實(shí)驗(yàn)室超聲波清洗機(jī)的使用用途!

來(lái)源:http://m.6131420.com/ 時(shí)間: 2022-04-14 瀏覽次數(shù): 0

實(shí)驗(yàn)室作為科學(xué)研究的搖籃,每天需要進(jìn)行各類實(shí)驗(yàn),在實(shí)驗(yàn)過(guò)程中使用的各種儀器配件、容器 、工具如試管、燒杯、載玻片、電子天平、棱鏡、鑷子、夾子等都需要完全清潔后才能用于下一次實(shí)驗(yàn)。而對(duì)于一些復(fù)雜的清洗對(duì)象,用手工清洗不容易洗干凈。污染的儀器配件、容器、工具會(huì)影響實(shí)驗(yàn)數(shù)據(jù)的準(zhǔn)確性。
As the cradle of scientific research, the laboratory needs to carry out various experiments every day. All kinds of instrument accessories, containers and tools used in the experiment, such as test tubes, beakers, glass slides, electronic scales, prisms, tweezers and clips, need to be completely cleaned before they can be used in the next experiment. For some complex cleaning objects, manual cleaning is not easy to clean. Contaminated instrument accessories, containers and tools will affect the accuracy of experimental data.
所以,越來(lái)越多的實(shí)驗(yàn)室意識(shí)到超聲波清洗的方便性與實(shí)用性,將超聲波清洗機(jī)作為實(shí)驗(yàn)室的必備儀器。
Therefore, more and more laboratories realize the convenience and practicability of ultrasonic cleaning, and take ultrasonic cleaning machine as the necessary instrument in the laboratory.
那么,超聲波清洗機(jī)究竟是臺(tái)什么樣的儀器,它的工作原理是什么呢?除了用作實(shí)驗(yàn)室清洗,超聲波清洗機(jī)還能用于哪些領(lǐng)域呢?
So, what kind of instrument is the ultrasonic cleaning machine and what is its working principle? In addition to being used for laboratory cleaning, what fields can ultrasonic cleaning machines be used in?
接下來(lái)我們就來(lái)一起了解一下吧。
Next, let's get to know it together.
A什么是超聲波清洗?
A what is ultrasonic cleaning?
頻率高于20KHz(每秒20,000次振蕩)的振蕩稱為超聲波。當(dāng)這些振蕩作用在液體中時(shí),在拉伸階段,液體中會(huì)產(chǎn)生數(shù)百萬(wàn)個(gè)微小的真空氣泡,這些真空氣泡在壓力階段內(nèi)爆,從而產(chǎn)生局部高能量的壓力沖擊,這個(gè)過(guò)程叫做空化。與40 KHz左右的較高頻率相比,28 KHz左右的低頻產(chǎn)生更大直徑的氣泡,具有更強(qiáng)烈的壓力沖擊,針對(duì)不同的清洗任務(wù)應(yīng)選擇不同的超聲頻率。
Oscillations with frequencies higher than 20kHz (20000 oscillations per second) are called ultrasonic waves. When these oscillations act on the liquid, millions of tiny vacuum bubbles will be generated in the liquid in the stretching stage. These vacuum bubbles implode in the pressure stage, resulting in local high-energy pressure shock. This process is called cavitation. Compared with the higher frequency of about 40 kHz, the low frequency of about 28 kHz produces bubbles with larger diameter and stronger pressure impact. Different ultrasonic frequencies should be selected for different cleaning tasks.
B超聲波是如何工作的?
How does B-ultrasound work?
空化導(dǎo)致污染物從清洗對(duì)象的表面、凹處和孔中被震蕩出來(lái),加上有針對(duì)性的清洗液,可以快速有效的達(dá)到清洗目的。超聲波在幾分鐘內(nèi)清洗的效率超過(guò)任何手動(dòng)清洗。同時(shí),它是溫和的,因?yàn)樗苊饬藱C(jī)械損壞,也避免了化學(xué)腐蝕。
Cavitation causes pollutants to be shaken out from the surface, recess and hole of the cleaning object. With targeted cleaning fluid, the purpose of cleaning can be achieved quickly and effectively. Ultrasonic cleaning is more efficient than any manual cleaning in a few minutes. At the same time, it is mild because it avoids mechanical damage and chemical corrosion.
C選擇什么尺寸的超聲波清洗機(jī)?
C what size ultrasonic cleaning machine do you choose?
超聲波清洗機(jī)設(shè)備
清洗對(duì)象的大小決定了清洗籃的大小,從而決定了所需設(shè)備的型號(hào)。為了使超聲波能夠從各個(gè)方面起用,建議選擇稍大一點(diǎn)的設(shè)備,這也為將來(lái)擴(kuò)展提供了回旋的余地。
The size of the cleaning object determines the size of the cleaning basket, which determines the model of the required equipment. In order to make ultrasound work from all aspects, it is suggested to choose a slightly larger equipment, which also provides room for future expansion.
清洗的難度取決于清洗對(duì)象的幾何形狀和污染物的類型。對(duì)于復(fù)雜的清洗任務(wù),建議增加預(yù)處理工序,例如蒸汽清洗或噴淋清洗。
The difficulty of cleaning depends on the geometry of the cleaning object and the type of pollutants. For complex cleaning tasks, it is recommended to add pretreatment processes, such as steam cleaning or spray cleaning.
D超聲波清洗時(shí)需要加熱嗎?
D do you need heating during ultrasonic cleaning?
經(jīng)過(guò)加熱的清洗液有利于縮短清洗時(shí)間,可以更快的去除污染物 。所以對(duì)于各類清洗對(duì)象的清洗,通常使用帶有加熱裝置的清洗設(shè)備。
The heated cleaning solution can shorten the cleaning time and remove pollutants faster. Therefore, for the cleaning of various cleaning objects, the cleaning equipment with heating device is usually used.
E為什么超聲波工作時(shí)水會(huì)變熱?
E why does water get hot when ultrasound works?
帶加熱的超聲波清洗設(shè)備具有溫度設(shè)定功能,當(dāng)達(dá)到設(shè)定溫度時(shí),加熱器關(guān)閉,但由于超聲波空化會(huì)使受作用的液體變暖,同時(shí)超聲波的機(jī)械能也會(huì)有一部分轉(zhuǎn)化為熱能,這會(huì)導(dǎo)致清洗液的升溫。
The ultrasonic cleaning equipment with heating has the function of temperature setting. When the set temperature is reached, the heater will be turned off. However, due to ultrasonic cavitation, the affected liquid will be warmed. At the same time, part of the mechanical energy of ultrasonic will be converted into heat energy, which will lead to the temperature rise of cleaning liquid.
F超聲波會(huì)損壞零件嗎?
F will ultrasonic waves damage parts?
每秒有數(shù)以千計(jì)的空化氣泡內(nèi)爆,這是非常強(qiáng)大的。然而,超聲波清洗是一個(gè)非常安全的過(guò)程,因?yàn)槟芰刻幱?ldquo;微觀”水平, 空化氣泡的直徑僅為1-3納米!
Thousands of cavitation bubbles implode every second, which is very powerful. However, ultrasonic cleaning is a very safe process, because the energy is at the "micro" level, and the diameter of cavitation bubbles is only 1-3 nm!

