Carbon and graphite products are used in many different industries and applications due to the unique properties they possess. Carbon and graphite are some of the most important materials used in production today, as they are light weight, strong and wear resistant.
Carbon, often referred to as graphite, is a black material that consists of pure carbon in which its molecules are arranged in a regular hexagonal lattice pattern. It has properties of high thermal conductivity and electrical conductivity. Carbon is considered to be the most versatile material in terms of its application, which ranges from battery and brake pad materials, to seals and honing tools. Carbon and graphite materials can also provide good thermal and electrical insulation, resulting in higher quality products.
The process of carbonization is used in the production of different products from carbon and graphite raw materials. This process involves heating the material at high temperatures, usually between 900 and 1700°C. Depending on the type of material being used, the temperatures and time of carbonization can vary greatly.
The carbonization process can be further divided into two processes, namely pyrolysis and graphitization. Pyrolysis is the process of heating carbon or graphite material to temperatures between 900 and 1400°C without air. Since pure carbon is not very strong and brittle, pyrolysis is used to make carbon and graphite materials harder and stronger depending on the temperatures and time.
Graphitization is the process of heating the material at temperatures ranging from 1200 to 1700°C. There is less oxygen present during this process and it involves the rearrangement of the carbon bond into graphite-type bonds. During this process, the material is allowed to cool slowly increasing the strength and reducing porosity.
The final product of these processes is a strong carbon or graphite material which can be used in a variety of industries such as industrial machinery, aerospace and electrical engineering.
The most important factor to consider in carbon and graphite production is the temperature and times of carbonization and graphitization. The correct combination of heating times and temperatures will determine the strength, hardness and porosity of the final product. It is also important to have an experienced and knowledgeable operator to ensure that the right combination of temperatures and times are used in order to achieve the desired properties of the final product.
At the end of the process, the material is cooled and checked for any flaws and defects. If any defect is found, the operator must adjust the temperature and time until the defect is removed. Once the desired qualities are achieved, the material is ready for use or can be made into individual parts, either machined or molded.
Overall, carbon and graphite products are important materials used in production today due to their unique properties and properties. The process of carbonization and graphitization are essential for ensuring the desired properties of the final product and, ultimately, the success of the overall production process.
