On the "loss" of galden,
I have processed 25 panels in the machine.. I put 500mL of Galden in it, to start with which put it up to about 3.5m in the tank.. after processing the 25 panels, i've needed to add 100ml of addtional fluid to bring it back to close to that level.
I've been doing some reading, and i suspect that Galden coudl be quite hydroscopic, so some of the "vapour" i saw escaping was not actually galden, but plain old steam. This is reinforced by the fact that after a couple of cycles on a day, there was no escaping vapour. However the next day ( after a 12 hour cold state ), the first run i got, it was steam again.. i suspect it sucks some water vapour in...
My best bet on the loss is actually that some of the fluid is condencing on the boards them selves, and i'm taking it out of the tank, on the boards themselves. Much of this i think could be solved by a tented lid, as quite a bit of it, is drops forming on the lid condensing and dropping back on my panels.
The process time is slow.. With two panels running in the machine, my cycle time was between 25 and 29 minutes.. Most of it, with the materials stting under 80C, so its not damaging them, but its too hot to touch...
After a weeks use, i'm 100% sold on the process, this implementation is just poor and needs work
