[0002] The electrolytic capacitor anode aluminum powder corrosion expansion device is a special equipment used to expand the effective surface area of ​​the electrolytic capacitor anode aluminum foil.

However, the electrolyte usually contains some chemical substances, which may volatilize or leak during the corrosion process, thereby polluting the air. If the device is not well sealed, these harmful substances may escape into the environment, posing a potential threat to the health of the staff and the ecological environment.
