caustic cocktail

This discussion is exploding. There are so many things to pick up that it is getting out of hand, and will become boring for everyone else. It is diffusion, it is not 'lattice channels', the handsets problem is cracking, trace elements have limits ... these are distractions that take us away from the main point. PTFE is stable enough. If COF2 is generated at high temperature, it is destroyed on the stack.

I do not see the case made that we are at significant risk if we treat our kit sensibly.

I'll deal with this offline, if anyone needs. Alex?

Thanks,

I agree we should move off line or to another thread. I see a lot of inappropriate materials used in rebreathers, so I think this is a general issue that would be of interest to a wider group. However, we risk boring people, so lets start with an offline discussion as you suggest.

Just to avoid any confusion: the DIY handset problem I refer to is not cracking, it is porosity: see http://www.rebreatherworld.com/43453-post1.html. The reason this discussion started here is the hydrophobic membrane to protect a scrubber from a flood is after the after the scrubber stack so, so any offgasing products are not absorbed by the scrubber before they get into the lungs.
Anyhow, you have lots of interesting ideas, so lets talk offline unless someone else wants to debate this fine detail.
Cheers

No you are not boring me, at least.

Please keep your discussion online, I find it very interesting.
You could move it another thread, though.

OK

- wrong handset thread! Sorry. Bad material is another story.

If this reaction can be shown to occur, it needs to be dealt with. I think we lack the evidence.

No problem
