|ELECTROMAGNETIC LAMINAR JET BREAKUP|
Principle of technologyIn the electromagnetic laminar jet breakup technique, a laminar jet of a precursor liquid passing a nozzle of appropriate diameter is broken into equally sized droplets by a superimposed mechanical vibration. The droplets are further processed into particles by crosslinking or polymerization (hardening process) of the precursor liquid. The hardening process must be very fast in order to achieve optimal particle quality. If no such fast hardening process is feasible (e.g. in cases where the hardening process is based on radical polymerization) the electromagnetic laminar jet breakup technology has to be combined with other technologies such as preenTec’s proprietary tandem process or a two phase system process. The electromagnetic laminar jet breakup technology gives a narrow bead size distribution. The particle diameter can be predicted and controlled by choosing the nozzle diameter, volumetric flow and superimposed frequency.Materials that can be processed
