1. The ultrasonic power supply converts 50/60 Hz to high frequency electrical energy. This electrical energy
is transmitted to the piezoelectric transducer within the converter, where it is changed to mechanical vibrations. The ultrasonic vibrations are intensified by the probe and focused at the tip where the atomization takes place. The liquid travels through the probe and spreads out as a thin film on the atomizing surface. The oscillating tip disintegrates the liquid into micro-droplets, and ejects them to form a gentle, low velocity spray.
2.Drop size is primarily a function of frequency, and the higher the frequency, the smaller the drop diameter.
A wide variety of coatings, chemicals, lubricants, and particulate suspensions can readily be atomized. However, factors such as viscosity, miscibility, and solid content deserve consideration. For optimum atomization, the viscosity should be under 500 cps and the solid concentration kept below 30%.
3.The applications include: Coating non-woven fabric, paper, etc.; laboratory spray drying; injecting moisture into a gas stream; applying minute amount of oil, fragrance or flavor onto a product; injecting small volume of reagents into a reactor;
