In the past 50 years, isostatic pressing graphite has rapidly emerged as a new type of material internationally, closely related to today's high-tech and highly anticipated. It plays an important role in both civil and national defense fields, and is widely used in the manufacturing of irreplaceable materials such as single crystal furnaces, metal continuous casting graphite crystallizers, and graphite electrodes for electrical discharge machining. This article will delve into the preparation methods, properties, and important applications of isostatic pressing graphite in various fields.
Preparation Method of Isostatic Pressing Graphite
The forming methods of graphite products mainly include hot extrusion forming, mold pressing forming, and isostatic pressing forming. In the production method of isostatic pressing graphite, the raw material is subjected to all-round pressure, and the carbon particles are always in a disordered state, resulting in almost no or very little performance difference in the products. The directional performance ratio is not greater than 1.1. This characteristic makes isostatic pressing graphite known as "isotropic".
Widely applied fields of isostatic pressing graphite
The application fields of isostatic pressing graphite are very extensive, including two main aspects: civil and national defense:
In the civil field, the application of isostatic pressing graphite is widely diverse. It can be used to manufacture single crystal furnaces, which play a crucial role in high-tech fields such as electronics and aerospace, helping to produce high-quality single crystal materials. In addition, in the field of metal continuous casting graphite crystallizers, isostatic pressing graphite can improve the crystallization quality of the metal and be used to prepare high-quality casting products. At the same time, in electric discharge machining, the isostatic pressing graphite electrode has high conductivity and thermal stability, helping to achieve high-precision electric discharge machining.
In the field of national defense, isostatic pressing graphite also occupies an important position. It can be used to manufacture graphite components in aviation engines, improving engine performance and durability. In missile guidance systems, isostatic graphite can be used to manufacture high-precision stabilizers and attitude controllers, improving the accuracy of missiles. In ship construction, isostatic graphite can also be used to manufacture ship propellers and rudder blades, improving the performance and handling ability of naval vessels.
Overall, isostatic pressing graphite is a new type of material closely related to high-tech and has important applications in both civil and national defense fields. Its widespread and irreplaceable characteristics have made isostatic pressing graphite a popular product. However, the domestic isostatic pressing graphite production process still needs improvement to enhance product quality and competitiveness. Domestic manufacturers should actively learn from advanced foreign experience, strengthen technological research and development, and optimize production processes to promote the development of China's isostatic pressing graphite industry, in order to meet the growing market demand.
