sintering , it’s light and it’s 1/3-3/4 times of aluminum, 1/5-1/4 times of copper , these high thermal conductivity graphite sheet is easy to processing, it can be bent repeatedly and cut to any shapes. The properties of high thermal conductivity graphite sheet : high thermal conductivity, 1900W/m-K (X-Y axis), 15W/m-K (Z axis); high forming temperature , stable and reliable performance, no aging problem; good flexibility performance, easy to cutting, installation and use; it’s flexible and has light weight and high EMI shielding effectiveness; it meet the EU…
Pyrolytic graphite is a new type of carbon material, it is the high crystallinity pyrolytic carbon under the high pure hydrocarbon gas in the furnace pressure and one the graphite matrix which is in 1800 DEG C to 2000 C through the chemical vapor deposited, it has a high density (2.20g/cm), high purity (impurity content is 0.0002%) and the heat, electricity ,magnetism and mechanical properties anisotropy . The vacuum degree of 10mmHg can still be maintained at about 1800 DEG C. Pyrolysis is the process of decomposition of a substance by heat. The decomposition reactions will occur when many inorganic substances and organic matter are heated to a certain degree .The pyrolysis process does not involve the reaction of the…
