Subject: Re: [rp-ml] Looking for information about Ramco cleaning station
I would not use isopropanol in a cleaner designed for TPM.??
TPM has low volatility, whereas?isopropanol is very volatile.? Not only would you get very high losses due to evaporation, but run the risk of a fire or an explosion from the vapour!??
Ideally, if you use IPA you should ensure the extraction fan has an explosion-proof motor (i.e. one that doesn't make sparks!).
Most people use TPM at room temperature.
There was a presentation at the 1997 Users' Group Meeting in Orlando on how to measure the level of resin in TPM.? The presentation was by Troy Kuhn from Chrysler and Mark Wynn from Yamazaki.? Tom Sorovetz kindly sent me a copy of this?presentation recently?(via Steve Deak!), and I attach a copy:

Dear list,
?
We are currently looking into the possibility of cleaning
our SLA parts with a Ramco cleaner but still have some
questions pending.
Hopefully someone on this forum can shine a light on
the doubts I have.
?
1) Would a cleaner that is built for use with TPM also
??? work with Isopropanol?
2) If working with TPM, what working temp. is optimal?
?? ( Is the temp. adjustable with the unit? )
3) What would be a typical usage of TPM before it
?? gets saturated and doesn't clean well anymore?????
4) Can TPM be recycled, or should it just be sent to
?? a company that takes care of residuals?
?
Any more info is highly apreciated!
Thanks in advance,
?
