Corona Roll 4

1. Composition of corona Treater roller:

Corona treatment machine generally consist of  rubber rollers, electrodes, corona generators, rubber roller bearings, rollers and other parts. Among them, the Corona treater roller is a key component of corona treatment, and the electrode is used to connect with the corona generator during the working process. The corona generator can provide power to the electrode. The rubber roller bearings and rollers ensure the smooth operation of the corona rubber roller.

2. Working principle of corona Treater roller:

The corona treater roller uses high-voltage corona charge to generate corona discharge on the surface of the rubber roller to form a physical adsorption layer, thereby improving the contact performance of the medium between the rubber roller and the rubber roller. Corona treatment can change the chemical composition and physical properties of the rubber roller surface, thereby increasing its surface energy, enhancing its coating performance, and improving the surface performance of the product. Therefore, corona Treater rollers are widely used in printing, coating, laminating and other industries.

Application of Corona Treater roller:

It is widely used in printing, coating, laminating and other industries. In printing, the corona Treater roller can enhance the adhesion, remove dirt on the surface of the rubber roller, and improve the wettability of the rubber roller surface, thereby improving the printing quality. In coating and lamination, corona treater rollers can improve the uniformity, adhesion and wear resistance of the coating, thereby improving the quality of the coating. In addition, corona treater rollers can also be used for corona treatment of plastics, rubber and other materials.
