Set your operation up for success by ensuring your employees are properly trained on corona treating fundamentals and best practices. Enercon’s website provides you with free webinars<\/a>, how-to technical guides<\/a>, and a dedicated support website<\/a>. This article provides you with links to in depth content on 5 of the most popular topics film extruders and converters are interested in. <\/p>\n\n\n\n

    \n
  1. Understanding What a Corona Treater Actually Does<\/strong>
    Corona treaters ionize air in between a 1\/8\u201d air gap between two dielectrics. When films pass through the zone of ionized air, the corona treatment increases the substrate\u2019s surface energy which promotes its ability to bond with inks, coatings and adhesives.     Learn more here.<\/a><\/li>\n\n\n\n
  2. What Is the Proper Way to Conduct a Dyne Test to Measure Surface Energy?
    <\/strong>Most operations use dyne level testing to measure changes in surface energy after corona treatment. Two important things to remember are to ensure consistency when conducting dyne tests, and that reaching a desired dyne level does NOT guarantee adhesion. Dyne test results are subject to interpretation by the operator conducting the test.     Learn more about best practices for dyne testing here.<\/a><\/li>\n\n\n\n
  3. Best Practices for Web Handling<\/strong>
    When it comes to corona treating, the importance of web handling is often overlooked. Yet, ensuring substrates are properly presented to the corona treater is critical for corona treating success. Film scratching, stretching and static build-up are issues that can arise from improper web handling. Additionally, backside treatment, under-treatment and inconsistent treatment can be caused by poor web handling.     Learn how to ensure proper web handling here.<\/a><\/li>\n\n\n\n
  4. Symptoms of a Corona Treater in Need of Maintenance
    <\/strong>If your operators are trained to know what to look for when working with a corona treater, they can spot problems before they happen. For example, dirt and grime build-up on a ground roll can lead to high voltage arcing or backside treatment. If your ceramic electrodes are failing, there is a good chance they are overheating because there is an issue with the system\u2019s exhaust airflow. It could stem from lack of maintenance of the electrode assembly or be an issue with the exhaust path or blower.     Learn more.<\/a><\/li>\n\n\n\n
  5. What Do You Do When You Get the Results You Don\u2019t Expect?
    <\/strong>If you are running an application that you have had success with before and are seeing results you did not expect, ask this important question: \u201cWhat\u2019s changed?\u201d<\/em> Is the power setting and line speed the same as it was the last time you ran the job? Is the film the same? If the problem is with the dyne level, try running the job at half speed. If this improves the dyne level, it\u2019s likely there is something different with the film.     Learn how to troubleshoot corona treating issues here.<\/a><\/li>\n<\/ol>\n\n\n\n
