The value of high-purity carbon graphite in the industrial industry

Carbon graphite contains carbon graphite with higher purity, which can be called high-purity carbon graphite. Generally, it is widely used in the metallurgical industry, and is involved in the military industry, light industry, and electrical industry, and has excellent chemical and physical properties. There are many kinds of graphite raw materials. According to the molding method of the production era, it can be divided into  molded graphite, and extruded graphite. The finished product will be formed. Therefore, high-purity carbon graphite has high purity and good performance, and has become an important non-metallic mineral raw material in various industrial sectors.

Excellent properties of high purity carbon graphite

1.Thermal stability: Special design is made to ensure the reliability of product quality according to the use conditions of rapid heating and rapid cooling of the product.

2.Erosion resistance: The uniform and fine matrix design delays the erosion degree of the product.

3.Impact resistance: The thermal shock strength that the product can withstand is extremely high, so any process treatment can be carried out with confidence.

4.Acid resistance: The addition of special materials can significantly improve the quality of the product, perform well in acid resistance indicators, and greatly extend the service life of the product.

5.High thermal conductivity: The high content of fixed carbon ensures good thermal conductivity, shortens the dissolution time, and significantly reduces energy consumption.

6.Control of metal pollution: strict control of material composition ensures that the product does not pollute the metal when it is dissolved.

The difference between domestic and foreign carbon graphite processe

(1)Different molding processes: At present, the Franli factory mainly uses cold isostatic pressing, which can compact the graphite powder, make the density distribution of the green compact uniform, and have the advantages of small anisotropy coefficient. Foreign enterprises use hot isostatic pressing, which is a process technology that subject materials to isostatic pressing under the simultaneous action of high temperature and high pressure, which not only improves the compactness of the green compact, but also saves time and improves work efficiency.

(2)  The carbon-graphite calcining process is different: the calcined carbon-graphite equipment used by the Franli factory and many Chinese enterprises is the Acheson graphitization furnace, while the internal-heating series-connected graphitization furnace is mostly used abroad.

(3)Process flow: China’s carbon graphite needs to be calcined and impregnated to achieve production goals, so the domestic process is more complicated.

The main use of high-purity carbon graphite

The characteristics of high-purity graphite include high temperature resistance below 3000C, no deformation at high temperature, high electrical conductivity, friction resistance, self-lubricating, economical, etc.

1. Carbon graphite for electronic semiconductor industry: semiconductor graphite molds, fuel cell guide plates, graphite substrates, graphite pads for cutting silicon rods, graphite linings for electron beam evaporation, graphite boats for glass metal packaging, graphite for electronic sintering molds, ions Graphite parts for injection, graphite thermal fields for single crystal furnaces, etc.

2. Carbon graphite for high temperature treatment of industrial furnaces: used for various heating elements in large industrial furnaces or vacuum furnaces, heating chambers, hearths, heating pipes, brackets, connecting plates, regulating plates, connectors, conductive rod joints, heaters , Insulation room, tray, burning box, graphite plate, etc.

3. Carbon graphite for diamond tool sintering molds: graphite composite molds, clay molds, gauge rings and nozzle rods for oil drills

4. Carbon graphite for machinery industry: carbon graphite sealing dynamic ring, sealing static ring, graphite bearing, lubricating column, carbon graphite blade, mechanical seal parts impregnated with various metals or resins.

The application of high-purity carbon graphite in the downstream of process technology is constantly developing. With the continuous increase of residents’ income, the quality level of carbon and graphite is continuously improved. Manufacturers continue to improve production process technology, product quality has been greatly improved, and demand has continued to grow.

Its application value is also infinitely expanded. In order to make the development of the carbon graphite industry more orderly, the Franli factory provides a high-quality production workshop for the research of high-purity carbon graphite, so as to better develop and produce carbon graphite and ensure the quality of the products.
