Mounted
on the m-VROC viscometer, the E chip attains 2,000,000 1/s measurements of
water-like viscosity or 1,000,000 1/s for various injket inks (~ 4 mPas).
Industrial processes
such as inkjetting, coating, printing and injection include high shear flows.
Paper coating, inkjetting, and engine lubrication engage shear rates over
1,000,000 1/s.
With
conventional viscometers, viscosity measurement at high shear rates has been
very difficult. With conventional instruments, the flow becomes turbulent or
unstable that invalidates measurements. Measurements have to be repeated, using
more samples and other resources.
Using the E chip
eliminates the onset of early turbulence. The well-defined, micro-fabricated
uniform flow channel of the E chip maintains the laminar flow at high shear
rates, producing accurate measurements. This viscosity measurement is
facilitated by the higher full scale pressure of the chip.
In
summation, the NEW E chip provides a greater range of shear rates, is more
stable and more accurate, which makes the process more consistent and
productive.
