Working Principle Of Ultrasonic Spraying

Ultrasonic spraying

Ultrasonic spraying is a unique spraying technology, which is a spraying method based on ultrasonic atomizing nozzle technology. Compared with the traditional pneumatic two-fluid spraying, ultrasonic atomization spraying can achieve better uniformity, thinner coating thickness, and higher accuracy. At the same time, because the ultrasonic spray head can be atomized without the assistance of air pressure, the use of ultrasonic spraying can significantly reduce the splash of paint during spraying and achieve the purpose of saving paint. .

Ultrasonic atomization spraying equipment: use the energy of ultrasonic waves to break up water or liquid to form tiny particles with a size of several micrometers to more than 100 micrometers, to achieve humidification of air, liquid granulation, mixing, promoting chemical reactions, spraying, metal melting Institutional powder and other purposes.

Ultrasonic spraying principle

Ultrasonic nozzles work by converting high-frequency sound waves into mechanical energy, which is transferred into the liquid to generate standing waves. The liquid is introduced to the atomizing surface through the nozzle. When the liquid leaves the atomizing surface of the nozzle, it is broken into a fine mist of uniform micron-level droplets, thereby achieving atomization.

The ultrasonic atomizing nozzle is made of high-strength titanium alloy and other proprietary metals, which makes it excellent in chemical resistance and provides excellent acoustic characteristics. The electroactive element is contained in a sealed housing that protects the nozzle components from external contamination.

Advantages of ultrasonic spraying equipment

High uniformity: Ultrasonic spraying is a high-performance industrial-grade precision spraying technology for submicron and nano-scale thin film coatings with high uniformity.

Material saving and environmental protection: Because the unpressurized low-speed spray is easy to control, and the droplets fall on the substrate instead of rebounding from the substrate, it can ensure a significant reduction in the amount of overspray, which can save a lot of materials and reduce environmental emissions . Ultrasonic spraying has a coating utilization rate more than four times that of traditional two-fluid spraying.

High controllability: When extremely low flow rate is required, the nozzle is the most conceivable. When the spray particles are suspended, they have the unique advantage of keeping the particles uniformly suspended throughout the spray process by the ultrasonic effect of the nozzle itself to ensure that the functional particles are more uniformly dispersed in the thinner layer.

High efficiency and energy saving: the liquid is transferred to the spray head by its own gravity or low pressure pump and realizes continuous or intermittent atomization, no blockage, no wear, no noise, no pressure, no moving parts, no cooling water is required for atomization, and low energy consumption The equipment is simple and the failure rate is low. The ultrasonic spray head has a self-cleaning function and is maintenance-free on a daily basis.

Widely used: Ultrasonic spraying equipment is mainly used in fuel cells, thin film photovoltaic cells, thin film solar coatings, perovskite solar cells, solar cells, graphene coatings, silicon photovoltaic cells, glass coatings, electronic circuits and other industries. The nozzle can be applied to a variety of solutions, and sewage, chemical liquids, and oily mucus can be atomized.
