Graphite, as a mineral material with unique physical and chemical properties, plays an irreplaceable role in many industrial fields due to its high temperature stability, good electrical and thermal conductivity, and easy processing and molding. Graphite product processing, as an important link in graphite application, not only involves complex processes and technologies, but is also directly related to the performance and quality of graphite products. This article will conduct an in-depth exploration of graphite product processing, covering its processing methods, technical requirements, and application fields.1. Graphite product processing methodsThe processing of graphite products usually includes raw material pretreatment, molding, processing and post-processing.Raw material pretreatment: High-quality natural graphite or artificial graphite powder is the basis for graphite product processing. These raw materials need to be pretreated through screening, mixing and other steps to ensure that their particle size is uniform and the composition is stable, laying a good foundation for subsequent processing.Molding: The pretreated graphite powder is mixed with an organic binder and a hardener to form graphite flakes, which are then molded into the desired shape and size by pressing, molding or injection molding. This link requires extremely high control of molding pressure and temperature to ensure the density and strength of graphite products.Processing: Graphite products after molding often need further processing, such as machining, drilling, grinding, etc., to obtain the required model, size and shape. During the processing, special attention should be paid to avoid overheating, overgrinding and other operations to maintain the characteristics of graphite.Post-processing: After processing, graphite products may also need post-processing steps such as cleaning, drying, coating, etc. to improve their surface finish, wear resistance and corrosion resistance.2. Technical requirements for graphite product processingGraphite product processing has high technical requirements, which are mainly reflected in the following aspects:Precision control: The processing accuracy of graphite products is often required to be high, especially in the fields of electronics, semiconductors, etc., and small dimensional deviations may lead to product performance degradation. Therefore, high-precision equipment and processes are needed in the processing process to ensure the dimensional accuracy and shape accuracy of the product.Surface finish: The surface finish of graphite products has an important influence on its performance and application effect. Especially in the field of EDM, high surface finish can reduce the discharge gap and improve processing efficiency and quality.Wear resistance: Graphite products are easy to wear during processing and use, so they need to have high wear resistance. This requires the use of appropriate processes and materials during processing to improve the wear resistance of the product.Conductive performance: As a good conductor, graphite has an important influence on the application effect of the product. During the processing, it is necessary to ensure that the conductive performance of the product is not damaged to meet the application requirements of specific fields.3. Application fields of graphite productsGraphite products are widely used in various fields due to their unique properties, mainly including:Electronic field: Graphite products are widely used in the electronic field, such as graphite electrodes, graphite molds, etc. These products play an important role in electronic packaging, semiconductor manufacturing and other fields due to their good conductivity and high temperature stability.Metallurgical field: The application of graphite products in the metallurgical field is mainly concentrated in industrial processes such as steelmaking and aluminum smelting. As an important component of electric furnace steelmaking, graphite electrodes can withstand the impact of high-temperature arcs without deformation, which greatly improves steelmaking efficiency and product quality.Chemical industry: The application of graphite products in the chemical industry is mainly reflected in corrosion-resistant equipment and heat exchangers. Graphite materials have good corrosion resistance and thermal conductivity, which can effectively improve the service life and efficiency of chemical equipment.New energy field: With the rapid development of the new energy industry, the application of graphite products in lithium-ion batteries, fuel cells and other fields is becoming more and more extensive. Graphite negative electrode materials have become an important part of lithium-ion batteries due to their high specific capacity and long cycle life.Graphite product processing is a field involving complex processes and technologies, and its product quality and performance are directly related to the effects and benefits of the application field. With the advancement of science and technology and the development of industry, graphite product processing technology will continue to innovate and improve, providing better quality graphite products for more fields. At the same time, we also look forward to graphite products showing their unique charm and value in applications in more fields.
