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
This graphite will eventually wear out, even if you use the nickel plate directly, the nickel plate is still wearing, but compared to graphite than the much better. You should ask the question, the brush plating industry association, oh, they study this stuff all day long.
Q:Does the silicon carbide heat plant require a fine structure graphite electrode? What kind of graphite products do you need?
But because the silicon carbide is too hard, it is difficult to machining, good workability, such as non special requirements, using graphite instead of silicon carbide, instead of the effect is not good, but can use a silicon carbide, easy processing, small life than silicon carbide.
Q:National standard for graphite electrodes
Page 7 the international standard specifies the shape, dimensions and tolerances, technical requirements, test methods, packaging, marking, storage, transportation and quality certificates of graphite electrodes. This standard applies to high quality petroleum coke, asphalt, coke as the main raw material, through molding, roasting, impregnation, graphitization and mechanical processing made of, power supply arc furnace as conductive material of ordinary power graphite electrode. Common power graphite electrode GB
Q:Why is graphite conductive electrode oxidized?
Graphite electrode uses petroleum coke (carbon), pitch coke (carbon) as granule material
Q:How long is the graphite electrode machining cycle?
The dust produced in the processing of graphite electrode is relatively large, the possible intrusion to the machine tool guide screw and spindle, which requires a corresponding machining device of graphite graphite dust machine, sealing better, because the graphite toxic.
Q:Classification, uses and manufacturers of graphite electrodes
Classification of graphite electrodes:(1) common power graphite electrode (RP), (2) high power graphite electrode (HP), (3) quasi ultra high power graphite electrode (SHP), (4) ultra high power graphite electrode (UHP) Note: poly carbon classification method
Q:Is the anode of electrolytic water suitable for ordinary titanium wires?
Graphite firstFirst of all, the titanium electrode is usually not pure titanium, it should be titanium with a metal oxide coating. Secondly, the advantages of the titanium electrode is mainly to save electricity, the corrosion resistance of carbon is much stronger than that of industrial production, if the meaning is relatively large, but it is still in laboratory experiments, electrolysis of water, not what meaning.
Q:The difference between graphite electrode and graphite rod
Graphite rod for non metal products, as carbon arc gouging cutting process in an essential pre welding cutting supplies, is composed of carbon and graphite with appropriate adhesive, through the extrusion, the temperature of 2200 DEG C after baking rotary plating a layer made from copper, high temperature resistance, good electrical conductivity, is not easy fracture, suitable for metal cutting into required shape.
Q:What are pyrolytic graphite electrodes used for?
The weight is lighter: the density of graphite is only 1/5 of copper. When the large electrode is used for EDM, it can effectively reduce the burden of machine tools (EDM). It is more suitable for applications on large moulds.
Q:Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?
Graphite here acts only as an electrode, and the real reaction on the graphite is oxygen, the galvanic cell reaction called iron oxygen corrosion
