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: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:Where is the graphite electrode scrap?

Vortex ring formed in a highly ionized internal ICP can be regarded as the secondary coil of the transformer is only one turn, and the work coil water is equivalent to the primary winding of the transformer, the coupling between them, the strength and direction of the magnetic field varies with time, the electronic and ionic field acceleration continuously changes its direction of motion. Lead to Joule heating effect and incidental ionization. This gas forms a new and stable "electric flame" light source in the quartz torch tube in a very short time.

Q:Classification of graphite electrodes

A graphite electrode that allows current densities greater than 25A/ cm 2 is allowed. Mainly used in ultra high power steelmaking arc furnace.

Q:Synthesis techniques of carbon nanotubes

The synthesis techniques of carbon nanotubes are mainly arc method, laser ablation (Zheng Fa) method, catalytic cracking or catalytic chemical vapor deposition (CCVD), and directional control growth method based on various synthesis techniques.

Q:What is the difference between SGL graphite electrode and graphite electrode in general?

Pure graphite is a kind of high-purity graphite. The processing technology of fine graphite and high purity graphite is basically the same, that is, the purity of graphite is different, the purity is higher, and the particle size is basically the same

Q:What's the use of carbon?

Common power graphite electrode. Allows the use of current density of less than 17A/ cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, yellow phosphorus and other ordinary power furnace.

Q:How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done

Infeasible!Iron plating is not easy because two - valent iron is not well - controlled with ferric ironGenerally, metal plating with multivalent States is not well controlled

Q:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?

The structure of the electrolytic cell is different when the electrolytic cell is constructed with different electrolytes

Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?

In addition, the infiltration of water on graphite is not good, can not get the effect of dust removal. Now there are special graphite machine, sealing system. Air-cooled can be used, after all, the best air-cooled.
