1) Ultrasonic expertise in micropore cleaning.
Although there are metal rollers and ceramic rollers, but the fine mesh is used to store ink, to the ordinary 600L/ICH mesh roller as an example, the aperture of the mesh hole is about 30 microns, the general cleaning tools are difficult to have so small into the mesh hole cleaning; The diameter of the blisters generated by ultrasound is about 2-5 microns, and 6-15 blisters can physically impact the dirt at the bottom of the net at the same time in a single net hole, so as to achieve the purpose of thorough cleaning, which is not comparable to other cleaning methods. At present, the cleaning of basically small holes in the world uses ultrasonic cleaning machines, and the range of applications is very wide.
2) Ultrasonic cleaning effect is more thorough.
The principle of ultrasonic cleaning is that when the ultrasonic transducer is working, hundreds of millions of blisters that can not be seen by the naked eye are produced, densely and evenly around the mesh roller, whether it is a plane or a concave point, as long as the blisters can enter contact, they can take the dirt away. The function of the cleaning solution is to activate the dirt adsorbed in the mesh hole, so that the adsorption capacity is reduced, and the blister generated by the ultrasonic wave is easily taken away, so as to achieve the purpose of thorough cleaning. At the same time, the ultrasonic blisters are taken away from the dirt by impact, which belongs to the physical effect, and the cleaning solution is to reduce the adhesion effect of the dirt, which belongs to the chemical effect, just like Western medicine is to cure the symptoms, Chinese medicine is to cure the root of the truth, the combination of physical and chemical principles makes the cleaning more thorough and reasonable; This is also other cleaning methods do not have the advantage.
3) It is not easy to damage the roller.
The tiny bubbles produced by ultrasonic wave enter the net hole, and the pure physical force of impacting the cleaned thing is limited; The energy of the impact is controlled by the power and frequency of the ultrasonic generator, and the technical data selected are different for the different objects to be cleaned. Through the control, the damage to the roller in the cleaning process is reduced to a minimum degree.
4) More convenient operation, more environmentally friendly.
Ultrasonic cleaning is a green and environmentally friendly method to replace electric energy with kinetic energy, no dust flying and sewage flowing phenomenon, the only consumable is cleaning liquid, to help dirt increase activity, easy to escape under the action of blisters; The whole cleaning method is very simple, after injecting the cleaning liquid into the groove of the mesh roller, press the cleaning switch; Choose an environmentally friendly cleaning solution that can be discharged directly into the sewer.
5) Comparison with other roller cleaning methods
Although there are many other cleaning methods, such as the use of caustic soda or strong alkali heating cleaning, high pressure air sandblasting or baking soda dry powder direct injection cleaning, but at present, it is still relatively safe to use ultrasonic cleaning machine. The three cleaning methods are compared as follows:
A. caustic soda or heating cleaning, which belongs to pure chemical action, has the advantage of low price, but it is not suitable for corrosion of metal roller; Although the ceramic has a certain anti-corrosion ability to strong alkali, the metal base rod of the mesh roller is heated and expanded during the heating process, which is easy to crack the outer ceramic, and the long-term use of strong alkali will also damage the ceramic.
B. High pressure air sandblasting or baking soda powder direct injection cleaning, belongs to the pure physical impact on the surface of the mesh roller, there is a sand or powder particle thickness is not uniform and can not enter the depth of the mesh, the high number of lines of the mesh roller is not easy to clean thoroughly; And direct high-pressure injection, long-term use is easy to collapse the mesh roller wall.

C. The use of ultrasonic cleaning machine, is a combination of chemistry and physics, fine blisters can directly enter the net hole, can clean the high number of lines of the roller; The cleaning fluid is neutral or weak alkali, and the blister impact force generated by ultrasonic wave is very small, and the relative damage to the roller is very small.
