Think Ahead, Treat it Right

Maintenance

As simple as it sounds, maintaining surface treating equipment goes a long way. “One of the biggest causes of downtime on a corona treater is due to improper cleaning. Many materials tend to leach slip and other additives during the corona process,” says Opad. “Corona treaters incorporate the use of exhaust blowers. Newer style treaters are often more open style designs, so that they tend to pull in the air, along with dirt from the surrounding area. All of this can get deposited on the electrodes and rollers.” He explains that this dirt buildup can also contribute to producing unwanted backside treatment, by causing high and low spots on the treater roll, enabling air gaps to be created.
