Reason for static Control static can cause several problems in a production facility.
In the film, extrusion for static can cause edges to curl and jam machinery.
In injection molding, the problem tends to be the attraction of dirt caused by static charge onto the part. Thus, creating painting and packaging issues.
Today there are many ways to eliminate the static buildup on parts. More powerful AC static bars and DC systems that can work farther away from the target product eliminating static charge. Neither requires any air.
Small packaged blower systems with air can assist in static control for very slow-moving production. Because introducing blower air, tends to be turbulent. The “ions,” pushing further, also re-combine. Especially as the distance grows if the target moves too fast,. There is insufficient time to eliminate the static simply because the ion concentration weakens.
Using the laminar flow of a compressed air-operated air knife or an annular air amplifier will push the “ions,.” Their re-combination will slow, but it still will weaken over distance.
So it should be with great caution when you come across claims of removing static from a target many feet away. Specifically when no time frame is specified, as the time needed can be quite long.
Even a static bar with no air behind it, several feet from a highly charged target, will still remove the static “given enough time” – again, a long time.
And in any production line, that exposure time is severely limited for obvious reasons.
Reason for Static Control With Air Suggested Products
The real reason for using high-pressure blowers with a static bar or compressed air-operated air knives like the Nex Flow® Ion Air Blade Ionizers and the Ion Blaster Beam® is cleaning.
If the distance is significantly considerable from the target or the static charge is exceptionally high on the target, the only way to remove the static and clean the part of dust and debris in a production line is to use a fixed bar or pin ionizer strong enough.
Providing a firm Ion Pin with their Ion Blaster Beam being mounted to a plastic attachment. By avoiding grounding, which can weaken the static elimination pin.
They have a standard and an extra strong static bar (which produces more ions for static elimination when dealing with a fast-moving and highly charged target) with their Ion Air Blade Ionizers.
When considering static elimination, try to avoid using air, especially if the purpose is solely for removing static charge, even if you cannot get close to the target.
But if cleaning is necessary, then an air source,, will be required with the static-eliminating device.
But do not get fooled that air alone, no matter what the source, will extend the range of the static eliminating “ions” without weakening the effect, thereby extending the time necessary for exposure to remove the static charge.
The only effective way to ensure static removal is cleaning from a distance. With a stronger concentration of static elimination ions.
