FAQ
What is the consumption of your Electrode？
The comsumption of Our Electrode can be below 1.0kg/mt, and the everage is 0.5kg/mt.
What is the reason of the problem of broken?
There are several reasons, such as: Amperage is too high, the connection is not good, etc.
- Q: Why is graphite conductive electrode oxidized?
- Coal tar pitch is a kind of high temperature resistant graphite conductive material, which is made of coal tar pitch as binder. It is made by calcination, crushing, mixing, kneading, forming, roasting, graphitization and mechanical processing. It is called graphite electrode
- Q: Electrolytic salt water why use iron as a cathode, all with graphite can not?
- From an economic point of view, the storage amount of iron is much larger than that of graphite, graphite iron is cheaper and easier to get.
- 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: Electrolytic water solution, two electrodes are graphite electrode, the negative electrode can produce large amounts of hydrogen, the anode does not produce half of oxygen, and only a small amount of it?
- The oxygen will react with the graphite and the gas will dissolve.The iron has been oxidized.
- Q: Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
- After calcined to eliminate ash and volatile part of the points in this process will be a lot of weight loss, in the process of crushing mixing in process of baking or graphite in high temperature heat treatment, another part of the impurities were excluded, so the raw material is higher than the rate of finished products.
- Q: Classification of graphite electrodes
- 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: 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
- Both of these will be a little bit absorbed, when plating, the anode and anode inside the syrup will run on the negative pole,
- Q: What do carbon products include?
- High power electrode and ultra high power electrode. The carbon block can be divided into blast furnace carbon block, aluminum carbon block and electric furnace block. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the depth of processing. Carbon products can be divided into graphite products, carbon products, carbon fibers and special graphite products according to the raw materials and the production process. Carbon products according to their ash content, and can be divided into multi gray products and less ash products (including ash below l%).
- Q: I used 12V direct current, graphite electrode electrolysis sodium sulfide solution, the anode produced a large number of black material, this is why ah?
- The problem is this. I have done the test of electrolytic copper sulfate, and the anode produced the same phenomenon. Finally, the chemistry teacher told me that it was because the graphite was broken in the process of electrolysis
- Q: What does graphite electrode GSK mean?
- Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
