These general operating guidelines can improve the performance of any treating system.
1. Determine the treat level necessary for your product and its application as exactly as possible. A dyne level standard of plus or minus 2 dynes is generally acceptable in most applications.
2. Use the lowest possible power settings to develop the corona necessary to treat to the dyne level required.
3. Run the system as cool as possible to increase the service life of all electrical components.
DON'T OVERTREAT - Overtreating wastes power and generates excess heat, ozone, and other corrosive elements which can shorten the service life of the treater station and its components.
Check the generator settings when the following conditions occur.
1. Changes are made in the treating system, i.e., when roll covering is changed or when the electrode gap or width is changed.
2. Changes in the treat level are required.
3. Changes occur in the product treated, such as the addition of slip or other additives.
4. Changes occur in the line speed.
Mechanical Considerations:
1. Be sure the treater rolls run straight and true.
2. Be sure the gap between the electrode and the treater roll is even and concentric across the width of the web.
3. Adjust the air gap to no less than .060" and no more than .065", typically .062".
4. Adjust the electrode width so corona is formed only on the web.
5. Be sure the zero speed switch is connected and operating properly.
Match roll coverings for two-sided treat when one generator powers both electrodes. Since different coatings have different dielectric constants, a mismatch can cause an uneven distribution of power between the two rolls. This may result in uneven treat and premature coating failure.
