I came into the office today to find an interesting application in my inbox. A small plastic parts manufacturer was facing a problem when sealing their items inside of plastic bags. The problem arose from an inability to properly place a small strip of glue on the bags, resulting in unwanted glue on the parts and, at times, the exterior of the bags. What should have been a small strip of glue ended up as a random spread of adhesive due to a static charge on the plastic bags. So, they contacted EXAIR for a static solution.
In this application the first important parameter to check was the type of glue in use. Some glues are flammable and the vapors from them can be potentially ignitable, so making sure there was no risk for explosion was our first priority as our products are not recommended for use in potentially flammable or combustible applications.
After determining there was no risk for explosion, we then considered the application in more detail. The static solution needed to be small, effective, and there was an important aspect for this application – the solution could not have any airflow. The parts which are placed into these bags have low weights, and even a small airflow could remove them from the bags. So, we needed an airless solution that was compact and effective.
The solution was an Ion Point.
An Ion Point creates a small ionizing “zone” of approximately 2” x 2” (51mm x 51mm) without any airflow. At this distance, the static elimination from an Ion Point can dissipate a 5kV charge in 0.24 seconds. The small footprint and airless operation of the Ion Point made it an ideal candidate for this application.
By installing an Ion Point between the bag opener and the glue applicator, the static charge was eliminated and the process disturbance was removed. We were able to solve this problem, offering a readily available solution (from stock) that fit the specifics of the application.
As the temperature and humidity in the northern hemisphere drop, static problems become more prevalent. (Click here or here to read about why this happens.) If static problems arise in your facilities, consider an EXAIR solution. We’re available to discuss applications and solutions M-F, 8-5 EST.
