Any other information on results incl. tables
With granulometry the particle size distribution according to DIN 66165, April 1987 for sieves with a mesh size from 63 to 1400 µm, has to be determined.
Applicant's summary and conclusion
- Conclusions:
- The test item Fatty acid C16-18, sodium salt is a solid at room temperature with single particles and agglomerates. Within the sieve measurements the test item shows strong agglomeration especially close to the mesh sizes, bigger than 15000 µm. Due to the agglomeration the measured particle size distribution will differ from the real particle size according to the definition to DIN 66165.
