2023-09-18Graphite is an important mineral resource in the 21st century, and China ranks first in the world in terms of graphite ore reserves. With the improvement of graphite product processing technology, it has been widely used in fields such as chemical engineering, smelting, casting, new materials, molds, aerospace, etc. We often see many chemical properties of graphite products in the industry, such as graphite crucibles, graphite heaters, graphite molds, etc(1) High temperature resistance: In smelting, the melting point of graphite products is 3850 ± 50 ℃, and the boiling point is 4250 ℃. Even after being ignited by an ultra-high temperature arc, the weight loss and thermal expansion coefficient are very small. The strength of graphite increases with temperature, and at 2000 ℃, the strength of graphite doubles.(2) Good conductivity and thermal conductivity: The conductivity of graphite products is 100 times higher than that of ordinary non-metallic minerals. The thermal conductivity exce
2023-09-21In the graphite industry, it is well known that graphite products are widely used in many industries. It is believed that friends who often walk in graphite rings know about graphite sealing rings. So why is graphite used as a sealing material? This is a question worth exploring.Graphite has characteristics that cannot be replaced by other metal materials, such as conductivity, good thermal conductivity, and excellent corrosion resistance. Choosing it as a sealing material also has its own special characteristics. Carbon graphite rings have physical and mechanical properties such as high temperature resistance, self-lubrication, low friction coefficient, wear resistance, and low thermal expansion coefficient. Therefore, graphite sealing rings can be seen in various industrial sectors such as papermaking, textile, and medicine.Moreover, graphite blocks can not only be used as graphite sealing rings, but also as various types of graphite machined parts in other industries.
2023-09-21The first aspect is the flexural strength of the material. The flexural strength of a material is a direct reflection of its strength, indicating the tightness of its internal structure. Materials with high strength have relatively good resistance to loss during discharge. For electrodes with high precision requirements, it is recommended to choose materials with better strength.The second aspect is the Shaw hardness of materials. In the subconscious understanding of graphite, it is generally considered a relatively soft material. But actual test data and application situations show that the hardness of graphite is higher than that of metal materials. In the special graphite industry, the commonly used hardness inspection standard is the Shore hardness measurement methodThe third aspect is the average particle diameter of the material. The smaller the average particle size of the material, the more uniform the discharge of the material, the more stable the discharge condition, and the
2023-09-20Graphite sells various models and specifications of graphite rods, graphite columns, graphite particles, graphite powder, graphite bearings, and graphite tubes, including lubrication, high purity, conductivity, and wear resistance. We can process various shapes of graphite products according to customer requirements.Graphite products have been widely used in industrial machinery due to their wear resistance and lubrication effects. In actual industrial production processes, the oxidation resistance of graphite products has always been a concern of the graphite industry. So what is the relationship between the oxidation resistance of graphite products?It can be seen that the self-lubrication of graphite depends on the presence of air and water. As a lubricating material, the critical value of moisture in the working environment of graphite products is 5g/m3. If it falls below this value, the friction coefficient of graphite products will increase. At room temperature of 300-400 degrees
2023-09-20In recent years, with the development of graphite processing technology, graphite parts have played an important role in various industries.According to the needs of different industries, graphite materials are made into different graphite parts. In order to improve the performance of graphite parts, special treatment is carried out on them. Graphite components play important roles in a wide range of fields, including sealing, temperature resistance, corrosion resistance, conductivity, insulation, compression resistance, wear resistance, and oxidation resistance.Widely used in advanced refractory materials and coatings in the metallurgical industry, carbon brushes in the electrical industry, electrodes in the battery industry, and catalyst additives in the fertilizer industry. After deep processing, high-purity graphite can also produce high-tech products such as graphite sealing materials and composite materials, graphite products, and graphite wear reducing additives, becoming an im
2023-09-19Graphite machined parts are widely used in industry due to the excellent characteristics of artificial graphite materials that cannot be replaced by other metal materials.Graphite machined parts have good conductivity, and with the development of the industry, the size of graphite sheets also changes. In addition, graphite machined parts can also be used as lubricating rings in the electromechanical manufacturing industry as conductive materials.Due to the integration of high-temperature and corrosion resistance of graphite materials into graphite machined parts, many metallurgical furnace linings are made of graphite materials. However, graphite machined parts used as refractory materials must undergo good oxidation resistance treatment when used in oxidizing degassing.Graphite machined parts can be used as corrosion-resistant structural materials. All graphite machined parts need to be impregnated with organic resin to achieve optimal corrosion resistance. Most of them are used as b
