A question about static discharge
Hello I am new here
esd can just occur with human (I mean a human who cause discharge) or a substance which sensitive to static discharge can do it when there is a no
human ? (a substance which isolated through closed-tube)

your question is not clear but i try to answer the best i can..
Electro Static Discharges occur when the electrostatic resistance of a gas breacks down and ion and electron are allowed to be exchanged between two
opposite charges in order to restaure neutrality.
Various gases at various preassure have different potential at which this happen .
This phenomenon happens with or without human participant . in deep vacuum the resistance is so great that virtualy no charges are allowed to pass
under a thereshold of energy , this is verified in old x ray vacuum tube (cold cathode) as they become "hard" . air being absorbed by the inner glass
walls and reacts with the electrodes.
Hope this helps!

Thanks but I asked this question for solid sensitive explosives but Admin transferred my topic here it was in section of energetic
For example Tatp is a static sensitive explosives. For its is able to go off, a human is needed ?(can it just go off through a human who has enough
static electricity) I mean can it go off itself through static discharge when it is in a tube.

I would assume that your explosive, Tatp, explodes when the discharge strikes it directly. If it is inside a tube (metal), the discharge strikes the
metal and the charge dissipates.
As for the human, we get charged up when the humidity is low and you rub up again the carpet. So if you increase the humidity, it gets rid of this
problem.

We must attach the electrodes of knowledge to the nipples of ignorance and give a few good jolts.
Yes my evolutionary friends. We are all homos here. |

i dont think filling that stuff into a tube, assuming its somewhat conductive and in my mind it would be somewhat around PVC or steel is a really
great idea, unless if you actually want to die
however.....
you could carbonize sugar and get some ammonium nitrate, then mix 85% AP with 10% AN and 5% carbon from sugar, by weight
this is said to make the whole thing quite stable and very hard to set off with shock or friction, possibly also affecting static electricity
graphite has been added to flashpowder charges to decrease sensitivity
having 1kg dropweight dropping from max 100cm, i recall it added 10-20cm to drop height to add graphite to flashpowders
as you might have gotten confused.. in short:
add graphite, carbon and AN to your AP if you want to lessen the chances of accidental detonation, and most of all stop using metal or hard plastic
tubes, this also serves as massive danger factor for your sorroundings

I didn't ask that I ask that is it able to go off byitself there is a no human near its?
tatp can pick static then it discharge itself then it goes off, can it ? - I asked that
and a note this is not about just tatp you can think other static sensitive primary explosives
thanks.....

never heard about that.. without energy of some sort it wont gain energy
if you were to ampoulle it and let it stand around for +10 years i suppose it could give you an conclusive answer however
