High efficiency electrode in stainless steel or ceramic for most printing and lamination applications requiring refreshment of pre-treated substrates or post-treatment of un-treated substrates.
Corona principle and role
Use high-frequency high-voltage on power pole in the discharge between the rollerand corona, low temperture plasma formed by iionization of air between the ploes to produce ozone,which is a strong oxidizer, can change the molecular structure of plastic surface to make it non-polar into polarity. at the same time after the corona treating, it will cause uneven surface hole roughen,it will enhance surface activity, such as the increase in surface tension, that is , ink,glue,etc,willbe able to further penetrate the materials and processed to achieve the idea effect on the printing and glue application.
elelctrode is a very important accessories in corona
Ceramic electrodes must be handled more carefully than metal electrodes. They must be protected from collisions with large substrate splices, tools and any other abrupt contacts. Damage resulting from physical shock is usually manifested in a significant break around the circumference of the ceramic tube. This type of damage is almost always fatal to the electrode and it must be immediately replaced.
advantage:it can treat both conductiveand insulatied material,such as metal film, laser film, aluminum foil,. aluminum plating film barcode label, metal labels.Uniform discharge, saving electricity.
