FAQ
Why do the normal eletrodes existe broken situation?
There are several reasons, but two are more important:
a. The power is too high, and the electrode can't suport it;
b. The connection between two parts is not good.
- Q: How to solve the problem of graphite electrode being crushed during electrolysis
- There's no way. It's an industrial problem, and that's how graphite works.
- Q: What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water
- The reason is that the resistance increases continuously, the number of ions is limited, and the conductivity is limited
- 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: Graphite electrode specifications, graphite electrode manufacturers which good?
- The key is you use and what type of need, say, abroad, what Dongyang, sigley are good, but also, very expensive, you can also choose to try our home
- 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: National standard for graphite electrodes
- The national standard normal power graphite electrode graphite electrode: the standard name standard classification number Q51 Standard No. YB/T 4088-2000 for YB/T 4088-2000 YB/T 4088-1992 2000/12/1, instead of the execution time of 0:00:00 release time 2000/7/26 0:00:00 adoption situation
- Q: How does graphite produce solar cells?
- In addition, the Research Report of the first author, Massachusetts Institute of Technology Department of materials science and engineering postdoctoral Zhang Shenggen said, different from other semiconductor temperature has been rising continuously, the graphite electrode coating Zinc Oxide nanowires can be temperature controlled at 175 degrees celsius.
- Q: Graphite electrode press device
- Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.
- Q: How do graphitized electrodes differentiate between high power and low power?
- 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: How large is the permissible overload current per square millimeter of the graphite electrode cross section?
- 9A/mm2 safety current should be bare overhead, 5A/mm2 is obviously insulation lines, the indoor environment standards.
