Product Description

Chian golden supplier provide best price of  industry graphite block




Introduction: In a broad sense, all graphite materials obtained through organic carbonization and then graphitized high temperature treatment can be referred to as Artificial Graphite, such as carbon fiber, pyrolytic carbon and foamed graphite. Artificial graphite in the narrow sense usually refers to a solid material with a low impurity content of carbonaceous raw materials as aggregate, coal tar pitch as a binder, through the ingredients, kneading, forming, carbonization and graphitization process of bulk solid material, Such as graphite electrodes, such as isostatic graphite.


Preparation: There are many ways to make artificial graphite. It is common to use high-quality Calcined Petroleum Coke, the main raw material of which is powdered, in which asphalt is added as a binder and a small amount of other excipients is added. After the various raw materials are well blended, they are press-formed, and then treated at a temperature of 2500 to 3000 ° C in a non-oxidizing atmosphere to make them graphitized.



In the metallurgical industry, natural flake graphite can be used to produce refractory materials such as magnesia carbon bricks and aluminum carbon bricks because of its good oxidation resistance. Artificial graphite can be used as a steelmaking electrode, and electrodes made of natural graphite are difficult to use in the more demanding EAFs.


In the mechanical industry, graphite materials are commonly used as wear and lubrication materials. Natural flake graphite lubricity is better, commonly used as lubricant additives. Corrosive medium transport equipment, extensive use of artificial graphite piston rings, seals and bearings, work without the need for lubricating oil. Natural graphite and polymer resin composite materials can also be used in these areas, but wear resistance as artificial graphite.


In the chemical industry, artificial graphite has the characteristics of corrosion resistance, good thermal conductivity and low permeability. In the chemical industry is widely used in the production of heat exchangers, reaction tanks, absorption towers, filters and other equipment. Natural graphite and polymer resin composite materials can also be used in these areas, but the thermal conductivity, corrosion resistance as artificial graphite.
