Ultrasonic Dispersion of Carbon Black in Water, 750 ml Batch
This video shows ultrasonic dispersion of a small amount carbon black in a medium-size batch of water. The process was carried out with a 1.2 kW bench-scale ultrasonic reactor equipped with a Full-wave Barbell Horn (FBH), produced by Industrial Sonomechanics, LLC (ISM). The ultrasonic amplitude during the process was 100 microns. The process can be directly scaled up by using ISM's industrial ultrasonic processors at the same operating conditions. All ISM's ultrasonic reactors can be used in a flow-through mode in order to ensure continuous production. Unlike other ultrasonic systems, our processors are able to generate high amplitudes and extremely intense ultrasonic cavitation even when using large-diameter industrial-scale ultrasonic horns and flow-through reactor chambers.
Ultrasonic Removal of Air Bubbles from Epoxy Resin
When epoxy resin is mixed, air bubbles are inadvertently introduced and must be removed. Ultrasonic degassing technique can be very useful in this case, as shown in this video. Ultrasonic removal of air bubbles from premixed epoxy resin is illustrated in this video. The experiment was conducted with a 1200 W ultrasonic reactor system produced by Industrial Sonomechanics, LLC.
Ultrasonic Cavitation in Water Produced by FBH, tip Ø = 75 mm
This video shows ultrasonic cavitation in water produced by a Full-wave Barbell Horn (output tip diameter = 75 mm) at a range of vibration amplitudes (from 10 to 150 microns). Unlike all other types of ultrasound horns, Barbell Horns (US Patent # 7156201) are capable of providing high vibration amplitudes and having large output tip diameters simultaneously, thereby allowing to implement high-intensity ultrasonic processes in the production environment. Most of the parts used in this demonstration were manufactured by Märkisches Werk Halver, according to ISM's intellectual property license.
