Coal asphalt manufacturer Shen Huanhuan.
Coal pitch is a by-product of coal tar processing, which is mainly composed of polycyclic aromatic hydrocarbons and hydrocarbons. Due to its unique chemical composition and properties, coal pitch has a wide range of applications in many fields. Among them, medium-temperature asphalt plays an important role in the production of graphite electrodes.
In the production of graphite electrodes, medium-temperature bitumen is widely used as a binder and impregnation agent. Since the manufacture of graphite electrodes requires high temperature treatment, the binder is required to have high thermal stability. Due to its high aromatic and chemical stability, medium-temperature asphalt can maintain good bonding properties at high temperatures, thereby improving the mechanical strength and conductivity of graphite electrodes.
In addition, medium-temperature asphalt also has good impregnation properties, which can evenly impregnate graphite particles, making it less prone to cracking and spalling at high temperatures. At the same time, medium-temperature asphalt can also fill the voids between graphite particles during the impregnation process, reduce the retention of gas inside the electrode, and thus improve the conductivity and corrosion resistance of the electrode.
Medium-temperature bitumen also has some other advantages in the application of graphite electrodes. For example, it can be processed and handled at lower temperatures, reducing energy consumption and pollution to the environment. In addition, the ** of medium-temperature asphalt is relatively low, which can reduce the production cost of graphite electrodes.
Overall, medium-temperature bitumen plays an important role in the production of graphite electrodes. It not only improves the mechanical strength and conductivity of graphite electrodes, but also has lower temperature processing and handling requirements and relatively low **. With the increasing demand for graphite electrodes, the application prospects of medium-temperature asphalt will also be broader.
