超声波为什么能产生清洗的功能?

你见过超声波清洗设备吗?其实,这种设备现在已经很流行了,在很多眼镜店里,清洗镜框和镜片的都是超声波清洗机。这种设备上半部分是一个盛满水的水槽,下半部分是一个超声波发生器。只要一打开开关,只见一片片雾状的“气泡”不停地升腾到水面,激起阵阵水花。
Have you ever seen ultrasonic cleaning equipment? In fact, this kind of equipment is now very popular. In many glasses stores, ultrasonic cleaning machines are used to clean the frames and lenses. The upper part of the device is a water tank filled with water, and the lower part is an ultrasonic generator. As soon as you turn on the switch, you can see a piece of foggy "bubbles" rising to the surface of the water and arousing bursts of water spray.
其实,水里的这些气泡并没有“气”,都是真空的,是由超声波产生的气穴,正确的名称应该是“微小真空核群”,它是无数微小真空核的集合体。气穴酷似分布在宇宙中的无数的银河,可以被称为“微小银河”。这种真空核在液体中一边以每秒2万次以上的频率重复着生成、消减的过程,一边还在高速移动。超声波清洗的秘密就在这里,强力超声波在液体中引发剧烈的振荡,利用真空核的生成和消失时的正负冲击力进行清洗。
In fact, these bubbles in the water have no "gas". They are all vacuum. They are cavitation generated by ultrasound. The correct name should be "micro vacuum core group", which is the aggregation of countless micro vacuum cores. Air pockets are like countless galaxies in the universe, which can be called "tiny galaxies". This vacuum core is still moving at a high speed while repeating the process of generation and reduction at a frequency of more than 20000 times per second in the liquid. The secret of ultrasonic cleaning is here. Strong ultrasonic waves cause violent oscillations in the liquid and use the positive and negative impact force when the vacuum core is generated and disappears for cleaning.

超声波清洗技术已有30多年的历史,但是,对这项技术一直存在一个误解,使人们怀疑超声波清洗的效果。传统的超声波清洗理论认为,气泡起到了清洗的作用。后来经过反复试验发现,事实上,气泡只是由超声波的强力粗密波引起的单纯的气体爆发而已,它反而会抑制甚至消除超声波清洗的清洗力,真正发挥清洗作用的是真空的气穴。这一发现实现了超声波清洗领域的革命性突破。这就是超声波清洗的新理论。以此为基础的超声波清洗技术定义为新超声波清洗技术。
Ultrasonic cleaning technology has a history of more than 30 years, but there has been a misunderstanding about this technology, which makes people doubt the effect of ultrasonic cleaning. The traditional ultrasonic cleaning theory holds that bubbles play a role in cleaning. After repeated experiments, it was found that, in fact, the bubble is only a simple gas explosion caused by the strong coarse and dense wave of ultrasonic wave. Instead, it will inhibit or even eliminate the cleaning force of ultrasonic cleaning. What really plays the role of cleaning is vacuum cavitation. This discovery has achieved a revolutionary breakthrough in the field of ultrasonic cleaning. This is the new theory of ultrasonic cleaning. The ultrasonic cleaning technology based on this is defined as the new ultrasonic cleaning technology.
人们根据这一理论研制的超声波清洗设备,清洗效果大大优于同类产品,能够成功地控制气穴现象的发生位置、发生密度、发生效率和冲击力。最早的超声波清洗技术,大量使用三氯乙烯、氟里昂等有毒有害的化学溶剂作为清洗介质,对环境的污染相当严重,甚至有人因为饮用了受污染的水而过早死亡。后来人们开发了更高效的清洗技术,可以用水代替氟里昂等有毒有害介质,而且更加环保,因此在1993年,这项技术获得美国环境保护局所颁发的环境保护奖。
The ultrasonic cleaning equipment developed according to this theory has a much better cleaning effect than similar products, and can successfully control the location, density, efficiency and impact force of cavitation. The earliest ultrasonic cleaning technology used a large number of toxic and harmful chemical solvents such as trichloroethylene and freon as cleaning media, which caused serious environmental pollution and even premature death due to drinking contaminated water. Later, people developed more efficient cleaning technology, which can replace toxic and harmful media such as Freon with water, and is more environmentally friendly. Therefore, in 1993, this technology won the Environmental Protection Award issued by the U.S. Environmental Protection Agency.
超声波除了可以对金属、塑料、橡胶、液晶等各种部品进行去毛刺和精密清洗外,也可应用于食品,如淘米、洗菜、清洁餐具、洗涤衣服以及医疗用品等的洗涤,此外还可以进行超声波高速腐蚀、超声波颗粒研磨、超声波有机合成等,发展的前景十分广阔。利用这种技术还可以开发超声波洗衣机,除了水之外,无需洗衣粉或洗衣液,这种洗衣机一旦研制成功,将是洗衣业的一场革命,不仅工作效率大大提高,而且可以解决洗衣粉的污染问题。
In addition to deburring and precision cleaning of metal, plastic, rubber, liquid crystal and other components, ultrasonic can also be used in food, such as rice washing, vegetable washing, tableware cleaning, clothes washing and medical supplies. In addition, it can also carry out ultrasonic high-speed corrosion, ultrasonic particle grinding, ultrasonic organic synthesis and so on. The development prospect is very broad. This technology can also be used to develop ultrasonic washing machines. In addition to water, there is no need for washing powder or washing liquid. Once this washing machine is successfully developed, it will be a revolution in the washing industry. It will not only greatly improve the work efficiency, but also solve the pollution problem of washing powder.
