Introduction
The High-purity Graphitized Petroleum Coke is made from high quality petroleum coke under a temperature of 2800°C. As a high-purity carbon material, it has characteristics of high fixed carbon content, , low porosity, high absorptive character , no residue will be left and save production cost etc.
This product can be used as carbon raiser (Recarburizer) to produce high quality steel, special steel, cast iron and alloy or other related industry. We can get high quality steel if use it. It can also be used in plastic and rubber as an additive.
Features
The graphitized petroleum coke powder (grain) is made by graphitization heat treatment of high-quality low-ash petroleum coke at high temperature of 2800 ° C or above in vacuum. The product is featured by high carbon content, low hardness, high temperature resistance, large porosity and low heat conductivity coefficient. Compared with the traditional natural graphite and calcined coke, it can obviously improve caking property and stabilize friction coefficient, maintains the stable and comfortable braking process, and reduce the damage to mating plate surface, brake noise, wear and cost, and is an ideal material for the friction material plant.
In order to control the package and quality, we send people to inspect the loading at loading port and take samples for third party inspection for everyshipment, and will keep customers updated about the loading condition and the inspection result.
Graphite petroleum coke is used in producing casting, it can increase the used quantity of Scrap steel and reduce the quantity of Scrap iron, or use no Scrap iron at all, graphite petroleum coke has high absorptive character, no residue will be left, save production cost.

- Q: What are the hazards of inhalation of graphite dust?
- The main pathological change was two lung was black, the whole lung has isolated or clusters of small black nodules around the bronchioles and small blood vessels, irregular nodules; around focal emphysema, pleural thickening and adhesion. X - ray was mainly manifested in increased lung markings, with fine mesh fabric and fine nodular shadows, coarse mesh progression increased, often associated with emphysema, China has listed as the occupation scope of carbon black pneumoconiosis disease.
- Q: The principle of a graphite missile
- Graphite conducts graphite on the wire to short-circuit the circuit
- Q: What effect does graphite powder and graphite gas have on people? Also, I smell graphite gas as if I can't breathe. What's the harm to people?
- This is determined by the quality of the graphite powder. Graphite workers in our factory are equipped with masks to prevent dust. (formerly, Shandong, South villa, graphite mine) more than 5000 state-owned enterprises, workers have worked for 20-40 years, and has yet to find too much harm to the body. Pay attention to dust protection measures.
- Q: Know how the colloidal graphite powder comes in
- There are two ways to make colloidal graphite: (1) mechanical method. Natural graphite is crushed and treated with hydrochloric acid and hydrofluoric acid to remove impurities. Added to the aqueous solution of tannic acid, which is repeatedly inverted into paste. Colloidal graphite can be obtained by adding a certain proportion of water and ammonia, and then by ultrasonic treatment to further reduce the particle size. (2) chemical method. After being purified and crushed, the natural graphite is added with concentrated nitric acid and concentrated sulfuric acid and water at 90 DEG C, and then obtained by cleaning, drying, adding water, ethanol, acetone and other dispersing agents to obtain colloidal graphite. Add stabilizer such as sodium oleate, sulfate and so on, so that graphite particles do not agglomerate. Ammonia transfers the graphite colloid to the gum solution and regulates the pH value.
- Q: How much is the price of graphite powder for a ton?
- Qingdao Chenyang graphite is China's Graphite brand-name products, strong technical force, perfect measuring and testing, quality assurance system.
- Q: What solvent can be used to dissolve Teflon?
- PTFE is not dissolved after Teflon, it is impossible to mix with graphite powder this thing.
- Q: How to distinguish between iron powder, aluminum powder and graphite powder (pencil core powder), there are two ways
- Method three: in reverse order with method(1) take a little powder and add dilute hydrochloric acid respectivelyIf bubbles are produced and green light is generated, the solution is iron powder (chemical equation Fe+2HCl = FeCl2+H2)The reaction is more intense, there are more bubbles, the color of the solution does not change, it is aluminum (chemical equation 2Al+6HCl = 2AlCl3+3H2)No obvious phenomenon is graphite powder (not reaction)(2) if the difference between the bubble phenomenon is not obvious, then two kinds of powder with magnetCan be the magnet is not attracted by the permanent magnet is iron powder; powder(high school can also use NaOH solution to identify iron aluminum, aluminum reacts to dissolve hydrogen, iron does not respond)
- Q: Crystal graphite of graphite powder
- Pure graphite flake graphite and high directional pyrolytic graphite, which have less defects and larger sizes, can generally be considered as perfect graphite single crystals. Considerable research has been done on the thermal conductivity of such graphite. Under compressive stress, the pyrolytic graphite above 3000K processing, the bulk density is 2.25g/cm, 2.266g/cm is close to the theoretical density of the single crystal, the half width of the diffraction peak (002) show only 0.4 degree angle (mosaic angle), is also very close to the theoretical value of zero. The thermal conductivity of this graphite is shown in table 1. These values are generally considered to represent the corresponding values for single crystal graphite. The thermal conductivity along two principal directions is denoted as lambda a along the layer, and is marked by lambda C along the vertical plane.
- Q: Influence and protection of graphite dust on electrical equipment in workshop
- The graphite dust in the workshop is conductive, and the adhesion to the electric apparatus will affect the electrical insulation and lead to accidents. So we need to have the electrical box of graphite dust workshop to closed treatment, to prevent dust into the electrical cabinet.
- Q: Refractive index and absorbance of graphite powder
- When the matter to be measured is different, or the wavelength chosen is different, the molar absorption coefficient will be different, so that it can not meet the quantitative relationship of Bill's law.
