MoRe has a particle size meter from Beckman Coulter, primarily for measurements of particle size in viscose dope. Our aim is to apply this technology also on other liquids where it is important to measure particle size and their distribution.
Undissolved particles in viscose dopes is a problem for viscose producers since they may clog the viscose dope filters as well as the nozzles in the spinning bath. The processability in the viscose mills is hence influenced negatively by the presence of particles, so the presence and amount of particles is an important quality measure for a viscose dope.
We have a complete set of pilot equipment from wood to finished viscose filament and the amount of assignments in this area is increasing all the time. Since we produce viscose dope in our viscose pilot it is important to be able to measure its different characteristics, such as the presence of particles and their size distribution. Buying this instrument means that we can evaluate different raw materials, types of dissolving cellulose and process parameters even better.
Particle size measurements are not limited only to viscose dope. The apparatus can also measure cells, e.g. yeast cells. This means that the interesting work to develop new applications for this meter now starts at MoRe.
The particle size meter works according to the Coulter principle and can with the detection tubes bought by MoRe detect particles between 0.4 and 170 µm, but it would be possible to measure up to 1600 µm with some added equipment.
