I. Introduction.
Electrode paste is an important raw material in the steel, non-ferrous metals and chemical industries, and is mainly used in processes such as electric furnace steelmaking, electrolytic aluminum and copper. As an important intermediate product, medium-temperature coal asphalt plays a key role in the production process of electrode paste. This article will elaborate on the role of medium-temperature coal pitch in the production of electrode paste.
Second, the properties of medium temperature coal asphalt.
Medium-temperature coal pitch is a dark brown to black viscous liquid with high cohesiveness and stability. Its molecular structure is rich in phenolic hydroxyl groups, carboxyl groups and other active groups, which enable it to chemically react with a variety of materials to form stable binders. In addition, medium-temperature coal asphalt also has good electrical insulation properties and corrosion resistance.
3. The role of medium-temperature coal asphalt in the production of electrode paste.
1.Binder: Medium-temperature coal pitch has strong bonding ability, which can bond electrode materials such as carbon materials, graphite, etc. together to form a dense electrode structure. This helps to improve the conductivity and peeling resistance of the electrode.
2.Reinforcing agent: Medium-temperature coal pitch can form chemical bonds with a variety of materials, thereby significantly enhancing the mechanical strength and thermal stability of the electrode. This helps to increase the lifetime and fatigue resistance of the electrodes.
3.Electrical insulating agent: Medium-temperature coal asphalt has excellent electrical insulation properties, which can effectively prevent the corrosion of the electrode by the current. This helps to ensure the electrical performance and stability of the electrode.
4.Corrosion Resistant: Medium-temperature coal pitch is resistant to a wide range of chemicals, thus protecting the electrode from environmental factors. This helps to extend the life of the electrode.
5.Anti-aging agent: The phenolic hydroxyl group, carboxyl group and other active groups in the medium-temperature coal pitch can react with the oxygen in the air to form a stable oxide film to prevent further penetration of oxygen, thereby delaying the aging of the electrode.
IV. Conclusions. Creative Inspiration Center Medium-temperature coal pitch plays an important role in the production of electrode paste, and its excellent bonding, reinforcement, electrical insulation, corrosion resistance and anti-aging properties help to improve the performance and service life of the electrode. With the rapid development of steel, non-ferrous metals and chemical industries, the application prospect of medium-temperature coal asphalt in the production of electrode paste will be broader.
