Description
Ultrasonic precision spraying system is a surface precision ultrasonic spraying equipment that integrates ultrasonic atomizing nozzle, ultrasonic generator, liquid supply system, motion system, heating system, exhaust system, etc. Ultrasonic spraying is a spraying method based on ultrasonic atomizing nozzle technology. Compared with traditional air pressure two-fluid spraying, ultrasonic atomizing spraying can bring higher uniformity, thinner coating thickness and higher precision. At the same time, since ultrasonic nozzles do not require air pressure assistance to atomize, the low-speed droplets generated by ultrasound are easy to control, and the droplets fall on the substrate instead of being hit and rebounding from the substrate. Therefore, ultrasonic spraying can greatly reduce the paint splash caused by the spraying process, thereby greatly reducing the waste of paint. The paint utilization rate of ultrasonic spraying is more than 4 times that of traditional two-fluid spraying.
The ultrasonic nozzle consists of a liquid inlet part, a connection controller part, a transducer and a nozzle. The ultrasonic nozzle converts part of the high-frequency electrical energy into mechanical energy through the transducer and transmits it to the liquid to generate standing waves. When the liquid leaves the atomizing surface of the nozzle, it is broken into a uniform fine mist of micron-sized droplets.
Features

★ The spray impact is extremely small, and will not cause splashing or waste of raw materials
★ The uniformity of atomized particles is > 95%
★ Not easy to clog the nozzle
★ High-precision control of coating thickness
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 oil mucus can also be atomized.
1.Can ultrasonic atomization be used for heat-sensitive or volatile liquids?
Yes, ultrasonic atomization is particularly suitable for heat-sensitive or volatile liquids. The low-temperature operation and gentle atomization process help preserve the integrity and properties of sensitive substances.
2.Are there different types of ultrasonic atomizers available?
Yes, there are different types of ultrasonic atomizers available, including handheld atomizers, benchtop units, and industrial-scale atomization systems. The choice of atomizer depends on the specific application requirements and desired output volume.
3.How do I control the droplet size in ultrasonic atomization?
The droplet size in ultrasonic atomization can be controlled by adjusting parameters such as the ultrasonic frequency, power output, liquid flow rate, and the distance between the transducer and the liquid surface. Different combinations of these parameters can achieve the desired droplet size.
4.Can ultrasonic atomization be used for generating a controlled flow of mist?
Yes, ultrasonic atomization can be used to generate a controlled flow of mist. By regulating the liquid flow rate and the ultrasonic power, it is possible to achieve a consistent and continuous mist output for various applications.
5.Are there any safety considerations when using ultrasonic atomization?
When using ultrasonic atomization, it is important to ensure proper ventilation in the area to prevent the accumulation of mist. Additionally, some substances may require specific safety precautions, such as handling volatile or hazardous liquids in a well-ventilated environment and following appropriate safety guidelines.
