Description

Corona device for thin film

Technical Field

The utility model relates to the technical field of film processing, in particular to a corona device for a film.

Background Art

At present, the working principle of the corona treatment machine is that when a high voltage electric field acts on the surface of the film, the greater the electric field intensity, the easier it is for the electrons to be ionized, thereby forming electron-hole pairs. These electron-hole pairs will continue to move under the action of the electric field, and eventually form a corona discharge phenomenon on the surface of the film. The corona discharge phenomenon will produce a large number of active substances such as electrons, ions and free radicals. These active substances will react chemically with the surface of the film, thereby improving its surface properties.
