MÜTEK SZP-10 SYSTEM ZETA POTENTIAL

... KNOWS WHAT'S ON YOUR FIBER



The Mütek SZP-10 System Zeta Potential detects the surface charge of fibers and fillers. Measuring samples before and after contact with a chemical additive evaluates the efficiency, for example, of a starch or a wet strength agent in the papermaking process. The SZP is becoming a standard tool in the pulp and paper industry especially as process samples can be taken as they are, and do not have to be changed for e.g. electrophoresis.

By using BTG Software results obtained by the SZP-10 can be transferred in a database to administrate them and also compare them with measurements of the Mütek PCD-04 Travel.

Measuring Principle

The centerpiece of the SZP is a plastic measuring cell with embedded patented platinum electrodes. A fiber sample is drawn into the cell by applying a vacuum. At the screen electrode a fiber plug forms. A pulsating vacuum causes the aqueous phase to oscillate through the plug, thus shearing off the counterions and generating a streaming potential. The zeta potential is calculated by using the measured streaming potential, conductivity, and the pressure differential.

For pigment measurements, the SZP-10 is offered with a special set of electrodes.

Benefits

  • Know charge conditions of your fiber
  • Characterize fillers and pigments
  • Observe efficiency of functional chemicals
  • Optimize chemical dosage
