Q:The difference between graphite electrode and graphite rod: The difference between an electrode and a rod is that the electrode has a lead conductor, and the rod is not.

Q:The reason why graphite is used as electrode: The graphite has good conductivity and thermal conductivityThe conductivity of graphite is one hundred times higher than that of ordinary non-metallic minerals. Heat conductivity exceeds steel, iron, lead and other metal materials. The coefficient of thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, the graphite becomes hot.

Q:In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them: Graphite is characterized by coarse particles, fine particles and ultrafine particlesFor different processing, you can choose different particles, the smaller the particle size, the higher the accuracyCopper has good conductivity and thermal conductivity and is used in many occasionsBut there are many factors to consider in the choice between the two

Q:Why should graphite paper be placed between the heater and the graphite electrode?: Determine the thickness of the graphite bowl, the thickness of the graphite bowl is generally 3 mm -6 mm, three, determine the diameter of the heater, according to the diameter of the crucible and the thickness of the graphite bowl, calculate the inner diameter of the heater. The gap in the quartz crucible diameter phi = +2 times is +2 times the wall thickness of stone bowl bowl and graphite heater if the graphite bowl wall thickness is a, graphite bowl gap and heater for B (b=5 mm), phi = Phi Phi +2a+2b= within the outer crucible outer crucible +2 (a+b) four, to determine the effective heater the height after practice, the effective length of the quartz crucible heater is high 1.6 to 1.8 times.

Q:Electrolysis of CuCl2 solutions with graphite electrodes: After energization, electrolysis occurs, not ionizationIonization does not require energization, and can occur in aqueous or molten state.

Q:Graphitized anode, cathode and graphite electrode, respectively How can one differentiate and use differently?: In an electrolytic cell, the current from a class called graphite anode plate into the electrolyte electrolysis industry, the anode is made of plate shape, so called graphite anode plate, widely used in electroplating, wastewater treatment, industrial anti-corrosion equipment or special materials.

Q:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?: The temperature is not enough, the composition of graphite is carbon, of course, flammable, but each kind of object burning point is not the same, the nature of graphite is relatively stable, burning point is very high, cigarette lighter this temperature is certainly not burning up.Useful words, remember to adopt Oh, thank you ~!

Q:Do electroplating experiments, graphite as an electrode, graphite how to pre process to ensure that the coating will not fall, resulting in increased color of the solution: Use a tight filter cloth as an anode pack

Q:Synthesis techniques of carbon nanotubes: Catalytic pyrolysis is one of the widely used methods for preparing carbon nanotubes. The method mainly uses transition metal as catalyst, and is suitable for large-scale preparation of carbon nanotubes. The content of carbon nanotubes in the products is higher, but the defects of carbon nanotubes are more.

Q:What kinds of carbon are there?: Graphite electrode class can be divided into ordinary power graphite electrode according to the allowable current density. High power electrode and ultra high power electrode.
