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:Are the black powders in the waste batteries poisonous? And zinc, graphite and so on: Nickel and nickel salt can cause metal heat, pruritus and eczema. A series of nickel carbonyl can cause headache, dizziness, heavy hair, gait instability, nausea, vomiting, chest tightness and paralysis of the nervous system, severe irritation of the respiratory tract, cause pulmonary edema.

Q:25%, the fracture of graphite rod, pressing problem or sintering problem?: Agree to the above point of view, add a little pressure speed is not fast, in 25mm/min, the bad words too fast exhaust will cause cracking, transverse fracture from your description of the phenomenon, most are not caused by the row of clean air.

Q:What about the thermal conductivity of graphite rods?: The thermal conductivity and conductivity of the graphite rod are quite high. The conductivity of the graphite rod is 4 times higher than that of stainless steel, 2 times higher than that of carbon steel, and 100 times higher than that of ordinary nonmetal.

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: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:What is the difference between a graphite wand, a drawing pencil and an ordinary Chinese painting pencil?: Charcoal is the source of raw wood burning container was put into the seal, because the air can not enter the container, not wood burning down. Crunchy texture, porous charcoal, charcoal painting with hardness, very soft, soft, not soft not hard points.General charcoal are used to draft use, easy to modify, draw up very fast, so is generally not as deep drawing tools. The difference in the diameter of the charcoal strips is determined by the size and size of the paintings.

Q:Why is there no graphite rod in battery five now?!: Dry batteries are alkaline batteries (Alkaline battery), also known as alkaline batteries, is the application of alkaline electrolyte batteries, such as zinc manganese dioxide, zinc oxide (mercury) etc.. The most common alkaline batteries on the market the most common component is the former, zinc manganese dioxide battery, it using manganese dioxide as anode and cathode zinc, potassium hydroxide aqueous solution as electrolyte.

Q:What is the difference between the conductive effects of different grades of graphite? Refers to the pencil core: Such as "H" or "hard" English (hard) on behalf of the prefix, 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:What is Teflon graphite stick for?: Graphite can improve the wear resistance, thermal conductivity, self lubrication, electrical conductivity, heat resistance and deformation of polytetrafluoroethylene. With the application of high temperature resistance, wear resistance, corrosion resistance and other environments, in addition to food, insulation, oxidant environment, graphite modified (enhanced filled PTFE) can PTFE can be used instead of the original environment.

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..

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.
