Anhydrous ultrasonic cleaning machine
Compared with the traditional cleaning method of anhydrous ultrasonic cleaning machine, it has the advantages of fast cleaning speed and high efficiency, and the solvent itself can be continuously distilled, regenerated and recycled; However, the shortcomings are also obvious. Because the production environment of optical glass requires constant temperature and humidity, it is a closed workshop, and the smell of solvent will have a certain impact on the working environment, especially when semi-automatic cleaning equipment is used.
In recent years, a new process has gradually matured, which is improved on the basis of traditional solvent cleaning. It effectively avoids some weaknesses of the solvent, is non-toxic and has a slight smell, and the waste liquid can be discharged into the sewage treatment system; There are few supporting devices on the equipment; The service life is longer than that of solvent; The running cost is lower than that of solvent. One of the most prominent advantages of semi-water-based cleaning agent is that it has a good cleaning effect on inorganic pollutants such as grinding powder, which greatly relieves the cleaning pressure of water-based cleaning agent in subsequent units, prolongs the service life of water-based cleaning agent, reduces the dosage of water-based cleaning agent and reduces the operating cost. Its disadvantage is that the cleaning speed is slightly slower than that of solvent, so it must be rinsed.
The principle of ultrasonic cleaning machine is to convert the high-frequency oscillation signal sent by ultrasonic generator into high-frequency mechanical oscillation through transducer and spread it to the medium-cleaning liquid. Ultrasonic waves alternately radiate forward in the cleaning liquid to make the liquid flow, resulting in tens of thousands of particles with a diameter of 50,500? M tiny bubbles, tiny bubbles existing in liquid vibrate under the action of sound field. These bubbles form and grow in the negative pressure region of ultrasonic longitudinal propagation, while in the positive pressure region, when the sound pressure reaches a certain value, the bubbles increase rapidly and then suddenly close. When the bubble closes, it will produce shock wave, and thousands of atmospheric pressure will be generated around it, which will destroy the insoluble dirt and disperse it in the cleaning solution. When the granules are wrapped by oil stains and attached to the surface of the cleaning parts, the oil will be emulsified and the solid particles will be separated, thus achieving the purpose of cleaning the parts. What do you mean here? Cavitation? In the process of action, the bubble closure can form a high temperature of several hundred degrees and an instantaneous high pressure above 1000 atmospheric pressure.
In fact, there are several ways about waterless ultrasonic cleaning machine. Cleaning before painting and cleaning after painting are all different cleaning methods, each with its own advantages, and the actual application depends on the actual situation.
