Static electricity grounding
Static electricity grounding
(OP)
Hello!
I have to ground several stocking silos made of 100% polypropylene fabric (the silos are filled with polystyrene beads). It doesn't contain any grounding wires included within the fabric. The silos are about 4x6x10 feets and their frame is made of metal pipes.
I am not familiar with static electricity and I wonder how much wires (connected to the ground) I should add on the silo's surface to remove most of its charges since I don't think that grounding only the frame will be enough.
And what kind of grounding rod should I use? (depth, size, etc) And what about the size of the gounding wire?
Thanks

RE: Static electricity grounding
The polystyrene beads will still carry charges, even in a fully metallic silo.
You'd almost be better off running a high humidity and snuff the charge that way.

It would be technically quite hard to raise the humidity level so I will consider it only as a last resort.
If we put a grounded metal grid through which the beads would pass, do you think it'd help?

For example, see:

RE: Static electricity grounding
It's otherwise not possible to remove the static, since just the flow motion of the beads will generate frictional static. And since the beads are non conductive, grids would not bleed off all the charge
