Some people in the use of ultrasonic cleaning machine, there will be a question, ultrasound will not damage the cleaning of things? Today, I would like to introduce you to.
First of all, let me introduce you to the working principle of ultrasonic cleaning machine.
Is issued by the ultrasonic generator high-frequency oscillation signal, and then through the transducer into a high-frequency mechanical oscillation and spread to the medium, ultrasound in the cleaning fluid sparse and dense forward radiation, so that the liquid flow and tens of thousands of tiny bubbles, the existence of tiny bubbles in the liquid vibration under the action of the acoustic field, when the sound pressure reaches a certain value, the bubble grows rapidly, and then suddenly closed, bubble closure occurs when Shock wave, around which occurs thousands of atmospheric pressure, hundreds of degrees of high temperature, the use of the closure of the explosion shock wave damage insoluble dirt and make it scattered in the cleaning fluid. When the group particles are wrapped in oil and adhering to the surface of the cleaning parts, the oil is emulsified, the solid particles are detached, so as to achieve the purpose of cleaning the surface of the cleaning parts purification due to the inherent penetrating power of ultrasound, so you can clean a variety of complex appearance, the shape of the special objects, small holes and crevices have a good cleaning effect, cleaning no dead space, no sound absorption or sound absorption coefficient of small objects cleaning effect is particularly ideal.
Cavitation is very similar to the bubbles of beer
Ultrasonic cavitation: penetrate the solid material and make the whole liquid medium vibrate and produce cavitation bubbles to destroy the bacterial structure from the inside, so this cleaning method does not exist to clean the dead ends, and the industry has proved that the cleanliness of ultrasonic cleaning, disinfection and sterilization does not leave dead ends, sterilization process does not produce chemical pollution. The cleaning process belongs to the physical cleaning, so usually does not cause any damage to the cleaning material. Because ultrasound has the function of destroying the cell wall, the use of ultrasonic cleaning machine cleaning vegetables and fruits will achieve the removal of pesticide residues and sterilization function.
But it is not recommended to use the ultrasonic cleaning machine to clean some of the more fragile items. For example.
1, no edge-set and micro-set jewelry can not be cleaned with an ultrasonic cleaning machine to prevent the jewels on the jewelry from falling off.
2, organic gemstones, Opal, turquoise, emerald, etc., because the hardness is too low, easy to break.
3, cat’s eye, pearl, jade, tanzanite, malachite, green, ruby, lapis lazuli and coral, because the hardness is too low, easy to break.
4, pearl jewelry, jade, cracking more serious stones also can not be cleaned with ultrasonic.
