1) The frequency of the ultrasonic cleaning machine should be cleaned within the range recommended by the manufacturer, with the best frequency obtained after many trials. The higher the ultrasonic frequency, the smaller the volume of bubbles in the liquid, the weaker the strength, the generally recommended frequency is 40KHz, at this frequency, the smallest bubbles will be produced deep into the net hole for cleaning. However, due to the nature of the roller and the design of the ultrasonic cleaning machine is different, this frequency recommendation is for reference only.
2) The temperature of the cleaning agent will also affect the cleaning quality, the temperature is high, the viscosity of the cleaning agent is low, the amount of bubbles in the liquid will increase, thereby increasing the ability of ultrasonic cleaning. The temperature of the cleaning agent should generally be controlled at 40 ~ 60 ° C, and the cleaning agent must be a special ultrasonic cleaning agent.
3) The time control of ultrasonic cleaning machine is very important, because the longer the time of ultrasonic emission, the more likely it is to damage the surface of the roller and the wall of the mesh hole. At present, many countries in Europe and the United States have a pre-treatment system, in general, to ensure that the safety of the roller cleaning time does not damage no more than 5 minutes, the actual operation needs to be adjusted according to different roller mesh.

4) The essence of ultrasonic cleaning is not to achieve the purpose of cleaning by vibration, vibration is only the inevitable byproduct of the transducer at work; The higher the mass density of the cleaned object will produce a co-shock effect, so as long as there is no defect, the general microshock will not have consequences. But the ceramic roller is a high density and brittle items, such as damage cracks, common shock will easily make it more expanded (metal roller does not have this situation), so carefully check before cleaning. However, the cracked ceramic mesh roller itself belongs to the damaged mesh roller, and even if you do not use the ultrasonic cleaning machine to clean it by other methods, it is extremely easy to aggravate the damage, just as the cracked bowl and other porcelain are easily damaged.
