Define particle size as part of process optimization

For viscose manufacturers, undissolved particles in the viscous solution are a problem because they can clog both the filters of the viscous solution and the nozzles in the spin bath. The processability of viscose mills is therefore negatively affected by the presence of particles.

Cause

We have a complete chain of pilot equipment from wood to finished viscose wire and the assignments in this area are increasing for us. Since we manufacture viscose solution in our viscose pilot, it is important to be able to measure its various properties such as the presence of particles and their size distribution. It is possible to evaluate different raw materials, types of dissolving celluloses, and process parameters in a good way.

The possibility of being able to measure the particle size is not limited to viscous solutions but can be used in many other contexts. In addition to measuring particles, the device can also measure cells, such as yeast cells.

Method

The particle size meter Multisizer 4 from Beckman Coulter works according to the Coulter principle and can detect particles in the size range 0.4 to 170 µm, but it can measure up to 1600 µm with several additives.
