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.
The ISP-3000 industrial-scale ultrasonic liquid processor is designed for continuous high-volume commercial production. Capable of outputting up to 3,000 W of acoustic power, the processor is supplied with an ultrasonic generator, a water-cooled transducer, a Barbell horn and a transparent or stainless steel reactor chamber (flow cell). ISP-3000 provides extremely high ultrasonic amplitudes and cavitation intensities during the continuous manufacture of a wide range of products for multiple industries. Some examples include the production of nanoemulsions, nanocrystals and liposomes for pharmaceutical, cosmetic, food, ink, paint, coating, wood, metalworking, nanocomposite and fuel industries, as well as wastewater purification, plant oil extraction, production of biofuels, crude oil desulphurization, liquid degassing, cell disruption, and many more.
Nano-emulsification of water in oil has been carried out using a 1200 W ultrasonic system manufactured by Industrial Sonomechanics, LLC. A common converging ultrasonic horn (tip diameter 15.6 mm) was used in the first part of the video, producing 40 ml of the nano-emulsion. A Full-wave Barbell horn (tip diameter 35 mm) was used in the second part of the video, allowing to scale up the volume of the formulation by a factor of 5, thereby producing 200 ml of the nano-emulsion. The ultrasonic amplitude delivered by both horns was 60 microns.
