Ultrasonic cleaning machine in the surface treatment industry and the principle of application

Ultrasonic cleaning machine is widely used in various applications, commercial medical and other aspects. But I know that many people do not know much about ultrasonic cleaning machine. The following is a small introduction to the ultrasonic cleaning machine in the surface treatment industry and the principle of the application. I hope you can gain something after reading.

1、Application in the service industry. In daily production, glasses, jewelry can be cleaned with ultrasonic, fast and non-destructive. Large hotels and restaurants use it to clean tableware. It not only has a good cleaning effect, but also has the effect of killing viruses.

2, the application of ultrasonic in the pharmaceutical industry, ultrasonic cleaning technology has been widely used in many pharmaceutical companies after the application, especially vials, oral liquid bottles, ampoules, large infusion bottles cleaning, as well as the cleaning of butyl rubber stopper, is or has been recognized. For bottle cleaning, the use of ultrasonic cleaning technology instead of the original brushing, through the inversion of water injection, ultrasonic cleaning, internal and external rinsing, air-drying, turning and other processes to achieve.

3, ultrasonic cleaning of metals is well known. After extrusion of metal bars into wire, metal wire often has a layer of carbonized film and oil on the outside. It is difficult to remove the dirt with acid washing or other cleaning methods, especially the whole coil of wire. Ultrasonic wire washing machine is a kind of continuous wire feeding and efficient cleaning equipment designed according to the actual production needs. The rough washing part is composed of cleaning liquid storage tank, transducer, circulation pump, filter and supporting piping system. After the rough and fine washing of metal wire by ultrasonic, blowing dry, to complete the entire cleaning process. The whole set of equipment is integrated and controlled, simple, convenient and effective. Widely used in tantalum wire, tungsten wire, molybdenum wire, niobium wire, copper wire and other metal wire (before coating insulation paint).

4, ultrasonic cleaning technology in the application of phosphating treatment. Product spraying pre-treatment process is very important. General traditional process using acid treatment workpiece, resulting in serious environmental pollution and poor working environment. At the same time, the disadvantage is that the structure of complex parts acid cleaning and rust removal after the residual acid is difficult to clean. After the workpiece is sprayed, rust stains appear along the cracks for a short time, damaging the coating surface and seriously affecting the product appearance and internal quality. After applying ultrasonic cleaning technology to the pre-painting treatment, not only can the dirt and crevices on the surface of the object be quickly stripped, but also the coating layer of the painted parts is firm and will not return to rust.

The principle of ultrasonic cleaning machine surface treatment

Ultrasonic cleaning belongs to physical cleaning. The cleaning solution is put into the tank, and ultrasonic waves are applied in the tank. Since ultrasonic waves are a sparse vibration wave like sound waves, the pressure of the medium changes alternately during the propagation process. In the negative pressure zone, the liquid produces tearing force and forms vacuum bubbles. When the acoustic pressure reaches a certain value, the bubble rapidly expands, and then the bubble is squeezed and closed due to the pressure of the positive pressure zone. At this point, the liquid collides with each other, producing a powerful shock wave. Although the displacement and velocity is very small, but the acceleration is large, and the local pressure can reach several thousand atmospheres. This is the so-called cavitation effect.

The above is a small introduction to the ultrasonic cleaning machine surface treatment principle and application of all the content. Here, I want to remind you of several factors that affect the cleaning effect, such as frequency, temperature, sound intensity, cleaning fluid, location and other reasons. So you can pay attention to these factors, so that the cleaning effect is better. I believe you now have a better understanding of the ultrasonic cleaning machine.
