Advantages of Corona Generators
Ozone resistance: Heat and ozone generated on the dielectric surface have an erosion effect on most materials. This erosion reduces wall thickness and can ultimately result in insufficient dielectric strength and abrupt failure of the system. Dielectric materials used in corona treating applications must have high resistance to heat and ozone.
Cut resistance: Corona treaters operate in harsh environments that result in physical abuse that can lead to dielectric failure. Knife cuts, splices, friction from the web, drops, and banging all can have detrimental effects on the dielectric covering. It must be hardy enough to stand up to that abuse.
Heat dissipation: As the dielectric-covered roll rotates, it loses heat by radiation and convection. A material that readily dissipates heat is essential. If a dielectric material cannot dissipate heat normally, or if there is insufficient cooling due to the corona system design, burning is possible. Bare roll systems use a forced air cooling method vs. the convection cooling seen on conventional conductive stations. Properly sized dielectric surfaces determined by the correct choice of material are a necessary requirement to avoid heat dissipation.
Porosity: Dielectrics materials commonly have problems with porosity despite of the electrode covering. Porosity refers to the air entrapped in the coating, which can be a primary cause of roll failure. Porosity also relates to absorption of moisture, which can result in tracking of the electrical discharge to the ground, causing shutdown of the power source.
How Corona Generators Work
Corona Discharge:
An electrical current ionizes the air around the object being treated.
Surface Modification:
Charged particles from the plasma attach to the object's surface, altering its chemical properties.
Plasma Formation:
This creates a non-thermal plasma, a gas containing ions and electrons.
Ozone Production:
In ozone generators, the ionized oxygen forms ozone (O3), which then serves as a powerful disinfectant and oxidizing agent.

The operation of corona treatment generators involves the transformation of various materials and ingredients into finished products. Plastics such as polyethylene, polypropylene, and polyvinyl chloride are commonly processed, each offering distinct properties suitable for different applications. Rubber materials, including natural and synthetic variants, are also extensively utilized, especially in automotive and construction industries. Additives such as stabilizers, colorants, and fillers are integrated during processing to enhance material characteristics and product performance. The choice of materials and their compatibility with corona treatment generators directly impacts the quality and durability of the final output, making material selection a critical aspect of the manufacturing process.
Regularly check the distance between the electrode and the roller to ensure it falls within the standard range.
Periodically clean the electrodes and insulators: You can use a brush or a cloth dipped in alcohol for cleaning, but avoid using corrosive solvents. Regular cleaning, especially during high humidity seasons, is essential.
Avoid collisions and compression during use.
Keep the electrodes dry to maintain optimal discharge performance and prevent potential sparking issues.
Application of Corona Generators
High-speed wide blown film, spray bonding, extrusion, printing, compound, glue spreading, coating, box-pasting and other special industries, on the pretreatment of plastic.
