Ultrasonic Atomizer Nozzle Spray Coated Technology

Description:

Ultrasonic Atomizer Nozzle Spray Coated Technology, also known as ultrasonic nozzle, is an ultrasonic atomization spraying device based on the principle of Langzhiwan transducer. The maximum amplitude of ultrasonic waves is designed at the tip of the nozzle. When the liquid is transported from the rear of the nozzle to the tip, it is torn apart into small droplets by the high-frequency ultrasonic oscillation at the tip, forming atomization. Then, a certain amount of carrier gas can be used to deliver the liquid mist to the sprayed object or specific space. Under the condition of not exceeding the limit, the liquid atomization amount is only determined by the liquid delivery amount and the working frequency of the ultrasonic spray head

Improve Spray Efficiency :

To improve the ultrasonic atomization spraying effect of high viscosity liquids, the following methods can be tried:

1. Change the temperature of the liquid, which is an important factor affecting the viscosity of the liquid. Generally speaking, the higher the temperature, the lower the viscosity. Therefore, by heating or preheating the liquid, its viscosity can be effectively reduced, thereby improving its fluidity and ultrasonic atomization spraying performance.

2. Increase ultrasound power and reduce operating frequency. Ultrasonic power and operating frequency are important factors affecting ultrasonic atomization spraying. Through years of practical experiments, a power range of 2-20w has been developed; Different ultrasonic atomizing nozzles with frequencies ranging from 40 to 120kHz are designed to suit the characteristics of different liquid materials and ultimately meet customer requirements for coating preparation.

3. Use dual or multi flow ultrasonic atomizers. Dual flow or multi flow ultrasonic atomizer refers to an atomizer that mixes air flow and liquid flow at the outlet of the ultrasonic atomizer before atomization. The advantage of this atomizer is that it can utilize the force and turbulence of the air flow to make it easier for the air flow to break into small droplets. Therefore, using dual or multi flow ultrasonic atomizers can effectively improve the ultrasonic atomization spraying effect of high viscosity liquids.
