Testing technologies NDA VACU NON DISPERSIBLE MATTER (NDM) Mechanical flushing method – Functional principle according to ASTM D 7724 Test set NDA VACU for the analysis of sieve residue This test method covers the determination of non-dispersible matter after mechanical water flushing of carbon blacks (and other powder materials). Key features • High-quality, reliable and durable technology • Fully-automatic operating program The process provides information of the content of coarse impurities or constituents which are insoluble in water, such as ceramic constituents, metals or heavily compacted pigments. • Collecting tank 50 liters with integrated water pump (fully automatic) It delivers reproducible results even with the most difficult products. • No dust dispersion due to sealed construction The principle and the related test method have been developed to determine the non-dispersible matter on a specific class of carbon blacks called Mechanical Rubber Grades (MRG). • Handy sieves (diameter 105 mm) • Simplest sieve entry and removal • Absolute reproducibility of screening results • Glass vessel for observation of process • Easy maintenance • Automatic lifting system for vessel lid • Low noise level Customer satisfaction promise We offer worldwide installation and training services by our experienced engineers and technicians.
