| Diffusion of vapor through polymers |
Posted by Michael on
Hello,
Nice website...it's exactly what I need...
I'm doing research in application in which a polymer mebrane
(eg PP, 2,5mm) seals a hot water tank (--> direct
contact of hot water and polyprolyene). The temperature in the tank varies between 40°C
and 95°C over one year.
I would like to calculate
the diffusion of water out of the tank.
How do you think I could do it?
Any hint is welcome as I don't know much about diffusion. I read your theory
part, but couldn't associate it with my application.
In building engineering,
the number of diffusion resistance µ is known. Like I found in "Verfahren zur ein-
und zweidimensionalen Berechnung
des gekoppelten Feuchtetransports
in Bauteilen mit einfachen Kennwerten"
Dissertation at the university of Stuttgart/Germany by Künzel
1994, it is dependent of the solubility and the system temperature and the relative
humidity. But I don't know the exact relationship.
I'm
looking forward to reading any comment
Michael
