Product Description:

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.
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:Why does the temperature rise when the graphite powder is turned on?
The presence of resistance, melting point at 3850 + 50 degrees C, graphite powder is a very sensitive chemical substances, in different circumstances, his resistivity will change, that is, his resistance value will change
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: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?
If it is a long-term work in the environment first, graphite dust masks, the more than 2 eat bananas, like blood. Case said harmful, you can not see any problems with graphite processing. In short, the dust class should pay attention to, and avoid direct inhalation
Q:Whether the lubricating oil toner is coupled with the conductor?
Not really. It depends on the amount of graphite powder. If the graphite powder forms a continuous through zone, it can be considered a conductorYou can use lubricating oil, preferably not with graphite, which will cause the sliding rheostat to fail
Q:For thermal grease skills, the more detailed the better
But this is not possible, the metal lid heat sink and CPU looks smooth, but with a magnifying glass, you can see many holes in metal surface concave stripes and irregular tunnel, lead contact surface with many gaps, these gaps are impeding heat dissipation, thermal grease is liquid, can fill the gaps. Improved radiating surface contact, the heat dissipating effect than when there is no good thermal grease. But if the thermal grease is too thick, it will become a film on the contact surface of the middle, but hindered the direct contact of metal, worse than not coated with thermal grease.
Q:Why should the lubrication of automobile leaf springs be made of graphite grease?
Graphite grease is a kind of graphite grease made from inorganic thickener, condensed ester, synthetic oil, and refined with superfine graphite powder, no oxidation, corrosion resistance and other additives.
Q:The graphite powder production process and the graphite production process are introduced briefly Graphite powder production process, graphite production process, detailed technical parameters where?
According to the size of the crushed or broken material, the mill can be divided into coarse crusher, middle crusher, fine mill and superfine mill.
Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.
Dust explosion condition(1) flammable dusts are suspended in the air at proper concentration to form dust clouds which are often called;(2) adequate air and oxidizing agents;(3) there is fire or strong vibration and friction. Generally believed that the explosive dust as long as the conditions (1) and conditions (2), it means that there are possible signs of the accident.
Q:Why does an electromagnetic point timer not prick a needle and use toner paper?
With the needle point than the powder paper friction, many experimental results of!
Q:Does graphite allow lubrication of rusted doors?
Tolerable。 However, there is a premise: rust must be removed with rust.Lock force rust is generally not easy to lock inside the material easily rust off, then need to use oil to rust, rust removing, the graphite powder filling hole, and then the key to rotate back and forth, you can make the door lubrication.
