Bench top cheap price ultrasonic spray coater for fuel cells nano thin film coating
Ultrasonic nozzles operate by converting high frequency sound waves into mechanical energy that is transferred into a liquid, creating standing waves. As the liquid exits the atomizing surface of the nozzle, it is broken into a fine mist of uniform micron sized droplets.
Unlike pressure nozzles, ultrasonic nozzles do not force liquids through a small orifice using high pressure in order to produce a spray. Liquid is fed through the center of a nozzle with a relatively large orifice, without pressure, and is atomized due to ultrasonic vibrations in the nozzle.
Every ultrasonic nozzle operates at a specific resonant frequency, which dictates the median droplet size. For example, a 60 kHz nozzle produces ,a median drop size of 20 microns (when spraying water). The higher the frequency, the smaller the median drop size.

ADVANTAGES:
* Uniform spraying: ultrasonic can make particles to micron or even nanometer level, smaller particles ensure more uniform spraying effect.
* Layer thickness controllable: ultrasonic spraying can accurately control the flow rate, so as to control the thickness of the layer.
* Saving materials and environmental protection: ultrasonic low flow rate spraying can reduce 80% of the use of spraying materials, workers do not need to directly contact the spraying materials, more environmental protection.
* High efficiency and energy saving: the liquid is transmitted to the spray head through self gravity or low pressure pump and continuous or intermittent atomization, no blockage, no wear, no noise, no pressure, no moving parts, no need for cooling water in atomization, little energy consumption, simple equipment, low failure rate, ultrasonic sprinkler has self-cleaning function and maintenance free.
