Sono-Tek Presents Ultrasonic Atomization Technology
November 24, 2008 |Estimated reading time: 1 minute
MILTON, N.Y. Sono-Tek debuted two ultrasonic systems for dispensing and depositing nano materials on target substrates to the nanotechnology market, targeting use on aerospace, homeland security, energy, biomedicine, and electronics manufacturing applications.
Sono-Tek's systems reportedly are accurate and cost-effective dispensing and depositing systems for nano materials. The proprietary SonicSyringe is an ultrasonic atomization dispersion syringe pump. The other system is a proprietary ultrasonic atomization spray nozzle.
When conventional mixing devices and pumps are used for dispensing nano particles, they tend to agglomerate and separate from the liquid suspension, Sono-Tek reports. The SonicSyringe imparts ultrasonic energy to break down and eliminate agglomerates that have formed during earlier handling. It keeps the nano particles continuously suspended in a uniform and homogenous mixture, creating a steady-state dispensing process.
When conventional pressure spray coating and Web printing technologies are used to coat nano particle on substrates, their uniformity control is limited and the amount of nano material that must be used is excessive and costly, the company asserts. Sono-Tek ultrasonic spray nozzles are designed to uniformly and accurately coat a thin layer of nano particles on substrates of different shapes, forms, and sizes.
Examples of successfully commercialized applications include fuel cells, solar panels, biodegradable food packaging, functional textiles, specialty glass, and biological and chemical sensors.
