Artificial Graphite for sales

Artificial graphite is analogous to polycrystals in crystallography. There are many kinds of artificial graphite and different production techniques. In a broad sense, all the graphite materials obtained by organic carbonization and graphitization high-temperature treatment can be collectively referred to as artificial graphite, such as carbon (graphite) fiber, pyrolytic carbon (graphite), graphite foam, etc…In a narrow sense, artificial graphite usually refers to the carbon raw materials with low impurities content (petroleum coke, asphalt coke, etc.) as aggregate, coal asphalt, and other binders, after batching, mixing kneading, molding, carbonization (known as roasting in the industry) and the graphitization and other processes made massive solid materials, such as graphite electrode, isostatic pressing graphite.

The shape of artificial graphite is more, both powder, fiber, and block, and the narrow sense of artificial graphite usually block, when used, it needs to be processed into a certain shape. It can be regarded as a kind of multiphase material, including graphite phase transformed by carbonaceous particles such as petroleum coke or pitch coke, graphite phase transformed by coal pitch binder coated around the particles, pore formed by particle accumulation or coal pitch binder after heat treatment, etc. Generally speaking, the higher the heat treatment temperature, the higher the graphitization degree. The degree of graphitization of artificial graphite produced by industry is usually less than 90%.

The artificial graphite produced by Franli has the advantages of better wear resistance, corrosion resistance, and low permeability than natural graphite and has good characteristics.

Artificial graphite product application is mainly reflected in the following aspects:

1. Graphite electrode: with petroleum coke, needle coke as raw material, coal pitch as binder, calcination, ingredients, kneading, molding, baking and graphitization, machining, made of graphite electrode, in electric arc furnace in the form of arc release of electrical energy to heating melting furnace charge in the electric furnace steel, industrial silicon, such as widely used in the system.

2. Pre-baking anode: it is made of petroleum coke as raw material and coal asphalt as a binder by calcination, batching, mixing, pressing, roasting, impregnation, graphitization, and machining. It is generally used as a conductive anode of electrolytic aluminum equipment.

3. Bearings and closed rings: equipment for conveying corrosive media, piston rings, sealing rings, and bearings made of artificial graphite are widely used, without adding lubricating oil when working.

4. Heat exchanger, filtration: artificial graphite has the characteristics of corrosion resistance, good thermal conductivity, low permeability. It is widely used in the chemical industry to make heat exchangers, reaction tanks, absorbers, filters, and other equipment.

5. Special graphite: by the high-quality petroleum coke as raw material, coal tar or synthetic resin as binder, the raw material preparation, the ingredients, kneading, pressing, grinding and kneading, molding, roasting, multiple invasion stains, purification and graphitization, machining, generally including isostatic pressing nuclear graphite, high purity graphite, graphite, etc., used in aerospace, electronics, nuclear industry sector.

Franli has different specifications of artificial graphite, can provide to meet different needs of artificial graphite, good quality and appropriate price, welcome to buy.
