The machining quality of the graphite plate influences its service life directly.It must be processed carefully to reach the standard indicators. it must be uniform such as dipping, the resistivity must be consistent, it also can avoid a part is intact and another part is serious corrosion in the production process so that the total body waste down. It is the key to make a good use environment to prolong the service life of graphite anode plate. In the production process, reduce the impact, keep the working environment clean, detect the circuit on time and organizing the production at a fixed temperature, reduce the degree of oxidation of the air. The Matters needing attention for prolonging the service life of…
Carbon / carbon - silicon carbide composite material is carbon fiber reinforced carbon and silicon carbide ceramic matrix composite material , it appears in early 1980s as the thermal structure of materials with low density, good oxidation resistance, corrosion resistance, excellent high temperature mechanical properties and thermal physical properties, good self-lubricating performance and other advantages, it is a new high temperature structural materials and functional materials which can be used in the 1650℃. As the brake disk material , the carbon / carbon - silicon carbide composite material not only has the advantages such as carbon disk density is small, stable brake wear, the rate of weight loss is small and large heat capacity , but also it overcome the…
Graphite felt has good stability, the unit cost of large surface area, good permeability of the advantages of electrode materials used in direct methanol fuel cell flow, but because of its poor hydrophilicity, electrochemical activity is not high, which greatly limits its application. Therefore, we try to improve the electrochemical properties of carbon atoms by changing the electronic structure of carbon atoms. Although the nitrogen doped graphite felt has been reported sporadically, the research on the nitrogen doped graphite felt used as the cathode of direct flow methanol fuel cell is still in the blank. With the energy and environmental problems become more and more prominent, the research and development of green, pollution-free new energy has been attached great importance…
