Description

Technical Field

[0001] The invention relates to the technical field of printing presses, in particular to a secondary corona digital printing press. Background Art

[0002] Corona treatment is an electric shock treatment that makes the surface of the substrate have higher adhesion. Most plastic films (such as polycarbon films) are non-polar polymers with low surface tension. Known inks and adhesives cannot adhere firmly to them. Therefore, their surfaces are treated with corona treatment to break the chemical bonds of the plastic molecules and degrade them, increasing the surface roughness and surface area. A large amount of ozone is also generated during discharge. Ozone is a strong oxidant that can oxidize plastic molecules to produce highly polar groups such as carbonyl and peroxide, thereby increasing their surface energy. Existing corona treatment devices are usually set up as separate machines, requiring a complete set of unloading, corona, guide rollers, and winding devices, which take up a large amount of space, increase equipment costs, and have an additional production process, reducing production efficiency.
