The benefits of ultrasonic spraying?
Spraying, as a surface treatment method, has been widely used in various industries. Although ultrasonic spraying machines are relatively expensive among all spraying machines, their economic benefits and excellent performance are incomparable to other spraying machines.
1. Material savings, ultrasonic spraying can maximize material savings, greatly saving costs, especially for expensive liquid materials. Due to the fact that ultrasonic nozzles do not require air pressure assistance to atomize, the use of ultrasonic spraying can significantly reduce the splashing of liquid materials during the spraying process, achieving the goal of saving liquid materials. The utilization rate of liquid materials in ultrasonic spraying can even reach more than four times that of other spraying methods. The most representative ones are fuel cell spraying and solar cell spraying.
2. Precision and controllability, some substrates require very high surface treatment requirements, and some even need to reach the nanoscale, which is completely inadequate for general spraying methods. Ultrasonic spraying is a unique spray technology. Liquid coatings are first atomized into fine particles by ultrasonic atomization device, and then uniformly coated on the surface of the substrate by a certain amount of current carrying gas to form a coating or film. The thickness of the coating film can reach several tens of nanometers, and can be precisely controlled by controlling frequency, atomization flow rate, and spraying frequency. For example, the recently popular spraying of balloon catheters and vascular stents has strict standards for the amount of drug liquid applied on them.
3. High uniformity, the uniformity of fine particles after ultrasonic spraying and atomization can reach over 95%, which other spraying methods cannot achieve. Moreover, the ultrasonic nozzle vibrates at a high frequency of tens of thousands of times per second during operation, making it non clogging and self-cleaning. For some solid particle suspensions, an ultrasonic dispersion system can also be configured to achieve online dispersion, stirring, and supply of liquid, avoiding the aggregation and precipitation of dispersed liquid during the spraying process.
4. For special applications, ultrasonic spraying can be competent for spraying work in some special fields. For example, in the medical industry, test tube spraying requires the formation of a thin and uniform coating on the inner wall of the test tube. Ultrasonic probe type nozzles can be used for atomization spraying.
In short, it is not unreasonable that ultrasonic spraying is becoming increasingly widely used. The price is relatively high, but it is worth it.
