Aluminum-plastic film is a special packaging material for lithium-ion batteries, often used in pouch batteries and blade batteries. It mainly plays the role of protecting the internal electrodes and isolating the external environment. The film coating machine can be applied to the coating of aluminum-plastic film.
Membrane method
The following is a possible method of film production:
Prepare the coating solution, select appropriate organic solvents, polymers and other additives as needed, and mix and stir them evenly.
Place the aluminum plastic film under the coating head, and pour the coating solution into the coating head.
Set the movement speed and coating pressure of the coating head according to the desired film thickness and speed.
Start the Film Applicator and start coating.
After coating, place the coated aluminum-plastic film in a drying room to dry.
For some aluminum-plastic films that require special treatment, such as anti-static, anti-oxidation, etc., corresponding post-treatment processes are also required.
NBCHAO reminds you: when coating aluminum-plastic film, it is necessary to ensure the cleanliness and flatness of the surface of the coating head and coating plate to ensure the uniformity and quality of the film. In addition, it is also necessary to set reasonable coating parameters according to the characteristics and requirements of the coating materials used to obtain better coating effects. After the coating is finished, it is necessary to clean the coating head and the coating plate in time to ensure the long-term stable operation of the coating equipment.
