Many people are asking, is the power of the ultrasonic cleaning machine bigger, the better the cleaning effect, the frequency selection or the high frequency?
Today, I will tell you about the difference between the power and frequency of the ultra-wave cleaning machine, and analyze how to choose the ultrasonic cleaning machine and choose the ultrasonic cleaning machine that is suitable for your own cleaning.
First of all, the power of the ultrasonic cleaning machine, the higher the power of the ultrasonic cleaning machine, the greater the sound intensity, the larger the radius of the cavitation bubble, the greater the cavitation intensity, and the stronger the cavitation, which is beneficial to the cleaning effect, but not the power Larger, the better the cleaning effect, the higher the sound power is, and a large amount of useless bubbles will be generated, which will increase the diffraction attenuation, which will affect the cleaning effect of the parts to be cleaned away from the sound source. Moreover, the cavitation corrosion of the cleaning vibration plate is more serious, resulting in a shorter life of the equipment. However, if the power of the ultrasonic cleaner is too small, the cleaning time may be long or the cleaning effect may be poor. So what kind of cleaning object, what kind of power to choose. For example, if the height of the workpiece is less than 30cm, then the height of the inner groove of the selected ultrasonic cleaning device is about 40cm, and the single vibration can be selected at the bottom, and the power is maintained at 0.3~0.5W per square centimeter. If the workpiece is too large, or the amount of cleaning is too large, the height of the tank we choose is above 40cm, which is generally calculated according to the rising power, and is generally selected at 11w/L.
Then talk about frequency, frequency is also a major factor in the selection of ultrasonic cleaning machine, the frequency determines the cleaning strength. At low frequencies, the time between compression and sparse action of the liquid is longer. Allows the bubble to grow to a larger size and has a stronger force on the surface of the cleaning workpiece. Therefore, in general, the surface of a large part or the high degree of bonding between the dirt and the surface of the workpiece will select a low-frequency ultrasonic cleaning machine, but the low frequency is more likely to damage the surface of the workpiece, so it is not suitable to select a lower frequency for those parts with higher surface requirements. The low frequency noise is correspondingly larger. High-frequency penetration is strong, such as those with high gloss requirements on the surface of the cleaning object or more complicated blind holes on the surface. High frequency noise is small, suitable for cleaning precision parts, such as electronic parts, magnetic materials, small bearing processing; those integrated circuit chips, silicon wafer coatings use higher frequency ultrasonic cleaning machines; like those of motor vehicles, valves Large workpieces are generally cleaned with a low frequency ultrasonic cleaner. The more moderate frequency used in the market is 40KHZ. And if you want to choose the exact frequency, it is best to experiment.
So, everyone is still unable to find a suitable ultrasonic cleaning machine? I think, now you can basically choose your own.
Many people eat and sleep a little in winter and hate dark mornings and short days. This is called "winter blue". Others have more serious symptoms such as sleep disorders, withdrawal symptoms, binge eating, depression, anxiety, and lethargy. These often lead to family, work, and relationship difficulties. This is a perceived problem called seasonal affective disorder (SAD).
SAD is caused by a lack of bright light in winter. The light that enters our eyes stimulates our brain and controls our daily rhythm through the production of hormones. For some people, winter does not have enough light to regulate the hormones that prevent us from getting up and sleeping, being energized, and depressed.
