很多人第一次用超声波清洗机都会震惊：眼镜扔进去，水面上飘出一层灰白色的雾，镜片边缘的油膜肉眼可见地裂开、脱落。明明没加洗涤剂，也没人动手擦，它凭什么洗得比手洗干净？

Many people are shocked when they first use an ultrasonic cleaning machine: when glasses are thrown in, a gray white mist floats on the water surface, and the oil film on the edge of the lens visibly cracks and falls off. Why does it wash better than hand washing when no detergent is added and no one is wiping it?

答案藏在两个字里：空化。

The answer is hidden in two words: cavitation.

超声波在液体中传播时，会交替产生正压和负压。负压区的液体被“撕开”，形成无数肉眼看不见的微小气泡。这些气泡在正压区瞬间崩溃，崩溃的瞬间产生超过1000个大气压的冲击波。这个力量有多大？足以在铝箔上打出密密麻麻的孔洞。换句话说，你的眼镜缝隙里、剃须刀网的孔洞里、珠宝爪镶的底部，每一个角落都在被无数个“微型炸弹”同时轰炸。手洗只能接触表面，超声波洗的是立体空间。

When ultrasound propagates in liquid, it alternately generates positive pressure and negative pressure. The liquid in the negative pressure zone is' torn apart ', forming countless tiny bubbles that are invisible to the naked eye. These bubbles collapse instantly in the positive pressure zone, producing a shock wave of over 1000 atmospheres at the moment of collapse. How powerful is this? Enough to create dense holes on aluminum foil. In other words, every corner of your glasses, razor mesh holes, and jewelry claws is being bombarded by countless' micro bombs' at the same time. Hand washing can only touch the surface, ultrasonic washing is for three-dimensional space.

频率决定脾气：低频猛，高频柔。

Frequency determines temperament: strong at low frequencies, soft at high frequencies.

选频率的逻辑很直接：频率越低，空化气泡越大，冲击力越猛，但可能损伤精密表面；频率越高，气泡越小，清洗越细腻，适合高精度工件。

The logic of frequency selection is very direct: the lower the frequency, the larger the cavitation bubbles and the stronger the impact force, but it may damage the precision surface; The higher the frequency, the smaller the bubbles, and the finer the cleaning, suitable for high-precision workpieces.

28kHz是工业通用档，去油污、除锈、清除抛光膏，劲头足，适合五金件、汽车零件、发动机部件。40kHz是精密档，眼镜、首饰、医疗器械、实验器皿，清洁力和安全性平衡得非常好。80kHz以上属于“温柔模式”，用于半导体晶片、光学镜片、硬盘磁头这类对表面完整性要求出色的场景。家用场景选40-45kHz基本不会错。

28kHz is an industrial universal range, used for removing oil stains, rust, and polishing paste. It is powerful and suitable for hardware, automotive parts, and engine components. 40kHz is the precision range, with the best balance between cleaning power and safety for glasses, jewelry, medical equipment, and laboratory vessels. Above 80kHz belongs to the "gentle mode", which is used in scenarios such as semiconductor chips, optical lenses, and hard disk heads that require extremely high surface integrity. Choosing 40-45kHz for household scenarios is basically not wrong.

有几个坑，踩了就知道疼。

There are a few pitfalls, and stepping on them will cause pain.

第一，千万别空烧。槽里没水就开机，换能器空振发热，几分钟就能烧坏。这是超声波清洗机非常常见的“死法”。

Firstly, do not burn it empty. If there is no water in the tank, turn on the power and the transducer will vibrate and heat up, which can burn out in a few minutes. This is the most common "dead end method" for ultrasonic cleaning machines.

第二，别拿易燃液体当清洗液。汽油、酒精、天那水倒进去，超声波产生的热量加上空化效应，就是一套“点火装置”。清洗液用中性水基型或者专用清洗剂，别自己发明配方。

Secondly, do not use flammable liquids as cleaning agents. Gasoline, alcohol, and water are poured in, and the heat generated by ultrasound combined with cavitation effect is a set of "ignition devices". Use neutral water-based or specialized cleaning agents for cleaning solution, do not invent your own formula.

第三，不是所有东西大多能洗。珍珠、绿松石、琥珀、象牙、木制印章、有裂纹的宝石、镀层已经起皮的饰品，这些要么软，要么有缝隙，要么怕振动，扔进去就是毁容。偏光镜片、隐形眼镜也不行。

Thirdly, not everything can be washed. Pearls, turquoise, amber, ivory, wooden seals, cracked gemstones, and jewelry with peeling coatings are either soft, have gaps, or are afraid of vibration. Throwing them in would be disfigured. Polarized lenses and contact lenses are also not suitable.

日常维护就三件事：用完倒水擦干，别让槽里积水长垢；换液前断电拔插头；连续工作别超过30分钟，中间歇几分钟散热。机器不娇贵，但怕懒。

There are three things to do for daily maintenance: pour water and wipe dry after use, don't let the tank accumulate water and dirt; Turn off the power and unplug the plug before changing the fluid; Do not work continuously for more than 30 minutes, take a few breaks in between to dissipate heat. Machines are not delicate, but they are afraid of laziness.

超声波清洗的本质，是把“洗”这件事从表面接触升级成了空间作用。频率选对、液体用对、别空烧、别乱洗，这四条守住了，它就能把那些手够不到的地方，一次洗干净。

The essence of ultrasonic cleaning is to upgrade the task of "washing" from surface contact to spatial effect. By selecting the right frequency, using the right liquid, avoiding empty burning, and avoiding indiscriminate washing, it can clean areas that are out of reach with just one go.
