The Difference between Ultrasonic Spraying And Traditional Spraying

An ultrasonic spray nozzle, also known as an ultrasonic atomizer or ultrasonic misting nozzle, is a device that uses high-frequency ultrasonic vibrations to generate a fine mist or spray of liquid. It is commonly used in various applications such as coating, humidification, cooling, and spraying of liquids in industries such as pharmaceuticals, electronics, agriculture, and automotive.

The principle of ultrasonic spraying

It converts high-frequency sound waves into mechanical energy through a piezoelectric transducer, and then transfers the mechanical energy to the liquid. This longitudinal upward and downward vibration generates standing waves in the applied liquid film at the tip of the ultrasonic nozzle, where the amplitude of these waves Can be controlled by power generator. These stationary liquid waves can extend upward from the top of the ultrasonic nozzle, and when the droplets leave the atomization surface of the nozzle, they are broken down into a fine mist of uniform micron-sized or even nano-sized droplets.

Introduction to traditional spraying

Traditional spraying is a coating method that uses a spray gun or a disc atomizer to disperse the spray into uniform and fine mist droplets with the help of pressure or centrifugal force, and then applies it to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivatives of the above basic spraying forms, such as large-flow low-pressure atomized spraying, thermal spraying, automatic spraying, multi-group spraying, etc.

The difference between ultrasonic spraying and traditional spraying

Ultrasonic atomization spraying is an advanced spraying technology that combines the advantages of ultrasonic and spraying technologies to bring revolutionary changes to modern manufacturing. Through ultrasonic atomization spraying, we are able to achieve a more uniform and fine coating, thereby improving product quality and performance.

In the ultrasonic atomization spraying process, the vibration of ultrasonic waves can quickly atomize the liquid paint into tiny particles, and spray them onto the surface of the substrate through high-speed airflow. This spraying method not only improves the utilization rate of paint, but also enables more uniform coating distribution. At the same time, the vibration of ultrasonic waves can also form tiny gaps in the coating, making the coating more breathable, wear-resistant, and corrosion-resistant.

Compared with traditional spraying technology, ultrasonic atomization spraying has a wider range of applications. It can be used not only for spraying common materials such as metal and plastic, but also for spraying high-viscosity, high-solid content coatings, as well as spraying workpieces with special shapes and structures. In addition, ultrasonic atomization spraying also has the advantages of easy operation, high production efficiency, environmental protection and energy saving, etc., so it is widely used in automobiles, electronics, aerospace and other fields.

Ultrasonic atomization spraying is an efficient, precise and environmentally friendly spraying technology. It can not only improve product quality and performance, but also bring more sustainable development to enterprises. With the continuous advancement of science and technology and the continuous expansion of application fields, it is believed that ultrasonic atomization spraying will be widely used in more fields, injecting new impetus into the development of modern manufacturing industry.
