How to disperse nanopowder and nanoparticles?
1) Step 1, add surfactant / dispersant into solution first. Step 2, when surfactants / dispersants are fully dissolved into the solution, add nanopowder / nanoparticles. Step 3, finally, ultrasonicate the solution (this requires the customer's own experience).
2) During ultrasonic processing, the dispersion may heat up, therefore it is a good idea every 5min to stop, wait for solution to cool, defoam, before continuing. Total 30 minutes: 5min x 6 times. Speed should be 2000r/min
3) If you do not have ultrasonicate equipments, please use high speed mixers that also work very well (normally 20-40 minutes)
Making Nanopowder / Nanoparticles Dispersion Product Equipments:
(1) Ultrasonic dispersion device: ideal for laboratory-scale, low-viscosity media to disperse Nanopowder; (2) Grinding dispersion equipment: suitable for large-scale nanopowder dispersion product, middle-viscosity media to disperse nanopowder; (3) Combination method: "first grinding, second ultrasonic dispersion " can be efficiently and stably to disperse nanopowder.
***Equipment capacity / capability / power, dispersion volume, dispersion concentration also need to be considered...
