Questions
What is Molecular Weight Distribution (MWD) of material under process, polymerisation or mixing?
How I can get lower shear viscosity, but still melt strength must be at high level?
If I add 10% of low fraction polymer, what happens? What is viscosity at zero shear rate?
Relaxation Spectrum? Is there any Long Chain Branching (LCB) or crosslinks?
Many similar questions and needs are found in daily manufacturing and research.
Measure viscosity
We have to measure viscosity of material. Easiest this is done by a dynamic cone-plate rheometer
to get a complex viscosity flow curve as a function of frequency. In principle there is also
possible to use other devices and methods. You can do measurements at different temperatures
to get wider data range. Save data on a floppy or other media in ASCII or other form convertible
for RheoPower.
Import data
Import complex viscosity flow curve as a function of frequency. On the importing window is ready
by a single buttons click procedures for some rheometers’ data. You can also import GPC and
other MWD data for cross-computations and developments on the databases.
