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:What is Teflon graphite stick for?
Should be called graphite modified (reinforced, filled) PTFE bar, rod profiles are used for processing fine size parts. The material is made from polytetrafluoroethylene and reinforced with graphite reinforcing agent (or carbon fiber).
Q:Are the black powders in the waste batteries poisonous? And zinc, graphite and so on
Lead and lead compounds, can cause headache dizziness and insomnia, trance, fatigue, irritability easily angered, and accompanied by joint pain and nerve function disorder, mild anemia, trembling fingers may.
Q:What is the difference between a graphite wand, a drawing pencil and an ordinary Chinese painting pencil?
Graphite is an allotrope of elemental carbon is the most soft conductive minerals. Graphite and its products have the properties of high temperature resistance and high strength. Graphite can be used as a pencil core, pigment, polishing agent. After special processing, graphite can be made of various special materials for industrial departments.The main part of the pencil core is graphite. In fact, the pencil is made from a mixture of graphite and clay at a certain proportion. Such as "H" or "hard" English (hard) on behalf of the prefix, content of clay, pencil hardness to said. The bigger the number in front of the H (such as 6h), the harder the pencil core, the greater the proportion of clay in the cartridge to the graphite, the less pronounced the word, and is often used to duplicate.
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: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.
Q:What kind of sketch do you want, Shi Mobang?
Do you have to use a graphite stick? I can't draw a picture without drawing it. I can still draw it
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: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:Bought a high pure graphite stick, how so hard?! Doesn't it say that graphite is soft? Why is it so hard?
Of course, pure graphite rod is one of the main indicator is the strength and hardness of soft graphite refers to graphite can be used to write a relatively soft, you say should be soft flexible graphite, it is a kind of graphite,
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!
