The advantage of ultrasonic degassing equipment is that the foam is a large number of bubbles. The ultrasonic degassing equipment is used to defoaming and degassing liquid before the beginning of the bubble formation, before the bubbles are gathered in large quantities, or to deactivate and deactivate the gas dissolved and mixed in the liquid. The whole process does not use any defoamer. It is a complete physical defoaming method, which can also be called mechanical defoaming method. For the surface foam that has been generated, the device has no obvious effect and needs to be solved in conjunction with the defoaming film.

脫氣主要運用的是超聲的“定向擴(kuò)散”，一旦產(chǎn)生空化，內(nèi)部還是有空氣，在一些熔融液脫氣純化應(yīng)用中以不產(chǎn)生空化佳。液體的空氣排掉，減少超聲波空化反應(yīng)產(chǎn)生的汽泡的阻力，增強(qiáng)超聲波清洗機(jī)的清洗效率。還有一種作用就是超聲波清洗機(jī)工作時間久了會產(chǎn)生一種超聲波疲勞，減低清洗效果和效率，排氧脫氣功能還可以消除這種超聲波疲勞。

Degassing mainly uses ultrasonic "directional diffusion". Once cavitation occurs, there is still air inside. In some melt degassing and purification applications, it is best not to produce cavitation. The liquid air is discharged to reduce the resistance of bubbles generated by ultrasonic cavitation reaction and enhance the cleaning efficiency of ultrasonic cleaning machine. Another function is that the ultrasonic cleaning machine will produce ultrasonic fatigue after working for a long time, which can reduce the cleaning effect and efficiency. The oxygen exhaust and degassing function can also eliminate this ultrasonic fatigue.

綜上，可以看出超聲波清洗設(shè)備的脫氣功能是非常強(qiáng)大的，而納博科超聲生產(chǎn)的超聲波清洗機(jī)都標(biāo)配集成有脫氣功能，能更好的達(dá)到清洗目的，提高清洗效果。

In conclusion, it can be seen that the degassing function of ultrasonic cleaning equipment is very powerful, and the ultrasonic cleaning machines produced by naboko ultrasonic are equipped with degassing function as standard, which can better achieve the purpose of cleaning and improve the cleaning effect.

超聲波引入溶液中時，會產(chǎn)生交替壓力，用于空化閾的聲波在液體中傳播時能夠產(chǎn)生空化氣泡并且能顯著提高氣體從溶液中到氣泡的傳質(zhì)速率。空化氣泡由溶液中微小的氣核產(chǎn)生，在聲波的稀疏相內(nèi)由于張應(yīng)力（負(fù)壓力）的作用會產(chǎn)生這些空泡。

When the ultrasonic wave is introduced into the solution, it will produce alternating pressure. When the acoustic wave used for cavitation threshold propagates in the liquid, it can produce cavitation bubbles and significantly improve the mass transfer rate of gas from the solution to bubbles. Cavitation bubbles are produced by tiny gas nuclei in solution. These bubbles will be produced due to the action of tensile stress (negative pressure) in the sparse phase of sound wave.

如果張應(yīng)力在空泡形成后繼續(xù)存在，此時空化泡就會擴(kuò)張到初始尺寸的許多倍。在這種情況下，空化泡保持球形結(jié)構(gòu)，之后不斷地增長、振動、崩潰。超聲波作用時，溶液中氣體成分可通過氣-液界面“定向擴(kuò)散”進(jìn)入空化氣泡，空化氣泡進(jìn)人生長階段，當(dāng)空化氣泡在溶液表面崩潰時，氣體會從氣泡中逸出，這就造成了脫氣作用。

If the tensile stress continues to exist after the cavitation is formed, the cavitation bubble will expand to many times its initial size. In this case, the cavitation bubble maintains a spherical structure, and then continues to grow, vibrate and collapse. Under the action of ultrasonic, the gas components in the solution can enter the cavitation bubble through the "directional diffusion" of the gas-liquid interface, and the cavitation bubble enters the growth stage. When the cavitation bubble collapses on the surface of the solution, the gas will escape from the bubble, resulting in degassing.
