New day, new courage. Thank you.
I agree, Frans, no movement allowed and no antistatic (conducting)
materials - that was a wrong turn I took.
There exists a "triboelectric series" (for instance:
http://www.trifield.com/triboelectric.htm) . Distance in this series
indicates propensity for charge buildup when materials are rubbed
together. Close enough and no discharge in air can be induced. Epoxy and
PE are not too far apart, closer than wool and PE (Phil, I see that PTFE
is at an extreme end of the scale). PE and PP are in the same place.
I am now inclined to go ahead with my bed either lined with very thin
HD-PE packing foam - to avoid all likelyhood of electrostatic discharge
- or not lined at all. Mechanically the second option looks most certain
- and simple.
Movement prevention using EPP padding where the tank has edges: at top
front (front and top faces), at top rear (top face) and bottom front
(front face of the bed).
The padding is not supposed to carry weight Thin layer of Araldite 420
(from a 2003 batch) bonds the stuff very well.
Any more thoughts welcome.
Cheers,
Jan de Jong
