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?: The corrosion resistance of graphite with good thermal conductivity, low permeability, can be used for the production of heat exchanger, reactor, condenser, combustion tower, absorption tower, cooler, heater, filter and pump equipment.

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: Since there is no moving charge in potassium chloride crystals, it naturally cannot conduct electricity. Potassium chloride in molten water and in molten state, because of the free movement of chloride and potassium ions, it can conduct electricity

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?!: Because of the size of battery 5, but not with graphite rods, what specific use, and then wait for an expert

Q: Bought a high pure graphite stick, how so hard?! Doesn't it say that graphite is soft? Why is it so hard?: The graphite is soft, refers to natural flake graphite powder, rather than artificial. Try some natural flake graphite powder.

Q: What is the difference between a graphite wand, a drawing pencil and an ordinary Chinese painting pencil?: Any painting, as far as tools are concerned, any material will do. The above problem is how we understand the properties of these materials, with a pencil. For example: 2H, HB, 2B, 3B, 4B, 5B, 6B, 7B,,,,, this is a pencil mark label, B number is more and more soft, and will draw more and more black. The smaller the number of B, the more hard, though graphite is a material of the pencil, but with this painting.

Q: Copper, graphite rods, dilute sulfuric acid, why not make up the original battery?: Because there is no oxidant, and can not react with dilute sulfuric acid, and if the graphite rod in the vicinity of the continuous access to oxygen, you can form the original battery

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?: When the temperature reaches 400 degrees, the graphite turns red and then begins to oxidize, but the oxidation rate is slow.

Q: What about the thermal conductivity of graphite rods?: Its thermal conductivity is not only more than steel, iron, lead and other metal materials, and with the rise in temperature, thermal conductivity decreases, which is different from the general metal materials, at very high temperatures, graphite and even tend to adiabatic state.

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!
