超聲波清洗機(jī)有輻射嗎？

作者：admin來(lái)源：http://www.400qy.cn/時(shí)間：2020-11-19

使用過(guò)超聲波清洗設(shè)備的人，都知曉超聲波清洗器工作時(shí)會(huì)發(fā)出令人感覺(jué)不舒適的聲響，這種聲響就是超聲波清洗高頻工作發(fā)出的，那人們心里就會(huì)有疑問(wèn)，這樣的超聲波設(shè)備有輻射嗎？其實(shí)這是不用擔(dān)心的，雖然絕大部分電子設(shè)備都或多或少有輻射，超聲波清洗機(jī)也一樣有，但對(duì)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(zhì)的，這種介質(zhì)一般是水，所以通常我們要在超聲波清洗機(jī)的機(jī)槽里加水。超聲波清洗機(jī)是利用超聲波高頻振蕩對(duì)水分子作用來(lái)運(yùn)行的，能量也被水所吸收，因此不會(huì)對(duì)人產(chǎn)生什么損害。之所以發(fā)出聲音，這聲音并不是超聲波，人是聽(tīng)不到超聲波的。這還需要超聲波清洗機(jī)的原理來(lái)解釋：當(dāng)超聲波作用于液體中時(shí)，液體中會(huì)產(chǎn)生數(shù)以萬(wàn)計(jì)個(gè)氣泡，一直爆裂，從而產(chǎn)生能量極大的沖擊波，相當(dāng)于瞬間產(chǎn)生了幾百度的高溫以及高達(dá)上千個(gè)大氣壓，這種現(xiàn)象稱為“空化作用”，超聲波清洗利用液體中氣泡爆炸所產(chǎn)生的沖擊波來(lái)達(dá)到?jīng)_刷和清洗工件隙縫內(nèi)或外表。超聲波會(huì)在液體中傳播，使液體與機(jī)槽在超聲頻率下一起振蕩，液體與清洗槽振動(dòng)時(shí)都有各自的固有頻率，所以人們?cè)谑褂贸暡C(jī)器時(shí)，會(huì)聽(tīng)到這種振蕩中產(chǎn)生的“嘖嘖嘖”的聲音。剛開(kāi)始可能會(huì)聽(tīng)不習(xí)慣，感覺(jué)不是很安心，但這是心理作用，實(shí)際上對(duì)人體并沒(méi)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(duì)人體并不會(huì)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(shuō)工業(yè)超聲波清洗機(jī)對(duì)人體有傷害，那則是與人體的接觸問(wèn)題了。在清洗機(jī)工作的時(shí)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(huì)感受到微妙的變化，會(huì)有感覺(jué)不舒服。使用者應(yīng)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(jiàn)應(yīng)該帶上手套。若還是不太放心的話，那建議在超聲波清洗機(jī)工作時(shí)，不要長(zhǎng)時(shí)間呆在機(jī)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.
