What is amorphous graphite?

Graphite powder is a kind of mineral powder. The main component is carbon single quality, and the quality is soft, black, and gray; have a greasy feeling, and can pollute the paper. The hardness is 1 to 2, a nd the hardness can increase to 3 to 5 along the vertical direction. The specific gravity is 1.9~2.3.

The amorphous graphite texture is soft under the condition of oxygen isolation conditions, its melting point is more than 3000℃, and one of the high-temperature resistant minerals. At room temperature, amorphous graphite is stable, insoluble in water, dilute acid and dilute alkali. When oxygen is sufficient, oxygen reacts with oxygen to produce carbon dioxide; fluorine energy directly reacts with elemental carbon; at high temperature, it can reduce many metals, such as iron making.

Graphite powder is a very sensitive chemical reaction material. In different environments, its resistance will change. The resistance value will change, but one thing will not change. Graphite powder is a very good non-metallic conductive material as long as in the insulating object, to ensure that the amorphous graphite is uninterrupted, like a fine line will be charged. However, the value has no accurate value. Due to the different thicknesses of amorphous graphite, the resistance of amorphous graphite is also different in different materials and environments.

The specifications of fine amorphous graphite are 100,200,325,800,1200,2000,4000,5000,8000,10000,12,000,12500, l5000 items, anticorrosion coating models, rubber special, special lubricating oil special, glass steel special, ink special, dry battery special, alkaline battery special, lubricating coating, powder metallurgy special, special graphite milk, etc.

Graphite powder process

Graphite has many excellent properties, such as electrical conductivity, thermal conductivity function, and complete product detection means, in addition to the vacuum, the impurity content should not exceed dozens of (one in a million). The constant pressure skill can make use of small-scale graphite, in the clay graphite crucible, the whole process is carried out on special equipment equipped with a roller. The graphite mold has a complex shape and an uneven thickness. In the process of amorphous graphite, about 3 / 4 of the scale graphite of the carbon content reaches the standard. The anode of the electrolytic cell also uses a graphite electrode, which pads soft material under the end of the spare electrode joint to prevent the ground from damaging the joint. With the hook extended into the lifting ring of the hanger, the backup electrode of the amorphous graphite process, the testing facilities are complete and check whether the thread in the electrode hole is complete. In addition to the characteristics of natural graphite, this product also has the excellent properties of artificial graphite.

Graphite powder is mainly used in powder metallurgy, lubricating oil, grease, dry battery, conductive coating, lubricating coating, national Defense committee of Science and Industry, scientific research institutions of scientific research, civil electricity, aerospace, and strategic power interference weapons, smoke screen shielding weapons, etc. The different processes of amorphous graphite will change the price of amorphous graphite. Different properties of amorphous graphite will make the application of amorphous graphite different. Generally, amorphous graphite is ground through the air flow. Purity of amorphous graphite purity (carbon content) includes carbon content (FC), volatile content (VC), ash (ASH), etc. According to the size of the broken material or broken material, the grinder can be divided into coarse crusher, medium crusher, fine mill, and ultra-fine mill. In the process of crushing the graphite blocks applied to the solid, the synthetic graphite blocks are mainly after pressing, roasting, graphitization products, and processed powder. The natural amorphous graphite is added through the right amount of natural amorphous graphite to add the right amount of resin into the model compaction, after the resin curing, open the model of the amorphous graphite you need will come out. How can we turn the amorphous graphite into a graphite block? What processing equipment is required? First of all, you want to put the amorphous graphite broken to a certain number, and then add oil coke, namely, we often say drain glue, but imported oil coke than domestic oil coke effect, amorphous graphite after adding oil coke, into thousands of tons of hydraulic press to suppress, after in thousands of degrees of high temperature for roasting 3-6 months, after amorphous graphite into graphite block.

Application of amorphous graphite

Used in refractory materials: graphite and its products have the properties of high-temperature resistance, and high strength. In the metallurgical industry is mainly used to manufacture graphite crucibles, in steelmaking commonly used graphite as the protective agent of steel ingot, metallurgical furnace lining.

For conductive materials: used in the electrical industry as the manufacture of electrodes, brushes, carbon rods, carbon tubes, graphite washers, telephone parts, TV imaging tube coating, etc.

For lubricating materials: graphite is often used as a lubricant in the mechanical industry. Lubricating oil often can not be used in high speed, high temperature, or high-pressure conditions, while graphite lubrication materials can work at a temperature of 2000℃ without lubricating oil.

For high-temperature metallurgy materials: graphite has a reduction property, at a high temperature can use reduction property to reduce many metal oxides, and can be smelting metals, such as iron making.

Used for abrasive agent and rust prevention agent: graphite is also the abrasive agent and rust prevention agent for glass and paper making in the light industry, and it is an indispensable raw material for making a pencil, ink, black paint, ink, and artificial diamond and diamonds.

Graphite powder is a very valuable graphite product, which has a wide range of applications in many high-end fields. Many university laboratories have bought amorphous graphite from Luoyang Yuexing for scientific research. Because of the advanced grinding equipment, the amorphous graphite of Luoyang Yuexing is very fine and can reach the nano level, called nano amorphous graphite, or nano-level amorphous graphite. The performance is particularly excellent and can be used as an additive to change the product performance.
