Graphite Block

We can supply various sizes of graphite blocks with high strength(50~100Mpa) high purity(99.99%)and high density(1.8~1.90g/cm3). It has the properties of fina grains, uniform structure, and it is typically used as the construction materials of nuclear reactor, the heater of vacuum furnace and high-frequency furnace, the crucible and mould ofr melting metals, the internal lining of reduction furnace, mechanical sealing ring in the erosive medium and industry ambiance.

Q: Is graphite rod resistant to sulfur corrosion?: It is widely used in petroleum, chemical, hydrometallurgy, acid and alkali production, synthetic fiber, paper making and other industrial sectors. It can save a great deal of metal materials.

Q: Not that the solid does not conduct electricity, like the solid potassium chloride, but why the graphite rods, wires, these solids can conduct electricity: Because the graphite conductive graphite to each carbon atom and other carbon atoms form 3 covalent bonds, each carbon atom retains 1 free electrons to transfer charge. A metal dielectric wire, a free electron metal dielectric micro, conductive!

Q: What is the difference between the conductive effects of different grades of graphite? Refers to the pencil core: 2B first draft, and then use the 2H~8B tone. HB is the pencil hardness of B H--HARD concentration, B--BLACK density number is more soft black pencil, H number is more hard color the more light was.HB. The main component of the pencil core is graphite. In fact, the pencil lead is by graphite and clay made by blending.

Q: Carbon fiber nylon bars differ from graphite rods: A carbon fiber conductive nylon nylon belongs to, is to add carbon fiber in nylon material. The carbon fiber component determines the strength and conductivity of the material. The conventional addition of 30% carbon fibers can reach 10 of the 3-6 sides, belonging to the conductive products. In addition, carbon fiber in addition to conductive, but also can play a wear-resistant role, the intensity will be greatly improved.

Q: Why is there no graphite rod in battery five now?!: The most common alkaline battery in the market is zinc manganese dioxide battery, which is mainly composed of manganese dioxide. The following is the schematic diagram of its structure. ?You can go to the electrical store to buy a battery, there are graphite rods, it is still very thick.

Q: How good is the conductivity of graphite and the conductivity of copper?: It's copper. Copper resistivity is 10 negative, 8 times only after silver, and graphite resistivity magnitude is negative 6 timesGraphite rods are used in dry cells because they are stable in electrolytes, free of corrosion and low in industrial cost

Q: Bought a high pure graphite stick, how so hard?! Doesn't it say that graphite is soft? Why is it so hard?: High pure graphite rod belongs to artificial graphite is processed by tar pitch coke and the like, through the press, after N N in the baking leaching intensity, hardness increased, high purity graphite, graphite electrode made of graphite mould etc..

Q: What kind of sketch do you want, Shi Mobang?: Instead, it is the lead, and use the pencil almost, but it is not like a pencil with a wooden package, is a core bare, so it is easy to break, the price is not expensive... The beginner is recommended to use the pencil lead is difficult to master the appropriate

Q: 25%, the fracture of graphite rod, pressing problem or sintering problem?: 25% of the filling, 40 feel a little lower, and personally recommend using 50MPa. How long have you been under pressure? Suggest 20-30 minutes. Release the pressure a little slower, it will crack soon. Sintering, the insulation point does not need so much, 340, 320, recommended insulation for 4 hours. Also suggest that you do not put too many blanks in a furnace, it is better to cover in the middle, rough heating and heat dissipation will have an impact.

Q: How many times will a high pure graphite stick turn red at temperature?: With the increase of temperature, the oxidation rate is increased, if the nitrogen protection, can reduce the oxidation rate, so some high temperature furnace, vacuum furnace and vacuum extraction is to prevent the oxygen in the air oxidation of graphite, McNair to answer your questions.

We strictly follow the modern testing standard, such as ISO3069 standard, DIN24960 JB/T41271. It is for this reason that we has built a strong reputation in the market for it quality products. We always insist on building strong and long term relationship with our customers.We are willing to make persistent efforts to seek common development and create the future with friends from all over the world!
