The frequency range in which an ultrasonic cleaning machine is used depends on the shape and material of the cleaning. The cavitation effect determines the cleaning effect, and the ultrasonic frequency directly affects the cavitation effect. In general, the cavitation effect of the ultrasonic frequency of 20 kHz-80 kHz is the most appropriate, but in the ultrasonic cleaning machine which frequency is used more? Here's a quick rundown.
Ultrasonic cleaning machines gradually replaced the traditional impregnation, brushing, pressure cleaning, vibration cleaning agent, and steam cleaning process, ultrasonic cleaning machines have high efficiency and high cleanliness, because of the permeability of acoustic waves and cavitating shock waves in the medium, the appearance is complicated, and the pores and internal joints are easy to be cleaned. The frequency of ultrasonic cleaning is generally 25 kHz ~ 130 kHz, but the commonly used working frequency is 28 kHz ~ 40 kHz.
Due to the low frequency below 40KHz is usually called. The easier the cavitation on the road, the lower the wavelength, the greater the intensity, the stronger the effect, and the easier it is to circumvent the object. For example, concrete has many small stones, usually suitable for coarse, dirty, and the initial cleaning of the workpiece; ultrasonic high-frequency directivity, suitable for fine objects cleaning. So 40KHz ordinary industrial parts or dirt more industry use the following working frequency, such as hardware machinery parts de-oiling wax. KHz above working frequency is used for precision cleaning, such as optical, optoelectronic glass devices, List of semiconductor materials, devices, etc.
Industrial ultrasonic cleaning machine, high-pressure spray cleaning machine, hydrocarbon vacuum ultrasonic cleaning machine, semiconductor cleaning machine, mobile phone glass cleaning machine frequency of 28 kHz to 40 kHz, the frequency of ultrasonic cleaning machine can be chosen only if the frequency of cleaning material is known accurately.
Can the ultrasonic cleaning machine wash the key cap?
Earlier, researchers found that one of the dirtiest things in the world is not sludge, but the keyboard that almost every commuter touches every day! Not to mention the dirty keyboard. A keyboard is a tool we come into contact with in our work, and a good place to hide dirt. 2G of sundries are deposited every day, including but not limited to hair, dust, soot, perspiration, grease, and snack crumbs... ? ... Do you ever feel the urge to take your keyboard off and clean it? So how do you clean your keyboard? Does the ultrasonic cleaning function clean the key cap? Let us explain
At present, people know little about using ultrasonic cleaning machines to clean the keyboard, usually using the manual cleaning method to clean the keyboard. Clean the keyboard with a damp cloth. However, while a wet rag can remove some of the dirt on the keyboard's surface, most of the viruses hidden in the space between the keys remain on the keyboard. At the same time, the water in the Wet Rag is easy to infiltrate into the keyboard gap under the scrubbing pressure, resulting in oxidation or rust of keyboard components.
Some maintenance departments or manufacturers that make keyboards use ultrasonic cleaners to clean them, while computer repair shops do a small amount of cleaning, usually with a small ultrasonic cleaner with a single slot. The manufacturer will select the dimensions and associated functions of the cleaning equipment according to its production, cleaning, and cleaning requirements.
If you're concerned about the cleanliness of your keyboard, why not try using an ultrasonic cleaner and a special cleaning agent for your computer that won't scratch the surface of your keyboard, and it can clean small gaps and holes with high precision, completely kill the dirt cap ultrasonic cleaning machine based on the principle of cavitation effect, mainly through the ultrasonic vibrator in the cleaning tank to spread the medium, resulting in tens of thousands of small bubbles, these bubbles exist in the liquid and vibrate under the action of the sound field. When the air pressure reaches a certain value, the bubbles increase rapidly, expand continuously and close the explosion, causing them to separate from the surface of the object and disperse into the cleaning solution, emulsified oil, and separation of collective particles, to achieve the goal of cleaning the surface of components.
