Graphite products are a type of material widely used in industrial and daily life fields, and their production process and working principle involve graphite powder preparation, graphite material forming, and graphite product processing. The following will provide a detailed introduction to the production process and working principle of graphite products, and explore their applications in different fields.

The production process of graphite products includes multiple steps such as raw material preparation, mixing, molding, high-temperature sintering, and processing. Firstly, the preparation of graphite powder is one of the key steps in producing graphite products. Generally, a crusher is used to crush graphite ore or natural graphite into appropriate particle sizes. Then, the graphite powder is mixed to adjust its chemical composition and physical properties to meet specific application requirements. Mixing can be done through dry or wet methods, usually using a mixer or ball mill.

The next step is the molding process. After mixing the graphite powder, it needs to be molded to form the desired shape of the graphite product. Common molding methods include extrusion molding, injection molding, die-casting molding, and impregnation molding. Among them, extrusion molding is one of the most commonly used methods. In extrusion molding, the mixed graphite powder is placed into a mold and subjected to external pressure to form the desired shape in the mold. Injection molding is the process of molding using melted graphite powder. The melted graphite powder is injected into a mold using an injection molding machine, and then cooled and solidified to obtain the desired shape of the graphite product.

After forming, high-temperature sintering treatment is also required. Sintering is the high-temperature treatment of formed graphite products to make their structure compact, improve their mechanical and heat resistance properties. The sintering temperature and time will be adjusted according to the requirements of different graphite products. In general, the sintering temperature of graphite products is relatively high, usually above 2000 ℃. Graphite materials undergo crystal rearrangement and bonding at high temperatures, resulting in graphite products having high strength and hardness.

Finally, proceed with the processing of graphite products. After sintering, graphite products still need to undergo final processing to achieve the required details and precision requirements. The processing of graphite products includes cutting, drilling, grinding, and grinding. These processing steps can be selected based on the characteristics and application requirements of the product.

The working principle, characteristics, and applications of graphite products are closely related. Firstly, graphite products have excellent electrical and thermal conductivity. Graphite is a carbon material with a layered structure, where the bonding between layers is weak, resulting in graphite products having good conductivity. Therefore, in the fields of electronic components and electromagnetic shielding, graphite materials are commonly used to make conductive plates and sheets. In addition, the high thermal conductivity of graphite products makes it an ideal material for making graphite molds and graphite electrodes.

Secondly, graphite products have good chemical stability and corrosion resistance. Graphite is an inert material that is not prone to chemical reactions with most chemicals. Therefore, graphite products are widely used in the chemical industry for manufacturing acid-base tanks, reactors, pipelines, etc., and can also be used to manufacture corrosion-resistant equipment such as acid-base pumps and dosing pumps.

In addition, graphite products also have good thermal expansion and high temperature resistance. Graphite material expands less at high temperatures and has excellent heat resistance
