The use of scales graphite and colloid graphite

Scales graphite is a very widely used non -metallic powder product, with good thermal conductivity, conductivity and lubrication effect; colloid graphite is a graphite product that uses natural scales graphite as the main raw material. There are certain differences in use. The following editor will introduce the purpose of scales graphite and colloid graphite:The scales graphite has a strong conductive capacity. It can replace the metal as a conductive material. The scale graphite can also be directly used as a carbon conductive filler or a composite conductive filler for conductive coating. The quality of scales graphite powder has a lot to do with its carbon content. Natural scales graphite collected from natural mines often contain a lot of impurities. It needs to be purified to get graphite powder with high carbon content because of high purity scales. The use of graphite is more widely used, providing an effective solution for the miniaturization and high integration of electroni

Graphite artificial synthesis

(1) Taking natural scales graphite as raw materials, use Hummers legal oxygen graphite, and use thermal peeling into graphene, or use ultrasonic dispersion to divert into graphene, and then chemically restore into graphene. Use SEM, TEM, HRTEM, XRD, and RAMAN systems to examine the appearance and structure of graphene.(2) Taking graphene as the basis, titanate tetraododes as titanium sources. First, the solution-water thermal legal system is used to prepare titanium dioxide/graphene nano-composite materials. Use XRD, SEM, TEM, and RAMAN to characterize the crystal structure, granular appearance and chemical composition of titanium dioxide/graphene nano -composite materials. The results show that the synthetic titanium dioxide nanocrystal is a sharp titanium structure, the crystalline condition is good, titanium dioxide and graphite The composite effect is better.

The main impregnating agents currently used for graphite

(1) Carbon based materials: Most carbon based materials use asphalt, but in order to control the filling rate, tar or asphalt is often mixed with low carbonization rate and low viscosity carbon based materials such as tar and creosote. They are carbonized through heat treatment after impregnation, so the residual material entering the pores is only carbon. The carbon process is currently a standard carbon process aimed at improving density, strength, conductivity, thermal conductivity, corrosion resistance, and wear resistance. It has become the most common treatment method for general carbon materials, especially in the production process of fine structured graphite and UHP electrodes for electric furnace steelmaking. It is an indispensable process. In order to achieve the same goal, there are also cases of impregnating synthetic resin and then roasting and carbonization. The carbonization of synthetic resin generally generates hard carbon, which is characterized by greatly increasin

Factors affecting the gasification reaction of carbon materials

(1) Degree of graphitization: As the degree of graphitization of carbon materials increases, their activity towards gases decreases. The higher the final heat treatment temperature of carbon materials, the higher the temperature at which they begin to oxidize, so graphite products have a higher starting oxidation temperature than carbon products.(2) Structural state: Carbon materials with loose and porous surfaces are prone to react with gases. For example, the surface dense pyrolytic graphite treated at 3200 ℃ begins to oxidize in air at a temperature of 850 ℃, while the porous and loose charcoal on the surface begins to burn at 360 ℃.(3) Catalytic effect of impurities: Carbon materials contain impurities that have a significant impact on their gasification reaction, with varying catalytic effects. For example, iron, cobalt, nickel, copper, manganese, etc. are catalysts for the oxidation of carbon materials, while impurities such as boron, titanium, and tungsten have inhibitory effec
