Paper Chemistry and Analytics

Sheet Former

Rapid-Köthen Sheet Former
Rapid-Köthen Sheet Former

With the Rapid-Köthen (RK) hand sheet former paper sheets can be produced in a laboratory scale.

Wax printer

Xerox ColorCube 8580
Xerox ColorCube 8580

The ColorCube 8580 enables the printing of different waxes onto paper substrates to create microfluidic channels and other wax surfaces.

Papermaking laboratory

Desintegrator for pulp and homogenization of pulp suspension.

Desintegrator

The estanit desintegrator can be used for pulp desintegration.

Size press

The Mathis SP 6513 size press is used to apply (polymer) coatings to paper substrates.

Steel drum dryer

The Formax E-100 steel drum dryer can be used to dry coated paper substrates.

Rollercoater

sumet coater

The Sumet rollercoater is used to create coatings with defined thickness on paper substrates. Furtheron the coatings can be dried or hardened via IR.

Drainage Freeness Retention Measurement (DFR)

The DFR is used for characterization of retention systems. Experimental results of retention and drainage are much closer to the real situation of industrial production on a papermachine compared to hand sheet forming. The optical sensor is able to directly measure filtrate consistency, ash consistencies, and thus eliminates time-consuming manual determination of stock.

Zeta Potential Measurement (SZP)

The SZP is used to characterize the surface charge of fiber and fillers. Zeta potential is obtained as streaming potential, conductivity, and the pressure (not from the electrophoresis, like with other instruments). Hence it is possible to characterize direct process samples without further, time-consuming treatment.

Particle Charge Detector (PCD)

Mütek Particle Charge Detector

The PCD measures the surface charge of dissolved or dispersed colloidal substances by polyelectrolyte titration. It is used to characterize the charge density of additives, detects anionic trash in process samples, and together with the SZP it is a useful tool, for understanding the interaction of fibers, charged additives and filler particles, respectively.
