Corona treatment increases the energy of the surface of plastic films, paper and polymers in order to increase their permeability to promote the adhesion of inks, lacquers, varnishes and adhesives.
Treatment gives best results when a substrate is treated at the time of extrusion and on the production line before conversion.
The corona treatment increases quality and productivity since, after having carried out this treatment, not only will greater quality and speed be obtained in the printing, but there is also a smaller amount of waste.
The corona effect is an electrical phenomenon that occurs in the conductors of high voltage lines and manifests itself in the form of a luminous halo around them. Since the conductors are usually circular in section, the halo adopts a crown shape, hence the name of the phenomenon.
SOME OF OUR SYSTEMS
Rotating discharge system for FLEXIBLE PACKAGING:
Aluminum oxide body, stainless steel shell protection design, ozone and corrosion resistant. The connecting end of the high-voltage line is protected by anti-arc PTFE plate, which has high safety. The electrode adopts toothed ceramic electrodes imported from Germany to ensure good treatment effects on thin films, aluminum foils, copper foils, paper and other materials.
The discharge frame is equipped with integrated oil-filled bearing seats for all rollers, ensuring smooth operation and high positional accuracy. The electrode can be lifted laterally, making cleaning, maintenance and connection of materials easier. The rotating electrode discharge frame is equipped with a roller stop and electrode protection.
“Drawer type” discharge system for NARROW WEB:
The use of multiple sets of ceramic electrodes imported from Germany has good treatment effect on thin films, aluminum foils, metal films and paper rolls. The narrow drawer type corona treatment system adopts stainless steel outer cover and aluminum oxide plate design structure, which is resistant to rust and corrosion.
The electrode adopts a drawer slide rail installation way, which is convenient and quick for disassembly and assembly. Easy to clean and maintain quickly, and also convenient for mounting the materials to be treated.
The equipment is equipped with a roller stop and placed electrode protection.
