Process flow of synthetic graphite

Artificial graphite is an important anode material, and its production process mainly includes the following steps: 1. Raw material processing: High-purity natural powdered graphite is used as the raw material; after being crushed and screened, it undergoes preheating to remove impurities. 2. Compounding molding: The pre-treated graphite powder is mixed with materials such as polystyrene resin, and then a green body of the desired shape is produced through methods such as extrusion molding or injection molding. 3. Pre-carbonization treatment: The green body is placed at high temperature for pre-carbonization treatment. The purpose of this step is to pyrolyze the impurities in the resin and allow the graphite crystals in the green body to gradually form, thereby preparing it for subsequent high-temperature carbonization. 4. High-temperature carbonization treatment: The pre-carbonized billet is placed in a high-temperature furnace for high-temperature carbonization treatment. During this process, the graphite structure is further formed and refined, thereby achieving ideal properties. The above is the general manufacturing process for synthetic graphite. For training on pre-carbonization and high-temperature carbonization, it is recommended that you contact relevant training institutions or research organizations to obtain more detailed and professional information. .
