HW-CDF1 new design draw type corona treating station with ceramic discharge electrodes aluminum cover

Brief Introduction

Although corona treatment has been used in the manufacture and treatment of plastics for more than 35years, there was uncertainty for some time about the effect produced on the surface of the plastic, and about the corona process itself. After detailed research in this field, we know today that the corona treatment effect is based on bombarding the surface of the polymer with electrons. These leave the electrode and are accelerated under high tension towards the passing material web. In doing this they collide with air molecules which transmit light and react in part to ozone and nitrogen oxide. When the electrons come into contact with polyethylene, for instance, they have so much energy that they can break the bond between carbon-hydrogen or carbon-carbon. Reactions with the corona gas take place at these free radicals, mainly towards oxidation. The functional groups thus formed are polar and so provide the basis for adhesion of applied printing inks, lacquers, etc.

Main Features

1. The Germany-imported ceramic electrode is customized square, which ensures a good processing effect on thin film, aluminum foil, metal film, and paper coil.
2. The system adopts an all-aluminum structure, which is resistant to oxidation and corrosion.
3. The electrode is in the form of a drawer slide rail, which is convenient and quick to disassemble, easy to clean and maintain, and convenient for feeding and receiving materials.
4. The equipment is equipped with a roller stop and electrode protection.
