Industrial Minerals
The chemical properties of graphite are very stable, high temperature resistance, corrosion resistance, and good conductivity.Therefore, graphite can be used as refractory material, sealing material, conductive material, and is widely used in high temperature metallurgy, sand finding, paint lubricant, pencil lead, pigment, polishing agent, petrochemical industry, synthetic fiber, heater and other industries.
Natural graphite
The graphite electrode comprises: (1) Regular power graphite electrode( RP grade Graphite Electrode) . Graphite electrode with current density less than 17a / cm2 is allowed to be used in common power electric furnaces for steelmaking, silicon smelting and yellow phosphorus smelting. (2) Oxidation resistant coating graphite electrode. A graphite electrode coated with an anti-oxidation protective layer (graphite electrode anti oxidant). The formation of both conductive and high temperature oxidation resistant protective layer can reduce the electrode consumption (19% ~ 50%), prolong the service life of the electrode (22% ~ 60%), and reduce the electric energy consumption of the electrode. The popularization and application of this technology can bring such economic and social effects as follows: 1. The unit consumption of graphite electrode is less, and the production cost is reduced to a certain extent. For example, according to the consumption of 35 graphite electrodes per week and 165 refining heats of LF refining furnace in a steel-making plant without shutdown in the whole year, 373 (153 tons) electrodes can be saved every year by using graphite electrode oxidation resistance technology, and RMB 2585700 can be saved by RMB 16900 per ton of ultra-high power electrode per year. 2 The graphite electrode consumes less electricity, saves the unit electricity consumption of steelmaking, saves the production cost, saves energy! 3. Because the graphite electrode is replaced less times, the labor amount and risk coefficient of operators are reduced, and the production efficiency is improved. 4 Graphite electrode is a high consumption and high pollution product, which has a very important social significance in the days of promoting energy conservation, emission reduction and environmental protection. This technology is still in the stage of research and development in China, and some domestic manufacturers have begun to produce it. It is widely used in Japan and other developed countries. At present, there are also companies that import the anti-oxidation protective coating in China. (3) High power graphite electrode (HP grade Graphite Electrode). Graphite electrode with current density of 18-25a / cm2 is allowed to be used in high power electric arc furnace for steelmaking. (4) Ultra high power graphite electrode( UHP grade Graphite Electrode). Graphite electrode with current density greater than 25A / cm2 is allowed. It is mainly used in ultra high power EAF.
Graphite Paper, Sheet plate Description : Graphite paper and graphite plate: it is made of high carbon phosphorus graphite by chemical treatment and high temperature expansion rolling. It is the basic material for manufacturing various graphite seals. It is widely used in the dynamic and static seals of machines, pipes, pumps and valves in electric power, petroleum, chemical industry, instrument, machinery, diamond and other industries. It is an ideal new sealing material to replace traditional seals such as rubber, fluoroplastic and asbestos. With the acceleration of the upgrading of electronic products and the increasing demand for heat dissipation management of mini, high integration and high-performance electronic equipment, a new heat dissipation technology of electronic products, that is, a new heat dissipation solution of graphite material, has also been introduced. This new natural graphite solution uses graphite paper with high heat dissipation efficiency, small occupied space and light weight. It conducts heat evenly in both directions, eliminates "hot spot" areas, shields heat sources and components, and improves the performance of consumer electronic products.

Graphite paper is divided into l Flexible graphite paper l Ultra-thin graphite paper l Sealed graphite paper l Heat conductive graphite paper l Conductive graphite paper, etc. different kinds of graphite paper can play their due role in different industrial fields. The following two items shall be paid attention to when storing graphite paper: 1. Storage environment: graphite paper is suitable to be placed in a dry and flat place, and is not exposed to the sun to prevent extrusion and reduce collision in the production process; It has certain conductivity, so when it needs to be stored, it should be far away from the power wire. 2. Prevention of cracking: the graphite paper is very soft, and we can cut it according to requirements. In order not to break them during storage, it is not suitable for folding or bending and folding at a small angle. General graphite paper products are suitable for cutting into sheets, such as rolled into barrels or flat storage in the shape of A4 paper.
