Product Overview

Description

Corona application

Corona treatment is known as dielectric barrier discharge. It is mainly used for surface treatment of

plastic film or plastic sheet. Before ink printing, laminating, blowing, coating, gluing, material

modification, polymerization, film metallization, casting and adhesions of the materials, in order to

make the surface have stronger adhesion (i.e. higher dyne level), and prevent the printing and gluing

from fading, dropping and other poor effects, it is necessary to use corona surface treatment.

 

Corona principle

OThe principle of the corona is to use high-frequency and high-voltage to generate corona between the

discharge electrode and the corona roller to form a low-temperature plasma area. Through air ionization

between the two medium, ozone is produced. Ozone is an oxidant, which can immediately change

the molecular structure of the plastic surface and make it from non-polar to polar. At the same time,

corona makes the surface of the material have small and uneven holes to rough the surface and enhance

the surface activity, after the surface tension is increased, so the ink, glue, etc. can deeply penatrate into

the material because of the treatment so it achieves the desired printing and gluing effects.

 

 

Features and advantages

* Corona treater is customized upon requirements, but the power control generator is almost the same.

* For non-conductive materials: PP, CPP, BOPP, PE, PET, HDPE, LDPE, PS, PI, PS, PC,

  PA, PVC, ABS, non-woven, synthetic paper, cartons, sheets and other materials;

* For conductive materials: aluminum foil, metallized film, cartons, sheets and other materials;

* For special materials: all kinds of the special-shaped materials;

* Hefeng Corona adopts stable, advanced and reliable imported IGBT which are the main components to control, trigger and display circuits with digital display, It's safe, reliable, durable with minumum faults. It has automatic protection such as over-voltage overload, over-current, short circuit and shutdown functions which is the most common trend in the world.