允許使用哪些液體?
What liquids are allowed?
請(qǐng)根據(jù)清洗對(duì)象的材料和污染物的類型仔細(xì)選擇清洗液。不適當(dāng)?shù)那逑匆簳?huì)損壞零件。請(qǐng)勿直接在振動(dòng)槽中使用易燃或爆炸性液體!
Please carefully select the cleaning fluid according to the material of the cleaning object and the type of pollutants. Improper cleaning fluid can damage parts. Do not use flammable or explosive liquids directly in the vibration tank!
是否需要保護(hù)聽(tīng)力?
Is hearing protection required?
如果在設(shè)備周圍連續(xù)工作,建議使用聽(tīng)力保護(hù)器或者購(gòu)買隔音箱。
If you work continuously around the equipment, it is recommended to use a hearing protector or buy a sound isolating box.
一次可以清洗多少零件?
 how many parts can be cleaned at a time?
清洗對(duì)象各部分不應(yīng)重疊。在各清洗對(duì)象之間必須有足夠的自由空間,散裝物料必須松散分配。在此基礎(chǔ)上,可以盡量多的放置清洗零件。
Each part of the cleaning object shall not overlap. There must be enough free space between cleaning objects, and bulk materials must be distributed loosely. On this basis, you can place as many cleaning parts as possible.
