Just this week we embarked on the dreaded end of summer task of closing our pool. While it isn’t as nice to look at once the winter cover comes on, it sure beats skimming leaves out for an hour every day when the water temperature drops below a comfortable swimming temperature. However, as an avid Cincinnati Bengals fan and love for all things football-related, this time of year also brings with it excitement and optimism as we gear up for another NFL season. Times have been rough for Bengals fans (and all Cincinnati sports for that matter), but things are looking up for us in the football world with the arrival of the newfound hope that comes with a 3-1 record.
So, what do Cincinnati Bengals football and static have in common? Both share the same seasons, fall and winter. This time of the year it is not uncommon to feel a slight shock after walking across a carpeted surface and touching a door knob. This little “jolt” is a result of fast-moving electrons leaping from your body to the door knob, or vice versa. As your feet shuffle across the surface of a rug or carpet, your body will either gain or lose electrons. Touching a conductive surface then causes these electrons to leap from one place to another.
If you notice, this happens to occur much more often during colder winter months. The reason that you experience static shocks more frequently during winter is due to the relative humidity. At colder temperatures, air does not hold as much moisture as it does when it’s warm. Even though you’re heating your house to a similar temperature, the air that is being drawn into your home and heated is still the dry cold air containing less moisture.
The amount of moisture in the air is expressed as relative humidity. This value is given as a percentage of water vapor in the air, compared to how much it could hold at that temperature. In conditions of lower relative humidity, static charges build up much easier. When the relative humidity is high, there’s a higher concentration of water molecules present in the air. These water molecules “coat” the surface of the material, allowing electrons to move more freely and form a layer over the material. This layer of water molecules acts like a lubricant, reducing the forces that cause static to generate. There are many applications that static may only pose an issue once the climate changes.
To combat static electricity in your processes, EXAIR manufactures a complete line of Static Eliminators. Any of them are available to ship same day from stock to customers in the U.S. with an order placed by 2:00 ET (1:00 ET for same day shipments to Canada). We’re all tired by now of receiving the extremely long lead times for seemingly everything we try to order. That’s not the case here at EXAIR, if you need a solution and FAST give us a call!
