What are the commonly used plasticizers and lubricants in electrode paste?
In the preparation process of electrode paste, plasticizers and lubricants are two very important additives. They are used to adjust the plasticity and flowability of the electrode paste, which in turn affects its processing performance and the quality of the final product. The following are some commonly used plasticizers and lubricants:
Plasticizers:
Petroleum-based plasticizers, such as cyclohexane oil and aromatic oil, are commonly used in electrode paste to enhance its plasticity and flowability.
Mineral oil: Mineral oil can also serve as a plasticizer, reducing the paste's viscosity and improving its ductility and plasticity.
Lubricants:
Mineral oils and fats, such as paraffin and microcrystalline wax, can be used as lubricants to reduce the frictional resistance of electrode paste during the forming process.
Synthetic lubricants, such as polyether and silicone oil, are stable at high temperatures and suitable for special electrode paste processing requirements.
Natural oils and fats, such as vegetable oil and animal fat, can be used as natural lubricants, though they are less commonly used in industrial production.
It is important to note that the type and amount of plasticizers and lubricants should be carefully selected based on the specific formula and desired performance of the electrode paste. Excess or insufficient plasticizers and lubricants can adversely affect the performance of the electrode paste. Therefore, production and formulation engineers must conduct extensive experiments and testing to determine the optimal type and ratio.
