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 sulfur, low ash, 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.

FAQ
1, Usage: used to improve the Carbon content in steel-melting and Ductile iron foundry
2, Characteristic: high carbon, low sulfur, with stable effect for improving the carbon content, high absorptive of carbon. It is more and more popular in this filed.
3, apply: Used in electric furnace steel smelting and cast-iron for improving the carbon content
- Q: Can you tin to latex paint
- Can not brush metal thermal expansion and contraction principle is very strong, or how long it will fall off, really want to brush with a small nail unless many small eyes in atoms in the metal, and then dust coat paint brush
- Q: How many kinds of lubricating graphite powder can be added to the car engine?
- The scale and rust in the water tank are not very strong. It is a little growth. Graphite powder added, good dispersion, destroy the growth condition of scale and rust, no longer changxin. Then, have grown in water flow, under agitation, a little bit is washed down, and can no longer stick back, then, are in the water.
- Q: How can the clinker graphite powder be dissolved in water?
- To achieve this purpose many methods; the titanate coupling agent and silane coupling agent is used in simple water dispersion system of the surface modification, hydrophilic group will make Shi Mofen (film) dispersed in water while stirring under shear stress.
- Q: Graphite powder screening process, because with static holding together, resulting in vibration screen plugging network how to solve?
- The other is to install an electrostatic eliminator when the material falls into the vibrating screen. When the material is dropped, the powder static electricity is removed and the mass will not be assembled again.
- Q: What graphite powder made of graphite products, high hardness?! Wear-resisting！ Good moisture! It can be made into graphite products at 100-200 degrees high temperature
- 100~200 C is not called high temperature for the preparation of carbon graphite products, but only resin can be prepared at this temperature.
- Q: The difference between silicone and silicone?
- The characteristics of silicone grease:The application of silicone grease is more widely than silica gel. Many industrial heat places are using thermal grease. Many different types of people and grease, by adding some "impurities" to its thermal conductivity to improve pure thermal grease. These impurities are graphite powder, aluminum powder, copper powder, silver powder and so on. Pure pure silicone is pure white or milky white, the color of the doped graphite grease dark black, doped with aluminum grease some gray shiny, slightly gray is silver, and copper doped grease are yellow or yellow.Now some high-grade thermal grease using silver or aluminum powder as filler, with high thermal conductivity of the metal, but relatively large metal particles, filling effect is poor, the performance increase is not large, but the improper use of conductive grease, easy to cause a short circuit.
- 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: Can graphite powder be used as a carburizing agent?
- Basically can be, but to look at your purity, if many impurities can not be used if the carburant is a general term, is all can increase the carbon content of the material referred to a molten iron, graphite powder is then dust too much, when the operation is not clean, too small it is easy to burn and water oxidation, not good,
- Q: How can graphite paper be made? Can graphite powder be solidified without brittleness?
- Process for the preparation of graphite paper: high carbon flake graphite, graphite by chemical processing into acid (also known as graphite oxide or expandable graphite), in high temperature 960 to 980 DEG C for a few seconds, the level of the graphite lattice moment along the C axis expansion, a fiber floc type vermicular graphite. The expanded graphite is very soft, the roller for the rolling forming, expanded graphite and flexible graphite sheet or foil sheet.
- Q: Does graphite allow lubrication of rusted doors?
- Into the rusty iron graphite powder can play the role of lubrication, graphite powder can open the door locks rust.
