    選擇合適的超聲波清洗機頻率的條件
    2019-09-19 10:52:02
    超聲空化閥值和超聲波的頻率有密切關係,頻率越高,空化閥越高。超聲波清洗機換句話說,頻率低,空化越容易產生,而且在低頻情況下液體受到的壓縮和稀疏作用有更長的時間間隔,使氣泡在崩潰前能生長到較大的尺寸,增高空化強度,有利於清洗作用。
    There is a close relationship between the threshold of ultrasonic cavitation and ultrasonic frequency, the higher the frequency, the higher the cavitation valve. Ultrasonic cleaning machine, in other words, low frequency, the more prone to cavitation, and in low frequency liquid by compression and rarefaction has longer time intervals, the bubble before the crash can grow to a larger size, higher cavitation intensity, facilitates the cleaning effect.
    所以低頻超聲清洗適用於大部件表麵或者汙物和清洗件表麵結合度高的場合。但易腐蝕清洗件表麵,不適宜清洗表麵光潔度高的部件,而且空化噪音大。40 KHZ左右的頻率,在相同聲強下,產生的空化泡數量比頻率為20KHZ時多,穿透力較強,宜清洗表麵形狀複雜或有盲孔的工件,空化噪音較小,但空化強度較低,適合清洗汙物與被清洗件表麵結合力較弱的場合。
    So low frequency ultrasonic cleaning is suitable for large parts of the surface or dirt and cleaning parts of the high degree of combination of occasions. However, it is easy to clean the surface of the cleaning parts, it is not suitable for cleaning parts with high surface finish, and the cavitation noise is high. About 40 kHz frequency. In the same sound intensity, cavitation bubble number frequency is 20kHz much, strong penetrating power, should be cleaning the surface with complex shape or a blind hole in the workpiece, cavitation noise smaller, but cavitation intensity is low, suitable for cleaning dirt and cleaning surface binding force is weak.
    高頻超聲清洗適用於計算機,微電子元件的精細清洗;兆赫超聲清洗適用於集成電路芯片、矽片及波薄膜的清洗,能去除微米、亞微米級的汙物而對清洗件沒有任何損傷。因此從清洗效果及經濟性考慮,頻率一般選擇在20—130KHZ範圍,當然正確選擇頻率至關重要,而具體合適的工作頻率的選取需要做一定的實驗取得。
    High frequency ultrasonic cleaning for computer, microelectronic components cleaning fine; MHz ultrasonic cleaning is suitable for integrated circuit chips, wafers and thin film wave cleaning, can remove micron, submicron dirt and cleaning without any damage. So considering the cleaning effect and economy. The general frequency selection in 20 - 130KHz for range, of course, correct choice of frequency is very important, and specific appropriate working frequency selection requires do some experimental results.
