超聲波清洗機有輻射嗎？

作者：admin來源：http://www.heqingliang.cn/時間：2020-11-19

使用過超聲波清洗設備的人，都知曉超聲波清洗器工作時會發出令人感覺不舒適的聲響，這種聲響就是超聲波清洗高頻工作發出的，那人們心里就會有疑問，這樣的超聲波設備有輻射嗎？其實這是不用擔心的，雖然絕大部分電子設備都或多或少有輻射，超聲波清洗機也一樣有，但對人體的危害是微乎其微的，畢竟超聲波不同于微波爐的微波。

People who have used ultrasonic cleaning equipment know that the ultrasonic cleaner will make uncomfortable sound when it works. This kind of sound is generated by high-frequency ultrasonic cleaning work. Then people will have questions in their hearts, do such ultrasonic equipment have radiation? In fact, there is no need to worry about this. Although most electronic devices have more or less radiation, and ultrasonic cleaning machines also have the same, the harm to human body is very small. After all, ultrasound is different from microwave in microwave oven.

超聲波的傳輸是需要介質的，這種介質一般是水，所以通常我們要在超聲波清洗機的機槽里加水。超聲波清洗機是利用超聲波高頻振蕩對水分子作用來運行的，能量也被水所吸收，因此不會對人產生什么損害。之所以發出聲音，這聲音并不是超聲波，人是聽不到超聲波的。這還需要超聲波清洗機的原理來解釋：當超聲波作用于液體中時，液體中會產生數以萬計個氣泡，一直爆裂，從而產生能量極大的沖擊波，相當于瞬間產生了幾百度的高溫以及高達上千個大氣壓，這種現象稱為“空化作用”，超聲波清洗利用液體中氣泡爆炸所產生的沖擊波來達到沖刷和清洗工件隙縫內或外表。超聲波會在液體中傳播，使液體與機槽在超聲頻率下一起振蕩，液體與清洗槽振動時都有各自的固有頻率，所以人們在使用超聲波機器時，會聽到這種振蕩中產生的“嘖嘖嘖”的聲音。剛開始可能會聽不習慣，感覺不是很安心，但這是心理作用，實際上對人體并沒有什么危害。

Ultrasonic transmission is the need for medium, this medium is generally water, so we usually need to add water in the tank of ultrasonic cleaning machine. Ultrasonic cleaning machine is to use the ultrasonic high-frequency oscillation of water molecules to run, energy is also absorbed by water, so it will not cause any damage to people. The reason for the sound is that the sound is not ultrasonic. People can't hear it. This also needs the principle of ultrasonic cleaning machine to explain: when the ultrasonic wave acts on the liquid, tens of thousands of bubbles will be produced in the liquid, which will burst all the time, resulting in a shock wave with great energy, which is equivalent to the instantaneous generation of hundreds of degrees of high temperature and up to thousands of atmospheric pressure. This phenomenon is called "cavitation effect". Ultrasonic cleaning uses the bubble explosion in the liquid to generate The shock wave is used to wash and clean the inner or outer surface of the workpiece. The ultrasonic wave will propagate in the liquid, which makes the liquid and the machine groove vibrate together at the ultrasonic frequency. When the liquid and the cleaning tank vibrate, they have their own natural frequencies. Therefore, people will hear the "tut tut" sound produced in the vibration when using the ultrasonic machine. At the beginning, you may not be used to listening and feel uneasy, but this is a psychological effect. In fact, it is not harmful to human body.

超聲波在空氣里傳播的衰減率大，所以超聲波對人體并不會有多大的影響。

The attenuation rate of ultrasonic wave propagation in the air is large, so the ultrasonic wave will not have much impact on the human body.

如果非要說工業超聲波清洗機對人體有傷害，那則是與人體的接觸問題了。在清洗機工作的時間段中，要是不帶著手套就直接去接觸正在工作的超聲水槽里的水，則會感受到微妙的變化，會有感覺不舒服。使用者應盡量避免直接把手放在正在工作的水槽里。如果一定要接觸，為了安全起見應該帶上手套。若還是不太放心的話，那建議在超聲波清洗機工作時，不要長時間呆在機子旁邊，也要盡量少接觸清洗劑。

If we have to say that industrial ultrasonic cleaning machine is harmful to human body, it is the contact problem with human body. During the working period of the cleaning machine, if you directly contact the water in the working ultrasonic water tank without gloves, you will feel subtle changes and feel uncomfortable. The user should avoid putting the handle directly in the sink. If contact is necessary, gloves should be worn for safety. If you are still not at ease, it is recommended that when working in the ultrasonic cleaning machine, do not stay beside the machine for a long time, and also try to contact the cleaning agent as little as possible.
