1.Ultrasonic expertise in microporous cleaning
Anilox rollers, although there are metal rollers and ceramic rollers, but rely on the fine mesh cavities used to store ink, to the ordinary 600L / ICH anilox rollers, for example, its mesh cavity aperture in about 30 microns, the general cleaning tools are difficult to have such a fine into the mesh cavity cleaning; and ultrasonic generated by the diameter of the water bubble in about 2-5 microns, in a single mesh cavity at the same time can enter 6-15 bubble physical impact The bottom of the net cavity dirt, so as to achieve the purpose of a thorough cleaning, which is not other cleaning methods can be compared. At present in the world basically micro-hole cleaning are using ultrasonic cleaning machine, the application of a very wide range.
2. Ultrasonic cleaning effect is more thorough
The principle of ultrasonic cleaning is the ultrasonic transducer in the work, the production of hundreds of millions of naked eye can not see the water bubble, dense and evenly around the anilox rollers, whether it is a flat or depressed point, as long as the water bubble can enter contact, it can bring the dirt away. The role of the cleaning solution is to activate the adsorption of dirt in the anilox, so that the adsorption capacity is reduced and easily carried away by the bubbles generated by ultrasound, thus achieving the purpose of thorough cleaning. At the same time, the ultrasonic generated bubble is through the impact with the dirt, belongs to the physical role, while the cleaning solution is to reduce the adhesion of the dirt role, belongs to the chemical role, like Western medicine is the treatment of symptoms, Chinese medicine is the same reason, the combination of physical and chemical principles, making the cleaning more thorough and reasonable; this is also other cleaning methods do not have the advantages.
3. Not easy to damage the anilox rollers
Ultrasonic generated by the tiny bubble into the net cavity, hit the pure physical force of the cleaned object is limited; impact energy is controlled by the power and frequency of the ultrasonic generator, for the object being cleaned is different, the choice of technical data is also different. Through the control makes the cleaning process to reduce the damage to the anilox roller to a minimum.
4. More convenient operation, more environmentally friendly
Ultrasonic cleaning is a green method of changing electrical energy into kinetic energy, no dust flying and sewage flow, the only consumable is the cleaning solution to help increase the activity of dirt, easy to detach under the action of the water bubble; the whole cleaning method is very simple, after injecting the cleaning solution into the tank into the anilox rollers, press the cleaning switch can be; choose to meet the environmental protection of the cleaning solution, you can directly discharge the drain.
5. And other cleaning methods of comparison
Anilox roll cleaning although there are many other cleaning methods: the use of caustic soda or strong alkali heating cleaning, high-pressure gas sandblasting or baking soda dry powder direct injection cleaning, but at present, or the use of ultrasonic cleaning machine is relatively safe and good results. Three kinds of cleaning methods are compared as follows.
1) alkaline or heating cleaning, belongs to the pure chemical effect, the advantage is the price is low, but the metal anilox rollers easy corrosion is not suitable; although the ceramic to strong alkali has a certain anti-corrosion ability, but in the heating process anilox rollers of the metal base stick heat expansion, easy to make the outer layer of ceramic cracking, long-term use of strong alkali will also damage the ceramic.
2) High pressure air blasting sand or baking soda dry powder direct jet cleaning, is a pure physical impact on the surface of the anilox roller, there is sand or powder particles of uneven thickness and can not enter the depth of the cavity, the high line number of anilox roller is not easy to clean thoroughly; and direct high-pressure jet, long time use is easy to collapse the anilox roller mesh wall.
3) the use of ultrasonic cleaning machine, is a combination of chemical and physical effects, fine bubbles can directly enter the cavity, can clean the high line number of anilox rollers; cleaning fluid is neutral or weak alkaline, ultrasonic generated by the impact of the bubble is very small, the relative damage to the anilox rollers may seem very little
