The process of graphite impregnation is to fill the pores of carbon graphite materials with different forms of carbon. The purpose of the dense and impregnated graphite impregnation process is to produce high density products, High density of liquid penetration. However, the densification is limited, it is impossible to require all the pores of dense products, but only A layer that is not dense enough for the product. Deposited on the surface of the graphite carbon covered layer, can significantly change the performance of another, because The deposited carbon layer becomes another working surface. The characteristics of the dense carbon layer will be described below. Two, the need to dip the product of 1 small size graphite electrode and joint…
The graphite felt is normally classified into asphaltic based graphite felt, PAN based graphite felt &rayon-based graphite felt. The mainly application is electric conduction in the photovoltaic industry, as the heat retaining material, thermal insulation material for the smelting furnace and vacuum furnace, and in chemical industry it could be the filtration material. The carbon/ graphite felt is made of oxidized PAN short cut fiber. And after opening, carding, lapping, needling,it is made into a certain density and thickness. Some excellent performances such as high purity, soft texture, No dus and chemical corrosion resistance will be obtained by special carbonization and graphitization process .The carbon/graphite felt can improve the current density of the liquid flow battery, and it has the…
The carbon fiber (carbon fiber, referred to as CF) is a new kind of fiber material with high strength and high modulus fiber with carbon content of more than 95%. It is a flaky graphite, micro crystalline and other organic fibers stacked along the axial direction of the fiber, it is obtained by carbonization and graphitization of micro crystalline graphite material. the quality of the carbon fiber is lighter than aluminum, but the strength is higher than that of steel, and it has the characteristics of corrosion resistance, high modulus, it’s important materials in the national defense and civilian areas . It has not only the intrinsic characteristics of carbon materials, but also the softness and processability of textile fibers.…
