Hello Graham, I was wondering if you could explain some causes of variation in the s' curve.
Basically the initial dip has a longer sustained plateau before s' starts increasing. There is no correlation in shift/batch times/weightment deviations/drop temps. Though batch time varies up to +/- 25...
I have 2 ply epdm membrane that is calendered, wound up into a cart separated by a liner.
Coming out of the cart/liner, one ply is always less tackier than the other
It's as if one of the ply looses tack? Liner is the same on both sides.
The gum properties are exactly the same right out of the...
Ah, thank you Graham. I have a couple more questions I'd like to ask.
What is the typical duration for a ram raise to vent? (if the purpose was to vent moisture)
For epdm, how many ram raises would one typically see for upsidedown mixing in a Banbury of
Master
Final
Single pass?
Looking at mixing graphs, the banbury ram goes up during a batch. What is the purpose of raising the ram instead of just continuing the mix with the ram down? Will this allow volatiles or moisture to escape?
