The graphite electrode is mainly made from the petroleum coke and needle coke, coal tar pitch as the binder, after calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, it is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, it can be divided into ordinary power, high power and ultra high power according to the quality index level. Graphite electrodes has compact and even structure, good electric conduction and heat-conducting properties, high mechanical strength and strong oxidization corrosion resistance at high temperature through calcination, intermediate crushing, screening, dosing, mixing, compression, roasting, high pressure impregnation, graphitization, machining and other processes, it is widely used for arc furnaces…
The graphite products have good adsorption. Carbon pore structure makes carbon have good adsorption, so carbon is often used as adsorbent material for adsorption of water, odor, toxic substances and so on. We have done the experiments, a few days before the barbecue pan graphite used looks very clean, but in the electromagnetic oven heating, we will see the last barbecue oil and the adsorption of harmful substances will slowly leaking, but don't worry, with a clean kitchen paper to wipe clean can use. Graphite products have good thermal conductivity, fast heat transfer, uniform heating and fuel saving. A baking pan made of graphite, such as a pan, is heated quickly, and the burned food is evenly heated, cooked from…
HOPG, Highly Oriented Pyrolytic Graphite is a new kind of carbon material with high purity. It is a new kind of carbon material prepared by pyrolysis of graphite at high temperature and high pressure. Its properties are close to that of single crystal graphite. To study X applications include X-ray monochromator, neutron filter and graphite monochromator, basic properties, large size, high thermal conductivity of graphite intercalation compounds and application in the field of application. The monochromator can provide a reusable smooth surface for microscopic analysis personnel. Unlike mica, HOPG is completely nonpolar, suitable for elemental analysis, and has only carbon background signals in the analysis. HOPG has excellent surface smoothness so that it can be used as a blank background…
