The coordinated effect of self-baking electrode paste and adhesive
In industrial fields such as mine heating furnaces and battery manufacturing, self-baking electrode pastes and adhesives, as key materials, each play an indispensable role.Although the two are different in function and application, they have shown a significant coordination effect in actual production, which has jointly improved product performance and production efficiency.This article will delve into the coordination effect of self-baking electrode paste and adhesive from the aspects of the characteristics, mechanism of action and synergistic effects of the two.
1. The characteristics and functions of self-baking electrode paste
Self-baking electrode paste, as a conductive material in a mine heating furnace, is mainly made of semi-graphitized anthracite, residual pole, graphite crushed, calcined petroleum coke and asphalt and other raw materials by mixing, forming, drying, baking and other processes.This electrode paste is coked and sintered by the joule heat generated by the current in the mine heat furnace to form a conductive carbon electrode.It is characterized by low resistivity, high thermal conductivity, good mechanical strength and excellent oxidation resistance, which can ensure the stable operation and efficient production of mineral heat furnaces.
2. The characteristics and application of adhesives
Adhesive is a kind of material with adhesive function, which is widely used in various fields.In battery manufacturing, adhesives are mainly used to bond particles such as active substances and conductive agents together to form a uniform electrode film structure.Common adhesives such as polyvinyl alcohol (PVDF) have the characteristics of strong initial adhesion, good toughness, and long application period.They can not only effectively improve the binding force of the electrode material, but also affect the pore structure and binder distribution of the electrode during the drying process, thereby optimizing the electrochemical properties of the electrode.
3. The coordinated effect of self-baking electrode paste and adhesive
a. Structure and performance optimization
In the electrode preparation process, self-baking electrode paste and adhesive work together to form and cure the electrode material.Through its good adhesion properties, the adhesive tightly binds the active substance, conductive agent and other particles together to form a stable electrode structure.The self-baking electrode paste provides electrical conductivity and mechanical support in this process, ensuring that the electrode maintains stable operation in the high temperature environment of the mine heat furnace.The coordinated effect of the two makes the electrode structure tighter and more uniform, thereby improving the electrochemical performance and service life of the electrode.
b. Synergistic effects in the drying process
During the drying process of the electrode, the solvent gradually evaporates, and the adhesive precipitates on the surface of the active substance and the conductive agent to form a stable membrane structure.In this process, the thermal conductivity of the self-baking electrode paste helps to accelerate the drying process, while its oxidation resistance can protect the electrode material from high temperature oxidation damage.The adhesive ensures the integrity and stability of the electrode membrane structure through its unique adhesion properties.The synergistic effect of the two enables the electrode to maintain excellent performance and structural stability after drying.
c. Improve production efficiency and reduce costs
The coordinated effect of self-baking electrode paste and adhesive not only improves the performance and quality of the electrode, but also helps to improve production efficiency and reduce costs.By optimizing the electrode preparation process and material ratio, the energy consumption and material consumption in the production process can be reduced, and the yield and service life of the electrode can be improved.At the same time, good electrode performance can also reduce the operating and maintenance costs of mine heating furnaces, and bring significant economic benefits to enterprises.
4. Conclusion
In summary, self-baking electrode pastes and adhesives have shown a significant coordinated effect in the electrode preparation and production process.Through their unique properties and functions, the two jointly improve the performance and stability of the electrode, promote the improvement of production efficiency and reduce costs.In the future, with the continuous progress of technology and the continuous expansion of applications, the coordinated role of self-baking electrode pastes and adhesives will be more in-depth research and application, injecting new impetus into the development of the industrial field.
