Accessory for MCR:
Immobilization Cell
- Accessory for “Additional Parameter Settings”
- Immobilization kinetics of paper coatings in real-time
- Liquid temperature control
The Immobilization Cell (IMC) is an accessory for Anton Paar’s MCR rheometers. It is designed to investigate the immobilization kinetics, water retention, and drying of paper coatings, paints, slurries, or other suspensions. The conditions of the production process are simulated by varying temperature, gap width, shear stress, and pressure difference (vacuum) directly in the rheometer. A vacuum generated by a pump forces the liquid phase of the sample to penetrate into the base paper so that the moisture is extracted from the coating. Changes in the rheological behavior of the sample during the immobilization process are measured and analyzed in real-time.

Key features
Enjoy a clean work environment and high throughput
Measurements with the IMC are performed using a parallel-plate measuring system with 50 mm diameter. The wetted parts are resistant and easily removable, which makes the cell easy to clean and increases productivity and sample throughput. For a clean working environment, a waste hose is included. The liquid temperature control is available from 0 °C to 70 °C and the vacuum pump is software-controlled. All recorded and calculated data as well as predefined workbooks are directly displayed in the rheometer software RheoCompass.

Choose between rotational or oscillatory tests
Via a simple stress-controlled rotational test, the increase in viscosity over time is used to characterize the sample’s immobilization kinetics. This is determined by the water retention properties of dispersion coating colors and the structural rearrangements during the dewatering process. As an alternative, also advanced measurements in oscillation can also be performed in order to analyze the change in the viscoelastic properties of the sample.

Optimize your paper production process
In the paper coatings industry rheometers are the perfect instrument for both quality control and research and development. Rheological tests can simulate real-life conditions in order to predict a paper’s behavior in manufacturing and in use. Typical samples:
- Printing paper
- Paperboard
- Paper for (food) packaging
- Paper labels
- Paper for other special applications
