Carbon / carbon composites are a new kind of high performance composite materials. It has a high ratio of strong, high specific modulus, high temperature resistance, corrosion resistance and a series of advantages, especially the retention rate of its excellent strength at high temperature, the high temperature in an inert environment of 2000 degrees Celsius, the intensity is not reduced, but increased, which is unmatched by other materials. According to the different materials used in matrix precursor, carbon / carbon composites are divided into CVI base and pitch base. Pitch based carbon / carbon composites have become a hot topic in the research of carbon/carbon composites due to its low price, short preparation period. Pitch based carbon / carbon composite…
Product Description: liquid aluminum alloy purification treatment process is the main means to improve the comprehensive properties of aluminum alloy. In the purification process, the purification gas and solvent mixture, the use of graphite rotor spinning jet to the aluminum melt purification method is currently the most advanced processing methods in the world. The working principle of the graphite rotor rotation of the rotor will be blown into the aluminum melt in nitrogen or argon) broken into a large number of dispersed bubbles, which are dispersed in the liquid metal. Bubbles in the melt by gas differential pressure and surface adsorption principle, absorption of hydrogen in the melt, adsorption oxidation slag, and with the rise of bubbles and was brought…
The graphite heater is the electric heating body parts which made of graphite materials. The Graphite has good electrical and thermal conductivity, and it is commonly used in special industrial furnace as a heating element. The graphite electrode was the heating body in the early selection of industrial furnace , and the high density and power electrode was used as heating element later (smelting quartz glass also used graphite electrode as the heating element). In semiconductor industry development and refining silicon, single crystal germanium, gallium, indium, indium and other materials,the high-purity graphite with fine structure and homogeneous graphite were used as graphite heating in the heating furnace . The carbon cloth or graphite cloth were useing in some special industrial…
