High-precision ultrasonic atomization spraying equipment Graphene Coatings

High-precision ultrasonic atomization spraying equipment Graphene Coatings

short description:

Ultrasonic atomization spraying equipment uses the piezoelectric effect of ultrasonic transducers to convert the electrical energy input by the ultrasonic generator into high-frequency mechanical energy. The mechanical energy is transferred to the liquid to generate standing waves. When the liquid leaves the nozzle, it is broken into uniform micron-sized fine mist droplets, thereby achieving atomization.

Equipment composition
Ultrasonic vibration components: including ultrasonic transducers, horns, tool heads, etc., responsible for converting electrical energy into mechanical energy of ultrasonic vibration and radiating ultrasonic waves.
Ultrasonic drive power supply: generates high-power high-frequency AC power, fully digitally controlled, and drives ultrasonic vibration components to work.
Motion system: such as XY dual-axis (and above) precision motion modules, with a comprehensive trajectory editing system, can realize the spray trajectory control of any two-dimensional plane graphics.
Liquid supply system: usually composed of precision metering pumps, ultrasonic dispersion liquid supply systems, etc., which can accurately control the delivery flow of liquid and stably deliver liquid to the atomizing nozzle.
Other auxiliary components: such as vacuum adsorption heating substrates, which can be used to fix and heat substrates; digital display carrier gas systems, which can provide auxiliary gases; fume hood-type equipment is also equipped with a top exhaust system to discharge excess exhaust gas and hot air.


Features
1.High coating uniformity: The tiny particles atomized by the ultrasonic nozzle can be more evenly covered on the surface of the substrate, and the spraying uniformity performance can reach more than 95%, which can avoid problems such as uneven coating thickness and color difference.
2.High coating thickness control accuracy: The flow rate of the coating liquid for atomization spraying is controlled by a high-precision metering pump to achieve a control accuracy of nanoliters per second, ensuring the accuracy of coating thickness control.
3.High raw material utilization rate: Ultrasonic spraying atomizes liquid through ultrasonic oscillation, does not require additional gas, reduces paint waste, and the raw material utilization rate is more than 4 times that of ordinary air spraying, up to more than 90%.
4.Strong adaptability: It is suitable for a variety of coating materials and substrates. Whether it is metal, ceramic or polymer materials, the ideal coating effect can be achieved by adjusting the ultrasonic parameters and the composition of the coating liquid.
5.Simple equipment maintenance: No cooling water is required during atomization, energy consumption is low, the equipment is simple, the failure rate is low, and daily maintenance is free. And the nozzle is not easy to clog, and it can be applied to a variety of solutions, even sewage, chemical liquids, oil mucus, etc.
