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.

Q:Where are the graphite powders sold?
From graphite powder production, packaging, sale, delivery one-stop service, eliminating the agent and intermediary price differentials, and direct profits to customers.
Q:Why is there a range of electrode powder powder resistivity? The reasons for the high and low are not good.
Powder resistivity tester, the sample broken to 0.3 ~ 0.5mm, into the powder resistivity instrument insulation sleeve, the tube diameter of 16.3mm, in the bushing into the sample.
Q:What is the simple test method for graphite powder used in casting?
Mainly depends on its carbon content, hand stick a little bit on the white paper uniform, if there is a clear scratch is graphite powder
Q:What is graphite powder?
Graphite is a crystalline mineral of carbonaceous elements. Its crystalline framework is hexagonal layered structure. The distance between each network layer is 340pm, and the distance between the carbon atoms in the same network layer is 142pm;. Of the six Fang system with a complete lamellar cleavage. The cleavage surface is mainly based on molecular bonds, and has weaker molecular attraction, so its natural floatability is very good.Graphite and diamond, carbon 60, carbon nanotubes are carbon elements, they are allotropes.
Q:What does composite graphite mean?
Flexible graphite is prepared into graphite powder as a kind of simple, while the composite graphite is graphite powder with one or more other medium mixed products, their preparation materials are different, the application is different, the above information is a reference to Qingdao Huatai graphite.
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 made of graphite oxide, how much weight gain?
The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5.
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:What is the use of flake graphite in making flake graphite powder?
Flake graphite is widely used in advanced refractory materials and coatings of metallurgical industry. Such as bricks, crucible etc.. Military industrial explosive materials stabilizer, smelting industrial desulfurization growth agent, light industry, electrical industry pencil brush, industrial battery electrode and catalyst in chemical fertilizer industry, etc.. Flake graphite is further processed and can be used to produce graphite milk. It is used as lubricant, release agent, drawing agent and conductive paint. Expandable graphite can also be used for flexible graphite products, such as flexible graphite seals and flexible graphite composite products.
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.
