How Ultrasound Works on Sonochemistry
Ultrasound has many effects, both chemical and physical. The chemical effects of ultrasound refers to understanding the effect of sound waves on chemical systems, which is known as sonochemistry. Sonochemistry is the application of ultrasound to chemical reactions and processes. The mechanism causing sonochemical effects in liquids is the phenomenon of acoustic cavitation. Cavitation phenomenon, that is, "the formation, growth and implosive collapse of bubbles in a liquid. Cavitation collapse produces intense localized heating 15000K, high pressure 11000atml, and enormous heating and cooking rates >109k/sec)" and liquid jets ( 400km/h)
Ultrasonic treatment can be used to produce nanoparticles, such as nanoemulsions, nanocrystals, liposomes and wax emulsions, as well as wastewater purification, degassing, extraction of seaweed polysaccharides and vegetable oils, extraction of anthocyanins and antioxidants, production of biofuels, crude oil desulfurization, Cell destruction, polymer and epoxy processing, adhesive thinning and many other processes. It is used in pharmaceuticals, cosmetics, water, food, inks, paints, coatings, wood treatment, metalworking, nanocomposites, pesticides, fuels, wood products and many other industries. Sonication can also be used to accelerate dissolution by breaking down molecular interactions. In biological applications, sonication may be sufficient to destroy or inactivate biological materials. For example, sonication is often used to disrupt cell membranes and release cellular contents. Sonication is the working principle that is also used in ultrasonic cleaning - loosening particles adhered to the surface, emulsifying oil stains, defoaming, etc. In addition to laboratory science applications, applications of ultrasonic cleaners include cleaning items such as eyeglasses and jewelry.
Ultrasonic laboratory and industrial equipment is used in different fields of application. Typically, a process is first tested on a laboratory scale to demonstrate its feasibility and to establish some of the desired ultrasonic irradiation parameters. After this phase is completed, the process is transferred to a pilot (bench) scale for flow-through pre-production optimization and then to an industrial scale for continuous production. Using Altrasonic ultrasonic laboratory and industrial equipment, the final product is maintained at an optimized level while increasing productivity.
