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 sulfur, low ash, low porosity, high absorptive character , no residue will be left and save production cost etc. it is playing more and more important role in the industry
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.

3, apply: Used in electric furnace steel smelting and cast-iron for improving the carbon content

Q: How does graphite powder solidify into a lump? What bond is best used?After solidification can be more than 1000 degrees high temperature does not change: The only way to do this is by using physical methods, high temperature and high pressure, to agglomerate the graphite powder from the molecular level. Now, by simulating the high temperature and pressure of the earth's crust, graphite can be turned into diamond (that is, diamonds)

Q: The graphite powder can replace thermal grease?: Graphite is non-toxic, but graphite powder is harmful to human body; and graphite is used mostly in conductive products (common battery).

Q: How to measure the conductivity of powdered graphite?: The conductive effect of graphite powder is an important factor in making conductive products, so it is very important to know the conductivity of graphite powder.Graphite powders have high electrical conductivity. And stone toner conductivity is an important factor in graphite powder conductive products. There are many factors affecting the conductivity of conductive graphite powder, such as the proportion of graphite powder, external pressure, humidity of the environment, humidity and even light.

Q: How to identify iron powder and graphite powder in a simple way?: Iron powder can be attracted by magnet, graphite powder can not; iron powder can react with acid, graphite powder can not wait, optional take first magnet attract, and then drip acid or hand touch method to identify two substances;

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: Graphite powder and resin mixing, molding, and then "high temperature" curing made graphite products, but the intensity of what will not be very high. Usually graphite products are not prepared directly with graphite powder, but with various kinds of coke, such as asphalt coke, petroleum coke, etc. the graphite products prepared by this method have high strength.

Q: Is graphite powder dangerous?: Will pour into the dry drying workshop, drying after bagging, namely ordinary graphite powder, the carbon content of the finished product is 90%.x0d on average use making pencil graphite electrode, battery, cable lubricant morphological characteristics of a dark metallic luster and opaque fine flake graphite solid. Very soft, creamy sense.

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: Why can graphite powder conduct electricity?: Graphite and diamond, carbon 60, carbon nanotubes are carbon elements, they are allotropes.Laixi, Shandong Province, is one of the important graphite producing areas in China. The proved graphite reserves are 6 million 871 thousand and 100 tons, and the reserves are 6 million 399 thousand and 300 tonsSoft, black, gray, greasy, dirty paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals.

Q: Does graphite allow lubrication of rusted doors?: Sure。 When we were young, the teacher reminded us that we could use the pencil core to scrape the end and put it into the keyhole to lubricate it.

Q: The axis and drum can use graphite powder lubrication: This doesn't seem good. Graphite powder is a solid lubricant. It is suitable for heavy equipment lubrication. The axis and drum or low viscosity lubricating grease is better, so fast.
