Jack Frost, and Static, Just Will Not Let Go

As the weeks of March pass, we expect the weather to get better, but the last weeks of February has been brutal. Hopefully, Jack Frost will loss his grip as we move past the mid point of March. By the time this blog posts, it may be 60F degrees in Cincinnati, and I hope this blog is out of season. (Real time update – it will be 50F today)  In Ohio we had a fairly mild winter through December and January, but February was bitterly cold.  The bitter cold led to a few questions about static.

During cold weather the humidity in the air drops. This drop in humidity means that air can not dissipate static electricity as quickly as it does during warmer weather. Because static does not dissipate as quickly, industrial processes will create a much larger potential difference on rollers, winders, and web related products just to name a few. This potential will manifest itself in the static charges or shocks that we associate with rubbing your socks across a carpet floor. Getting into and out of your car can also be shocking experience. Shocks are one aspect of the static buildup, but the attraction and repulsion of static charges can wreck havoc on web applications.

If you have a process such as labeling, sheet feeding, or printing, that is jamming, curling, or tearing, you may have a static issue. But how can you be sure that static is causing your issue? A Static Meter! EXAIR 7905 Static Meter is a portable, non-contacting static meter that will allow you to accurately measure the static charge on large surfaces.  The meter will indicate surface voltage and polarity and is certified to NIST for accuracy and calibration traceability.

Once a static problem is identified, EXAIR has a number of Static Eliminators that can be implemented to neutralize the static and restore your manufacturing process to proper operation.
