Introduction to the main solid carbon raw materials of electrode paste

Introduction to the main solid carbon raw materials of electrode paste Carbon material is a kind of granular structured material, which is made from various kinds of raw materials with different particle sizes by adding a binder, kneading, forming, roasting and graphitizing. Therefore, the performance of the material is not only related to the particle size, the type and amount of binder, and the process control and operation in the production process, but also has an important relationship with the type and performance of the raw material itself. There are many solid raw materials used in the production of carbon materials, such as ordinary petroleum coke, needle-shaped petroleum coke, pitch coke, artificial graphite, natural graphite, carbon black, anthracite, metallurgical coke, charcoal, sugar charcoal, bone charcoal, etc.; for electricity Carbon products, as well as copper, silver, tin, lead and other metal powders and artificial resins; for mechanical carbon and furnace lining materials, there are silicon carbide, silicon dioxide, clay clay, etc.; for carbon fiber and its composite materials, there are also artificial resins. Silk, polypropylene, etc.

Natural carbon-containing minerals and various man-made carbon raw materials, although essentially composed of carbon elements, have different physical and chemical properties. The reason is mainly due to their different production conditions, so the arrangement of carbon atoms and the bond between carbon atoms are different. Some are crystalline structures, such as graphite and diamond; some are amorphous structures, such as petroleum coke, pitch coke, anthracite, metallurgical coke, etc. It is also related to the properties and structure of the carbon-containing minerals that produce these carbon raw materials. For example, the properties of petroleum coke, metallurgical coke, and anthracite are different. Even for similar minerals, the properties of carbon raw materials produced from different places of production are not exactly the same. For example, the properties of Daqing petroleum coke and Shengli petroleum coke are different. Therefore, in the production of carbon materials, we must first conduct in-depth and systematic research and understanding of different types of raw materials, and then study their influence on the performance of carbon materials, and then select and cooperate according to the product performance requirements in order to find out their regularity. And then used to guide production.

At present, although many achievements have been made in the research of carbon materials, it is still impossible to make precise calculations and accurate descriptions in terms of microstructure, even deeper chemical bond structure, electronic structure and energy band theory. With the nature of experience. Based on the experience gained from long-term production practice, people have summarized the scope of application of various main raw materials, and made certain theoretical explanations on the macro level, and the characteristics and application scope of various main carbon raw materials.
