The state-of-the-art rheometer platform includes a broad range of accessories to handle new analytical requirements, including the RheoScope
module for micro viewing and the Haake Rheonaut module for FTIR analysis.
Rheological experiments were per formed using a stress controlled rotational rheometer (HAAKE RheoScope
) equipped with 25 mm parallel plates and using a gap thickness of 0.1mm.
The SER can be teamed with the recently introduced RheoScope
HT (High Temperature) module which simultaneously records theological properties and changes in the microscopic structure of a tested sample up to high temperatures.
A single-bore capillary rheometer (Rheoscope
1000; Ceast) was used with two capillary dies having length/diameter ratios of 10 and 40 (diameter = 1 mm).
Another instrument, the RheoScope
1, was also showcased.
1 features a unique combination of an optical microscope, digital camera and universal rheometer.
Rheological measurements were performed at 230[degrees]C in accordance with ISO 11443 using a piston-cylinder single bore capillary rheometer (Rheoscope
1000 Ceast 6742).
1, a combination of an optical microscope, digital camera, and universal rheometer, eliminates the need for multiple instruments, according to manufacturer Thermo Haake.
This rheometer manufacturer has introduced the Rheoscope
1, featuring a combination of an optical microscope, digital camera and universal rheometer.
At the higher shear rates a capillary rheometer, Ceast Rheoscope
1000, has been used with flat dies of [Phi] = 1 mm and length-to-diameter ratios (L/D) from 5 to 20.
The blends were extruded from the molten state (370 [degrees] C) using a Ceast capillary viscometer (Rheoscope
1000), and the fibers obtained were fractured in liquid nitrogen (-196 [degrees] C).
Rheological characterization of the materials was made using a capillary rheometer Rheoscope
1000 from CEAST (L/D = 40/1; D = 1 mm including rabinowitsch [TABULAR DATA FOR TABLE 1 OMITTED] [TABULAR DATA FOR TABLE 2 OMITTED] correction).
