AI Technical Summary
In the current process of discharging conductive paste, the material comes into contact with air, resulting in uncontrollable moisture content, which affects the viscosity and dispersibility of the paste.
A real-time monitoring device for conductive agent slurry discharge is adopted, which uses nitrogen to replace the air in the packaging barrel and uses a nitrogen content detector to monitor the nitrogen protection environment in real time, ensuring that the material does not come into contact with air during the discharge process.
This effectively prevents materials from absorbing moisture from the air during the discharge process, maintains stable product moisture content, and ensures nitrogen protection of the discharge environment.
